I've noticed that my colors are off between DPP and PS7. This is probably a color managment issue which is yet another thing I'm struggling to learn. Anyway, I've got everything(camera,DPP, PS7) set to Adobe RGB. After I convert, save, and open my image in PS7 the tones are a bit differnt, especially the skin tones are a bit pinker, whereas in DPP they're more neutral. It's nothing major, but just curious whats happening here???

Here's a picture where her skin is pinker than I'd like, it's much more neutral in DPP.
Also, I have this blueish color cast esp in the whites. I tried to adjust the WB by manually selecting a white part of the image. I also tried selecting shade since it was shot in the shade, but both methods resulted in a much yellower image. I'd really appreciate any input as to where I might be going wrong?

it looks ok on my monitor, I would however add some saturation and USM, may be reduce a little bit blue (just a little), other then that look good to me

some programs have an automatic white balance i think rawshooter does if you shoot in raw but i zapped this w/the software that came with my hp printer

Thanks. That did get rid of the blue. Does anyone know why the colors aren't consistant between DPP and PS7 when they're both set to Adobe RGB? BTW hows the exposure, dark?

I keep trying but not really satisfied w/ it. Got out my Scott Kelby book and selected my white and black points. Adjusted the curve to adj the midpoints. Added a bit of blue and a touch of red. Got rid of the blue, but color still seems a bit strange..yellow...ugh. This color correction business is a pain. Seems I always have this problem shooting in the shade.

You must have shot it RAW, transferred it to the computer, and then used a RAW converter. When you did, which light source did you select?

Hi Bob! You are correct, that's what I did. However, I'm not sure what you mean by which light source did I select??? I'm still kind of a newbie... There's a drop-down menu in the white balance section where it says daylight, shade, cloudy, etc. Is this what you're referring to? Normally I select auto WB. I tried selecting shade because that's where we were and it turned yellow. I tried daylight that was a little better. I just want to try to eliminate the blue cast in the whites without turning her yellow. I tried
selecting the black and white point in PS, and although I did remove the blue cast, I managed to introduce a yellow one.

Also, any idea why the colors aren't consistant between DPP and PS7 when they're both set to Adobe RGB? It actually looks worse in PS. The skin tones are more neutral in DPP.

For me RSE, capture one, and DPP did not produce colours that matched up when opened in CS2. They all looked different. It didn't matter if I saved as srgb or argb. I started using the adobe raw converter and that kept the color consistant.

Are you under Windows or Mac?

Check this thread. (http://photography-on-the.net/forum/showthread.php?t=86654)

It may help if you are under Windows.

Adobe Raw Converter is within CS2, correct? Hopefully I will be able to upgrade soon, but w/ buying the 20D and the accessories and a couple plug-ins, etc. I have to chill out for a bit. I actually liked the colors in DPP better-more neutral..oh well...

I use a Mac.

Hi InskiP,

In order to display well on the Internet, the file has to be in the sRGB color space. Here's why:

And here's why things are blue in the shade:

And the color shift problem is nasty on the Mac. Here's the deal:

Those oughta keep you off the streets and out of trouble for awhile. I hope they help!

Thanks,
Chris

Thanks for the links, I'll check it out... :D

Does anyone else feel like they spend more time reading than actually working??

Why didn't I take up knitting..:lol:

Okay, the numbers in this article are really confusing me. It says that there is a blue color cast yet blue has the lowest number of all the channels, wouldn't it be the highest???

AWB seems to give me a blue color cast w/my 20D. So, to avoid this problem in the future, it sounds like I should make a custom WB using a piece of white paper. Now is this a one-time thing, or do you create a custom WB before each shoot for those particular lighting conditions?

As you have seen, AWB sucks big time! See this for more info & why you should use Custom (almost) every time that you have the chance to. Even under ideal conditions (studio) AWB isn't even close. Problem in the shade, is the light filters through the leaves, blue sky may be a factor, & a nearby building may bounce colored light in, too.

Inskip,
You can use the eyedropper tool to do a custom white balance "after the fact" if there is something white in the image that is not blown out (at least DPP can, I hope other RAW converters have a similar feature). If the collar of her dress is white, try using this method with a shaded part of her left collar. You can instantly adjust all the images shot in the same light with just a few clicks.

I tried the eyedropper trick on the white of her collar but it turned her yellow-it's like I'm either stuck w/ a blue or yellow image. I'm not all that experienced w/ color correction..I keep playing w/ it. I actually adjusted the levels and then applied auto color and auto contrast and it looked better than anything I tried to do manually, which ususally isn't the case. I may just go that route and be done w/ it.

Thanks for the WB link, I'll go over it. Should I make a custom WB for each shoot? I need to be able to shoot in the shade esp when it's blazing sun out. I guess I need to make sure the building is a neutral color(which it was). Any other guidelines for shooting in the shade.

Should I make a custom WB for each shoot?Yes, if you want better results than you can get with the preset options. The color temperature of sunshine changes throughout the day.

Should I make a custom WB for each shoot? Only if you want a neutral result. I'd use a Cloudy preset for candle light or sunsets to keep the warm colors.
