This will probably raise a few questions - here we go
What type of camera bag do like like to use?
I find if I have easy access to the car, I like to use a small square bag, top opening with enough room for a camera and 3 lenses and a flash.
If I have to lug the stuff around, I like to use either a backpack type or a sling back type of bag.
I just picked up a digital underwater camera, I purchased a small camera bag, enough room for the camera, a spare battery, and 2 extra memory cards.
I have a separate bag for the laptop,
