RE: Grayscale to color conversion question

I found that rather difficult compared to the method I used. If you want precise values then you need a different utility.

As explained previously, convert from greyscale to duotone affords you much more precise control for what you are after

Yes, you can do it in Photoshop. I did it once but I have forgotten how during my culture shock. I will investigate. Open Photoshop: Open grayscale image, convert to RGB Image>Adjust>Curves Select "red" move curve to select part of gray scale to be red Select "Green" ditto for green Select "blue" ditto for blue.

If you know what I mean!! I guess it would be like taking a spectrum and assigning each color a numerical value from 1-255 and then "mapping" these onto a grayscale image. yes? no? how? Help appreciated either way. andy
