Avoid Lightroom develop adjustment on images back from Photoshop

[bruno_4933]

Hi, 
I am working with LR 14.2 and PS 26.3 on Mac Mini M4 with Sequoia 15.3.1.

LR preferences are set to use PS as external TIFF 8bit image editor with Adobe RGB 1998 color profile (same profile is set in PS).
I import a RAW image into Lightroom, apply a user preset, export to photoshop, make some changes, save as TIFF and close. Returning to LR I find the TIFF image with a develop adjustment applied.

I have noticed that sometimes is the same preset of the RAW image, sometimes there is just the small develop icon in the bottom right corner of the thumbnail which seems no changes has been applied.

Is it possible to prevent LR from applying any sort of develop adjustment?

Do you mean the Develop Preset seems to be applied twice to the TIF? (Once in LrC and again when it returns from Ps.)

And after the TIF is 'Saved' from Ps, does the TIF in LrC show any develop steps in the History panel?  I see this in History-

And my TIF from Ps also shows the 'Photo Has Development Adjustments' badge-  which is apparently normal.

If you edit in LrC and apply a preset then [Edit in Ps], then indeed that develop preset is incorporated into the TIF that you are editing in Ps. (In the same way that a raw image edited in ACR and opened in Ps would show the ACR edits.)

Hi Rob,

it is exactly what it happens but, when the TIF comes back to LR, it has the same develop settings previously applied to its RAW version causing, in my case, unwanted changes to WB color, Highlights settings etc...

A mystery to me, and I don't have an answer. I cannot emulate the same in my system.

Can I clarify some of your statements-

"export to photoshop" -  DO you mean EXPORT, or are you using the [Edit In] command [Ctrl+E]?

"save as TIFF" - Do you simply [Save] and [Close] in Ps, or are you doing a [Save AS]?

Are you Importing the new TIF to LrC (either by normal import or synchronize folder)?

I note your screen-clip shows two images in "Previous Import" which is a little odd! It suggests you have (freshly) Imported the raw and the TIF also.

Do you have that preset named in the Develop Settings in the [Apply During Import]  panel?

So I don't have the answer! You can however, until you get a corrent answer,   do a [Right-Click] on the "Edited in Photoshop" history step and then [Clear History above this step].

When the file is open in Photoshop, go to File > File Info and look at the raw data tab for crs: metadata. These entries are the camera raw settings used by Lr or ACR.

A Photoshop script can remove this metadata. Test with care on a duped or non-critical file, I don't use Lr so I don't know if this will help or not:

// Remove Camera Raw Settings CRS Metadata from Open Doc.jsx

#target photoshop

removeCRS();

function removeCRS() {
    if (!documents.length) return;
    if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
    var xmp = new XMPMeta(activeDocument.xmpMetadata.rawData);
    XMPUtils.removeProperties(xmp,XMPConst.NS_CAMERA_RAW, "", XMPConst.REMOVE_ALL_PROPERTIES);
    app.activeDocument.xmpMetadata.rawData = xmp.serialize();
}
