Dusk in Austin
All these were shot using a Minolta 58mm f/1.2 on a Nex 5N. All shots were handheld and all images are straight from camera. No PP adjustments at all. DRO, ISO and AWB all set to auto.
My (amateur) technique is:
1) in Shutter mode, set the shutter at 1/ 160 to minimize handshake.
2) dial the manual aperture ring down until the LiveView image unnaturally darkens; then back the aperture off about 2 stops, so that the image is still pretty dark and the sky isn't blown out.
Using this technique, the Auto ISO will sometimes drop from 3200 to 2500, or even 2000... ISO settings that (I believe) cannot be specified manually.
I'm pretty satisfied with the results from this technique for shooting at dusk... but I'm sure many of you will see shortcomings to this approach, and evidence of those shortcomings in the photos. I'd like to hear how to do it better!
