All, I have been creating HDR images for purposes of pixel-based luminance analysis from photographs captured with a PointGrey Firefly MV [FMVU-13S2C (Color)].
http://www.ptgrey.com/products/fireflymv/fireflymv_usb_firewire_cmos_camera. asp It is a board level camera with usb 2 connection, uses the Sony IMX035LQR-C cmos sensor and a rolling shutter. I have fixed exposure to 1, brightness to 0, gain to 0, and turned the frame rate off. I have then run multiple exposures (10-12) using shutter speeds from 1ms to 8000ms excluding completely saturated exposures. I have a fisheye lens attached but have not been able to run vignetting correction yet since I do not trust my response curve. I have been running accuracy comparisons to my Canon which I trust with poor comparisons. It is successfully resolving in Photosphere, but only after I manually write the EXIF header since the camera actually does not write an EXIF header. I have written camera make, model, f stop, and shutter into header. Any ideas? I would be happy to ftp exposures etc if it would help. Thanks for any help!
