One of my favourite things to do is to edit images. This can also be called 'sequencing', but has nothing to do with Photoshop or any other computer program. Editing for me, in the true sense of the word, is akin to editing a piece of writing. I start with a bunch of pictures and little by little, the number is reduced until a point is reached where I feel that I have the essence of the work with the least number of images possible. If there is doubt, it's out.
Editing is a really pleasurable part of photography for me because it is here where the work starts to tell me what it is about, rather than the other way around. As photographers, we have control over what we shoot, but we don't know how an image is going to sit on a page, or in a series, until it is printed and laid out on a table and seen amongst its companions. This is where images come to life, as it is equally where they can die.
I would take a guess that I have 10-15 unpublished series of photographs that have been shot and edited. Many of these (perhaps all) will never be published. Some are short bodies of work that have been completed in a few weeks, some in a few hours. Others are longer, one of which I have been working on for ten years on and off (and has been through many stages of editing). I used to feel a mad rush of desire to make a body of photographs and get it out as soon as possible. These days I have the same desire to make the work and edit the images into bodies of work, but the desire to publish them is less intense. For me, the real fun is in the making and the editing.
I'll probably publish quite a few more series' of pictures in my time, but the pleasure (and the reward) comes less and less from showing the work to others, and more from the personal drive to make work and see what it looks like printed, and in a series.
