When I use Quick Edit to transfer a screen capture to PhotoShop, then edit the image, save it, and Apply it back in Blender, the image that is projected on is noticeably darker. This causes lines to form all over the model where the borders of the projector are. Here is an image. Does anyone know how to work around this?
EDIT: The image to the left is using Perspective View and the image to the right is using Orthographic View, There is a visible color bleed from the edges of other models that overlap for the projection.
I didn't add a .blend file since I restored Blender to the default settings before doing this. Both images were made using 2048x2048 textures for both the Bake and for the External Edit settings.
