xConvert vs. PM

[Andymann]

Attached image test_1.jpg was converted with xConvert down to 72 dpi. But why is it shown in PM (latest build) as 305 dpi? Same in PS CS 2. XConvert says "everything is fine".

It's because xConvert didn't update all resolution metadata tags:

Code: [Select]

exiftool -'*resolution*' test_1.jpg
[JFIF]          Resolution Unit                 : inches
[JFIF]          X Resolution                    : 72
[JFIF]          Y Resolution                    : 72
[EXIF:IFD0]     X Resolution                    : 72
[EXIF:IFD0]     Y Resolution                    : 72
[EXIF:IFD0]     Resolution Unit                 : inches
[EXIF:IFD1]     X Resolution                    : 72
[EXIF:IFD1]     Y Resolution                    : 72
[EXIF:IFD1]     Resolution Unit                 : inches
[Photoshop]     X Resolution                    : 305
[Photoshop]     Y Resolution                    : 305
[XMP:XMP-tiff]  X Resolution                    : 305
[XMP:XMP-tiff]  Y Resolution                    : 305
[XMP:XMP-tiff]  Resolution Unit                 : inches
When conflicts in metadata exist, software has to choose one over the other and here PM chose the one in XMP over the one in EXIF

Thank you. And what does this means for me? Just disregard and forget it?

Thank you. And what does this means for me? Just disregard and forget it?

If you're in contact with the xConverter developers, ask them to update all of the resolution tags and not just some of them.
