The keys are 1.) keep the camera handy (I have a reflective mesh vest with a front pocket that is easy to get to).
2.) take lots of short shots of interesting things along the way
3.) for gosh (and everyone elses) sakes, edit it and keep it short!
4.) pick some music you enjoy.
I don't care about shooting video ona tour unless someone is paying. And I'm expensive.
For still images, though, allow me to add:
5. Use a wrist strap. I've seen people go down trying to catch a fumbled camera.
6. Offload regularly. Losing your camera means the entire record is gone.
7. Proprietary batteries used to be silly (and all of my difital cameras have used AAs) but now they can last a week. Just be sure you have your proprieatary charger along.
8. Suggest you look carefully at armored or water resistant cameras for touring.
9. Be sure you get a camera you can use. The controls need to be accessible wearing bike gloves. The software needs to be comprehensible.
10. Don't buy more camera than you need. Consider 90% of you images will probably get crunched to tiny jpgs that are one millionth the size of the raw or tiff file. Do you REALLY need to be able to blow your shots up to 20 inch prints? No, you don't.
11. Look for and sign up for a weekend photo workshop a few months before you take off. You will learn how to use your camera under realworld conditions (wear your bike gloves), compose/expose/edit/share better.
As a professional photographer, I used to shoot, say 10 rols of film on a gig, 350 slides including bracketing that would be about 80 setups, in order to get the ten to twenty winners that would pay for the day. I shoot about the same ratio on my own but if I've got an art director along, that dope will have me shooting a thousand images to get one or two hero shots.
