So far I've enjoyed the challenge of using my new Alpa system with my p65+ back. Experience is the best teacher, but to move myself along more quickly I hope to get some assistance from those more experienced with Alpa, and technical cameras in general.
I was intrigued by the Alpa and the stitching adaptor, and I hope to maximize some images using it. My question is regarding lens cast calibration. Am I correct in assuming that lens cast is lens/shift specific, and not really affected by other factors? If I were to create a calibration shots for each increment of shift for a lens, all at the same time, would that suffice? Or is it just easier to have the white plexi with you and just shoot them as you shoot?
Considering I am doing landscape work, and not architectural, I'm also wondering if I could create fewer calibrations, and just use something close to what I shot with in the field. So perhaps a 10mm shift would work fine with a 9mm calibration?
Which leads me to my last question (for now), do you normally log this info as you shoot, (lens, f-stop, shutter speed, shift) and if tips and tricks to make this efficient.
Any links to primers for technical cameras or blogs about real world experience using them would be very much appreciated.
