Thanks for chiming back in. That is really interesting. I hadn't actually heard of the Golden Ratio. But I looked into it and seems cool ( https://petapixel.com/2016/10/24/golden-ratio-better-rule-thirds/ ). It is interesting how a certain composition (rule of thirds or golden ratio) just seems more aesthetically pleasing. Thanks for sharing.Oh, don't get me started on the "rule of thirds", I don't like it. Gimme the golden ratio any day! Anyway, I'm not a big believe in rules - hence, using things like fisheyes and LensBabys. Honestly, I just like Bryan Peterson's way of thinking of it - the farther to the edge the focal point is, the more interesting, but the more it needs to justify being there. Different subjects should be composed differently.
I think you can get a good photo at a car show - but it's not all that easy. You won't get the glamour shots that VisualEchos does - they're beautiful but frankly I don't have the patience! But you can certainly get nice detail photos, and if it's not too crowded, you can get farther away and use a telephoto to isolate a car from anything around it. It's good IMHO to get low, too, which the telephoto helps with. For example:
You can also capture just part of a car. A short depth of field is definitely your friend. This was at the last LOG, shot with a lens that was built sometime around 1960:
If you want really short DoF, you need a fast prime. Here's a shot at F1.2, 50mm from a LOONY breakfast gathering.
Or, just look for some interesting part of the car and focus on that:
Everyone has their own style and ultimately, if you're not trying to sell your photos, the only person you have to please is yourself.
I do agree that you can get some really good pictures from a car show (and since I really like going to them probably most of my pictures will come from there). But it is impressive to see what types of results you can get out of the parking lot staged with a more interesting background.
An updated 50mm lens is definitely on my short list of new lenses. Canon has the really nice 1.2 lens but it is super expensive. Sigma a few year back came out with a 1.4 that has gotten really good reviews. I've also been considering the Canon 70mm-200mm lens to try out some shot at a higher focal length than what I've shot. But again, super expensive...
