A card adapter includes a first memory card interface configured to be connected to a first memory card. The cam plate is set such that a rotation center coincides with a center of gravity. Also, a photographic material, comprising a transparent support having thereon at least three kinds of light-sensitive hydrophilic colloid layers each containing any of yellow, magenta and cyan dye-forming couplers and containing silver halide grains different from each other in color sensitivity, and at least one light-insensitive hydrophilic colloid layer. In one embodiment of the invention, a smart software can be employed to provide visual plots of \u201cgrowth curves\u201d, including real-time calculated datapoints and their confidence intervals, and automatically terminate the recording session upon reaching a pre-set trigger.
