Tonight I got my new lenses and decided to play around some more with flash as I was taking test pictures. I am a complete novice when it comes to flash and now I'm trying to get used to RF triggers. I had the flash set too low, and got this very underexposed shot:
I was going to delete it but thought I would use it to see how much one can recover in the shadows with the K-S1. So I used Lightroom to adjust exposure and shadows, and came up with this (and yes, I know the background is pretty horrendous):
I was amazed that it looked quite reasonable. I was shooting at ISO 100 and the extreme lightening did introduce noise, but not as much as I had expected:
Here's a 100% crop, to show how much noise there was:
It cleaned up very nicely with a little bit of Topaz Labs DeNoise.
I'm really glad I tried this. It gave me confidence in the camera's ability to stretch the shadows more than I had expected. I'm not sure I could have gotten this type of result with the K3, though I routinely did things like this with the K5 (and had less noise). The photo was taken with one of the new lenses, the DA15.
