In photoshop, how do you remove yellow tones from an image?

Question

OK - I have to take product shots in a dim warehouse lit with sodium - somethingoranother lights. Most all of the images have a dim, orange-yellow-green cast to them. I can't use a flash due to the high reflectivity of the merchandise so I have to open the camera way up to get as much light in as possible. What is the best way to remove this tint from the photos in photoshop?
THANKS!

If you have yet to take the pictures, and if you're shooting in jpg, simply adjust the white balance setting on your camera. Use a custom white balance if your camera has this feature or try the presets.

If that's not an option, here's a dead easy step-by-step instruction on how to correct the white balance in Photoshop with levels and curves: http://www.adobeevangelists.com/pdfs/photoshop/tipsandtricks/CorrectByNumbers.pdf
I use this procedure myself and it works just fine.
If all of your pictures require the same treatment, just retouch the first picture by hand, then save the levels and curves as your defaults and apply them to the rest of your pictures with the auto button.
And if you need to adjust tons of pictures, save those steps as an action and automatically bulk process the entire folder.

Since I'm a lazy bastard, I currently use the automatic white balance correcter in the Power Retouche plug-in for Photoshop. That does a pretty good job with zilch effort.

Yep, that's film. Also, notice how all the subjects have edges. Nothing is fuzzy or blends into something else. Some of the effect in this photo is due to burning and dodging during enlarging. 1. Open and make a copy of the photo 2. Tweak what you need to tweak 3. Enhance>Adjust Color>Adjust Hue/Saturation and slide the Saturation slider all the way to left to remove the color information. Removing the color using Hue/Saturation leaves the photo in RGB color mode so you can still do things to it. 4. Now, let's try to get the photo to pop: Enhance>Adjust Color>Adjust Color Curves and Enhance>Convert To Black and White can both be used to add to contrast, highlights and shadows. You can also try Enhance>Adjust Lighting>Levels (or a Levels Adjustment Layer) and use the black and white points of the Output section. Try the black, white and midtone points in the Input section of Levels, too. And there's always Enhance>Adjust Lighting>Shadows/Highlights. Try more than one of these to boost the contrast.

Answer 6

Adjust the tint toward the blue end of the spectrum and the yellowish color will fade out.
OR
Select something in the picture that should be white and set it to "white", the other colors in the photo will adjust their tint relative to the white object

Answer 7

For Windows, CS2:

CTRL + B for color balance
CTRL + U for saturation
SHIFT + CTRL + B for auto color -- not always successful but worth a try

Hope this helps.
