I was doing some experiment with photo , tonight i took to black photo that are very smal 8k , 8143 byte and compared them , apart the exif data/time i discovered that they differ slightly because the black its a repeated pattern
A0028 A0028 A0028 A0028 0028A 0028A 0028A 0028A 028A0 028A0 028A0 028A0 28A00 28A00 28A00 28A00 8A002 8A002 8A002 8A002
This is the real difference just few bytes
