Perhaps the easiest (to understand) solution, at least for the landscape vs portrait mode problem, is to take max(HFOV, VFOV), in other words, the FOV of the greatest dimension. This is pretty easy to guess from a user perspective in case of missing EXIF information. I've thought about a DFOV as well, but I don't really think this is the best way to circumvent issues like these.
Focal length is nice of course, but what it does exactly is dependent on the sensor or film size (hence the existence of the all but beautiful "focal length 35mm equivalent"), which in practice can make it less obvious, and also it's less easy to guess, especially when one does not have a photographer's background. In the end I think there are good and bad things with any chosen unit. Working internally with a focal length in pixels (or a pixels per angle ratio) and presenting a FOV to the outside world might be a nice mean. -- Bart --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
