Color problems

Hi

I'am David from Portugal, 3d Artist and work as photographer to.

At moment i have a big problem hope to get some help from here.


I shoot with a Canon 40D in RGB.
I have my monitor calibrated with X-Rite.
Use the ICC profile in CS4.

My settings:

Working Spaces

RGB: (Profile from x-rite)
CMYK : U.S Web Coated (sowp) v2
Gray: Gray gamma 2.2
Spot: Dot Gain 15%


Color Management Policies

RGB : Convert to wronking RGB
CMYK:Preserv Embedded Profiles
Gray: COnvert to wronking Gray



Now , my problem is: i finish my edit , mt photo look's fine, but when i save it look darker and more Yellow.

Any suggestion?

Thanks

David

Not sure what you meant here. "ICC profile" is a generic term... you'd need to reference a specific ICC profile.... then explain what you mean by "use in CS4".

This is a problem. You should not be using your monitor profile as your working color space. You should be using a standard profile such as AdobeRGB, sRG, ProPhotoRGB.... preferably AdobeRGB, as it is more popular amongst photographers.

(Note: since you do a lot of 3D art work, you may need to work in one space for 3D art, another for photography. The space you work in is generally whatever is most popular in your industry. Your choice of a working color space just helps you produce work that would be consistent with your peers when viewed in a color managed application.)

Simply stated, the monitor profile is designed to add/subtract a little from color values stored within an image so that they will look correct when displayed on the screen. It compensates for problems with the monitor. This is designed to take place on your PC only, and never be embedded into the edited image.

Again, this is a problem since your working space is set wrong. It will result in a double-conversion of your colors.... once when imported, then again when sending to the screen. This will make is virtually impossible to get correct colors in your final output.

Once you correct your working space, you should be able to leave this as is.

Re: Color problems

TommyO, Thanks for your reply, now i understand i think....

So i must use AdobeRGB as my working color space, and at the end convert and save as Srgb for web for exemple.

Last question: When saving, is prefered to Embed color Profile or not?

"Use the ICC profile in CS4" means that i set the iCC profile generated by X-Rite in CS4 as my working color space. ( wrong now i know...)

Thanks again....user error...like always

Re: Color problems

Right colors only in color aware applications + image with profile...
So, good colors only in Photoshop, Bridge, Fast Picture Viewer.
Faststone more or less less less...
Acdsee good but not perfect...

Re: Color problems

Pictus, sei que vais entender, sim isso é certo...apesar de ter o monitor calibrado o icc profile apenas funciona em aplicações com gestão de perfil de cor , mesmo browsers como firefox não funciona , por momentos fiquei assustado o trabalho é para um catálogo de moda...não posso falhar de forma alguma...
Abraço

David

Re: Color problems

David,
You are correct. Color managed applications should not have the problem. Unfortunately, Windows' viewer is not color managed.

If you are converting to sRGB prior to saving for the web, you may consider the previous suggestion... working in sRGB when doing your 3D graphic work. There is really no reason to work in one color space when your eventual target is another color space. Doing so will simply cause you to go through the proof-modify process too many times in the end.... just more time spent doing unnecessary tasks. There is nothing wrong with working in the sRGB color space when your work requires it. Many professionals do so. AdobeRGB is simply more common among photographers and their work environment.

Embedding the profile has two purposes. One, as a way of informing the recipient of what your intent was. The embedded profile gives them confidence it was saved correctly, and in what color space you intend for it to be viewed. Two, it provides a consistent means for their color managed application to convert it to a different color space if needed. The receiving application can convert it properly when the profile is embedded. If not embedded, it must guess.
