All these images are exported from Photos.app on macOS 14.4.1 using the “Original Color Profile”. They are shot RAW with my Lumix. Has not been a problem since the April photo challenge
Anyone else having this trouble? I have no idea where to start troubleshooting this.
Bluesky has a smaller file size limit that was blocking photos from crossposting so I think Manton is now running some processing reduce the size of your images. This is almost certainly a consequence of that.
That’s probably it. Bluesky has a very low limit for images, just under 1 MB, so Micro.blog tries to resize it multiple times until it fits within the limit. I expect something is going wrong with the colorspace during that resize.
If you don’t mind running an experiment, next time I wonder if you export from Photos.app and choose the sRGB color profile if it makes any difference?
Apparently, if you post directly to Bluesky, you can have a larger-sized/quality image, but not via the API. This effectively makes sharing photos on Bluesky via API useless coz 1 MB is pitifully small. PNG graphics may be ok.
Even 1 MB often looks alright in my experience… obviously your milage may vary. I assume Bluesky will raise the limit. I think the issue that started this thread is more about the color profile than the size, but I’m not sure.
Longer term, our plan is to make Micro.blog a personal data server for Bluesky. When that happens, I believe we’ll have direct control over storage so we can remove the limit completely.
I usually only post 2000px wide smaller images to Micro.blog… but they could be going over the 1mb limit… this hasn’t really happened before, but maybe because I was using the iOS app?
I will test the sRGB profile tonight when I post to the challenge and report back
