Default B & W Conversion In PS CS

I have some color images that I think would look better in black and white. Does anyone know the correct percentages (red, green, blue) for the gray output channel? Allso, what is the purpose of the "constant" slider?

Well - there's several ways of doing BW's with Photoshop. Why not take a look at my website. There's full tutorials of 5 different ways of getting BW's. I think you will like the "acwanced way", which gives excellent results. Look in the menu under Photoshop.

Steve
The percentages will vary from subject to subject, but a good starting point for digital images is 40 Red, 40 Green and 20 Blue.
If you are using a scanned image, use 60 Red. 40 Green, and zero blue - most of the grain is in the blue layer.
You will usually need to finish off with a Curves or Levels adjustment layer.

My site has a couple of tutorials, a learning gallery, and a PS action set for B&W conversion.

Learning Galleries

PS Action Sets

BTW, Image|Mode|Grayscale in PS uses 38% Red, 45% Green, and 17% Blue.

Cheers,

Mitch
