View Full Version : color replacement Nanls 09-16-2005, 04:23 PM What is the easiest way to change the boys shirt all to the same color as his collar (whit)? If you use an adjustment layer.... please elaborate. I tried the redeye tool, and it just wasn't realistic enough.
thanks,
~Nancy~ Kraellin 09-16-2005, 09:06 PM right off hand i would think color balance, channel mixer, curves, a mask and desaturate it, the color replacement tool in Paint Shop Pro, the 'as target' brush in psp, but the fill brush might be the easiest.
Craig Nanls 09-17-2005, 01:12 AM None of it is working for me! :cry: philbach 09-17-2005, 04:00 AM It did seem hard to change the shirt color to the color of the collar. The collar does have some red in it and red tended to bleed out from the edges some. I selected the red and copied that to a separate layer and locked the transparent pixels in that layer. I made a pattern from the collar and filled the shirt layer with that pattern and then blurred that layer some. Caitlin 09-17-2005, 04:17 AM Looks good Phil! adong 09-17-2005, 05:15 AM changes red hereafter change diagram layer mode as the " color" to can reserve the original shadow like this
ADONG Cassidy 09-17-2005, 08:01 AM I think this is about as close as we are going to get to white without a huge amount of mucking about, given the collar etc. I made two channel masks, one of the red area of the shirt and the other of the lower band of the shirt and then combined them into a single mask. After adjusting the colours down to as approximate as possible, I then returned to the mask of the red areas and reduced it further to blend with the lower shirt and collar. And yes, red does bleed both in photoshop and in the wash Frode 09-17-2005, 10:36 AM Hi,
Menu: Select > color range. Use the eyedropper to select the red. Use Lasso tool to subtract selected areas in the face.
AL Levels, lighten so you can reach white in next step. See screen shot
AL Hue/Sat. (screen shot)
This is a fast and easy way to do it, so if you like the result it will take only 2 min to do it.
Photoshop: If you miss a bit with the selection, you can paint in the masks of the adjustment layers, just to finish it.
Frode Panpan 09-17-2005, 11:27 AM Excellent result, Cassidy. And so far, the only one that complies with Nanls's reuest.
And yes, red does bleed both in photoshop and in the washInsist on color-fast images.

Not bad for 2 minutes, but the shirt is pink and you didn't whiten the grey part of the shirt.
Pierre Frode 09-17-2005, 12:20 PM 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.
:pleased:
Frode Cameraken 09-17-2005, 12:28 PM 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. :lol:
That’ll be 1$ donation to RetouchPRO.
Colour corrected for free.
Ken Frode 09-17-2005, 01:48 PM Nice work, Ken!
You show us just the way to do it :D
You did a nice work to, Cassidy!! If you use the combined mask and a new AL, you get the white.
Frode heyrad 09-17-2005, 02:30 PM 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

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.
Maureen :) Nanls 09-18-2005, 06:00 PM 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.
~Nancy~ edgework 09-19-2005, 05:28 AM 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. realaqu 09-19-2005, 01:24 PM 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.

Thanks for your comments.

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.
Ken Cassidy 09-19-2005, 08:59 PM Now that looks like a white top Nanls 09-19-2005, 09:45 PM Ken, exactly the outcome I was looking to accomplish. realaqu did a nice job, also. Could you guys list the steps you took in your copious spare time, for future reference. Thanks in advance!
~Nancy~ Cameraken 09-20-2005, 09:34 AM Hi Nancy
Thanks for your comments.
I used the channel mixer to do my second picture.
Duplicate the Background
New adjustment Layer > Channel mixer. Check the Monochrome Box and move the Red Slider to 106. This changes the Red Shirt to White
Select the Grey area. Then
New adjustment Layer > Channel mixer. Check the Monochrome Box and move the Red Slider to 80 and Green slider to 40. This changes the Grey Shirt to White.
New layer and Clone out the join between the Red and Grey areas
Select the Original white areas (Collar) and reduced the levels to match the shirt.
That’s the Shirt done. But the whole picture is now Black and White.
Duplicate the background again and drag it to the top of the stack, add a layer mask and paint back the White Shirt.
Hope this helps.
Ken Nanls 09-20-2005, 11:58 AM Hi Ken,
Thanks for taking the time to list the steps you took; it is appreciated. I followed your steps but then had two adjustment layers, that were monochrome, (including his face) on top and the duped original underneth (refer to pix)... I started again but this time selected just the shirt before I did the adjustment layer, and followed your steps from there (had to change some of the values on the channel mixer). This is the end results (which works!)... If I had followed your steps exactly, how would I merge the adjustment layers and the duped original and keep the color in the boys face? Thanks again,
~Nancy~ Cameraken 09-20-2005, 12:17 PM Hi Nancy
I’ve just amended the instructions. Sorry if they were not very clear.
Your way works just as well.
Ken Nanls 09-20-2005, 01:02 PM I just figures another way.... to the same outcome. From your instructions where there are two adjustment layers, the original and the duped original. I turned off the original layer and "merged visible" the the other layers. With the history brush set to the original (after adjusting curves) I used the history brush to paint the boys face back in.
Thanks again for your help Ken! :bow: It's great being able to find new and easier ways to work...
