I'm doing an assignment for my photography course, and one of the assignments is discussing the use of coloured filters in B&W photography. Does anybody know how I can replicate this in photoshop elements? I've tried playing with the colour channels in the 'convert to b&w', but this doesn't give e the correct effect. Any help?

Failing that, does anybody in the Cardiff area have any square colour filters that I could borrow for a little while?
 
Plugins like Topaz & NIK have the filters built in for B&W conversions

Adding coloured filters to the camera and shooting digitally.. in colour, does not work. Add a red filter to your camera, and you just get a predominantly red image, then when converted, will look awful, and northing like a red filter shot on black and white film. If you shoot in B&W that's a different matter, but then you are limited to shooting in JPEG or TIFF, so shoot in TIFF, not JPEG. You can't do it in raw though, as you're capturing in colour.


As for doing it digitally, does elements have the equivalent of the B&W adjustment tool that PS has? If so... see my post in this thread.

Elements doesn't have the filters built in. You have to install a plug-in. Topaz B&W Effects 2 has the usual red, orange, yellow and costs around £30 if I remember.
 
Thanks guys. I'll have a look into it when I get home.
 
Nik silver effects is pretty good.
Does your camera have the filter options built in? many have colour filter options in the black and white user profile. If it does shoot in raw and jpeg and you'll get a black and white jpeg and a colour raw, you can then open both and match the colour pic to the black and white with the sliders and save out presets for next time.
 
I suddenly remembered that my old Canon 20D can do this in camera, so used that. Worked perfectly! Thanks guys for your help!

Can it do it with RAW though, and are you using optical filters? If you just remove colour, you've no control over tones.
 
I did think about buying a set of optical filters, but I'd only use them for the purpose of this coursework. No, the camera only records colour in RAW. You have to shoot in Jpeg, and then the camera applies a digital verision of the filter to replicate the tonal changes. So far, it's done the job.
 
You can open a jpeg as well in camera raw (in the later versions) open the raw and jpeg in camera raw, tab back and fro as you ajust the raw to black and white to match the jpeg, then once you have it matching you can save it as a preset, yellow filter or whatever for next time, then you won't need to shoot in black and white.

Then I wouldn't shoot B&W in camera. A) It's a 8bit image, and B) you've no control over tones.
