Are changes to dng images take into account ?
« on: October 11, 2018, 01:39:31 PM »
Hello,

Changes to dng images (like contrast, exposure, etc.) are written directly into dng files.
Are changes to dng images take into account by Photoscan ?

The changes are not visible in the thumbnail view, that is why I ask the question.

Thank you.

I have the same issue. Attached are two clips from the same DNG file. The first is what it looks like in Photoshop & Lightroom: exposure is quite good. The second is what the file looks like in Metashape Pro: exposure is blown out.

The photo was captured as a Sony RAW file, imported into Lightroom where Auto Tone Control was applied, then it was saved as a DNG and imported into Metashape.

Is Metashape ignoring the change to the tone curve? Is it able to use the detailed tone information in the DNG or is it attempting to process the "blown out" overexposed pixels that we see in the file as viewed in Metashape?

I am looking for the same answer. Anyone know how Metashape handles DNG image data?

Hello,

Metashape is not treating custom color profiles in DNG, so if you are applying any external color correction, it is recommended to save corrected images to TIFF or JPEG format.
