Batch Auto-straightening isn't working

Good morning! I'm trying to auto straighten a bunch of photos, something I haven't had issues with in the past. I select my images, select 'auto sync', go to the crop tool and hit Auto to straighten. All of my images look like they've had an adjustment made (or LR thinks they have) but if I go back into the image and hit the auto straighten, more adjustments are made. This is frustrating as this used to work, so I don't think it's my technique. Any ideas on how I can make this functional again? Anyone else having this issue? TIA.

When you click the crop tool's Auto button, Auto Sync copies the computed crop angle from the current photo to all the other selected photos, so they all end up with the same angle. It does not recompute the straighten angle for each selected photo. I verified this behavior in LR 11.3.1 and 10.4.

To batch-straighten all the selected photos, computing the correct angle for each photo separately, do this instead:

1. Select all the photos and go to Develop.

2. In the Transform panel, select Level and Constrain Crop.

3. Click the Sync button and select Upright Mode only:

And yes, you could also use Auto Sync, but it's dangerous, and for too many people, using it eventually ends in tears.

2024. Still paying a premium subscription price and Adobe can't give us the ability to batch correct.

@craig.carmean, see this post for how to automatically level a batch of photos:

Good day! I found this solution earlier this year and it had been working great for months. but then recently after these new updates, it hasnt been working right for each image any more. Is there a new solution or something I should be doing now?

Hmm, I just retested my steps above, and they worked in my test catalog with LR 13.0.1. Do Help > System Info -- which exact version of LR are you running?

I'd like to suggest an enhancement request. There's currently no way to auto-straighten a batch of photos. Auto-straighten sometimes gets it wrong, but it would still be a net timesaver. I deal with thousands of photos over multiple days, and the single most common buttons I press in Develop is "r" followed by clicking on the "Auto" button. There doesn't even seem to be a keyboard shortcut for auto straighten, which although not ideal might be faster.

Ideally, I would Select a bunch of photos, click "Auto" once, and have them all auto straighten, NOT to the same tilt as the first photo, but each straightened as if I did it individually.

There already is a way to do this, even more than one way. The first way is to select the photos, go to the develop module, toggle the little switch of the 'Synchronize' button so it changes to 'Auto Sync' and then click that 'Auto' button to straighten. The second way is to save auto straighten in a preset. Save only the Transformation mode, nothing else. The third way is copy/paste, where again you should only select the mode.

@Melda, very interesting, I hadn't noticed that before. It looks like LR considers Constrain To Crop to be part of Manual Transform (those are the sliders in the panel -- Vertical, Horizontal, Rotate, etc.). So if you sync both Transform > Upright Mode and Transform > Manual Transform, Constrain To Crop gets copied.

If you don't want the Manual Transform sliders to get copied for some reason, there are two other methods.

First, I've attached a preset "Transform - Level" that I manually edited to include Constrain To Crop. Save the attachment to your computer and in LR, do File > Import Develop Profiles And Presets. Then in Library, select the desired photos, and then do Quick Develop > Saved Preset > Transform - Level.

Alternatively, and I don't recommend this, you could use Auto Sync:

1. Select all the photos.

2. Go to Develop.

3. Click the toggle on the Sync button in the lower-right corner to turn on Auto Sync.

4. Click Transform > Level (or another mode).

5. Click Constrain To Crop.

6. IMPORTANT: Turn off Auto Sync.

I don't recommend Auto Sync because it's dangerous and sooner or later you'll poke your eye out. Too many reports here of people forgetting to turn it off and not noticing until too late.

@johnrellis,
Thank you very much for your patience and the working solution – the preset you provided finally does the trick!

I actually found this thread via Google after struggling to batch auto-straighten horizons in large sets of landscape/seascape photos. At first, I naturally tried using the "Auto Angle + Constrain to Crop" option under Crop > Straighten, but as I discovered, that method doesn't synchronize properly across multiple photos.

Fortunately, the Transform function combined with your custom preset works exactly as needed – each photo is leveled individually and cropped correctly. This saves a huge amount of time.

Much appreciated!
