I like realistic paintings where artist tries to show us exactly the part of his sight as it was in reality.
It is not so easy to make such paintings because everything needs to be perfect and you have to care about each tiny detail.
If you look the following collection of images which we attached to this article, in one moment, you might think that you are looking at photographs, however, the truth is that those are realistic paintings painted with oil paints by Richard Estes. As you can see, those paintings do look like they've been made in 70's.

When we talk about street art most of us immediately thinks about graffiti and similar artworks. Graffiti is interesting artistic way, there's no doubt about it, but this is not single way of performing street arts.
The best example for this are artworks of artist Liliwenn who is creating some of the most interesting street artworks...

Combination of photos from past and from present can be very interesting way to create great artworks.
Sergey Larenkov is Russian photographer who managed to create few of such combined photographs. He found some photos of places in Russia and rest of the world from World War II and he took photos of same building again, from same angle. Then, he combined old ones with new ones to get that "ghost effect"...
