Question

Any way to filter/sort by exposure compensation?

I've been trying to do this for years and thought I'd ask again - can you filter/sort by exposure compensation in Bridge?

I don't see it listed as an option in the filter panel. But Bridge knows the EV value for each image because it displays it in the metadata panel.

So.... can I sort by it?

Thanks

I had a hunch that it might have to do with HDR.

I think I have a solution but that's only if the exposures were taken in succession. That is: -2, 0, +2; then -2. 0, +2; etc. If that's consistant than you could set the Content Panel to three wide, then quickly Command/Control-click on all the middle ones. Then give them a colored lable and move to the next group.

Something like this:

But then another thing I can point out is that this could become much more automated in LRC. Once imported you can stack them via time between images. Then select all of the stacks and process them into HDRs while you go have lunch/dinner/whatever. However, due to the quantity, I'd be inclined to bring them into folders of multiples of 3 (300, 600, 900, etc.) And process them in such groups.

The thing I am perplexed on is why you'd make alterations on the "mid" image prior to compiling the HDR. Have you experimented on doing this? I asked because I did some experiments on this over 10 years ago and if you did make a change in one of the images, you have to save all three out as TIFs (or JPGs) to lock that change in. Otherwise, the software will ignore what you did as it will look at the "prior to your interpretation" of the raw data as opposed to the changes you made.

Let me know, I'm curious

Yes, they are always in the same order. The better way to do that is to click and drag each column.

The problem there is that Bridge doesn't sort by date correctly when you get 500+ images in one folder. So that approach doesn't work, or at least requires more attention than just clicking and dragging. But even then Bridge won't let you click/drag across the whole column. It selects a couple dozen then stops scrolling. So then you hit shift and click/drag again and it again stops scrolling after a few dozen. And then you accidentally click something else and your selection goes away and you start over...

It's equally tedious.

Regarding changing the mid, not sure I follow. These are landscape HDR sequences at sunrise/sunset. The lighting is changing and I adjust exposure to adapt. The "mid" image is the baseline; the over/under change along with it but stay at the same relative exposure (+/- 2 EV).

What about using stacks?

In Bridge, you can filter by:

You can Sort by:

So the answer is (unfortunately) no.

Can I ask what your objective is? Maybe there's another way around to get what you want?

Yes - that's what I thought. Alas.

Regarding what I'm doing, I do HDR timelapse and need to separate the images by exposure compensation (mid/over/under). I change the exposure for the "mid" image during the timelapse for sunrise/sunset sequences so a given exposure time might be a mid, over or under depending on where in the sequence it is taken.

So I have to filter for a specific exposure time then manually sort the mid/over/under for each exposure time. With 2000 images in some sequences that takes a lot of time and is *very* tedious work.
