Sometimes it can be difficult to get the right light when shooting. If you increase the setting a little bit, the result is over-exposure, but if you decrease the setting a little bit, the result is under-exposure. So which one is better to choose?
If had to choose, Mimin would prefer the one with the underexposure. Why is that? Because usually underexposed photos are easier to edit after the shooting process. When you edit with Photoshop or Lightroom, you still get more details and information in the photo compared to an overexposed photo. Now, with the editing process, you can restore that detail. Meanwhile, overexposed photos not only lose a lot of detail and information, they also have fewer editing options.
