P: Better auto stacking for bracketing, HDR, Focus Stacking and Panoramas

I currently shoot a lot of Bracketed shots for exposure blending, and with each shot having a different shutter speed the auto-stacking can fail to accurately stack the grouped shots - especially when the shutter speed gets up into 10+ seconds!I would love an option for Auto Stacking to work on the time delay between the shutter closing and the shutter opening again, so it is a true measure of the gap between shots. In this way I can auto-stack on all bracketed shots even when the shutter speed is seconds long. Calculate the time between shots by adding the shutter speed to the capture time of the first shot, and then compare this to the capture time of the next shot, and if I am using Continuous shooting, this gap will be only a fraction of a second, regardless of the shutter speed.Gary

I have customised a Bridge script that stacks images correctly using this method.
It compares (gap between images - the duration of the first shot).
As you proposed, this proves more reliable than just working from the shooting timestamp of each image.

The problem is that the stacks (groups) created from this scripts don't process correctly with Adobe's "Process Collections" command. So I am working on my own new script to process the HDR image stacks.

truthfully at this point, I'm tired of waiting for an automagic solution (whether it's plugins per my link above, or sub second/multisecond intelligcence) I'd settle for a simple "stack by N..." function that takes all the selected photos and turns them in to stacks of N (most often 3)

I agree with Bryn. I have shot over 20 panoramas in manual mode with everything fixed (white balance,shutter,ISO,white balance,zoom,color profile). This produces from 28 to around 70 photos if I shoot HDR,

Photoshop has never successfully identified and autostacked any one of my panoramas.
It usually fails by grouping too many / too few exposures.
It fails even if the folder contains a complete set of panorama shots, nothing more and nothing less.

Option 1: Give us manual control so we can tune the timings, brackets to make it work
Option 2: Do more testing and make it work reliably
Option 3 support 3rd party plugins that work well.
Option 4: Let us modify / correct errors in autostacks manually.
Option 5: Add a batch HDR function that operates on all stacks in a collection/folder so we can skip "Process collections".

Or a combination of the above.

Also for the opposite, I'd like auto stack to work to work when shooting hdr sets quickly (I shoot HDR panoramas, with a 10fps camera and often get 1 and a partial set in a second so I end up with stacks that are 4,2,4,2 and so on)
I think it'd be better to allow stacking plugins

which could then take in to account exif flags like the ones canon puts in that says it's part of a bracketed set, and any other creative ideas people have automatically group pictures together.

Seems simple enough, and useful...
