filmscanners: VueScan-Silverfast compared.
I have done a little test and looked at VueScan 7.1.2 and Silverfast 5.2 LS4000 new version from Germany. Used scanner in the test LS2000. VueScan can not handle LS4000 and MAC yet. Test object: 3 dimensional test object including Mac Beth , gray scale, black to white objects, silver spoon, map in the background, small round balls, test chart for resolution etc etc. . Controlled studio light situation. Test object for tests of , digital cameras, scanners, films etc. in Photodo magazine ( If you want to know about lens resolution , MTF tests and other things please go to my friend Lars Kjellberg Photodo and member of TIPA . http://www.photodo.com/about/intro.shtml ) Negative film: Fuji 100 ISO. Camera Nikon F5 and micro nikkor . Colors and other results evaluated on MAC OS + LACIE 22 calibrated with Color Vision monitor spyder. Gamma 1.8 Color temp 6500K. Adobe RGB color space in VueScan, Silverfast and Photoshop. VueScan= Excellent in gray scale. no color cast, and very god in red colors. I got the best scanning results to use generic settings with Fuji film and Adobe RGB and gamma 1.4 instead of gamma 2.2. This gives better results between blackness and high lights and contrast in the test object and I have not so much work later on in Photoshop. What can see is: VueScan are not so god in the yellow color (more orange) and green colors are little week and dirty. There are Somme lack of 3 dimension in the picture and some flatness compare to Silverfast. Silverfast have also little more color nuances in details. I have tried to get the same results later on in Photoshop as I can get from Silverfast, but there are still some nuances and 3 dimension missing in the results. Silverfast has a red -pink color cast well known to me and other how have used Silverfast for a long time, it also shown in the gray scale chart in the picture. Red are to intensive but these things are easy to adjust in the scanner software or in Photoshop. All other colors are shown perfectly on the Mac Beth test sine. Conclusion: VueScan are IMO a very good software but can be improved in some details. I can still se that there are some flatness in the pictures produced by VueScan and negative film compared to Silverfast. And a warning. I got serious crashes with VueScan and MacOs. I think its because of that VueScan still use virtual memory ,which on a Mac slows down the computer and gives problem with other programs. I hope Ed Hamrick can get rid of the needs of virtual memory handling in VueScan. VueScan and Silverfast are good working tools, fast scanning speed and excellent results.

Re: filmscanners: Scanner resolution File Sizes ( workflow)

That stands to reason, given the larger size. I'm wondering if there is a program that would save both a TIFF and a much smaller JPEG file to HD, and index them according film strip, date scanned and frame#. Then one could select the best TIFFs and dump the weak ones, but still have good references for future work. If there isn't, it's just an idea and I don't believe too thoroughly in "Intellectual Property"--so feel free to run with it, anyone. If I were a better programmer, I'd start on it tomorrow, and wouldn't have mentioned it today. (I might not believe in IP, but I'm not stupid, either! ;-) ) Best regards--LRA There are probably a number of programs out there that will allow you to do what you are proposing. It's just a matter of locating them. Personally, I use a rather simple method of managing my digital photos that doesn't require any special software and is suited to my needs. I'm sure there are better and faster methods, but the following workflow and method works for me and might give some ideas to others who are developing their own system or workflow: I don't scan anymore than I have to. I scan mostly 35 mm slides and they remain in their original box except during the actual scan, so I don't have the dust problems that others on this list complain about. I don't leave scans on my hard drive any longer than I have to (it's surprising how fast even an 80 gig drive will fill up if you don't purge it often). I transfer files from the hard drive to CD as soon as possible (as protection against a crash and to allow for disc purging) and I make CDs only if I anticipate needing to work with that image again (if I guess wrong, I can always re-scan). I store images in psd format, not tif or jpg, and at their full uncompressed resolution. These files are never stored as sharpened images and Photoshop annotations are added when useful. Each slide and its digital file is give a name that includes the date it was processed, the roll number, and the frame number (for example, "28Mar00 R06 F34"). The date and frame number are already stamped on the slide by the processor and I write the roll number on the slide when I scan it. Note that I use two digit roll and frame numbers (R06, not R6) so that they will sort properly. The date could be written in a different format for better sorting too (000328 for 28Mar00, for example) but that's not necessary for my applications. All images for a given job that I want to "archive" on CD are also copied to a "proof sheet" file using Photoshop to create that file. That file is designed to print on 8.5 x 11 inch paper and each image on it is 2 inches high. I can sometimes get nearly 50 images on one proof sheet because I crop tightly around the model and sometimes even "knockout" the model from the background. The entire proof sheet file is heavily sharpened, even if it messes up the skin tones. Each image on the proof sheet has the roll number and frame number printed next to it and the date and any brief notes, customer name, etc., are printed only once somewhere else on the proof sheet. Every image copied to a CD also has its associated proof sheet copied to the same CD. I print one copy of each proof sheet for my records and sometimes an additional one for the customer. I also print a word document listing the file names for each CD. By the way, creating the proof sheet is the most labor intensive part of the process and the area that could use some software automation. But, for me, the software would have to be optimized to get as many cropped and knocked out images as possible on a single proof sheet. That's something no commercially available program probably does, but I'd be happy to share royalties if someone wanted to write such a probram. The result of my work flow is that I can keep a fairly clean hard drive and I have a hard copy of a proof sheet for every important image. I, or my customer, can use the proof sheet to readily identify and locate a given slide or its CD file by using the file/slide name shown on the proof sheet. Some people might prefer to keep a copy of the proof sheet on their hard drive, but I prefer to purge it and use the hard copy version instead. By the way, unlike others on this list, I don't consider CDs as archival storage due to their relatively high failure rate and prefer to rely on the original slides themselves as the archival storage media. CDs are a convinience, but are not likely to last as long as the original slide.

Blue LED's did not exist as anything other than laboratory curiosities until within the last 5 years. Sure you could have done that 15-20 years ago. Use filters...red, green and blue filters certainly were around 15-20 years ago. LEDs are monochromatic light sources and can't be filtered to another colour. If blue LEDs were not available, outside the lab, as stated above, until 5 years ago, they why were there blue lenses available for LEDS in at least the early 90's if they did nothing? My guess would be that perhaps a conventional red LED (not a laser LED, which by definition is strictly monochromatic) has a wider spectral response than I gave it credit for. You wouldn't be able to get much light by filtering something that is mainly red though. The blue LEDs recently developed have most of their output in the blue part of the spectrum, and are rather better suited for turning into blue laser diodes. I know laser diodes aren't used in film scanners, but the driving force in LED development is for lasers in shorter and shorter wavelengths to allow optical storage of higher and higher capacity.

As I understood stops it was an additional f-stop. I know its confusing, but this is what Kodak says on their web site.. Since you use a lot of the pro version of this film, I have another question. My wife has tried the Elite Chrome 200 on several occasions. Each time she had it pushed (one push, shooting at 400 ASA) the results were variations of red shadows ranging from mildly pink, to downright ridiculous red Dmax. I really think its the same film, the slight variations that I have noticed on occasion may be due to improperly stored film etc... I do expose at 320,640 and 1000 with good results.. you should just be aware that the dynamic range at ASA1000 is very shallow. And, BTW, it does seem that shooting this film at ASA400 with one push is not a good idea, as her images were all underexposed by close to one stop in any shadow areas (almost like it wasn't pushed at all)... She should try it with the meter set at 320, I have never tried it at 400 so really cant say.. the other variable to consider is: was the film developed properly?, sometimes I wonder with the lab I use.. and they have pissed me off on a couple of occasions.

E200 is the professional version of Kodak's new 200 speed color slide films. E200 is manufactured to the more exacting specifications required by professional photographers. E200 also has a specification for push processing, which allows it to be pushed to 3 stops. The consumer film is also designed to a color balance position suitable for consumer storage and usage conditions. E200 does have really fine grain, somewhat at the expense of resolution/sharpness (as compared to the ASA 100 films). Joel W.
