Picture quality of the various waterfalls pics will vary, mainly because my scanner is not that great; about half of my waterfall collection are print pictures taken with a film camera.
However, the later digital pictures should be of higher quality in general. My current equipment is a Canon 300D (Digital Rebel), and most scenics are taken with either the kit lens (18-55mm EF-S) or a Canon 24mm f/2.8 prime. I will try to specify the camera data along with each picture post.
For waterfalls, I have a liking for the "milky" effect of taking a long exposure, so most waterfalls pictures will exhibit this quality.
Also, I live in southeastern Tennessee; so, many of the waterfalls pictures will be in this region.
