Interesting idea Thomas! I like the auto part theme with the gearbox component in the background. I think perhaps your background needs to be a bit brighter though. Worth either adding extra light or trying a lighter colour.
One downside though I've found to having anything other than a plain background is that extra background detail eats up memory, and you can run up against the 60KB limit very easily. Hence you have to reduce image quality further to bring it under the limit and this means you have a less sharp, less detailed picture of the car. :cheers
It's a good idea. The only thing is that you can't make it more important then the primary object you are photographing. So maybe you should do it but with a little less lighting for the secondary object, or maybe even keeping it a little out of focus. It's quite hard to do, since you will have two objects to worry about lighting and focus. But properly done the result is fantastic.
That's a really good idea Thomas. I tried to bring up the brightness of your car and sharpened it up (& not the gear) to see if I can make the car stand out more. With a little photoediting, it is possible I think.
