The digital manipulation should be done in such a way that it adds to your concept and does not end up being a major part of your pictures—what should stand out is the concept. Also, while bringing more variety to your series, keep in mind what connects the pictures and make sure that the link is not broken. It could be similar colour tones, structures or even something as simple as similar angles. You need certain elements to be consistent in all the photographs.
