Very nice work. I haven't yet tried shooting video with the K-70 but, as
a radio engineer (and former TV engineer as well) I need to start
thinking about getting good audio. What microphone were you using? I
wouldn't expect the mike in the K-1 to have that much high-frequency
response or to yield that relatively low a level of background noise.
Nope, that was the internal mic. I wasn't really trying for top quality
video, I just wanted to grab a cute clip. The sigma 20/1.8 despite it's
many faults, focuses nice and close (1:2 mag). I expect that the low
background noise is simply due to inverse square law, it being a short
lens, the camera was only a few inches from the baby birds.

I've been meaning to ask you about this. I was trying colored filters a
bit when photographing bands, trying to keep the red channel from
clipping. However, I wouldn't think that with headstones, the light
balance would be so far off that you couldn't get the same effect just
by tweaking the various channels in the raw files. Especially since
Lightroom allows you to use separate curves for each channel. With up
to 14 stops of dynamic range in your raw file, there's a lot of room
there for adjustment.
