Original picture / library size ratio 1:3 ???
Hello all,
my Photos library consists of 21.000 photos that come in varying sizes depending on cameras and file formats. The size of the whole library is 160 GB. As I found this to be a bit large, today I checked the size of the "Originals" folder that is to be found in the library package. To my surprise this one is only 60 GB! Going through other folders I found out that the previews of most pictures take 3 MB each, previews of files that only have around 5 or 6 MB as their originals!
So I guess my question is: Is this normal that the photos app blows a library to almost three times the size of the original photos? I know that the app always keeps the original when I tweak with a picture, but I'd estimate that I have only post-processed around 25 % of my photos.
So what do you say: Normal or not?
