Thread: Light Box that most people have

I think your first photo in post 8 shows what I'm talking about quite well. You can see where you are getting the card reflected in the razor. That makes it quite clear that the curved lines farther out are the rings on the bottom of the microwave. So if you wanted to aim for a uniform reflection, you'd need to cover the things in that area with something uniform. Putting some white paper or tissue paper on the bottom of the microwave would address that.

Then again, not everyone aims for a uniform reflection in the blades. I use it because, for my purposes, I want my photos to show every detail (imperfection) in the razor.
