I am currently using an orthographic camera in my scene, and I tried to used the camera DOF effect and to my surprise, it didn't work, or perhaps I couldn't make it work. I tried to make the camera perspective again, and it worked. Is there any reason why this is happening or is there a solution to this ? I have seen orthographic artwork rendered with keyshot and software like magicavoxel and they both have DOF in orthographic view. Is blender able to use DOF in orthographic view at all ?
