This is pretty simple and easy tutorial for all of you who are looking to enhance your rendering in Photoshop.
You’ve rendered your 3D object in your 3D program and ended up with an image (.jpg, .gif, .tif). Load your image in Photoshop.
- Copy the layer and apply Gaussian Blur (Filter -> Blue -> Gaussian Blur) to the copied layer. Set the ammount to your liking.
- Change the Blending of copied layer to Lighten/Screen/Overlay (Layer -> Layer Styles -> Blending Options). Depends what kind of effect you want.
- Add a Brightness/Contrast layer and link it on the blured layer(Layer -> New Adjustment Layer -> Brightness/Contrast). Play with the settings.
