Join Jan Kabili for an in-depth discussion in this video Removing a color cast, part of Photoshop CS4 Essential Training.
Sometimes an image has an overall colorcast like the one that you see here.…There are lots of ways to correct a colorcast, some more complicated than others.…In this movie I'd like to show you a few quick ways to try to eliminate a…colorcast in a photo.…None of these are guaranteed and they don't always work on all images but…they're certainly worth a try.…The first one is the Auto Color command.…I'm going to go up to the Image menu at the top of the screen and there I see 3…Auto commands: Auto Tone, Auto Contrast and Auto Color.…
Auto Color is the one to try to remove a colorcast.…I'll select it, and that is the result on this particular image.…So that you can compare this to the original, I'll press Command+Z on a Mac or Ctrl+Z on a PC.…There's the original and I'll press that shortcut again to show you the current…version, quite a bit better.…Now there is more to do to this image for sure, but at least I've removed that…glaring yellow cast.…Let me undo that again to talk about a completely different method, and that is…

Q: How can artwork be transferred from Photoshop CS4 to Illustrator CS4 without the background?
A: Save the image in Photoshop’s native PSD format. The background in Photoshop must be transparent, meaning there should be no background layer. (To remove a background layer, move your artwork to a separate layer by selecting and copying the content, minus the background, to a new layer, and then delete the background layer. A checkboard pattern behind your image indicates transparent pixels.)
Q: How do I retouch an image I have of an old photograph I scanned?
A: There are a few courses that address image restoration. Check out the Photoshop CS4 Portrait Retouching Essential Training course, and for problems dealing specifically with old photographs, watch the Restoration movies in chapter 15 of the Enhancing Digital Photography with Photoshop CS2. Additionally, learn how to research and date photos with our Growing and Sharing Your Family Tree course.
Q: A client has asked for artwork to be delivered as JPEGs or BMP files in 16-bit format. In Photoshop CS4, there does not appear to be an option to save an image as a 16-bit JPEG. Is there a way to save JPEG files as 16-bit in Photoshop?
A: Unfortunately, JPEGs cannot be saved in 16 bit. JPEGs, by nature, are 8-bit. So if you open a high-bit image into Photoshop CS4, you will see no option in any of the save dialog boxes to save the file as a JPEG. You would first have to convert the image to 8 bit (by choosing Image > Mode > 8 bits/channel) and then save it as an 8-bit JPEG. If you open a high-bit image into Photoshop CS5, you will see the option to save it as a JPEG in the Save, Save As, and Save for Web dialog boxes. But the JPEG will not be saved as 16-bit. Instead, Photoshop will downsample it to 8-bit for you before saving it as JPEG.
