Reply to "POSTING PICTURES FROM YOUR COMPUTER"

DGOGR Forum Member

Just a quick update... I checked the size of the two Apple Compressed File (HEIF) pictures that I took for a different thread on OGR Forum that got me into this discussion, and their size was 1.2MB. Assuming that if I had used JPEG settings, I would have gotten a similar size to the above picture of 3.4MB, it sounds like Apple is using to 3 to 1 compression ratio which is not "that" bad. So my previous guess of 10 to 1 compression was not correct. Looking at the two Apple compressed files on a 24 inch monitor, I can see great details including counting rivets on a building.

As I posted earlier in the this thread, I converted the 2 pictures from HEIF type to PNG to post them on the other thread, and the size of the PNG files are 2.1MB, so again I don't think there was a whole lot of "loss" details.
