Remove constant artefact from multiple photos

[Andrew22925299q4xx]

Thank you in advance

I'd like to have a mask or script or some process to repetatively remove a blemish that is in exactly the same place on every photo.

A few thousand of my several thousand photos have developed a vertical dark grey line a few pixels wide spliting the photo in half between the long edges

This developed a few years after I exported JPGs from Aperture on my Mac and reloaded the photos on a new Mac (its complicated)

It doesnt appear to be an inadvertant watermark because it is not present on all photos in a single folder, and some have been duplicated and only one of the pair has it.

It is also in the same position whatever the original orientation of the camera is.

How it got there is less important than getting rid of it!!!!!!

An example is attached

I am new to photoshop (or returned after a decade)

I have just started with the bundle of Lightroom, Lightroom Classic, and Photoshop

Thanks for your help

Photoshop vers 23.1.1

1) View / New Guide / Vertical / 50 percent

2) Single Column Marque Tool on guide

3) Select / Modify / Expand / 1 px

4) Edit / Fill / Content Aware

5) Deselect & Clear Guides

Make Action from above (that starts from opening a file, and ends by closing & saving it).

Then use 'File > Automate > Batch' item which you set basing on one of many tutorials 😉

I would have recommended pretty much the same thing as @Kukurykus – so here is a "different but same" method...

1) Start recording an action

2) Filter > Camera Raw Filter

3) Spot removal tool using heal, brush 2px wide, click once at the top of screen over the line, hold down shift and click once at the bottom of the line.

4) OK the filter

5) Stop recording

That's useful too.

I forgot to mention that this can of course be performed in the "proper" Adobe Camera Raw plug-in on JPEG/TIFF/HEIC files (as well as raw), with the setting synced to multiple images and the batch saved using the ACR save options.

[Kukurykus]

What do you mean by 'with the setting synced to multiple images', and what's the adventage?

[Stephen_A_Marsh]

When using the CR filter, one needs to record an action for use on multiple images.

The ACR plugin is different, one either has to sync or copy and paste the metadata settings over multiple selected images to share the "edits" (metadata instructions).

[Kukurykus]

If you mean doing it other way than saving it to action, show how, because I don't get it 😉

[Stephen_A_Marsh]

My ACR settings allow editing of JPEG files with/without settings, so I browsed the files and then used CMD/CTRL R to open them from Bridge into ACR.

The following 3 frame GIF animation shows the process of syncing the settings over all selected files in ACR.

Thank you for your help. I will sit down and give "both" methods a go, and see which give me less repetative strain injury!!!

thank you for your help and advice. I will sit down and give it a go

Actually, beside 'open', 'save' & 'close', only steps you have to record are middle ones: 2, 3, 4.
