I've been seeing a lot of photos simulating the effects of tilt-shift lenses lately. I tried doing my own version of fake model photography with few variations from the usual techniques employed by some photoshop geeks. Using the radial gradient tool in the quick mask mode, i was able to select the portion where i would apply the blur. Since we are simulating the tilt-shift lens, it is only proper to blur the unwarranted portion using the lens blur filter. To get a good artificial contrast, the curve adjustment layer is used to blow out the colors in the image. To achieve a level of distortion to impart a feeling of artificiality and to simulate false lighting on the model, i applied some vignetting effect putting some gaussian blur on the extreme four corners of the image. Another desirable effect would be to render some simulated lighting like omni-directional lighting or spotlight effects using the render filter -> lighting effects. The photo above was the result of the simulation of a tilt-shift lens effect of the photo shown below.
