No. Not an ERASER!

I worked on Ro's tutorial and the same photo that everyone else did. Eventually I arrived at a question that has nagged me for a while. First, I have only recently started understanding that my instinct to "paint over" problem areas is prone to not looking natural. Even cloning-over and the spot-heal tool leave something to be desired. Meanwhile it seems that subtractive techiques are more likely to give natural looking results.

Back to the photo, I was left with some veins in her chest that while natural don't seem appropriate for glam stuff. I wanted a Minus <some color> brush and I've needed it before. Does any one understand what I am looking for and how to do it in Photoshop CS2? Alternately, how do you pro's delicately remove something like this?

Use Sponge tool set to de-saturate. (adj to about 10%)

I don't want to take out the skin color. Only the 'blue' of the veins just under the surface of the skin. Let me rename it a "Minus <A Specific Color> Brush". So, I need a Minus Blue Brush.

Would the Color Replacement Tool in Photoshop CS2 help you?

Image>Adjust>Selective Color and Image>Adjust>Hue/Saturation may be what you need because they will allow you to be very selective about the color range you wish to change. Alternately, post the image here and you will get advise specific to that image.

You can try duplicating the layer and setting the blend to color.

Then simply paint in the color you would like.

I feel dumb for asking, but which photo are you talking about?

Based on your description, either do a second pass of the degrunge method targeted specifically at the veins, or use the healing brush.

Is almost an acedemic question. Veins being something under the skin that colors the fairly transparent skin. Since the veins are blue and skin is not, there IS a way to just remove the blue or significantly reduce it. I 'painted over' on version thats attached to a prior note in this thread. Not too good but I didn't spend much time on it.

I suspect that you could use the "advanced blending option' on layers - that's something that I currently have no use for (don't know how to use it).

I had only seen the head shot from the tutorial.

For something subtle like that, just use the healing brush on a separate layer, but change the blend mode of that layer to color. Alternatively, you can just set the heal mode to color.
