1. Just because your camera tells you its battery is full in the morning does not mean it won't go from full to empty after the next twenty pictures you take. So a word of the wise - never trust your camera display and load the battery whenever possible. Lesson learned.
2. Your camera battery will die in the exact moment you decide to go from "just taking some pic's for the family album" to "this will be the most amazing shot for my shop". Seriously, it did.
3. Even though you might think you are snapping away crazily there will always be someone who will snap away even crazier. Preferably this will be the person sitting behind you on the bus who'll supply an annoying click-click-clicking soundtrack to your journey.
4. Handling a simple compact camera to take a picture of a fellow traveler might make you feel like a total klutz, because you're far too used to your own fancy state-of-the-art equipment. Suddenly easy-peasy takes on a surprising difficulty level. Pathetic, I know.
5. Instead of trying to take a picture of someone who's a head shorter than you are (that'd be the lovely lady from the Philippines who had me go through lengthy photo sessions, because apparently I exude a certain photographic confidence handling a camera) from your own giraffe-height POV, crouch. Don't be embarrassed, just do it. Works like a charm.
6. It might not seem like a big deal to lug around your camera equipment all day long, but even a harmlessly sounding kilo (a bit over 2 pounds) can take its toll. Carry that thing around for hours on end and you'll kill your neck and shoulders. Some days I had to leave my camera in the hotel, because the pain had got so bad. Next time I will rent a mule to do all the carrying for me.
7. In case you go to Scotland (like I did) and someone asks you to bring back photographic proof of what's really underneath a kilt, don't be afraid to agree. Then find a shop with kilts on display and angle up your camera to get the perfect shot. If no one mentioned the kilt had to be worn, you're all set ...
Know y'all know what's to be seen when you risk a glance up a kilt ... darkness, apparently.
