Hi all. I did a quick search about this subject and did not find anything useful for my situation.
There are several upcoming car shows. Most of the shows are inside a huge convention center. I am somewhat prepared for the events and got some ideas to play around and experiment with. I'll be mostly using my Tamron 17-50mm, tripod, shutter cable release, and a polarizer to take shots of the cars.
What I'm worry about is when taking shots with models in it. I'm thinking I will have to use my external flash unit but I'm really confused on the subject of using flash. I probably want to use some sort of diffuse lighting whether it comes from light bouncing off a wall, a type of diffuser, or any other techniques to diffused light. If I had to bounce light, then I would be in trouble since I'll be in a very large open area and bouncing light would seem impossible. So is my only option is to use direct flash? I do have "abetterbouncecard", a generic flash card, and a stofen cup. Is there a way I could use these to produce good shots? Also, I'll be shooting among other camera users so I probably be switching to my Sigma 70-200mm to get the half body and face shots. Oh, I have a feeling I'll be shooting in protrait mode most of the time so that would effect how I would use the flash unit. And another thing is if I do want to take a shot of the model in front a car, I'm worry that the flash will cause a huge reflection off the car.
If anybody has any tips for my situation, that would be great. Also, tips in general would be helpful to. Any information I gather will help me try new things out and learn while having fun
