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?

Hi John!
there is not Shortcut for Crop - Auto. isn´t ?

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.

I've read about the synchronize technique, but my understanding is that it adjusts the angle of the rest of the photos the same degree as the first photo, instead of recalculating the degree of straightening necessary for each photo. True or not true?

The issue is that I might have 2500 photos all taken against the same set of vertical columns, (in a stadium, as it happens) but each photo might be off by a slightly different amount and in a different direction. Syncing the angle of a bunch of photos to the angle of the first photo is not a solution, as the corrections will be different for each one.

Please advise.

I don't have the original NEF file. I convert everything to DNG on import. This morning I included the DNG file.

I wonder if this is a Mac vs PC issue. It's supposed to be the same code base, but differences can creep in.

I can't explain the phenomenon; I was hoping someone at Adobe might do. I just observe that this makes Transform useless to me.

Again, this photo is not an outlier; there were bizarre tilts and distortion throughout the collection.

I have customers waiting; I need to get back to doing post on this collection. I have a workaround that works. Hit "r", and punch the Auto button. Every. Single. Time.

Below is the result from the original DNG - I needed to Reset crop in order to see the whole image frame - with the Full option of Upright applied. I've allowed the white edges to remain below, to better illustrate what's going on with perspective straightening when that option is used on this specific exposure.

It seems that the prominent white wall behind, which was not photographed straight-on, has caused Upright / Full to distort the entire photo through a combination of transforms, to bring the top and bottom edges to parallel. That is not unusual for "Full"; it gets quite aggressive pictorially. This looks similar to your bad-result example, IMO.

By contrast, "Level" button in Upright leaves the image alone apart from rotating the whole thing as-is - exactly what Crop's Auto levelling button also does. The other Upright modes do additional transformations and I would regard Full in particular as very much special-purpose - for example, if photographing a painting on the wall of a gallery (where you only care about the squareness of that one 2D surface, and not at all about the wider perspective of the photo).

This DNG was behaving a little unusually for me until I turned on CA and lens corrections (which a tooltip in Upright recommends doing before it does its analysis, rather than after), and then cleared the crop that it had brought in initially. Then everything was as I would normally expect with a newly taken Raw coming from my own camera.
