differnce between grayscale and adustments..black and white? oh..i just worked that out whilst writing.. one completely removes the cmyk or rgb, the other..leaves it as that..but removes the colour. 

ok.. hints, advice in changing cmyk/rgb into black and white? I got the filter bit..but what would be an ideal black and white image? what do you go for? 

also... in terms of levels and curves..

suggestions, advice, anything gratefully accepted. 

Me, I like changing the color mode to LAB, and then I select the Lightness channel and discard the others.

One thing.. Greyscale is still black and white.. it just allows minute changes in the image. An excellent example of what can be done with "Black and White" imagery, is the work by Ansel Adams. One of the advantages of using B&W is that, if you make the image slightly "grainy", you almost automatically get a "gritty" look.. useful for highlighting, for example, just how bad slum areas are.. or how dirty some cities are, (usually, this is for pointing out pollution). Conversely, Greyscale can be coupled with filters to give the images an "old" look. Greyscale/Black and White, are still being explored today, with photographers, trying for particular emotional effects. Lou.
