I used to process color negatives and print them up to 16X20 in my basement back in the late 80's and early 90's. Maybe that is the cause of my head twitch , I am glad to no longer work with those chemicals.amazing... I thought it was about that size. It's evidently very pixel dense for the resolution you indicated above post. Much smaller pixels than a FF.
These new technologies continues to amaze me. At times I'm still in awe in the size of digital image files and the level of manipulation that can be performed. Remember when digital first hit consumer level availability.... everyone compared it to film and how inaccurate, low performance, slow to process, the digital was in comparison to capture the light and the blinking of the cache light writing a single image to memory, and now just a short 20 yrs later it's awesome.
