Thanks for info Sid. and feedback kory!
Bangaz. i set up the tripod late afternoon. took a pic during natural light for grass and sky.
then waited half hour for it to get dark, and started taking long exposures painting the car contours with a little led torch. took about 20 pics all up, only used about 10 or so.
Just cut and pasted the parts i liked on top of each other then shifted the colour (car was blue from torch), and touched up the background to try and make it look as if it's real. Took ages, but i know i can do it now, so i'll try it again with a clean car and decent composition in the near future
