A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

DNG files - large size and small resolution (alien.top)

Hey,

I took a couple of thousands photos with my DJI Mini 2 in the last couple of years. In almost all cases, I used its raw photo shooting mode which saves the photo both in .dng and .jpg format. I stored the files locally syncing the folders with OneDrive, then moved to iCloud Drive as I was changing cloud service. I stored all files online only.

I've just noticed that all the .dng files resolution became 960 x 540 pixel but its size remained the original, that is 17.7 - 18.5MB. The photos saved in .jpg are fine, 4000 x 2250 and 4MB.

What happened to the raw pics during all these moving and transfering over time? Can I recover the original .dng shots somehow?

Raw formats also usually save a smaller resolution preview image of the photo within the metadata, so that there's something to show about the unprocessed raw data. It's likely that whatever OP is using to view the photos are only dealing with the preview.

I opened the file in Lightroom, it worked well. Original size and resolution.
