OK, so I've got this assignment where I have to scan in a daylight-balanced color slide then manually correct the color temperature in photoshop. My prof is saying this takes a long time and on top of being on deadline with only about an hour to work, i was just trying to see if anybody has had experience with this situation. word
ugh i suck at color correcting anything besides snow
google is your friend
Drop the menu under 'Image' on the PS toolbar and get all the color adjustments.
It's a start.
Use a curves adjustment layer. As a start, look for things in the photo that are a neutral tone (white, gray, black) and make their R, G, & B values all equal.
edit: definitely Tech Talk Biatch.
go into image, adjustments, auto color balence, if that isn't enough go to color balence and bump up the cyan and blue in all the ranges (shadows, midtones, and highlights)
There is a program called Adobe Lightroom? It is basically photoshop for photographers. It allows you to adjust tone curves, color curves, exposure, filters, and so on. Great program, fairly small learning curve, I use it on my digi photos all the time.
The color temp should be adjustable with with the white balance adjustment. However I am not sure if you can do that with a scan. I know you can with a RAW image.
Ligthroom and even Picasa (I think) will allow you to adjust the colortemp of any picture format they can read (eg. jpegs, tiffs and so on).Quote:

And Tech Talk, BIATCH:FIREdevil.
i *think* the problem with flourescents if more than color temp... if you look at the spectral output of a flourescent there are huge gaps... its not so simple as correcting for tungsten lighting... then again i had an FL-B filter for when i was shooting slides under flourescents so i never corrected in PS
apologies for the misplacement of this thread. thought tech talk was more for gear.
this has worked well for me.
