Are your double exposures looking rather pale? Here’s a quick and easy tip – just use a dark backdrop to change that!
The colour black reflects no light at all. Whereas the colour white reflects a lot of light. When doing double exposed shots you want the least amount of light to be reflected in your background.
For my double exposures I always use my navy blue bed sheet as a backdrop/background for at least ONE of my shots if not both. For example in these pictures I took pictures of my dog just on my wood floor, but for the second exposure I put the playing cards on my navy blue sheet.
But here are some examples of double exposures with a both shots on a white background
See the difference?
