I really enjoy taking photographs for the blog. It keeps me visually sharp - looking out for good subjects, for something slightly unusual perhaps, or funny (at least to me).
Sometimes the photo is just to remind myself that simple things can give a lot of pleasure.
A friend uses Blipfoto - a lovely free site where you publish a photograph each day, with or without text - a visual diary.
It is really worth a look : www.blipfoto.com Perhaps you'll join....
