When you are taking pictures of items you plan to sell online, it is important to choose a proper background color. You want a color that makes your product stand out and look good. For example: I normally photograph items for my Etsy stores against a white background, but there are certain pieces that get way too washed out with white. Take a look below at the same hat, first pictured against a white background, and then against black. I haven't photoshopped anything, only the background colors were changed. The white background washes out the white feather on the hat, practically making it disappear. On the black background, the white feather stands out boldly, and the darker background also seems to make the red felt POP out.
Just something to keep in mind the next time you do your photoshoots!
