Hi,
I have a question about telephoto lenses. I like auto racing photos taken with 600mm lenses, I like the compression of the car. I also like to photograph scale models of race cars and composite them into background photos. My question...what length lens will give the same compression of a 1:18 scale model of a race car as a 600mm lens gives for a full size car? Do I need to use a 600mm lens to photograph my 1:18 scale model, or a different focal length?
thanks
brh

Hi brh. Focal length compression is pretty much determined by how far away you are from the subject of the photo. If you can provide some more details about the circumstances under which you will be photographing the real life and scale model cars it might be easier to help you  |

Hi brh, welcome to PSE&M!
I can't help you but one of our members, billz, may be able to. I believe he has extensive experience in this kind of shots. I will bring this thread to his attention.

Hi brh -
Sepiana may be overstating my expertise here, ;-) but fstop's answer was correct. It's a matter of how far the camera is from the cars out on the track.
I would think though that the longer the macro lens, the better for your the purpose of showing compression. Maybe start with a 105mm and see how it goes. I've never tried a teleconverter (or extension tube) with a macro, but that may help things even more. I hope to see how it all turns out.

Hi,
Thanks for the replies. I take photos of cars on the race track with 300mm lens, then composite in a photo of one of my 1:18 scale diecast cars. I have been using my 105mm macro when photographing the diecast cars, the image of the small model car fills the screen. I'm wondering if I need to worry about any lack of compression in the photos of the diecast cars.
From reading more about telephoto compression, and the replies I got here, the compression is determined when I take the photo at the racetrack. As for the diecast car photos, I'm not sure I need to worry about 'compression' of the car photo at all -- and I can
always use free transform in PSE to adjust the image if needed. Perhaps I'm over-thinking this issue.
--guess I can't justify needing any new lenses!
thanks to all
brh
