    Hi I am a new user of Image Master 2.0 software. I have same questions about calibration process:

    1.Is there a possibility to manually insert parameters of camera and lens to Image Master from different calibration software not from Image Calib ?

    2.In the documentation is written that for calibration the best solution is to select infinity focusing distance on lens. But when I am calibrating standard 35 mm focal length lens and A3 calibration sheet it is out of focus when I maximize it in image frame or very small in image frame and sharp. So If I have aerial photos with infinity focus Is that a good way to calibrate this lens with manual focus about 1m from the calibration sheet ? I can not print so big calibration form :(

    3.I have kite aerial photos taken with different apertures from f2.8 to f 8 and I want to use them as stereo pairs. What aperture I have to choose for making calibration prosess ? If I can not choose the same like in photos. Is that a correct way to choose bigger apertures with better deep of field like f22 or they must be more the same like in photos that I have, so something about f5.6 ?

    4.Where I have to manually select point of focus on calibration sheet ? Where must be this point ? In the center square pattern or to have better deep of field in 1/3 length from the nearest marks to the farthest ?

    best regards
