Yes I know I left the contrast low but I didn’t want to burn out her forehead. I didn’t do that unclipping thing.
I should have done a bit of painting on her hair but I tried to do it without any

Replacing a complete channel is a bit drastic and I’ve just had a play with the channel mixer and I can virtually repair the channel. That’s one for the memory Bank. Thanks.
you're welcome.

i'm a bit of a novice yet, so that tip prolly comes through me from flora and i've certainly heard more than once around here that there's always more than one way to do things in photoshop. so, whatever works!

Ken,

One question.
I have posted my picture (which I am fairly happy with) but I had several goes at this. If I repair the picture in CMYK (replacing the damaged cyan channel with the Yellow) then her blouse comes out Pink But if I do it in RGB and repair the damaged Blue channel with Green then her blouse is Yellow. Why the bid difference? And how do you know what is correct?
Duv works in CMYK but got the blouse orange.
What I know about RGB/CMYK colour modes is that:

*Monitors work with RGB which has a wider Gamut and Gamma.

*Printers work with CMYK which is more 'limited' in Gamut and Gamma.

*RGB is Additive.

*CMYK is Subtractive.

From PS help file:

Use the CMYK mode when preparing an image to be printed using process colors. Converting an RGB image into CMYK creates a color separation. If you start with an RGB image, it’s best to edit first in RGB and then convert to CMYK at the end of your process. In RGB mode, you can use the Proof Setup commands to simulate the effects of a CMYK conversion without changing the actual image data. You can also use CMYK mode to work directly with CMYK images scanned or imported from high-end systems.

... and those might be the reasons for the big difference you get when tweaking Channels in these two colour modes ... But my knowledge in this field is very limited ....

I always check and often use these differences at the very beginning of a restoration... but then I always go back to RGB and do all my work there because, beside feeling more comfortable with it, RGB is the only mode where all filters and adjustments are available... so, my experience in working with CMYK is practically nil ....

For your restoration .. superb skin tone and colour ...
... otherwise, in my opinion, a bit too much red ... particularly in her hair... but there is some red in her eyes and teeth also .... from the original we know that her blouse is yellow .... I agree that the original had a strong cyan cast ... but once removed the cast in RGB, the blouse remained yellow ...

Change the colour of the blouse or any colour in the picture if you wish ... but I wouldn't accept and keep the 'wrong' colour simply because some 'tweaking' got me there... In my attachment the new position and the result I got after only removing the Cyan cast with the Curves' Set Grey Point. (since my previous description I changed the point's position).

As usual, my 'instructions' are simply descriptions of what I did ... and not of what should be done ... as Craig said " there's always more than one way to do things in photoshop. so, whatever works!" ... or whatever you feel comfortable with.

Thanks


Thanks to all who lavished me with compliments. I've said it before but I am truly humbled by most of the the folks here. I play with Photoshop because it's addictive and I simply can't help myself; BUT I am a complete novice. Especially compared to some of the whizzes and major talents that float around this site. I thought for a little while several years ago of making this a profression, but I realized that I don't have the knowledge base to be of the quality that I would want to provide. So I will just continue to play.

One question for those that are great with hair...how did/do you make a mask for the hair in the lower left corner of the picture where the background isn't all that far off from the hair in tone. That was the one thing I was unhappy with in my finished version, but I didn't feel like I had time to figure it out.

Hi Elle!

Thanks for your comments. More often than not, when you have extreme color casts, restoring is a bit of a compromise. To me, the important area is the skin tone for portraits. If you can get a yellow shirt as well..good on ya! I'm impressed that you "saw" the skin tones. When you work by the numbers and it turns out visually as well, it's quite gratifying. By the way, have you been busy? Haven't seen quite as many posts from you recently!

Cheers
Dave

flora,

i'm not familiar with the term 'Gamut' as you used it here:
Quote:
*Monitors work with RGB which has a wider Gamut and Gamma.

*Printers work with CMYK which is more 'limited' in Gamut and Gamma.
could you explain this term as it's used here, please or direct me to somewhere that does?

Craig

I agree Dave, but to me hair and eyes colours are just as important in portraits ... I don't care if the shirt is yellow or pink as long as I can get it as close as possible to what the original colour was or seems to have been ... and to me this is important as well ... That's the point I was trying to make insisting on the yellow blouse .... nothing more to it ....

Craig,

from Photoshop's help file:

Quote:
A gamut is the range of colors that a color system can display or print.

A color that can be displayed in RGB may be out of gamut, and therefore unprintable, for your CMYK setting.
(this happens because RGB has a wider 'gamut' than CMYK)

Quote:
Photoshop automatically brings all colors into gamut when you convert an RGB image to CMYK. But you might want to identify the out-of-gamut colors in an image or correct them manually before converting to CMYK.
And another description:

Quote:
RGB Monitors and CMYK output files:
Both the Gamut and Gamma of a monitor exceed that of the printed page. That is to say that a monitor can display more colors and a broader range of tones than it is possible to print with ink on paper.

When a file is converted from RGB to CMYK these colors must be adjusted to be within the range of printable colors and the Black channel must be created.

These complex transformations must be done in a manner that precisely matches the profile of the output device. And once you have separated out the black and limited the gamut by converting to CMYK you cannot convert back to RGB without seriously degrading the color and quality of the image.
Hope this helps ...

flora,

thank you

that actually helps possibly explain a problem i was having with my printer. normally, the printer prints almost anything in true color and near photo quality, but if the print has a LOT of blue, particularly a lot of hues of blue, the printer cant seem to handle it and the blues come out quite a bit darker with much poorer color separation and identification. this could be the reason why.

Here is my take on the picture

It is unfortunate when you loose a loved one at an early age. After I edited the picture irealized it was originally posted more than two years ago.

Flora, I absolutely agree with you but in the absence of information..her eyes are hazel, green, blue or brown and her hair is brown, reddish brown, black, blue black, it becomes rather guesswork. However, with skintone, if you have 35% Cyan in the skin, I'm not sure that is plausible for a Caucasian, even though some might think that is natural. I think you might agree though that for portraiture, the logical events might be skin, then eyes, hair and then clothes, background, etc. Of course it all has to blend in and make sense as a whole. For example in my first posting the coloring of the hair on top probably needs adjusting. Anyhow, it was mentioned that the girl has hazel eyes. I have hazel eyes and haven't a clue what the color is. It's got grey, green, blue and rimmed with yellow. How the heck do you color that in?? You bring up good points as usual!

Cheers
Dave

Flora decided

This sentence was meant to be humorous. I.e. I thought there was something in the picture but I was wrong.
I thought about this and my wife tells me it could make someone sound overbearing or dictatorial if it was taken literally. If that’s the way you read it then I apologise.

Maybe deduced or determined would have been a better choice of words

Verb Decide to make a decision

Italian
Italiano (Italian)
decidere, giudicare
In Italian it seems to mean ‘to judge’ as well. But is does not mean this in English.

You speak three languages. I only speak 2, English and Rubbish

I hope everyone can weigh in with an opinion on my 3rd and hopefully last effort. All I did was global curves adjustments and to be honest, I was using RGB, CMYK and LAB. What I was trying to achieve was reasonable skin tone and hazel eyes. I have hazel eyes myself and I "think" I got the color right but not sure. Is the skin tone reasonable? Any thoughts?

Cheers
Dave

Hi Dave, I get a slight red tinge on my monitor. This is based on observation only, haven't opened it in PS and checked the numbers yet. Most visible in the whites of the girls eyes. Mind, its after Midnight here, so could be my weary bloodshot eyes.

OK, looked at the numbers, it's not my eyes.

On the girl's right eye (as we look at her) the white area to left of her iris gives (R235,G202,B201).

Hi Gary. Thanks for responding. I actually get slightly higher red readings. What do you think more reasonable values should be? Also, I'm not sure that strictly global corrections can get you there. I think fine tuning of specific areas are necessary for this image. Hope you'll also opine on the iris and skin color.

Cheers
Dave
