I could speculate on this, but it would be much easier if you posted a copy of the orginal and told us the percent you set each channel. Then we could test it.

Garfield, you have two questions.

On channel mixer, I agree with Andrew - save out the channel mixer adjustment file from the channel mixer dialog (save button) - which would be .cha files. Also crop out a small section and zip them both up for the forum to inspect...or a more concise and long winded explanation would be needed.

On multichannel mode - I am not following you. MC mode simply 'separates' the original channels into g/scale channels which are no longer in a mode such as RGB/LAB/CMYK etc. It is usually a temporary work mode from one space to another, such as converting true duotone mode into spot channel EPS DCS 2 files. MC mode has specific uses - but not for many common users. What exactly are you doing (again, concise step by step detail is needed).

I too would like to help, but I am feeling a little lost. <g>

Stephen Marsh.

If you are using the channel mixer to convert to black and white then the "add up to 100%" guideline is a good one - but you need to have ticked the "monochrome" box.
