Guided Transform does not synchronize correctly on selected images

[keptlight]

This may or may not have been discussed but I have not been able to locate the problem on the forums. Here is the situation:

1. I have three images, exposure bracketed for merging to HDR
2. The HDR merge process works fine and I now have four images that can be superimposed perfectly, you will see the examples
3. I highlight all four, select the Guided Transform tool and draw one vertical line
4. The two other camera exposed images show the exact line but the one that was merged to HDR has a horizontal guideline at the bottom!
5. As I continue and add another guide on the left side of the camera image, the HDR version puts another horizontal guide at the top!

I am writing this post partly from curiosity and partly in case this is a bug.

Here are the original images, then the HDR and followed by the screen captures with the guides. :

Here is the HDR merged image

Now the guides, I will use only one of the original photos to save on presentation length and add the HDR version as well for each guide

The HDR version, note the guide at the bottom at an odd angle

Here is the second guide

And, the HDR guide placement in the sky and the strange transformation

My knee-jerk reaction is Adobe did not attend this, but look at what I found via a goggle search:("lightroom guided transform batch")

How to correct distorted horizontal and vertical perspective in photos using Lightroom CC 2015.6

and that leads n=me to searching on "lightroom guided transform Copy or sync Transform settings "

Link I already provided is top most result.

and similar but quicker to the point

Syncing Upright Transform Corrections in Lightroom CC « Julieanne Kost's Blog

Thank you davidg. The problem is not that the transform tool does not work but it fails to synchronize only on an image merged to HDR in Lightroom. All three are perfectly synchronized in perspective correction. In short, what I put as a vertical guide becomes a horizontal, and vice versa.

It is not a big deal to do them separately, they will be only pixels off if any. It made me wonder if the HDR merge may have changed the internal image information as if it was rotated. Who knows!

Hi,

I have no idea if there is a 'bug' but- Even if the Transform tool can synchronize multiple images, I doubt TBMK that the transform edit to the individual files is carried over to the HDR that is created.

I suggest- create the HDR first, then do the transform on the HDR only.

Note below- 'Upright' is cleared for both the HDR & Pano

The following notes are quoted from Rikk Flohr and might explain-

HDR/Pano Settings

Please note that the settings that are copied over will differ between the HDR and Panorama cases.

For a Panorama, the merge tool is changing geometric attributes, and will therefore not copy over existing geometric settings such as Lens Corrections/Upright (with the exception of Defringe settings).

For HDR, the merge tool is expanding tonal range, so existing primary tone settings (such as Exposure, Contrast, Highlights, Shadows, Whites, and Blacks) are not copied over.

Settings cleared for both the HDR & Pano cases:
- Local Corrections
- Red Eye
- Upright
- Crop

Settings that are copied over (with some exceptions):
- Basic Panel (except primary tone adjustments for HDR)
- Tone Curves (HDR no, Pano yes)
- HSL/Colour/B&W
- Split Toning
- Detail Panel
- Lens Correction (HDR yes, Pano only Defringe)
- Effects Panel
- Camera Calibration (except Process Version, which must always be current for HDR)
- Spot Healing (retained for Panos only)

Thanks, WobertC, for the detailed response. I am aware of the transferrable adjustments from standard images to pano and HDR. But, I will mark this as a bug and move on. If Adobe wants to do something about it, that will be fine. There may be something that is changed in HDR merge that is not documented for the users. But, I surely can live without this feature. The physical dimensions of all the images are identical, so are the orientation.
