I'm using a Canon PowerShot G12 camera to take photos for vegetation analysis. The camera is looking straight down at the vegetation - or at least CLOSE to straight down. The autorotation function on this model of PowerShot cannot be turned off. Because the camera on the pole we carry through the field may be slightly tipped in any direction, the images are autorotated in all directions. We're saving RAW images.
Is there a program that can read the EXIF and orient all the images so bottom of the camera is the bottom of the image?
I can take up to hundreds of photos on a day, so I don't want to rotate image by image in Digital Photo Professional. And the powers-that-be are hesitant to use a CHDK.
