Exporting JPEG images from Apple Photo

[Bigbamboo]

Despite selecting the High option when exporting JPEG images from Photo, I find the file size at destination is usually around 3MB - approx 60% smaller than when I exported the same images from iPhoto with the High option. If Photo is compressing JPEG images more during export than iPhoto, I assume the image quality is also reduced. Worse still, there is the possibility that Photo is actually extra-compressing images at the import stage, not during export. Or both!

Has anybody noticed the same issue and, if yes, does it also apply to TIFF and PNG images?

It has option to export unmodified original, so no compression on import is performed.

Thanks, but my query concerns exporting modified images. Curiously, since posting, Photo's export dialogue box has started showing a 'Maximum' option which is the resolution I was looking for. During the first week of using the app, this option was not available! So, problem solved. I also had a problem with Yosemite's Mail app, but this self-resolved, too.
