When scanning film with a digital camera there are only two absolute musts in regards of captured image: it  should be uniformly sharp and focused from the edge to the edge.  Those two qualities can only be achieved when:  the film holder is absolutely parallel to the camera's sensor plane (and keeps film absolutely flat) and you need a lens which is capable of faithfully reproducing your image at 1:1   scale ( or around that value depending on the camera sensor size and film format)    The first requirements can be achieved by carefully positioning and fine-tuning the camera so that when the image to be captured is in focus, it neatly fills the camera frame, and the center and all the corners are equally sharp. The "Vlads Test Target" (Google it!)   has been designed specifically to allow visual control and the best alignment detection. The Vlads Test Target film strips are so sharp that even the slightest loss of focus causes image edges in the digital camera to b

In this innovative offering, the ten USAF 1951 test patterns are strategically placed throughout the 24x36mm film frame - one in the center, and the others scattered across sides and corners. This unique arrangement facilitates a comprehensive evaluation of the sharpness and focus across an entire negative or transparency/slide in one shot.  P hotographers can now accurately evaluate the performance of their lenses and camera systems across the whole frame. This is particularly advantageous for detecting any discrepancies or weaknesses in image quality, which might typically go unnoticed with conventional  single-pattern USAF 1951 target needing to be moved in camera field of view. Clean, nice, sharp corners make or break the great scanned image    Welcome to www.film4ever.digital - the home of  USAF 1951 Resolution Chart on real 35 mm and 120 film aka Vlads Test Target !
