I checked out a few exhibitions in NYC last weekend:

Alex Webb's ongoing exhibition at Ricco/Maresca is good. The other ongoing show in that gallery by Bill Barminsky looked quite interesting too.

Alessandra Sanguinetti's solo exhibition in Yossi Milo is available online. The series is also described here. Her earlier work is displayed here.

Garry Winogrand's exhibition in Pace/MacGill through Oc 16 (review here). You should check it out if you happen to be in the neighbourhood.

Howard Greenberg has an intriguing series of nudes by Kenro Izu against a dark shadowy blue background on large format cyanotype over platinum/palladium prints on exhibition. The prints were intriguing. I know very little about printing; so let me just quote from The gallaery press release:

"Using a custom built large format camera, Izu produces 14x20 inch negatives. He then prints the negatives directly onto a fine watercolor paper that has been hand coated with a platinum emulsion. The addition of one to two layers of blue cyanotype adds nuance of multiple tones, bringing luminous abstract forms out of a rich velvety darkness. ....."
