Whoa!!!!! man its fun and I for some weired reason never tried doing light painting. We had hard time painting with torches and flashguns, but it was AWESOME!!! First few days were awful, because we couldn't get to the location, and it rained Dinosaurs & Godzilla (in comparison to cats & dogs). As we sat together cursing the weather in whatever language and words possible. I went a step a further and tried some indoor light painting, which was not what the assignment said, so didn't actually accomplished my own project.
Ultimately we found some spot for our light painting and we did just about fine. I tried something, sort of horror. The camera was put to a test of combination of long exposure and high ISO. The only problem of Digital SLR is they have everything integrated and its in a compact body. The battery is there and sensor runs on electricity (supplied by the battery) so when you are doing the long exposure, the sensor is working because its continuously registering images unless you end the exposure. So for this continuous work, the sensor gets heated up and its gives noise. so for longer exposure there is noise, however, for some reason I didn't have noise at all (according to me a very little noise is negligible in this case). One possibility could be that it was cold and secondly I used only 8 second exposure. But need to research on this a little more.
