Hi all,
I am a Masters of Building Science student in New Zealand and for my thesis, I am using HDR imaging as a tool for daylight analysis by employing the use of an Android Smartphone with a fisheye lens.
Unfortunately, the photos taken from my Motorola Defy does not include the "Exposure Compensation" or the "Exposure Value" in the EXIF file which I need so that I can fuse the four photographs together into one HDR image.
I have downloaded exiftool.exe and have sucessfully installed this. However, I am stuck as to how I should go about adding this value in. I have tried opening the EXIF information as a text file, but am unable to save the information...
And when I tried to view the exposure compensation information through command promt, this warning pops up:
Warning: Invaild size (4294967295) for IDF0 tag 0x8827 - imagefile.jpg
Any advice is much appreciated!
Kind regards,
Peony
Hi Peony,
It sounds like the metadata in this image is corrupted. If you send me a sample image (philharvey66 at gmail.com) I will take a look.

I got the image, thanks.
Yes. Whatever wrote this image doesn't know how to write EXIF. Your best bet is to rebuild the EXIF with ExifTool. See FAQ number 20 (https://exiftool.org/faq.html#Q20) for details.

Thanks Phil, will try and do that =)
