Reference for extreme close up face details (pore / skin details)

hugosk4

Hi i'm looking for a website that I've seen in a tutorial once. It's a website were you could zoom super close on super high resolution photos and you could see all the pore details. Is there a character artist out there that may know that website? It was a free website, not 3d.sk

Thank you
