North American Nature Photography Association
NANPA, the North American Nature Photography Association, was officially established in 1994 by a contingent of nature photography devotees. NANPA is the first and only association in North America committed to serving the field of nature photography. The stated mission is to provide education, foster professional and ethical conduct, gather and disseminate information, and develop standards for all persons interested in the field of nature photography. NANPA further seeks to promote nature photography as an art form and a medium of communication for the sciences, nature appreciation and environmental protection.
This is not only the best eraser I've ever used, it's the ONLY eraser I'll ever use, despite the best sales pitches in art shops to get me to change. Cleans superbly, soft to use, no discoloration on the paper and cheap as chips...I don't believe it has a competitor
I'm going to go ahead and give this product 5-Stars, even though it's not what I was looking for in a pastel paper. I'm into photo-realism and fine details ,and there is too much texture for that, even after blending. The quality is right up there, and there is plenty of tooth as I did do some practicing on a sheet. I'm sure I'll find a use for it. It's just too nice to return.
