Planning on getting a dslr and filters to shoot black and white. I had noticed when converting color to B&W with my point and shoot using PS I would end up with way to much noise to get the tones I wanted. Some pictures I ended up discarding or settled for the noise. The camera was a 4 megapixil, now defunct With a higher megapixal camera and lense I know there will be much less noise during B&W conversions. I always try to get the biggest bang for my buck, so I was wondering if using filters for B&W would really make a difference with noise levels ? I plan on shooting raw if that makes any difference or not. I tried searching for answers but there is very little written on the subject.
