Drifting slightly off the topic, but OP stays quiet.
Mark,
I think I misunderstood you upon first reading.
At first I thought you meant that cropping and exporting to jpeg
produces better results than cropping the exported jpeg image,
but it seems the two operations do commute.
Now I assume you meant that comparing DP and DPXD full pictures on a monitor
(even 4k) will reveal the differences only on cropped images.
In other words, the differences between uncropped images would be seen
only on large prints, or on the monitor when enlarged to 100%.
It has nothing to do with AI/ML inventing and NOT inventing.
Actually, the first time I used DP(XD), the following differences popped,
when viewing full size pictures (at about 50%, so below the 75% threshold
for some corrections to be displayed, 24MP camera, 27"/4k):
- background and shade noise (less for DPXD at high ISO)
- microcontrast, acquity perception, details (more for DPXD at high ISO)
- color (minor, yet to be investigated, perhaps microcontrast related)
- jpeg size (often 20% smaller for DXPD, even at low ISO)
- exporting time (1.5-3 times slower for DPXD than DP)
Barely noticeable differences in images at moderately high ISO, even at 100%.
Agrees ± with DeepPrime XD - is there a type of image it is most useful for?
Flat wall decorations (everything in focus) would almost always look better
with DPXD than DP, I presume.
