If you want to try that truck shot again with a lower iso and longer exposure, lets have some fun!
Got a speed light? Right before the end of the exposure pop a flash on the truck. It'll pop right out of the picture!
Need more fun? Have someone lie down in the truck (or stay up, your choice) start the exposure and right at the beginning of the exposure, pop that flash on the truck. Now get some friends and push that truck out of the picture while the shutter is still open and taking that picture, don't worry, they won't appear in the final picture, it's just like magic. The person in the truck is to drive, you don't want to open any doors, or turn on any lights. What you'll wind up with is a "Ghost Truck!"
No speedlight? That's ok, just take a flashlight and "paint" the truck from afar. It'll still show up real nice. Need more? Take that flashlight and walk it around the truck. As long as you don't point the light at yourself, you won't show up in the picture.
Most of all, just experiment, do the same picture over and over and over, delete the bad ones and have fun! It's what it's all about. :star:
Oh, and I just noticed this is the critique forum. Perhaps this would be better off in the learning / low light - night section.?! <---learned that from my daughter!
