Lua tuning of Advanced Auto Bracketing

We have discussed Advanced Bracketing before.

For me, as a Lua coder, it is a very powerful tool, however, it lacks finesse, as I have no control over it.

My latest scripting project is making use of the Auto Advanced Bracketing, but it is not fully meeting my needs.

As an example, if I start auto bracketing at a very fast shutter, eg 1/2000, the bracketing will stop when the shadow end is still very underexposed. I would say 2 stops at least underexposed.

Can I convince you to give the Lua coder (sic) a way to 'adjust' the auto bracketing, at least for the shadows?

Cheers

Garry

Found a hardcoded limit of 20 images (or 10 images if you select "0 - +", but the scene only requires adjustments in one direction). Are you reaching this limit?

If not, I'd like to see some sample images.

This is not about image taking limits.

What I see is the shadow end bracketing is too low for me, ie by a stop or two.

That is I want is to be able to position the shadow end to be more in ‘mid tones’.

I’ll gather some ‘test cases’.
