removing colour casts simply

[dbax]

Hi all,
Just had to remove a yellow cast from a photo. I find this method easier than using the colour balance, and it seems to work on any colour.

In CS3 or any version(that has layers and blending modes) as far as I know.

Duplicate layer
Apply Blur>Average
Change blending mode to soft light.

EDIT- CORRECT STEP ARE: (see Dbax post below - **RICK**)
Duplicate layer
Apply Blur>Average
Ivert( image>adjustments>invert)
Change blending mode to soft light.

simple as that,can be made into an action so its a one click fix

Thought I'd share it and ask for feed back

thanks - i always check the hints and tips......

I don't want to sound pedantic, but I couldn't understand why it would work so I tried it - and indeed, it didn't remove any color cast. Soft light blending just increase tonal range AFAIK - whatever is dark in the image gets darker and whatever is light gets lighter. It's a solution to repair washed out foto's but if I understand correctly it doesn't change color.

Can you show us an example of where it works?

Hi Jev,
damit of cause it works if I'd included all the steps, some body kick me please

Duplicate layer

If one of the mods is able to correct my mistake I'd appreciate it, don't mean to give incorrect information. Sorry
Heres the image I corrected yesterday

Consider yourself kicked

Works a treat much easier than trying to find a 'colour neutral' spot to use.

Have a couple on me

Cheers David

I'm still scratching my head over this one. Where's the downside? There has to be a downside doesn't there? Otherwise we'd all have been doing this long since. Still puzzled.

I see the results, but still can't quite grasp the concept

Just add some blue and hey presto ??

Got a heap of old slides that have been scanned that could do with this

[pommie]

I have a few images with a heavy blue tint (wrong temp setting when taken) and this worked on them
So it seems to be the inverting that does the trick.
As I shoot in raw the colour temp can be altered when converting, but still a nice trick to keep up my sleeve for when a colour cast is created during processing or its a light tint and I don't notice it while converting

I've been using this for almost 2 years now and had very few that it hasn't worked for. Don't know how or why but its a gem to have as a back up

My attempt to do this (in CS2) seemed to work, though at the expense of noticeable lightning and desaturation of the image. Perhaps I'm cocking it up? I have unlimited capability to do that.

Rich, anyone who can use "curves" and "easiest" in the same sentence needs to get out more!

Most people struggle with the Photoshop curves control for a long, long time, and many never master it. (I certainly wouldn't claim to be a master of it myself, far from it.) Most people, unless I miss my guess, are prepared to go a long way out of their way to avoid the curves command. As witnesses, call the many, many "how to use curves" tutorials out there, the large number of plug-ins that provide a more intuitive interface to achieve the same things, and even (late to the party, but better late than never) Adobe themselves, who have substituted a much more usable and apparently popular control in Lightroom, which has been a great success.

(Reminder to self: have a look at CS4 in case they have ported some of the Lightroom functionality over to Photoshop.)

(Sorry, I'm off-topic.)

(As usual.)

This seems to work quite well. Thank you mate
