More Campfire Flames
Jul.07, 2008
I’ve become fascinated with capturing flames. This time I decided to experiment with shutter speeds and f-stops to both freeze the flame as much as possible while preserving depth of field. Took about 60 shots and some of them are quite interesting (more to come), especially at the higher shutter speeds (1/2000th to 1/4000th of a second). Haven’t decided yet whether the difference between what you normally see looking at a campfire and what the camera captures is because your eyes average the flames or the camera fails to capture portions of the flames. It’s probably a bit of both.
When I first looked at the pictures on my computer at home I was disappointed with what appeared to be a fair amount of noise in the black areas of the pictures, but for some reason it disappears once I process the raw files into jpegs. This shot was taken at 1/2000th of second, F/5.6, ISO 800, with a Canon EF50mm f/1.8.

Perfection! Difficult to meter as the light is constantly changing. At ISO 800, we’d expect some noise, but could the lens pick up smoke or heat radiating from the flame that is causing the noise?
By the way, I have the Canon 70-300mm f4-5.6 USM IS lens.

Thanks. Radiation would be a possibility. I guess one way to tell would be to take other pictures at same ISO settings in similar surroundings but no flames.
Nice lens, for sure better than my kit zoom. Maybe Santa will upgrade me at Christmas :)
