There is one feature about 100F that may not be too well known. It's exposure range is 1/4000 - 128 seconds WITHOUT any exposure compensation. The feature of some tungsten film in a daylight emulsion - truly fantastic. In addition, it is lower contrast with a wider latitude which makes it perfect for scanning.

Re: Advantage of small f/number!
Hallo Bill! The front element of a 50 mm f/1.4 lens has bigger diameter than a 50 mm f/4 lens. (Am I correct?) Therefore the preliminary amount of light energy reaching an imaginary plane or film behind the lens per unit time per unit area is more than a 50 mm f/4 lens as it has a smaller front element. When it is stopped down to f/4, the amount of light reaching the film plane is more than 50 mm f/4 lens. The above explanation depends only on one point that the front element of a 50 mm f/1.4 lens has bigger diameter than 50 mm f/4 lens, if it is at all correct. However, you are absolutely right that f/4 is still f/4 or in other words, the diameter of the aperture at f/4 is identical in both the cases and therefore, the light has to pass through the holes of identical diameters but what I mean to say is that the intensity of light in 50 mm f/1.4 lens is more than a 50 mm f/4 lens. Please correct me, if I am wrong anywhere. Many thanks for your comments. With best regards, Ayash Kanto. On Mon, 1 Jul 2002, Bill D.

No - they'd be the same since f4 is f4 no matter the lens, etc. It is possible that one may have some indistinguishable difference due to light transmission efficieny, but it is doubtful that it would be significant enough to register except using extremely small latitude emulsions.

Hi Timothy. I also used the 4x6 print,Epson manual mode so i could do the dpi etc adjusting.

Re: Advantage of small f/number!
Hallo Yves! Just a few minutes ago, I replied to Bill. You are absolutely right in your point. I know that quite well. The f-number is defined as the ratio of focal length to the diameter of the aperture (Am I correct?). But I am talking about the preliminary intensity of light reaching the film plane because of the wider diameter of the front element in the case of 50 mm f/1.4. Your reply is of course comprehensible. Many thanks for your reply.

The correct exposure will be obtained with the same shutter speed for both lenses. Actually, that same shutter speed should even give the correct exposure for any lens [*]. This is because f-stops are defined so that this property holds. As a result, for identical f-stops, the actual diameter of the diaphragm will depend on the focal length and the lens design. To go back to your comparison between the two 50 mm lenses, I expect the optical quality of the F1.4 lens to be better at f4 than the F4 lens, though (since you are not pushing your lens to its limits, especially regarding vignetting).

Am i missing something with the size of file vs the constrants in image resize??? Yes you are missing something important :-) You could have changed that resized image (600x400 pixels) to the right display size by adjusting the DPI from 300 to something like 75 in photoshop. That way photoshop will show you a size that is valid for most monitors. Do NOT resample doing this, or you will change the number of pixels again! The size indicated by your imaging program is just an indication and is valid for the (also specified) number of pixels/inch The 300 DPI is used by the scanner and is put in the outputfile so a printer can print it out in the original size. 300 DPI is fine for printer. So if you have 600x400 pixels and 200 pixels/inch (sometimes called PPI or DPI) the size printed would be 3x2 inches. Programs like photoshop can size the image on the screen to match the printing size. Viewing the image in 1:1 scaling however, will use the monitor/graphic card resolution which is usually something like 72 or 75 pixels/inch. You can change the printing size for an image in photoshop without changing the number of pixels. All it needs to do is change the number of pixels/inch. This value is saved with the image so other programs can use the same value again when printing ... A 600x400 pixels image is just that 600 times 400 pixels, that is what defines the resolution of the image when displayed or printed without any further interpolation. On a computer-monitor, the total screen is usually 800x600 or 1024x768 pixels, so an image like 600x400 will easily fit on that. In general, displaying on a computer monitor will NOT change the image resolution by donig a resize or interpolation. So for submission to the PUG it does not really matter, as long as you have 600x400 pixels (or something close to that) you are fine.

Provia is also very fine grained but is no sharper than other 100ISO slide films - some even say its less sharp. Allegedly, Fuji have changed the color response of Provia F after I used it so maybe some of the color problems are sorted out. Anyway, I never use it cause it is prohibitely expensive costing twice as much as comparable filmst. Pål - This message is from the Pentax-Discuss Mail List.

I think Dad's feeling toward son may be just as well expressed by his body language in any event. All in all, a lovely, tender moment. Thanks. Thanks for your compliments -- I liked it too. Will see what I can do about bringing up the face. I'm hoping that they like the photo enough to forgive me for photographing them instead of rushing to the rescue ...

However, the amount of light reaching the film at f4 is identical from lens to lens (by definition of f-stops, and this is why they are useful!). therefore, the light has to pass through the holes of identical diameters but what I mean to say is that the intensity of light in 50 mm f/1.4 lens is more than a 50 mm f/4 lens. I am writing the following quickly, so take it with a pinch of salt: if the F1.4 has the same design than the f4 lens and just has larger front elements, I indeed would guess that the diaphragm opening of the F1.4 lens at F4 should be the same than the size of the diaphragm of the F4 lens wide open.

Re: Advantage of small f/number!
Hi Yves! Your explanation is absolutely clear to me. So, it is the diaphragm which blocks of the extra amount of light collected by lenses with bigger front element. Yeah! I liked the pinch of salt. I am very much thankful to you and Bill. Now, I am in a position to arrive at the second stage of the drama. I was watching world cup football on TV and there I saw that all the photographers are equipped with small f-number lenses, seemed to be 300 mm f/2.8 kind. They must be shooting at shutter speed of 1/125 th of second in order to stop the action. Now the light in an artificially illuminated stadium is too low. The solution to the problem is to use a fast film and a steady tripod since the focal length is too large to hand hold the set-up. I shall like to know what aperture do they use with what film speed? Do they use those big lenses to take an advantage of f/2.8 or do they always shoot at wide open apertures? (I don't think so as the photographs appear quite sharp with good depth of field (3 m) in the sports magazine) I can put the question in another manner. Suppose I have a 300 mm f/5.6 lens. What film speed should I use in order to stop the action as well as attaining good depth of focus (say, 4 m) in an artificially illuminated stadium? I apologize for this kind of complicated question. I am just inquisitive, that's all. Many thanks for explanation. It cleared a lot of doubts. With best regards, Ayash.

Re: Advantage of small f/number!
Ayash Kanto Mukherjee wrote: You are absolutely right in your point. I know that quite well. The f-number is defined as the ratio of focal length to the diameter of the aperture (Am I correct?). Yep - so the light-gathering of the bigger front element will get funneled down to the same as the f4 when stopped down to f4 But I am talking about the preliminary intensity of light reaching the film plane because of the wider diameter of the front element in the case of 50 mm f/1.4. The intensity of the source doesn't enter into things. Unless it differs between the time you use the f1.4 and the time you use the f4, an autometering system will give the same shutter speed at any given f-stop. Things do look brighter in the viewfinder w/ the f1.4, but when stopped down this disappears. Bill - Bill D.

I'm maxed out at 512MB and it helps when you've got more than one image in memory, like batch scanning. 1GB is not too much if you want to batch scan all six frames in the negative carrier at once at full resolution. Not a problem. I have 512... I'd have 1Gb by now if it wasn't for Win ME. I don't plan on doing batch scanning. That allows you to scan an entire roll of APS film at once. I hate to think how much memory that takes at full resolution. Who cares ;) I do wish it could scan true panoramas (mine are 24x68mm). The HP S20 is the only 35mm scanner I know of that can do this. But thats a minor point as my Arcus 1200 can handle those, if my calibration slide ever turns up. Scanning a frame at 4000 dpi, 42-bit color, with FARE (IR scratch/dust removal) enabled, will take around ten to fifteen minutes per frame. That's quite a long time but for the price I have to expect to make some tradeoffs. I saw one review posted a couple of samples images with FARE on and off and it looks quite good. Unless you use the strong setting there appears to be very little, if any, image degradation. Rather than using FARE I will start by just cleaning the slide and rubber- stamping dust out. If thats too much of a chore I'll put the FARE on :) The vast majority of this time seems to be the actual scanning. It doesn't look like changing from USB to SCSI would help much, as a fraction of the total time. It seems like it might knock off fifteen to thirty seconds, but that seems to be about it. I had to buy a SCSI card for the Arcus 1200 so I'll buy another cable and hook it onto that. The Canon scanner only supports USB1.1 which isn't exactly blazingly fast for this kind of application. USB2.0 is a lot faster. FARE works very well, but big scratches or hairs or things will cause it to fail. The bummer is that the driver doesn't detect the failure until after the entire scan is done, then it throws away the image due to the failure. Cleaning the negative and rescanning almost always works. I keep a blower-brush at the computer desk and _always_ clean my slides prior to scanning. A five-second brush saves several minutes of retouching... These operational problems are not enough to keep me from using the scanner, though the memory leaks can get me pretty frustrated sometimes. Yeah it does sound a little annoying, but bad software is a lot easier to fix than bad hardware :) Have you tried it with Vuescan? The biggest problem I'm having is what appears to be grain aliasing. It only happens at 4000 dpi, and I'm afraid the only real way to fix it is to go up or down in resolution. I've heard that grain aliasing occurs with all 4000dpi scanners anyway. Do you know what slide films would be like in that case? The films I use most are Kodak E100SW and Fuji Provia 100F (and a few rolls of Velvia). I'm still trying to figure out a really good way to even it out after scanning. The Arcus 1200 driver has an amazingly good descreening function, but that's designed to get rid of regular line-screens from halftoned material. Thanks for the comments, Doug. Do you have any specific comments on the scanner's dynamic range? Cheers, - Dave http://www.digistar.com/~dmann/ (out of date) - This message is from the Pentax-Discuss Mail List.

Re: Carry-on inspection of film -- and an unfortunate incident

I had no fogging problems at all. I'm pretty sure that as recently as March the SFO security gates were still using their same old equipment to screen carry-on baggage. Is there any possibility that he checked the film? Also, I think that APS cartridges are plastic while 35mm canisters are generally metal. Finally, the magnetic information on APS film can include instructions intended for the minilab machinery.

Quite a humbling experience! My favorite is Angels in America, by Richard Seaman. I have attended many airshows, and taken many shots of the Blue Angels and other groups, so I really appreciate what a an excellent piece of work this is. It really captures not only the particular moment in time, but also the essential spirit of the Blue Angels' performance. I also liked the following photos very much, each of which is similar to shots I have attempted often and each of which really grabs the critical moment: Andre Langevin, Bang On Antti-Pekka Virjonen, Comet Ikeya Zhang Kathleen Leickly, Tree Swallows Thibault Grouas, A Colorful Garden Finally, I also liked Woman on Top, by Ollen Malles very much.

Re: A* 600mm f5.6
My advice is to forget using a 2X converter with a 600mm lens. Well, yes and no, Paal... One thing is that no lens will give good result with a 2X converter (in spite of what some people claim, no good 2X converter has ever been made - you get visible image degradation with all 2X converter [snip] Yes, all 2X TC's (and, to a lesser degree, all 1.4X and 1.5X TC's) cause some image degradation. However, sometimes the degradation is small enough, and the use important enough, that such use is justified. In addition, the A 2X-L is a better optical match for the 600/5.6 than are the typical garden-variety 2X TC's with almost any lens. another issue is that a 1200mm lens is virtually impossible to support. Difficult, yes - impossible, no. In addition, you need to stop down at least two stops to get even half decent results from a 2X converter something that gives you a shooting aperture of F:22. Again, this is true for maximum image quality. However, sometimes the use of a TC with a wide open lens is justified. You are going to be constantly plagued by vibration problems and can only shoot still life. Or, you would constantly have to be concerned with, and would constantly have to compensate for, vibration problems. Are you still showing the effects of your frustration with trying to use the 600/4 on a zodiac? g The Pentax 2X-L converter doesn't really work with the 600/4 if you are even the slightest quality concious, at least you need two tripods, so I doubt it will work any better with the 600/5.6. Well, the 600/4 is somewhat longer and ~over~ twice as heavy, so its tripod requirements are a lot more substantial. While both lenses have the same FL, the ~much~ lighter 600/5.6 will tax a tripod's stability significantly less. Related to this is the fact that I can do a reasonably good job of hand-holding the 600/5.6 under bright light conditions, but I doubt that I could ever support the 600/4 without a year's worth of weight training at the local gym - g. The 1.4X-L converter should work great though. I do agree with that point. Fred - This message is from the Pentax-Discuss Mail List.

Re[2]: Advantage of small f/number!
Hi, Suppose I have a 300 mm f/5.6 lens. What film speed should I use in order to stop the action as well as attaining good depth of focus (say, 4 m) in an artificially illuminated stadium? If your subject is 2m in height then to fill the frame using a 300mm lens you must be 17m away. To achieve a depth of field of about 4m your aperture must be at f/16. On a bright day you can do this with ISO 400 film at 1/500 second. According to Michael Freeman in his book Light all stadiums that have TV coverage use multi-vapour lamps, because these produce a colour quality close to normal daylight. He suggests that for ISO 400 film at 1/60 or 1/125 you will need an aperture of f/2.8. So to achieve a depth of field of 4m your film needs to be rated at 12,800. However, most of the photographers are probably using digital cameras, so these calculations may not apply. For example, a nominal 300mm lens is effectively longer than that, and the f-stop ratio is changed, so there may be more depth-of-field than I've indicated. These numbers are for 35mm. --- Bob mailto:[EMAIL PROTECTED] - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.

I can then rotate the screw without bending the wire ends of the paperclip. Works OK for me -- hopefully it may work for others as well. Hi Bill, I use the paper clip method too, cut the clip with flush wire cutters then file the ends smooth, OK for the cap on the advance lever. However in the case of the screw in the middle of the shutter speed dial the holes are so small that if you could find a paper clip of the correct diameter the material would readily deform hence the use of drills. If you use a vice grip in conjunction with drills of paper clips then you can ensure that the assembly will stay rigid and correctly spaced.

Re: Carry-on inspection of film -- and an unfortunate incident
That does bring up an interesting point about the 120/220, though: Nothing to shield it. What have people's experiences been with that getting scanned at airports? t On 7/1/02 3:08 PM, William Robb wrote: - Original Message - From: Bill Owens Subject: Re: Carry-on inspection of film -- and an unfortunate incident My photo lab has a sign up warning customers that they've experienced problems with APS film being fogged by X-ray security machines, but not other film types.

Could it be because APS uses a plastic cassette instead of metal, like 35mm? If so, 120 film should also be fogged This is the likely culprit. The steel film can is pretty X-Ray opaque, with damage coming in via the felt lips and the plastic spool. APS canisters are X-Ray transparent. They are barely visible light tight at best anyway. I would be very hesitant to trust the word of a security goon about the potential damage from any radiation exuding inspection device. They are not trained professionals, they are merely parroting the baboonery from their bureaucrat bosses, who generally take the best case scenario from the manufacturer of the equipment and call it the worst case scenario. Unfortunately with the present level of paranoia, the traveling photographer is best advised to buy his film and processing at the destination, whenever possible, no matter how it impacts the economies of the photographer and his home processing lab. There has never been a guarantee that inspection equipment will not damage film, the damage is cumulative, and is most likely to happen to film that has already been exposed.

From what I understand APS film is manufactured with a magnetic coating over it's entire photosensitive surface it is also a different base material than used for 120 or 135 films polyethylene naphthalate (PEN). Whether the backing affects the films x-ray susceptibility I don't know however the fact that they have a plastic near x-ray transparent shell may. I can't vouch for the susceptibility of 120 films to carry-on x-ray exposure as I have managed to avoid their exposure by having them processed before flying. When I shot APS in my travels I managed to carry it on my person through the metal detectors without a problem so I didn't have to subject it to x-ray inspection. I would guess that had I done so the damage would have been visible considering the number of times my other gear was x-rayed.

Hi Sid; Sorry to take so long to respond. I aimed my Zone VI modified Pentax Digital Spotmeter, and chose a neutral gray area (the street in front of my house). I metered it with no filter, and with a #87 IR cut filter. I got a 7 stop drop with my meter. Is is possible you are getting light leakage around your filter? Also, it is entirely possible that you don't have a modified meter. Does your meter have the Modified by ZoneVI Studios plaque cemented to it or does it just have the zone sticker on the dial? William Robb Hi all, I've been attempting to establish an accurate exposure index for Kodak HIE by using my Zone VI spot meter with an 89b opaque filter in front of the lens. I establish a zone 'V'ish location in the scene to be photographed, like a patch of green grass, and I take a spot reading with and without the 89b filter. Strangely enough, the readings only drop about one stop when I read the same scene with the filter. This violates all my known (allbeit limited) sensibilities about what should happen. If this filter is blocking everything below around 720nmm, and this filter is altered for zone system use by limiting everything above and below (approxmately) visual range, the reading I get should fall tremendously. Obviously the meter does not trap every range above and below visual light; so what is happening here? Is it an important consideration? My goal is not to understand quantum physics, simply have a more accurate way of establishing exposure for a film that defies, or seems to defie, indexing. - This message is from the Pentax-Discuss Mail List.

LowePro Dryzone 200
Hello all... I'm semi-seriously shopping around for a photo backpack; the recent thread on this topic was very informative. I had narrowed it down to a Micro Trekker 200 or an Orion, but during my research, I noticed LowePro has a new pack coming out that appears to be waterproof: the Dryzone 200. http://www.lowepro.com For my purposes, this would be perfect. Right now, I use a wet/dry bag around a camera bag while canoeing. While it keeps my gear dry, It's not ideal for accessing my gear. Pelican cases are another option, but I think I'd look ridiculous with one strapped to my back! Apparently, the Dryzone bag hasn't hit the street yet. But I'm curious to see if anyone seen it or handled it at a trade show or dealer demo. What about prices and construction? TIA, Tim - This message is from the Pentax-Discuss Mail List.

Re: Which Manual Zoom?
Hi! I think that 28-135 mm f/4 is the best option because of the range focal length one gets and also the maximum aperture do not change when the lens is zoomed in. This is great advantage. Why? Because, this lens can be used with automatic flash units because one can set the aperture precisely in any focal length. Please notice that the maximum aperture changes in the case of A28-80mm f/3.5-4.5 and therefore flash photography becomes difficult since you never know the aperture when the lens focal length is set between 28 and 80 mm. Hope it helps. - Ayash. On Mon, 1 Jul 2002, Robert Woerner wrote: What are opinions on the following possibilities?

The intensity of the source doesn't enter into things. Unless it differs between the time you use the f1.4 and the time you use the f4, an autometering system will give the same shutter speed at any given f-stop.

Re[2]: Advantage of small f/number!
Hi! It is quite an informative email. I never knew the details of the lighting in a stadium until I recieved your mail. On Mon, 1 Jul 2002, Bob Walkden wrote: Hi, According to Michael Freeman in his book Light all stadiums that have TV coverage use multi-vapour lamps, because these produce a colour quality close to normal daylight. He suggests that for ISO 400 film at 1/60 or 1/125 you will need an aperture of f/2.8. So, it means that 400 ISO film is not enough. One has to use atleast 1600 ISO film provided that the lens in use is 300 mm f/5.6. So to achieve a depth of field of 4m your film needs to be rated at 12,800. I am shattered. However, most of the photographers are probably using digital cameras, so these calculations may not apply. For example, a nominal 300mm lens is effectively longer than that, and the f-stop ratio is changed, so there may be more depth-of-field than I've indicated. These numbers are for 35mm. Aah! those DIGI-guys are always at an advantage but I don't want to go DIGI. Many thanks for your comment. With best regards, Ayash. - This message is from the Pentax-Discuss Mail List.

Hi Joe! So, you mean that professional photographer are shooting all the time at f/2.8 and hence they possess those lenses becuase they really need that aperture only. Yes, you are right that a monopod will make the life much easier under such situation. Many thanks for your helpful comments. With best regards, Ayash. On Mon, 1 Jul 2002, Joseph Tainter wrote: In regard to shooting a teletphoto lens in a stadium. I would recommend investing in a monopod to steady your shots. With a monopod you can gain 1 or 2 EV over hand-held. For example, a 300 mm. lens should be shot at 1/350. With the monopod, you might go to 1/180 or even 1/90. If the professional photographer with an f2.8 lens shoots 1/350 at f2.8, you could shoot 1/90 at f5.6 and save a great deal of money (that is, by buying an f5.6 lens rather than one that opens to f2.8).

OT:Gossen Multi-Beam spot attachment
I have a Gossen Luna Pro SBC and am thinking about finding a Multibeam spot meter attachment for it. Has anyone used one of these? Does it work well enough that you could recommend buying one over buying a separate spotmeter for travel use? Obviously size and weight are a consideration. Since the SBC is large enough as it is, maybe you could recommend a combination meter that does spot, reflectance and ambient in one, that is as reliable and battery thrifty as the SBC, yet smaller. Oh yeah and it has to do low light as well as the SBC and not cost muchThat's not asking for too much is it? g So back to reality; what do you think of the Multibeam? New! SBC Yahoo!

Re: Advantage of small f/number!
Hi Giafranco! I visited the websites that you have mentioned and can understand the position from where you took the shot. I was suspecting from the beginning that it should be some sort of hilltop because the skycrappers in your photograph look small but I never knew that there is castle with rich history. A great view as if you are on the top of the world and can see rest of the world. I can feel the sensation when somebody goes at such a place. As far as the 50 mm lens problem is concerned, I have understood well now. So, I won't feel much sorry, if I don't have a small f-number lens. Or should I feel sorry? Am I missing something? Thank you so much for such a nice and informative reply. With best regards, Ayash.

Built during the 16th Century on the site of a former, smaller, castle, Castel Sant'Elmo became a prison in the 18th Century until the 1952. It is now a museum and there is kept the photographic archive of the Cultural Superintendence of Naples. You can see many pictures of the castle at: http://progetti.webscuola.it/progetti2000/790/CastelSantElmo.html Too bad the page is in Italian only, but you can clearly see the vault windows I took the picture from. There's a nice but small picture at: http://www.medcruise.com/napo/f01_napo.html The castle is the higher building on the background. The view I took is from the right side (facing NE). I have some doubts regarding lenses with small f-numbers. Suppose you have two lenses, one is 50 mm f/4 and the other is 50 mm f/1.4. If, I stop down the second lens to f/4, which one will give faster shutter speed for correct exposure? The speed will be the same, if you don't change anything: if you compare f/4 of both lenses you'll see that the area enclosed into the diaphragm of the stopped down f/1.4 lens is the same of the aperture of the f/4 lens wide open.

While it keeps my gear dry, It's not ideal for accessing my gear. Pelican cases are another option, but I think I'd look ridiculous with one strapped to my back! Hi Tim, I have the Photo Trekker and a heap of Underwater Kinetics and Pelican case to house my gear, the hard cases aren't real good to trek with however they'll take a gargantuan spill in a canoe :-) Lowepro do have a hard case that fits into a back pack (Omni Trekker) but its huge and heavy. I fit a pair of LX with 3 short lenses and a long lens (100 macro), folding finder plus my Mamiya 7 with two lenses, finder and Gossen meter apart from film and other goodies (I have a pic if you'd like to see how they squash in). The DryZone 200 looks to be only a bit smaller than the PhotoTrekker. Apparently, the Dryzone bag hasn't hit the street yet. But I'm curious to see if anyone seen it or handled it at a trade show or dealer demo. What about prices and construction? For my money the Lowepro gear is worth the cash, the back pack seem to fit pretty well and they're tough, I've ended up on my butt a few times and scraped it pretty badly and it's come through well. Also I always clean my gear after a grubby excursion and the first thing is a good swamping under the hose, if the zips are down up I can give it a drenching before it's wet inside and mine isn't even an AW, so I'd expect that they'd perform as advertised.

I have been looking for a new backpack for quite some time with no real success and now Lowe seems to have made the perfect pack especially for watersports/sailing :-) It just makes me wonder if they will extend the DryZone series to slightly bigger bags as well ... On the other hand, the 200 seems to be quite a perfect size for a portable photo kit with the interior size slightly larger than the Nature Trekker AW.
