The small but high-quality B/W magazine LensWork is now available in various digital versions. They do good work, and a lot of it.
It's impressive that they have a lot of online work on the web, and also versions now for both iPad and Android.
The yearly price for subscription is only thirty bucks, highly reasonable, just like when founder Brooks Jensen sells his art photo prints. I have one of his portfolios (October Seas), and they are lovely prints. It was $145 for twelve prints, that's normally what you pay for one or two prints.
