P: Sync Auto Straighten and recompute the angle

Hi,

It's a simple request and an enigma, why it hasn't been done yet. When Syncing a settings of a photo, which has been automatically straightened, just recompute the angle for every synced picture.

Make it selectable / deselectable in the sync menu.

@Bronte27471200xxe5: "Being able to batch straighten instead of having to go into the crop panel on each individual image would save so much time for large galleries."

 

See here for how to batch straighten:

In the crop panel, there is an 'auto straighten button'. Which automatically straightens the image

It would be super helpful if you could add this to into the library quick develop section, so we could apply this as a batch edit. Being able to batch straighten instead of having to go into the crop panel on each individual image would save so much time for large galleries.

Thank you very much! I didn't knew that. And you can also use the feature from crop "constrain to image". That's quite nice.

 

Even though, there is a workaround for me now, I feel a lot of people might not find it and don't make the connection with "Transform" Panel and only select "Upright Mode" while syncing all images.

 

I think as well, that all automatic configurations the Transform panel does, should be visible to the user. For example: Which angle was applied? Was has it been zoomed in? Etc. It doesn't apply for only a the Level feature, but every feature in the Transform panel.

Thanks again John.

"t's an auto straightening / level feature, which it is not. It just applys the same changes from one picture to the other without estimating the level."

 

When applied one photo at a time, Transform > Upright > Level computes the same straightening as Crop > Auto does.

 

Unlike Crop > Auto, you can apply Upright > Level to a batch of photos, and LR will recompute the straightening for each photo.  You can do that with Auto Sync, but if you do that with Sync, Copy, or a preset, however, you must be sure to check Upright Mode and uncheck Upright Transforms and Manual Transforms:

 

 

"Import the files and apply the level feature. It didn't work for me."

 

You likely had Upright Transforms checked.

 

See the bug report for the extensive testing I did with all the methods of applying Upright > Level.

Hi John Rellis,

I already read about this feature. It might be the same algorithm, but it is handled differently. On top, you cannot see, what the algorithm does behind the scene (What angle did they use?)

This intransparent behavior also leds people to believe, that it's an auto straighening / level feature, which it is not. It just applys the same changes from one picture to the other without estimating the level.

Just do a simple test: Take several pictures of a scene and rotate during this your camera. Import the files and apply the level feature. It didn't work for me. My observation probably goes hand in hand with your observation (2. paragraph).

Transform > Upright > Level uses the same algorithm as Crop > Auto.  You can apply Upright > Level to a batch of photos using Sync, Auto Sync, or a preset (via Library's Quick Develop panel), and the angle will be recomputed for each target photo. 

 

Unfortunately, applying Upright > Level in batch often produces different results than applying it individually.  Sometimes the differences are minor, sometimes quite noticeable.   

 

See this bug report I just filed:
