Helpp needed on what mode and settings i have a mono pod an a tripod aswell

low light settings.

yeah meguairs motor expo

No no, i mean use general low-light settings. Wide aperture, high ISO and low shutter speed. Nothing trick about it. If you're keen get a hot-shoe flash and bounce it on innocent show-goers faces to keep things as sharp as possible. I wouldn't think a monopod would be allowed in and DEFINITELY NOT a tripod.

Rent a fast, wide pro-spec lens if you don't have anything of that sort in your kit. 50mm f/1.something probably wont be wide enough, especially on a crop so rent say a 24-70 f/2.8 or something along those lines, wider more-so if you can. If not use IS/OS/whatever on a wide lens set as wide and open as it can be.

How's that? Nothing tricky about it at all. Issue is, if you have a low-end SLR you're high ISO images are going to be balls because noise will kill it. D200/40D+ should be sweet though on say ISO600, 2.8 1/80th or so..

These days shows are usually fairly bright so if I was you, I'd aim to keep my shutter at 1/100th and then adjust ISO and set aperture to f/4 if you can, that will allow sharp end-to-end car shots, sharp lines and low enough (hopefully) noise. Sacrifice aperture for ISO though (as in, if you're aperture is on f/4 and ISO is on 600 drop your aperture to f/2.8 and drop your ISO to 320 for e.g.)

Oh and after a look at your blog, get a CPL too.

thanks for your time and knowledge guys like you i respect who share info with others

It's all good man, and in the big scheme of things, i'd probably be the least knowledgeable vs others cruising boost. Things like this though, is something you really have to figure out once you've hit the place you're going to shoot. Use your camera's meter and adjust accordingly and most of all, test shoot - review -adjust -reshoot. that'll garuntee you with shots that you're happy with rather than blind trust in what someone (say me for instance) has told you.

An easy method to implement what I told you above is to put your camera in Av mode (so you only control aperture) and make sure it's as wide as possible, set your ISO to something like 400 for a starting point and meter the car, see what it sets your shutter speed too and adjust your ISO up/down if you need too. Just watch for camera shake (keep above 1/80th as a rule).

This stuff should be automatic, the stuff that's harder to get right is composition, making sure you've framed it as well as you could have, making sure that you don't have distractions in frame etc.. being really aware of what's in the shot is harder - especially in a busy joint like a car show.
