compare my photograph (first image) with the version Bluesky serves users when they load it at full size (second image). It's fucked! They've fucked my photo. I worked hard to create and maintain my grit and they go and soften it. Unacceptable
(edit: you may need to zoom in on account of the lightbox shrinking the presented size with more than one photo here. or just open in a new tab to view it at 100% size)
Further investigation shows that in addition to recompression, Bluesky will fractionally downscale an image to 2000px on the long edge. It will also, bafflingly, fractionally upscale it to 2000px.
These example crops are upscaled 2x with nearest neighbor to show and preserve detail (since I was posting them on there).
In order:
- original (2.34MB, 1639x2049)
- Bluesky's downscaled and recompressed version of that image (494KB, 1600x2000)
- Bluesky's best-case version when given a 2000px crop to avoid rescaling (715KB, 1640x2000)
- Bluesky's bafflingly upscaled version (788KB, 1660x2000)
Cohost serves the original 2.34MB image unmodified (thanks to Cohost Plus!), and Twitter serves a visually indistinguishable 2.26MB version.
Not only is this not suitable for sharing my photography, it's just straight-up weird.
