I do not know if you know the web www.behance.net i love it, there you can find design, architecture, photography and more different portfolios of many artists. You can find amazing works and you can stay for hours looking the portafolios, i recommend this site for inspiration or just look.

Here i select 2 artists, from the photo manipulation section:
Ibai Acevedo, Barcelona, Spain, i select some photos taken in an incredible way, under water, a wonderful art, which hold some beautiful tones, body positions, textures, everything amazing.

And the second person called Marc Yankus, NY, United States, i select some pictures of different landscapes in the city, the sea, with people or not, with a treatment that fascinated me the forms, diffuse light, the grain of the photo.
