I now of course sometimes take pictures. They do brigten up my blog. My technique is to take a picture when I see something I like, or some scene I can weave into a blog posting. I don't do any planning of the visual aspects.
At my mum's house there was a book called "Creative photography" by David Kilpatrick from Marks and Spencer publishing. The book was full of tips and techniques and frankly an eye opener. I will think more about foregrounds and backgrounds. I have even looked at the instructions of my camera so that I could learn about the zoom.
