I'm a 64 year old gay teenager who loves to do landscape photography especially waterfalls. I have done a great deal of HDR photography while I was learning it. I do not, however, that HDR methods are ideal for waterfalls because of the need to choose between the optimal shutter speed--slow to make the water silky--or the often artifact loaded surrealistic results obtained with HDR. HDR, however, is very fine for landscapes per se.
