Inaccurate JPEG file sizes, the estimated file size and the actual file size are a long way apart - e.g. estimated approx 18mb - actual 34mb
Alamy uploads struggle with anything larger than 20 - 21mb, I have contacted them too as on one hand they ask for quality and the only way to upload is knock the compression up.
Two things in Capture one, it would be nice to have the esimated size a bit more accurate, and it would be useful to be able set this as a target in a recipe.
I'm having to export JPEGS to open them in Affinity Photo which gives an accurate indication and resave the files.
