Camera alignment when shooting large painting on easel?
4x8ft painting. Got the lighting worked out. But getting the camera aligned -perfectly parallel- with the painting on an easel -and therefore slightly tilted backward is not working. Tried the mirror trick using a small mirror taped(!) onto the painting at the very middle. Didn’t work because given i am about 10-12 feet away from the painting nearly impossible to even see the lens in the small mirror. Plus the painting surface is not even, so….even a slight unevenness can throw the alignment off by an enormous degree.
So far have some (near)perfectly lit shots that are sharp in one area of the painting but unsharp in rest of painting.
Using D850 with Micro Nikkor 55mm MF lens.
Note: hanging painting on wall is not an option in this space. Neither is photographing the painting outdoors. #hobby
