First post from a long time lurker.



When I upload jpg files from negative/transparency scans I find that the uploading process takes much longer than native digital files - even when they are approximately the same compressed size.


Is there any reason for this and can I do anything to remedy it?

Thanks. Yes the scans from film are generally larger, around 10mb when compressed.


That is because the jpeg compression algorithm sees a lot of fine detail (even in clear blue skies) from the film grain. WIth digital that sky would be an even tone so will compress more.
