Is there any way to speed up DOF PRO for high-resolution print or film images?
While the final output of larger images will always demand longer processing times, some preview shortcuts can facilitate the workflow to reach your desired result. When you wish to do a full image render for previewing purposes, set your Res to a lower value such as 1:5. When you render your full image, your result will be pixilated because DOF PRO only processed every fifth line of data. However, this will serve as a good indication of what your final output will look like and the processing will be significantly faster (25x). Once you are satisfied with the result, set the Res back to 1:1 and render the high quality image. Please note that setting high levels of DOF may significantly increase rendertimes so careful use of this slider is recommended.
