4 hours 10 minutes
Well, today's post is not artistic per se, but I loved to share this experiment. I hated to waste the image here and it was a subject of some experimenting.
As the title suggests, this shot is a long exposure for 4 hours and 10 minutes, done inside my car few days ago. I was hoping to capture some trails of lights, but I didn't get much except for the terrifying level of noise!
The top image is the original, and the bottom one is after some trials of noise reduction in various methods (I think I've done 2 or 3 iterations here using various techniques). The noise level in the original might be not much because of the small size, but originally, it was a measles-inflicted image!
What bothered me the most here is that my approach to use a "dark frame*" failed, and the technique didn't really change anything concerning the noise level. Thus, I had to do things manually on various levels to reduce the noise. The final outlook at the bottom is muddy after all of that and still contains some level of noise, but I think at this zooming level, it is somewhat acceptable (but not to be printed!).
Anyway, I just thought of sharing this experiment instead of wasting the experiment away. Maybe someone would find it useful in some way.
