If you’re having problems with the exposure on your digital camera and the device doesn’t have an AEB (Automatic Exposure Bracketing) function, , then you basically have the choice of taking the shot as either an underexposed or overexposed image. If it comes down to it, you may want to go with a slightly underexposed photo instead of the overexposed option.
Basically, the reason for taking the photo underexposed is because it’s usually easier to fix and adjust it than it is to edit an overexposed shot. The way to do it is by using some type of photo editing software.
An underexposed image will generally record and keep most of the details of the image, even though you may not be able to see it with the naked eye. You can usually adjust the photo to the proper exposure levels quite easily in a photography software program and this will be able to bring the details out.
An overexposed image will typically record and keep less details and it’s quite a bit harder to adjust it in a software editing program. The best solution of course is to have the proper exposure when taking the photo. But if this isn’t possible for some reason, then try going with an underexposed shot and fixing it later.
