Stacking
(Highway 395, California) - This image was created from 26 images stacked in PS5. 25 images of 4 minutes each (yes, that is 100 minutes or 1.40 hours of exposure time!!) were used for the star trails. I did two light painting exposures before starting the series of 25 images. I blended one of these in to emphasize some of the details on the cars a bit more (the headlights, grills and some detail under the hoods).
Did I just sit around when doing this? No, I was using my 5D Mark II to shoot other stuff while the 7D was taking this image. Why the 7D? I managed to horribly smudge my second 5D with an inept application of the Arctic Butterfly cleaning utensil.
I just took a guess at where the star trails would go, but I knew this was roughly North-east so they would curve the same direction as the hoods.
