Hmm..... Lemme start at the beginning...
1. I live in Knoxville, and all my storm shots are taken on the top of a mountain or in some valley, either way, it's a real thrill during the spring, because you only have a few minutes once you hear a storm is coming to get out the door and get to your spot to shoot...here are some things to keep in mind....
A: Do some research and find 1 to 3 spots around your area that you think would make a good night/storm shot. You probably want one that faces in 3 different directions.
B: Pay attention to how the weather moves. Example: Here in the Tennessee Valley, storms hit either hit the Cumberlands and peter out, or get funneled (sp?) from GA. In Knoxville, I usually have about 10 spots picked around town and in the mountains, because once it hits the city, it will either go about 10mi north or 5mi south of me. It sounds complicated, but half an hour paying attention to your weather reports and the geography will get you all you need to know.
C: Once the weather hits, grab your s&*% and get out the house and go to your pre-positioned spot. Set up your tripod, and wait for the storm to come. You'll probably get a successful shoot 3 out of 10 times, but it's worth it.
D: Composition is 9/10ths of the shot. Only take photos of stuff that will look good without lightning, because lightning itself is rather boring.
Anywho, that's all I have to say about that
Some things I've learned is to keep the selection fairly small, and only put the absolute best photos you have in a book. No employer wants to sift through 50 photos somebody has taken. There may be 15 or so great shots, but I keep it a rule to put no more than 20 in mine. Lets face it, not every shot is going to be great.
Keep it updated. I *try* to update mine every 6mo.
No employer wants to spend their time twisting and turning a portfolio every other page. Keep your horizontal photos together as best as possible, and your verticals the same.
There are many places that offer high quality portfolio books. Lost Luggage probably has the coolest, but they're expensive. Mpix has a really nice cheap book as well. I put all my stuff on mini-cds now, because I haven't been asked for a print portfolio in over a year:)
Hope this helps.
