How passionate? I think of every minute as an opportunity to shoot a photo.
Can't tell if it's passion or addiction but I get depressed when I don't get a chance to click.
It gives me pleasure to look at the photos too, and when other people feel the same way about my photos it's quite inspiring.
I have a couple of friends who share this passion and I feel lucky for that. But it doesn't beat forums like these and the internet where you can showcase your work.
