In my quest to deal effectively with the rather large files from my Sony A7RIV, I thought I had an idea... first convert to dng, smaller file size, then to Photoshop.
The uncompressed ARW files are 117MB, when sent to Photoshop after working on them in Lightroom Classic they are 344MB. Then with layers they start to get really large.
I thought if I first converted them to dng with Adobe's dng converter, where they are smaller, in the 70-80MB range, import them into Lightroom, work on them and then send them to Photoshop that they would be multiplied by 3 or so, just like the ARW files, eg 210-240MB. For some reason, they come into Photoshop at 344MB, just like the basic RAW ARW files.
Am I doing something wrong, is there no free lunch here, can someone more knowledgeable than me explain this?
Thanks.
