In something like PhotoShop, sure, but POV is almost a light simulation 
tool, it needs to follow the correct laws of physics in the first place. 
Sure you can botch it and create something that looks realistic, but it 
won't be exactly physically correct, and usually would require a great deal 
more skill and effort from the artist.  POV works on the fact that if it 
deems something should be 50% brightness, it will make it look 50% 
brightness to you (which is not the same as 50% pixel value).  If it didn't 
work this way it becomes impossible to get scenes with physically correct 
lighting, and then you need to start the whole skillful and time-consuming 
"bodge" process of trying to make it "look right".
