Hi, got to this site searching for books on my GFX 100 which arrived yesterday with a handy 331 page manual. I am strictly amateur, and in my experience manuals and after market books do not often do a good job of explaining basics. I even have trouble with the pretty good Missing Manual series. So now I have confirmed the camera takes pictures, and am deciding do I go through the manual beginning with page 1 (already read some) or just jump around as questions arise. What I find inscrutable is the relation ship between the size (mb) of these pics and how much I can upload to my 2017 iMac. And haven't experimented with uploading to Adoramapix.com yet. Anyway, no panic, and I should make a "treat" out of working through this. Does anybody know where and how I can upload a 100 mpx frame if I ever take one (so far my "record" is 50+ and I'd like to know why). Thanks in advance to all responders.
