Still says I'm using around 40 GB for my pictures. I thought it was unlimited and free for photos now. My camera is 16 MP. Don't know how big all my RAW picture files are.
If you go to settings, you can change it to "high quality" instead of "original". But I don't think it changes existing photos, so you'll have to manually delete everything and re upload.
Make sure you redownload the Photos auto backup program for windows, it's updated to support the new service. I selected high quality in it. So all future uploads won't use my space. Sucks there's no easy way to delete or compress the existing pictures. RAW images might still take up space though. So I guess I'll keep paying two bucks a month for 100 GB.
