View Full Version : Colorizing B&W

09-07-2010, 07:07 AM
I occasionally need to highlight something in a black & white scientific image. So far, I've been using crude methods like 'select color range' in Photoshop to make a new layer with an overlay color. It's not a very good solution, and I've been thinking about better methods.

One idea is using a LightWave gradient texture. I set up a color gradient and base it on the lights and darks of the base image. This can easily look cartoonish, though.

Any better ideas, in LW or PS?

This is a good example. The medium gray stuff at the top is corrosion. I would have preferred the corrosion to stand out in warm colors, with the rest in cool colors.

Is this what you mean, or is this too crude?

That's pretty good.

I guess I'm more looking for an automated solution. I think the 'gradient based on previous layer' is going to be the best idea for me, for now. With VPR, I can drag the sliders and see the results right away.

There might be a secret for me hiding in the Math Filter plugin, but I'm not clever enough to find it.
