replace color and color replacement tool questions

Hi,

firstly, what determines whether one chooses to use the color replacement tool or image>adjustments>replace color ?
Secondly ….

I have tried several tutorials and can’t get either of them to work the way that they apparently should.

I have been trying them on skin tones and the only choice that seemingly makes any changes at all is luminosity. Color, hue and saturation appear to have no visible effect at all.

I understand that changing a car from blue to red is using very different colors but I would have thought that in principle changing one skin tone (more greenish to a more natural existing color in the same image for example) to match another should work.

Any help or tips would be appreciated.

thanks

The Color replacement tool works by taking a sample of the area in which you first click and then applies the foreground colour to any colour that matches your sample. You can use this to correct red eye. Set your foreground colour to a dark grey and click on the reddest part of the eye. Be careful though if the subject has similar coloured clothing.

Image>Adjustments>Replace colour Luminisity? Lightness? Have you selected a colour to replace with eyedropper? You should see your B&W thumbnail change as you select your colour and play around with the fuzziness slider (more white areas appear, that is your selection. What colour is the colour swatch?
Open your image, select Image>Adjustments>Replace colour and click an a skin tone.Adjust the fuzziness slider to include more or less of the image, (watch the thumbnail) and when happy with selection, Hue will change the colour, Saturation will alter the strength of the hue and Lightness, you’ve already discovered.

Perhaps this is not the case with v8 ?

I have to select between ‘selection’ and ‘image’ when I got into image>adjustments>replace color.

I started with ‘selection’ and played with fuzziness which was no problem and I noticed for the first time that I could adjust hue, saturation and lightntess whilst in the ‘selection’ mode and not just in the ‘image’ mode.

I switched to the ‘image’ mode and selected a color – it seems that I can choose it from either the ‘main’ image or from the ‘replace color’ and the ‘result’ box changed color.

I did manage to change the hue, saturation and lightness but after 5 or six consecutive attempts it was still not perfect and I had also changed the overall tone of the picture. So this would seem like the wrong tool for changing two different flesh tones to match each other.

Perhaps ‘match color’ would be better ?

thanks for the help,

Michael

I wouldn’t use either 🙂

Selection mode will select the whole (main) image if you haven’t made a selection.
The only way you would get a change in flesh tones on the same image is if you first made a selection (marquee tool, QM mode etc.,) around the face or part of the image you wanted to alter. Or you could copy the whole layer, apply your cahnges to it and then……mask in/out the parts you wanted.
