Whole volumes have been written on photographic composition, which will explain things far better than I can. Not being artistically trained, I’ve tried to read a few, but I’m not sure how much has sunk in – I think I’ve learned more by looking at the work of others and seeing what works.
I tend to compose intuitively, but not randomly. Although I understand things like the rules of thirds, I don’t set out to either follow or break these supposed rules. I just shoot what looks right.
The only principles I tend to follow are to either have a point of interest (focal point) or if not, I try to at least make it a picture of something. Oh, and fill the frame!
Having sat and stared at my pictures for long enough, here’s some themes I’ve picked out.
Wonky Angle (no-one said the picture had to be either portrait or lanscape format!)
Looking Through a Window
Hope this is of use to someone!
