Tell people to shoot raw and sell them more flash cards.  More money for you 
and better pictures for them.

That is what I said, you need icc profile provided by the lab for exact device 
that will be used for printing.  So preferred
situation is that printer should not do anything.

If the light is too contrasty for sensor to capture you can make it more flat 
using flash, reflector, diffuser, etc... soft shadows
are more pleasing anyway for my eye.
If you want scene to be contrasty you can easily blow highlights or make 
shadows black in post processing.
If you can't make the light flat, then you have to think about exposure and use 
spot metering and think what you will lose and what
you will keep.

They should just make the sensor smaller, the smaller the sensor the less you

Why would I want somebody changing my pictures ?  I just need icc profile so I

I certainly don't want somebody changing the color balance or anything else

That's right, if you shoot raw and you captured all the info who cares about 
the exposure, you can change exposure during raw
converting process and the result will be identical as if you compensated the 
exposure correctly at the time of shooting.  The
important thing to take care of is not to have blown highlights or shadow go to 
pure black and matrix metering in flat light will
take care of that in most of the cases.  I still would compensate for black or 
white door but for the sake of discussion I don't
think it would make so much difference as you think.

How can you go wrong if you did not lost any information ?  I am talking here 
about evenly lit object.  Ok, if that black door has
small white dots that you don't want to be blown and they are too small for 
matrix metering to take them into account that is
another thing as you are obviously loosing information about them. :)  But 
plain black or white door should not have problems with
that. :)

Re: Understanding exposure? Recommendations?

2005-05-20 Thread David Zaninovic
Thanks for the lesson but I don't need it, that was one of the first things I 
learned.   After that lesson I was running around with
grey card for months in hope I would get better exposures.  Now I know better. 
:)

I am now concentrated on reducing the contrast of the scene I am photographing 
and I don't worry if I get exact exposure.  I worry
if contrast of the scene matches the contrast that the sensor is able to 
capture, it is easy to shift exposure up or down if you
captured all the information there is, who cares if it is a little brighter or 
darker.   Matrix metering is very good if contrast of
the scene can fit on sensor, if it can't fit the picture will not be good 
anyway.  Except if you want to have blown highlights or
shadow without detail because you want to be artistic. :)

I think that shooting in RAW format and looking at histograms corrupted me.

Re: Understanding exposure? Recommendations?

2005-05-19 Thread David Zaninovic
Here is my philosophy.  If the light is even it will be hard to do something 
wrong, matrix metering should take care of exposure
well and will capture all the detail as that is what matrix metering does best, 
it is easy to make corrections in Photoshop using
levels.  If the light is not even, make it even using flash, graduated filter 
or collapsible reflector/diffuser.  If you don't have
any control over the light then you worry about exposure and what part of the 
picture you will lose but there is a good chance that
the picture will not be so good because of too high contrast of the scene you 
are trying to capture.  There are some exclusions to
this but in 99% of cases it works fine for me, especially because I shoot in 
raw format and know how to use shadow/highlight detail
tool in Photoshop. :)

Re: DA-40 on 35mm? was Re: LittleTest:

2005-05-16 Thread David Zaninovic
Who is going to carry all this stuff ?  I don't want to have heavy load on my 
back the whole day.  It is too heavy as it is.

What I have in the bag right now:

*ist D
Pentax 16-45/4 - my "normal" lens
Pentax 70-210/4-5.6 - squirrels and chipmunks
Tamron SP90/2.8 - macro and portraits
Pentax F50/1.7, for bugs, using stacked with Tamron
Set of extension tubes - using with Tamron and F50/1.7 for bugs
AF360FGZ flash - for bugs and to get rid of shadows in daylight
3 sets of batteries just in case.
the rest of the stuff is light.

I will probably replace 70-210 with DA50-200 when it comes out but only if it 
is better optically.  I am trying to have light and
optically great at the same time, I can live with f5.6 in exchange for less 
weight, D has ISO200 minimum so that is much better than
the film I was using before Velvia 50 at 40 and Astia 100 at 80.

I would like to have 400/5.6 in my bag for birds but I think that would be too 
heavy to carry all the time.

Re: reverse mounting lenses

2005-05-11 Thread David Zaninovic
I don't think I would be able to shoot 3x macro of anything that flies. :)  It 
is hard to find where the bug is as it is.
I ordered Vivitar tubes from B&H, passing electrical contacts can only be a 
good thing and I did not notice any problem with P-TTL
at 1/4000 so that is fine with me.  If I move significantly inside 1/4000 the 
whole image will be blurry anyway.  I can easily set
my D to use TTL if I want by setting aperture away from A position on the lens. 
 I also ordered some male to male rings so I don't
have to use duct tape.  I just hope this will be enough extension to get rid of 
the vignetting.

Irony is, I sold my Pentax auto tubes after I got Tamron SP90 1:1 macro.  I did 
not think I would need anything better than that
until I tried to shoot an ant which was 2mm in size and I wanted to see how his 
eyes look magnified.  I was able to get the picture
of the eye but everything else was out of focus because of f2.8 as that was the 
only aperture that did not have vignetting. :)  I
also thought that Tamron SP90 has enough built-in tubes as it is so why add 
more and move the focus inside the lens.  But it looks
like there is another purpose to tubes except moving the focal point closer to 
the lens.

I would like to have P-TTL because of the wireless high speed flash option on

transfer electrical contacts.
It is much easier to shoot bugs handheld with flash set to 1/4000 speed and

2005-05-10 Thread David Zaninovic
How much extension did you had to add to that macro lens ?  You also focused 
the macro as close as possible, right ?  Were you able
to shoot at f11-f22 without vignetting ?  Does the extension that you add have 
more effect than the built-in extension or it is the
same thing ?  Is the rear element on the FA 100/2.8 fixed or it moves depending 
on the focus ?  I see that the built-in extension on
my lens has very little difference in regard to vignetting so I am afraid that 
I would have to add to much extension tubes which
would be unmanageable.  Is there any automatic extension tubes that would pass 
the electrical contacts as well as aperture control
so I can keep P-TTL.

yes, that seems to help but not as much as I would like.  I think that front 
element on the 28/2.8 is just to small.  I will get
F50/1.7 in a few days and will try with that lens.

Tamron is already a 1:1 macro lens so it has its own extension tube which is 
very long.  I noticed that there is not so much
difference if I focus at infinity or as close as possible, there is a 
difference but not more that few f-stops before it starts to
vignette.  So If I add even more extension I don't think it will help much as I 
could end up with ridiculously long tube.  Or adding
extension is something different from what the Tamron is already doing, it is 
possible as rear element on Tamron is fixed and it is
right at the end of the lens.

Strange that it does not make any difference.

think of that. :)



reverse mounting lenses

2005-05-10 Thread David Zaninovic
Is F50/1.7 front element large enough to be reverse mounted on top of Tamron 
SP90/2.8 ?  SMC-M 28/2.8 works only when Tamron is set
to f2.8, beyond that I get vignetting.  Which lens is recommended for reverse 
mounting ?

I see that it helps if I focus the Tamron as close as possible but not by much. 
 Is it good or bad the fact that Tamron has deeply
recessed front element ?

Thank you !

Re: Digital profligacy

2005-05-06 Thread David Zaninovic
I feel that opposite is true, there are more people taking high quality 
pictures now than ever.  Learning curve with digital is much
faster because there is no penalty for taking more pictures.  I am talking 
about people who actually want to learn photography.

People who take snapshots are at the mercy of auto everything in camera as they 
were before with film when processing in Wal-Mart or
similar store which does not even look at the pictures.   If they are used to 
processing in pro lab and want better pictures I am
sure these same labs would be happy to take care of their jpg-s and make them 
look right, it would be best if these people would
shoot raw and let pro labs do the processing like they did with film.  Maybe 
that is what you are talking about ?

Maybe you can find a lab that will accept your raw images from camera and 
do the work for you like with film.  You will still
save a lot of money because you don't need to buy film.  I use camera for my 
own fun so doing my own processing in Photoshop is a
joy and actually improves the experience, I don't want somebody else doing it

Maybe his cost of materials and effort for each copy is greater than with 
software.  With software people already have the trial
installed they just need the key to activate it so materials for each copy are 
much cheaper for them.  They could charge $500 for

It is not like you will wake up one day and everything will be obsolete you 
will have enough time to prepare for a change and adapt.
If they stop making compactflash cards you can use SD to compactflash adapter.  
 If they stop making SD cards there will be some new
adapter, etc.  If they stop supporting D in raw converters you will know that 
as soon as you pick up a new converter and see that D
support has been dropped, you can then convert all your RAW files to something 
like DNG and continue.  If they stop making CD and
DVD readers you will know that and you can copy all the data to brand new 5TB 
hard drive which you got for $50 after rebate.  I am
more afraid that my D will stop working after the warranty expires because of 
all the electronics inside and that it will be too

DNG vs PEF

2005-03-18 Thread David Zaninovic
So what is the final verdict on DNG vs PEF ?  What do I lose by converting PEF 
to DNG ?  Do I lose any picture information or just
metadata, like which lens was used and other things I don't really need.  I 
need size reduction from 13MB to 5MB, that is a huge
difference.  If I have to keep PEF-s then there is no reason to use DNG.

Is that the same as Nikon AF Nikkor 70-300mm f/4-5.6D ED, it is also 13

It is my impression that I started seeing dust when I started taking macro

Do you use polarizer over the flash for that ?



Re: CCD cleaning

2005-03-10 Thread David Zaninovic
I know that the effective aperture reduces with the amount of the 
extension.  This smaller effective aperture increases DOF and
reduces the light, so why wouldn't it also increase the visibility of dust like 
real aperture decrease would as it is effectively
the same thing.

DISCLAIMER: Of course I could be completely wrong as I am playing with this 
photography stuff for only a year and few months.

polarizer

2005-03-10 Thread David Zaninovic
I just got a polarizer and I am trying to figure out what can I use it for.  I 
noticed that it darkens the sky, steals a lot of
light, removes reflections from glass, water and some shiny objects like cars, 
from some objects even indoors under neon light,
darkens the LCD to black. :)Can I use it with flash in some usable way ?  
What If I put a second polarizer over the flash ?
Does it affect contrast ?  How about snow ?  I did not try to shoot any 
pictures yet, I am just trying it first without the camera
to see what it can do.



Re: CCD cleaning

2005-03-10 Thread David Zaninovic
Focusing distance changes the aperture on macro lens as you add more extension 
you are effectively making the aperture smaller.
That is how I understand it.

It was quite easy, I needed 4 pec-pads to remove 99% of the dust.  I still have 
some left, I think it is stuck so it will need more
cleanings to go away.  It is probably stuck because of me using the compressed

eclipse + pec pads for CCD cleaning

2005-03-03 Thread David Zaninovic
I noticed that my macro shots have many dust particles visible in pictures.  
That is not a big problem right now as there are no
insects anyway but I have to prepare for the spring.  Canned air do not work 
for extra small dust and I have hundreds of those.

I ordered some eclipse, pec pads and some kind of rubber wand and I hope I will 
not destroy my CCD. :)  I don't like the idea of a
static brush, too expensive and I don't think it will work for stuck dust so I 
will have to use eclipse anyway.  Better to learn how
to use it from the start then.  Maybe if the static brush were around $30 I 
would buy it as an addition to my cleaning kit but at
more than $100 I don't think it is the right price.

Thank you !  I will try these tips and will do some more investigation on raw 
vs jpg highlight/shadow detail, there might be hope
afterall. :)

than it appears in the photo. I think a jpeg would have blown out highlights 
and lost shadow detail if it was exposed the same as
this shot. The key to RAW is in how you convert it. I have a book devoted to 
the RAW converter. I don't have it here with me at
work, but I can supply the name of it later if anyone is interested. The author 
goes to great lengths in explaining how a shot can
be dialed in using exposure, shadow, brightness and contrast. What it amounts 
to is that you expose to preserve any highlights that
are critical. Then when processing the RAW image, you adjust the exposure 
slider so that all your critical highlights are in range.
If  you hold down the alt/option key while moving the slider, the highlights 
that are out of range will be revealed as bright areas
against black. Then you adjust for shadow. Again, if you hold down the alt/o!

After that, you adjust your midtone levels with the brightness control. Adding 
brightness in the raw converter won't affect the
highlights. It's  not the same as brightness in PhotoShop. Finally, you adjust 
contrast. This will pull the histogram toward the
ends of the scale of push them toward the middle. Again, it's different than 
the contrast control in PhotoShop. It's more like
tweaking the rgb curve. Of course there are other factors to consider such as 
color temperture, hue, sharpness, etc. But these don't
affect shadow or highlight rendition. Best of all, the RAW converter is a lot 
of fun. It's a great tool for the digital
photographer.

Good highlight and shadow detail, I would be happy with those results.   
But this was not done at most contrasty time of the
day, right ?   Do you think that jpg would remove some of the hightlight detail 
or it makes a difference only in shadows ?  You have
some realy nice pictures on photo.net by the way.

is no comparison between jpeg and RAW. It's like night and day. Here's a shot I 
did yesterday to test the 28/3.5 for another member.
It includes snow in bright sun and heavy shadow under a bench. You'll find 
detail in the snow and plenty of information in the
sahdow. It was shot in RAW, and processed in PSCS. A bit of additional 
adjustment was done with the Shadow/Highlight tool in PS
after conversion. There isn't a slide film in the world that can give you that

opinion. Others may differ. Here's the shot, which

Shooting jpegs limits some shadow detail but that "detail" is mostly noise in 
my opinion.

This digital exposure latitude looks more like Velvia 50 to me.  That is fine 
for controlled shooting but for noon snapshots it is
terrible, I hope that AF360 can control this contrast at least for people 
snapshots.

I would be more happy if they worked on more exposure latitude than more 
megapixels.  D has much less exposure latitude than Astia
100F.  I can't take any pictures at noon like I could with Astia. :)  Astia was 
great, but digital wins in every other aspect except
exposure latitude for me.  Maybe I should try using my AF360 set on contrast 
control, does that help ?

Re: 4GB Microdrive Hitachi 3K4

2005-02-18 Thread David Zaninovic
I ordered Kingston standard 1GB for $50, I figured out that I don't want to 
have more than 1GB in one card as that is around 78
raw exposures.  I don't want to lose more than that if it dies.  I also checked 
the read speed of that card and it is not that bad,
better than sandisk standard ones.  I am shooting jpg now as I don't have the 
space but I want to move to raw, it must be better, at
least it is not losing any data. :)
