Kodak Q-14 Step chart and GretagMacbeth ColorChecker ®<br />

These charts (normally framed much closer) are analyzed with <strong>Imatest</strong> Stepchart, Colorcheck, and Multicharts. They are<br />

mounted on neutral middle gray (~18% reflectance) mat board, which is mounted on foam board for rigidity. Shown in front of the<br />

wider slanted-edge target. The Q-13/Q-14 can be mounted vertically to reduce glare when used with wide angle lenses.<br />

OECF target, available from Applied Image<br />

The OECF target is valuable for measuring tonal response in cameras that have significant light falloff (vignetting)— especially<br />

for cameraphones, which are constrained to be extremely thin.<br />
