Grab shots
Stefan
Re-inventing the wheel? Almost certainly so, but I don't recall seeing any recent posts on the subject.
You and Jkarpin2 set me thinking about that 'automated' setting for grab shots.
Today in good but variable light in the garden I tried:
* Shutter speed priority
* Auto ISO
* Focal length 1200mm
* EV Bracketing set at +1 to -1
* Jpeg (SL quality).
That way I set the shutter speed to choice, and the only adjustments I may have to make in shooting are to change shutter speed or EV figure.
I chose a shutter speed of 1/125 sec and EV 0. I stayed with 1/125 sec, and only had to change EV 0 for a couple of shots.
I am not an experienced photographer. I guessed at half a stop latitude in post-processing for the EV bracket setting. That covers my most frequently used settings: -4/3 for bird against darker background, and +4/3 for bird against sky, and gives me a little extra either way.
I normally shoot in RAW, but I don't bother about white balance coming out wrong in Jpeg because Canon DPP offers a 'Click on White area' tool to correct white balance for Jpegs as well as RAW.
However in RAW I found that a burst of three bracketing shots took too long. When I miss focus, I want to be ready for my next crack at nailing focus as quickly as possible. Plus using EV bracketing to avoid the need to set the correct figure for compensation means you don't want the bird to have time to strike three different poses.
Result: In good light shooting at 1/125 sec I was happy with the ISO and aperture settings that the camera chose. I miss RAW though -- It's pure prejudice because I only occasionally think that I have saved a shot by post- processing in RAW: and I may not be right!
I attach best shots from a half hour session.

I'd like greater bracketing speed, but I'm not yet ready to compromise on Jpeg quality
