    B&W conversion with channel mixer question

    The question is, what is a good way to do it? I've played with it with varied results, and I don't have a good process down for it. I often resort to converting to grayscale and just adjusting levels. After reading the thread about B&W digital vs B&W film, I felt that it was time to ask. So, what teqhniques do you use to get striking B&W photos?

    thanks?

    Re: B&W conversion with channel mixer question

    I prefer the channel mixer technique, the main thing is to keep the levels adding up to 100%. I usually do this before levels; using levels as a final touch to boost the contrast a little. As far as what numbers to use for the R, G & B channels, it's just experimentation.

    To add to what Steve said, it really depends on your image as to which channels get what settings. There can't be a single setting to cover all images. It has a lot to do with your color balance.

    Here's a link that says what Steve said, but with photo examples.

    Thanks. That link asnwered all my questions. What was especially useful was his note that the slider values should add up to about 100%. I think that's where most of my problems lay. It also answered my questions on how to uses the curves adjustments, which was going to be my next post!
