Ok, Pierre, two more minutes.
I did not understand that I should whiten everything, so I tried to match the adjacent colour (Maybe it’s a language problem). Haven't whiten that colour yet, so you can see what I mean.

Decrease Sat and increase Lightness in Hue/Sat, AL layer.
Select the rest and use the same technique.
The adjustment is subjective, but the technique are still fast and precise.

Hi Nancy

I did the same as Frode. Then curves layer to balance the two halves of the shirt.
Desaturated the colour and did a bit of cloning to remove any sign of the two halves.

Red eye tool. As if.

That’ll be 1$ donation to RP.
Colour corrected for free.

Nice work, Ken!
You show us just the way to do it

You did a nice work to, Cassidy!! If you use the combined mask and a new AL, you get the white.

real quick..

1) Create a desat adj layer
2) Copy G channel and set black point to the red area of the shirt... invert so black is now white(this is your selection
3) paint in the desat adj layer with this new selection
4) Group a curve in SCREEN mode over the desat layer and you're done
5) for the anal... use a hue/sat layer to address the red cast on the lower left section of the image... no red, so no cast

Elapsed time: 2.5 minutes

And yes, red does bleed both in photoshop and in the wash

This is brilliant, Cass! I took your image, copied and pasted it to itself at "soft light" and that brought out the wee boys features perfectly.

Thanks all,

Thanks all! I had the same problem, and couldn't quite get the gray out, without blowing it out! It can be soooo frustrating... cuz I know it can be done.

White Shirt

The problem with a color change like this is that for the three different areas of the shirt you have three different highlight/shadow ranges.

I first selected the entire shirt (collar too: it's not white, it's red), applied a hue/saturation adjustment layer, pulling the saturation all the way to the left. That eliminated any color issues.

Two other channel masks allowed me to target the red and grey areas of the shirt with curves that lightened both highlights and shadows to an acceptable range for white and that brought them both into a common range.

Anti-aliased masks being what they are, a seam remained between the two areas. Merge visible to a new layer allowed me to deal with that seam using the healing brush, and also to extend the shape of the material folds upward in a more natural manner.

A final curve, using the original shirt mask boosted contrast slightly, bringing out detail over the entire shirt.

I think it is really hard to change dark colors into white, but this case I d like to do it in LAB mode, so I can handle lightness and color seperately, make selections, use levels to match the lightness. and desatured the colors. use stamp and patch tool to remove the unnatual areas.

Hi Nancy

Thanks for your comments.

“Couldn’t quite get the grey out, without blowing it out!”

I think the only way to leave the detail in is to leave some grey in. Removing the grey is, in effect, removing the detail that makes it look blown out

I had another go at this using the channel mixer. Please let me know what you think. I learn far more from comments like yours. It is very easy when concentrating on one problem to miss another.
