A somewhat overloaded and often confusing term when talking about photography is “editing”.
Editing a set of images is the act of reducing that set to those photos that you plan on working with further. These images are often referred to as “picks” or “selects”. A final edit is the reduction to just the images that are the final result of a shoot or larger photo project.
Editing an image is the task of doing some post-production task on an image that changes it’s presentation in some way. For instance, cropping, rotating and changing the color balance is editing an image.
The question, “What program do you use to edit your images?” is vague and something like it usually starts this conversation.
