AUTOMATIC HDR MERGE - BATCH - AUTOMATIC

Report · Mar 23, 2024

Hello during my weekly jobs, I have to merge more than 200 views in HDR.dng file.

My workflow is:
-Select 3 pics for each view from Bridge: Open in CameraRaw,
-Select All,
-Merge in HDR (mostly with ghosting off),
-Save,
-Close the Camera Raw,

-Repeat more than 100 times.

My question is.. there is some tool that works like that: (for example) I select with red labels every 3 exposures from each view, then I will have around 300 pics selected for example.
Next, I will select all the photos with labels click on merge to HDR.. and CameraRaw automatically will merge the pictures with the same point of view creating 100 different HDR .dng files?

This will be a game changer and will save hours from my time

Do you know some tool for it? Or maybe the Adobe Photoshop department is working on it?

Cheers! 🙂

I'm not sure if the following script will be suitable, it's not exactly what you are asking for:

Chai Stephen,
Thank you for your answer.

I m little bit noob about scripting.
How can I add it in bridge?

Report · Mar 27, 2024

It's a Photoshop script, not Bridge.
