A few nice Maintenance images I found:

This was taken while we tried to fix the rollers on my polaroid back (which are still giving me grief).
I wanted to try and depict the classic home camera maintenance scenario – kitchen roll, dust blower, super glue, various camera parts all scattered across the table. I like this inclusion but I think the placement of the hands lets the image down: I think a little lower would be better.
