Let me point out at the very start...I am not a professional photographer. I do photography as a hobby, I travel around and photograph just about anything, and I am retired.
About my photos:
I label my photos by: 1-what the subject is; 2-Where the photo was taken; 3-Cygnus Productions, (as
Cygnus is Latin for Swan - (my last name)); and 4-the date the photo was taken.
I use a Canon PowerShot G5 camera with the TeleConverter 1.75x lens. I purchased this Point & Shoot camera about 6 months before they came out with the DSLRs. I have been able to take some really excellent photos with this camera.
I agree with you on taking plenty of memory and lots of batteries. My camera uses rechargeable dedicated batteries, so I have a car and AC charger with me at all times. I also take with me if I am going for more than one day, my laptop computer; a place to free up my memory chips.

- Let me add a TIP. In your tips for taking pictures at the air shows, maybe I didn't see it, but while taking pictures of planes or jets in flight, tracking the subject is important as you may get a picture of nothing but sky if you don't. When I track the subject, I have the camera on the subject and follow the subject, take the picture at the proper time, continuing to track until after all the picture(s) are taken. I can sometimes get several shots while tracking the subject.
I am sending a photo of the Blue Angels doing what is called a Star Burst. A telephoto is definitely needed as they are so high up that they are very small. It was also a slightly hazy day when I was at the air show. I made about 100 copies of this photograph and went to our local Veterans Hospital and gave military veterans copies. They enjoyed them immensely. I also am sending a photo of a Harrier Jet going down the runway for a short take off.
I hope this was a little help.
