I was messing with filters and whatnot and i found this cool effect that works well with renders. Ill be using this render made by Tidus. First Duplicate the layer and add a motion blur. Angle 0 Distance about 30-35 You should have something like this. Then set the blending type to linear light Finaly go to Image->Adjustments->Gradient Map Then pick the black and white gradient. It should end up to look like this. If its to dark adjust the brightness. Image->Adjustments->Brightness/Contrast And there you have it a simple effect that looks good on sigs. Heres an example of one i made
well i forgot to mention that other gradient maps work well the render feel free to use those as well.
