Don't read the title or blurb beneath each one, just look at the pictures: https://secure.flickr.com/photos/kelvinokaforart/.

Okay. Now go back and read read what it says under the pictures...

I'd be ecstatic to be able to take photographs that well. Found via this news story.

Fantastic artist, one or two did look like drawings but most I thought were photographs.

I knew these kind of drawings and saw other ones. Mostly they are in black and white. In color they wouldnt look much realistic.

Search the web for photorealistic drawings.

I think mainly projection equipment is used, which your link doesn't show but in my experience they are follow-the-lines types of drawing.

There is a shot by shot progress of the dog drawing I've seen. It's all done by hand. Amazing

These are amazing. I love drawing portraits myself; http://www.flickr.com/photos/pencil_ninja/sets/72157626201642684/

If I could get anywhere near as good as that...I would make a good living out of it!
