I am a UK based photographer. It is a part time occupation for me. (Although I wish it was full time!) Stock photographs are different in many ways to personal type images you might keep at home. So images have to say something, or have some message. I try to imagine who would buy the image and what type of media it might be used for. I wish i knew where my images are being used it would be fun to know.
Best regards to all readers
NIKON D70 SLR, 6.1MP,
Usually people I know in situations that just happen rather than manufactured compositions/lighting.
