Joel
I found this old thread, Richard Lane was looking in to Zenfolio
http://community.the-digital-picture...light=zenfolio
Here is a quote from one part of the thread:
"@Rick, I found out that Zenfolio downsizes their viewing images to 1550 x 960 as the max, you could even downsize this quality further. They claim that is done to protect the photographers images, and load the images faster, but now I'll have to explain to people that the images will look better when downloaded or printed. I'm not sure if that feature could be turned off."
This might explain what I am seeing, but maybe some others can give us some insight on Zenfolio.
If you are trying to sell your work Joel, I think for these types of pictures they need to be the highest quality. If Zenfolio is really worried about people stealing the work maybe it should have a watermark. People aren't picking these type of shots for portraits of family, they would be printing for art on the wall.
Good Luck
Rick
