One of my favourite cameras for dragging around when out and about is my Canonet. I really like to feed it Delta-400 because it is a very useful film for just about any circumstance. There is, however, a problem. When I encounter circumstances which demand 'sunny-16' I get about 1/2 to 1 stop of overexposure because the Canonet tops out at 1/500 at f16.
I have heard that a ND filter can address this problem by giving a photographer a stop or more of flexibility. A couple of questions:
1. Do ND filters degrade the image appreciably or are they actually pretty good?
2. If an ND filter is labelled ND-1 or ND-2, I assume that it means that it will give you 1 or 2 stops respectively. Is this the case?
3. Any other hints or suggestions?
