Title: Panasonic Tags 0x002F - 0x0032
Post by: Klaus_Homeister on June 07, 2018, 12:11:56 PM
Hi Phil,

I can not find those basic Tags in Exiftool.

When you set up my GX-8 to shooting RAW&Jpeg
and Image-Format for example to 3:2 instead of native 4:3 ..
then those Tags get the coordinates of the selected ImageFormat within the full Sensor size

Dump of my Softwares output:
@1B2    [No.34] Tag 0x002F      SHORT × 1  JpgCropTop  492
@1BE    [No.35] Tag 0x0030      SHORT × 1  JpgCropLeft  8
@1CA    [No.36] Tag 0x0031      SHORT × 1  JpgCropBottom  3412
@1D6    [No.37] Tag 0x0032      SHORT × 1  JpgCropRight  5192

by the way:
It's interesting for me because it shows that Panasonic doesn't use the better quality center part of the Image where distortion-correction is much lower than in extreme corners.
This way I'm not satisfied with those disharmonic Jpegs.
Someone who likes 3:2 should always keep 4:3 shooting and manually crop _centered_ to 3:2 later.

Greetings from Germany

Hi Klaus,

These tags are found, and decoded by ExifTool, from IFD0 of Panasonic RW2 images.  They aren't found in JPEG images.
