Shadows are a double edged sword
In photography, they can be used strategically to enhance shapes and form or even the overall tone of the image. But at the same time, inconveniently located harsh and harsh shadows can just about destroy an otherwise beautiful photograph.
Some of the photos you may not want in your shot are those that appear on the background behind your subject. This can occur commonly in studio or other indoor settings.
But fear not, there is a fairly easy way to correct it with the use of Photoshop or most other common editing tools. (This works especially well with either black or white backdrops but may work adequately with other really dark or really light colors as well).
Once you’ve opened your photo and decided what shadows much be removed, select your Dodge/Burn tool in Photoshop or the equivalent in another program.
If you’re working with a white (or really light backdrop), you’ll want to use the dodge tool. The reverse is true if you’re image has a black (or really dark) backdrop.
You may need to adjust the exposure and brush size. It is best to start out with a relatively low exposure such as 25% too see how things look. You can always adjust it to a higher or lower level if need be.
Use the tool to cover over the shadowy part of the background that you want to remove and that’s really all there is to it.
It may take some trial and error but you’ll get there.
