Yeah, I used to upload things in a smaller format. Anymore, I'm not overly concerned. What's 4Mp of 80+? Insignificant. How large would you like?
Collaterally, I've printed this full-size at 44'' by 60'', or something close to that. Amazing. Even up close, the detail astounds. While I'm sure the next generation of MFD backs will be higher resolution, I am really just not all that concerned. 80Mp feels perfect.
