I like to take portraits in low light. My T5i doesn't have an incredible sensor for low light, but my F/1.8 lens helps get more light. Still, if the conditions are too demanding, I need to turn up the ISO too high and I get noisy pictures. I've got a few ideas and I'd like to know which would be the best technique to get better photos.
- Median stacking - I've seen this used in landscape photography where multiple properly exposed but noisy exposures are blended into one and the noise is removed. I don't know how practical this would be since the subject is subject to movement between each successive photo.
- Exposure stacking - My camera has a setting where it takes 3 consecutive underexposed photos at 1/60s and combines them into one brighter exposure, but it doesn't work too well because 1/60s is too slow of a shutter speed for me. Perhaps if I shot faster, took more photos (say 5), and combined them manually in Photoshop they may turn out better.
- Shoot a single photo at high ISO and suffer the consequences of noise
Before you say get a flash, I like the natural look you get from just the ambient light and even if I used a nice flash that's well diffused I can still tell that a flash was used. Are any of these options preferred, or is there an even better option/technique out there?
