Most likely you have already seen a lot of great tilt-shift photography examples lately, but you probably haven’t seen it done with paintings yet! If you are new to this, “tilt shift” is an effect that gives a real-world scene an illusion of being a miniature model. It can be achieved in two ways : optically (with a special lens) or simulated in Photoshop, by adjusting a photograph’s contrast, color saturation and depth of focus.
“It works quite well with regular photographs, so we decided to try it using paintings to see what would happen…” Serena Malyon, a 3rd-year student at art school, took some of van Gogh‘s most beautiful paintings and altered them in Photoshop to achieved this amazing tilt-shift effect.
“Nothing in any of these paintings been added or removed or had its proportions changed. The effect is achieved simply by manipulating the light in the scene and adjusting the areas of the image that are more and less in focus, as you will see. This is all being done in fun, so don’t take it too seriously.” says the artist.
