The camera still reads in colour, as each pixel has a red green or blue filter placed on it. So when the camera makes a B/W picture it has to decide how much brightness of each colour it should take to decide on the brightness of the grey.

Try taking some colour pictures and splitting it into the Red, Green or Blue channels to see how much light you get. Taking from the red channel is like putting a red filter on your lens. Deciding how much of each colours brightness you take alters the photo.

Don't have PSP so I struggle to advise you on how to do this on your PC.

The latest edition of Practical Photography has a whole section of black and photography. It seems it's best to photograph in colour (if using digital) and then convert to black and white with software. Apparently using the b&w option on most digitals means you don't get much contrast and you need to adjust it with software.

Hi Stuart

If you've been getting Practical Photography for a while (and still have your old issues) look back at page 42 in the May edition.

It shows how to turn a colour photo to black and white and then how to make it look as good as a "proper" black and white film photo.

Yes, of course, it shows how to do it in Photoshop but you shouldn't have too much trouble following it in PSP.

A big advantage to doing it in the computer is that there's more than one way to do it.

Rather than just clicking the Grey Scale menu item, I like to try the Colours->Split Channel->Split to RGB command. This creates three B&W images, one from red, one from blue and one from green. Then you can compare all three images and see if any look better than a simple desaturation.

Sophie - that's providing the camera has this mode. You can do the same with PSP and Photoshop (I believe).
