Does anyone know of a way to create an image solely in photoshop then load it onto a flash card for use as a custom white balance? I have a digital rebel and it doesnt see any of my attempts. I have even tried saving over files from the camera. Is this possible?

why would you want to this?
it won't be true to the actual light in a scene...

you caould take a picture of the image created in photoshop, and set that to a custom white balance.

First of all I want to experiment. Are the auto settings or settings for shade, sun, etc. on digi-cams true to light?

I was thinking that a person could use exact swatches in photoshop with adobe RGB set as the color profile to create a sort of digital warm card or something similar. Wouldnt it be nice to be able to load a small jpg file onto your compact flash card to be able to set a custom white balance? Maybe it could be useed in a studio environment or where you may want an alternative to duotones etc.

You don't need to make anything to create a custom white balance but a true piece of white paper. You are setting your camera to tell what's white in the environment that you are shooting...normally (indoors) the whites seem to look yellowish, so take a picture of a pure white piece of paper, or prefferably a white card available at RITZ for $5.00, and click MENU, custom white balance. Select the image and your rebel will import the information directly from the center of that image. Now hit your WB button (also the down arror) and use the scroll dial to select the custom WB icon and you're set.

If you shot something that wasn't completely white in the first place, you'd probably end up with something a lot worse than what auto would do anyway.

If you're that concerned, it would be best to shoot in RAW and set the white balance later.

hrmm...after re-reading your post, I don't know what you're shooting for...but if you want to experiment with white balance, why not just shoot in RAW and then adjust it manually yourself to get all the different variations -- that way you can have one JPG that is perfect white balance and one that will give you the effect that you're looking for?
