These look fantastic. Is there any particular trick to not losing a lot of image quality when uploading to BlueSky? I'm only just starting to mess with CRT photography and the end results aren't perfect, but they get kinda mangled when uploaded.

Huh, not sure! These were uploaded from mobile uncompressed, taken by Varlens so I think they may be even bigger files than the iOS camera app. Sorry wish I could be more helpful!
