...This is not original PCD , it was maked by JPEG [lossy] converted to PCD [lossles], quality is from JPEG [nonprintable/wallpaper(aka :no DPI/PPI), not for photo!!!
Is a stupid ideea to convert lossy file to lossles ...it increase no. of MB.of the file but not changing in any way the quality of the file, that is execrable[stupid]!!!
the PCD Photo have exif and DPI from 300+, that on your file is missing...and JPEG quality is low between 75-80...
