Because, I'm trying to calibrate the lens on my ipod touch 4g, and that requires knowing the focal length and crop factor (or 35mm equivalent focal length). The EXIF data says it's 3.85mm focal length, but there's nothing about crop factor or FOV or sensor size, and I've scoured the web via Google. I did find this: http://www.extinguishedscholar.com/wpglob/?p=806, but I don't trust those calculations, especially when the focal length has been rounded to 3.9mm from the start. On one of the 360 degree panoramas I made, Hugin calculated the HFOV at 44.09334 degrees for every image (all taken with my itouch). Can I trust this figure and use it to calculate crop factor and 35mm equivalent focal length?
And, please, before anyone says it's not worth it, know that that's a huge part of the fun for me - figuring out how to squeeze the best quality out of very limited hardware through shooting technique and software. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
