All my raw files are converted to DNG in Lightroom for consistency and smaller file sizes. I made a copy of a dng when sending to Photo Ai, but on returning to lightroom I noticed the file size is 4x larger. This removes one of the main purposes of using DNG files. All I did was remove some minor noise. In this state it’s unusable
Steps to reproduce issue:
Launch Photo AI plugin from within Lightroom Classic 13.0.1
Photo AI removes small amount of noise, then image sent back to LRC
Check file in folder and file size is 4 times larger than it was. This is a major issue.
The DNG output file size is expected behavior. The original RAW file is likely compressed while our DNG export is full size and uncompressed so the output file is larger.
We do not have access to a DNG compression algorithm as that is proprietary to Adobe. If you need to decrease the DNG file size, use Adobe DNG Converter to compress the DNG file to a smaller size. https://helpx.adobe.com/camera-raw/using/adobe-dng-converter.html
Note that there is compression available in Photo AI for DNGs … but only as a standalone. A DNG will always be overwritten when used in plugin mode as you are doing.
I’m not sure when you received that reply from support but ask if they will apply compression to DNGs used in plugin mode as well as standalone.
