When the night comes, I cannot sit still, the years have not been so kind to me. There's a time and a place for understanding, and a time when action speaks louder than words. When time like the pyramids has worn away all the mountains and the valleys of the words that we say. We must make sure that something remains. If we lose ourselves we've got no one to blame. ---------------------------------- 30 second exposure @ f8 Nikon D1X Nikkor 28mm Ventura, CA - 2007
With digital cameras - especially ones with CCD sensors and not CMOS (which is the dominant technology these days) color in a long exposure becomes over saturated. These older cameras required enormous amounts of energy to hold a shutter open for this long and as a result you'd often get odd artifacts from fluctuations in the amount of power going to the sensor. With film you have a whole different issue called reciprocity failure. It has to do with the rate of exposure not being constant but on a gradual curve. Meaning a long exposure that should be properly expose at 40 seconds - depending on the film stock - might actually require 45 seconds. The further you stretch the exposure - the further the distance between the stock's absolute exposure value and reciprocity failure value grow. Reciprocity failure can result in some really bizarre color artifacts and exposure anomalies. The reason I mention this is because the odd color splotches in this photo are similar to what you'd see with film that experienced reciprocity failure exposure issues. Cross processing - taking slide film and then developing it in a negative process - instead of a reversal process - can also create these surreal color anomalies. Fuji stock is great for cross processing. You get all kinds of odd colors and exposures out of it.
Great capture; I need to do more experimentation with long exposures! Is the color in the sky due to the neon lights, or something else?
@JonPatrickHyde You have just taught me so much I didn't do :) I use a digital camera now, but I only briefly studied using film cameras in high school, so I had no idea that these kind of effects can happen. I think @hunahuna has some interest in long exposure photography as well; he might want to check this out! It's kind of awesome that you don't necessarily know what is going to come out on film when trying this, but that there might be affects that make the piece a bit /more/ that weren't planned for.
