Hi everybody,
as someone of you already knows, some months ago I've bought a Cambo WDS technical camera which I use with my Hasselblad CFV-50c back and V lenses.
As soon as I've started using it, and also thanks to some interesting discussion in this forum, I've decided to develop an iPhone app which takes manual shots' annotations (lenses, iso, aperture, shutter speed, shift, tilt, ecc...) and is then able to export them into a data file.
I've also developed a companion desktop app which takes all those exported annotations and automatically matches and writes them into the EXIF/IPTC metadata of the images (RAW, TIFF or JPG) contained in specified folder. I'm almost finished with the first version of this solution. It works pretty well and flawlessly.
The desktop app gives the following options:
I've already found where the shift metadata are written, but right know I'm not sure on how to interpret the values. It seems that there is the rotation of the camera (or is it the back which rotates?) to take into account.
To discover this I would need RAW files coming from a P1 XT camera, the only one to my knowledge which is currently able to automatically write shift informations into the RAW file. So I'm here to ask if someone of you who owns a P1 XT would be so kind to take some test shots for me with right/left/up/down shifts on both landscape and portrait positions and send the produced RAW files to me.
I hope I'm not hurting anyone's sensibility nor infringing any P1 business/copyright/patents by trying to extend the P1 shift annotations to people using P1 backs with non P1 technical cameras.
If you think I'm doing so, please let me know and I will skip this feature implementation.
Thank you in advance.
Kind regards,
marco

- write all the annotations into the IPTC "Instructions" field as a descriptive text.
- optionally write the annotations to the corresponding EXIF metadata (Iso, exposure_time, ecc...).
