I'm about to go abroad for some great photography fun! (Are you?)
Obviously, I'm going to pack cameras, lenses, batteries, etc. and depending on where you're going and what you're shooting, your list for what to bring for that will probably be different than mine.
Before you start packing every piece of photographic equipment you own, there are some things you need to pack and check on first!
Make sure you have a guidebook for the place you're going. Read it. Now pick the places you want to see, and think about what lenses you might need to capture them in images. Set only those lenses aside, along with two camera bodies, batteries and chargers, and at least two memory cards.
