I started doing photography back when you had a camera loaded with film took your photos and went into the darkroom, developed the film and then went to the enlarger and did B&W prints.
I am discovering the differences between the old ways and the new ways, and processing digital images via software in a comfortable chair, instead of in a darkened room with chemicals.
I believe that there are some guidelines for photography, but no set rules as everybody has different tastes and ideas of what makes a great photo, and there are always shots that just work as they are. Using software to edit and adjust your images is ok.
As long as you are proud of your finished work thats what counts, you dont need to be concerned about pleasing everyone, you cant.
