Title: adjusting colour Post by: PopPicker on August 28, 2009, 11:22:38 PM I guess I'm a bit dense, but is there a way to adjust the overall colour of an image within Qimage, in other words if the test result is a bit magenta, can I remove that or do I have to go back to Photoshop?
I've played with the Sel.Color tab, but nothing actually seems to change for me. I know I'm doing something wrong, so can anybody help me?

Of course you can reduce or increase any or each of the RGB colors in the saturation section of the same batch screen. Can you provide a little more information? You are referring to the screen image and not a print, right? If you are adept with Levels and curves, you can switch tabs to those and change the RGB to a color and raise or lower that intensity too.

Sounds as though your "test result" is a print. I have been through that with certain papers. In the full edit try going to -3 Red and -3 Blue in the white balance. You'll have to play to see what works. Since there are only two colors and no sliders, you have to treat it like enlarger color printing. I have to disagree with Fred about using saturation. Messing with that for a color balance can cause tonal shifts in other areas. Levels/curves is dfficult to get an overall change if that is what your problem is. Since you have PS, I have found it easier (if it doesn't hit in QI with a slight adjustment) to go back to PS and use Image>Adjustments>Photo Filter for the appropriate overall shift. I find 3-8% is plenty. I just save it as xxxxxA so I still have the original.

I have had some good results but am in need of a fuller non tech tutorial to get the full benefit.
I asked a painter chap I know but he was of no help as he did not understand digital imaging so did not know what I was on about. He could real off mixing colors ok but I could not translate into the Qimage grid. jeff |
