Mysterious change in picture files - Jpeg expert opinion needed
Hi all,
(short info)
Can someone tell me what caused the difference in the following two files ? It is the same picture, downloaded (copy/paste) from the same phone to the same win7 x64 machine at different times.
http://picpaste.com/DSC_0017-NkSWLXHf.JPG
http://picpaste.com/DSC_0017__2_-3viRfLKc.JPG
(details)
Usually I copy all the pictures from phone to a new folder, sometimes I delete them from phone, sometimes not. I discovered by chance that the same files that I copied at different times are different, it looks like some metadata change. I uploaded only a pair, but all files are affected the same way. I would like to know if the change was made by the phone itself (moving pictures to card storage?! software update?!), or some editor/viewer without user permission... however strange this might seem.
Phone is Sony Xperia Z2 (more details in file metadata), and the viewers I usually use for browsing are IrfanView, XnView and some old ACDSee...
So anyone who has an idea or can suggest a better place to ask the question, please help
Thanks

Re: Mysterious change in picture files - Jpeg expert opinion needed
Any idea why the maker notes are included vs missing from same files, downloaded at different points in time? Is there some setting on the phone?
Re: Mysterious change in picture files - Jpeg expert opinion needed
Perhaps your phone tried to detect faces later, and wrote the last 8 lines of exif metadata... and some other metadata were updated.. ?
Each software, each camera writes a lot of metadata using his own way ...
You can see some Sony metadata here : https://sno.phy.queensu.ca/~phil/exifto ... /Sony.html

According to Stuffware Photo Studio, there's also an empty EXIF GPS IFD in DSC_0017-NkSWLXHf.JPG which is missing in DSC_0017__2_-3viRfLKc.JPG.
