mage aquisition tips:

any camera can do BUT higher resolution = higher model detail
always shoot raw - process if necessary - export tiff / jpeg
use fixed focal length / 24mm - 50mm recommended
if variable zoom then keep it always at minimum or maximum length and don’t change it while shooting
constant aperture f/5.6-8.0 (f/11 max)
keep whole object in focus
iso as low as possible 100-800
diffuse light - no hard shadows!
camera orientation depending on subject - fill the frame
increments of 10-15 degrees between pics
overlap two thirds / 60% of last pic
no over- or underexposed pics
use gray card / color checker if necessary
use printed measurement markers / tennis balls for big scenes / or when footage origin differs
use tripod when low light or turntable
shoot from as many angles as possible, up to down and around
always take more pics than necessary
