removing color cast

johnm160 · #1 01-13-2008, 06:42 PM

Hi gang,

I have been lurking here for quite a while now learning tips and tricks. I have an image now that I thought was going to be easy to fix, but I just can't do it. It has a sepia type color cast that I cannot get rid of, my scanner can get rid of it but it messes up other portions if the image in doing so, besides that cheating.

What I also find intresting is that the color cast is not as bad if I scan it into photoshop instead of just scanning it to the desktop with the scanner software.

Could someone please help me out and explain how to correct this?

Thanks

Uhhh, I took a quick peak at your channels and saw your red channel was blown out, tried playing with selective color but it wasn't doing a very good job - so I toyed with the curves on the red channel (Image > Adjustments > Curves... "...(new method for me)

Pretty good results, in comparison to my best efforts with selective color... after that played with red some more in selective color (Image > Adjustments > Selective Color).

Maybe just a touch yellow still - but I can't tell on account of my poorly configured monitor! >.<

Hi there

I did the same Stephen... played and played... ended up adding color here and there

Thanks guys, Curves is still a bit tough for me to figure out.

This is the best I have been able to do....only worked on the color at this point

The second pic here is what the scanner was able to do on it's own.

Ticks me off that the scanner did a better job then me.

First I adjusted the levels,
Then the white point in curves (the walk way 222, 255, 255),
and at the end I have (selectively) toned down the saturation a bit

Ok this is my first try at this stuff....

I adjusted the levels a little, and then made a curves adjustment layer to mess with a few colors.

Then tweaked the color balance and contrast a bit.

Finally I just cloned the obvious damaged areas for a quick fix.

I don't know how to link the photo like you guys though...

I adjusted the eye dropper readings on the face using the 5-4-3 rule to start. Then I corrected the white, gray and black points to correct the overall tone without blowing out the highlights or darkest point so it would be printable. No the best job but the numbers look right.

Hmmmm, All I did was Levels! On the R, G, B, separately as described at the beginning of this tutorial "Restoring an old photograph" by cameraken:
http://retouchpro.com/tutorials/?m=show&id=255

Then decided to crop and play..
Cropped, Levels, Masked pretty lady, Multiplied 4 times (to darken background), darkened highlights in background, Cleaned up some green spots on lady and lots of dust stuff.
A large version of the crop is here:

Hi Joeven...I'm curios about waht you mean by this rule. Cld u explain further pls? Thanks

Hi John,

I took the easy road

Levels adjustment layer, bring the individual channels into the majority of the information.

New Layer>Fill>R 203 ... G 150 .... B 115 ... Image>adjustments>invert. Take the blend mode of the layer to colour and drop the opacity to about 20%. Hue/Sat adjustment layer, boost the sat of the image to what you like.

Go on from there to do any more fixing, levels etc.,

I used Swampy's method of copy layer, filter->blur->average and then invert and set to overlay mode 3 times, then a final levels adjustment

Hi Liz. The 5-4-3 rule is the ratio of red to green to blue in the skin tones. Here's a link that will explain it better. I hope this helps

I used color balance and variations to start, then a lot of other plays to the point where I lost tract but here's the result.

Kraellin · #15 01-14-2008, 10:57 PM

first thing for me was to brighten things up a bit. no contrast, just brighten. then adjust the colors, and then a bit of enhancing and cleanup.

so,

1. brighten/contrast adjustment layer 50/0

2. color balance adjustment layer, mostly to take the reds down and add a bit of blue on the shadows, midtones and highlights.

3. a tiny bit of clarify to bring some better contrast, but just a tiny bit. +2

4. usm at 2/100/5 for a bit of sharpness.

5. a bit of clone to take out the tear/fold mark, the bad upper right corner and a bit of speck/dust here and there throughout.

i also like the idea of cropping here, though i didnt do it, since i wanted to show all work done.
