The Sekonic Exposure Profile Target II provides the photographer with an easy, reliable and fast way to test your camera's sensor. Sensors, being as touchy as they are, can be subject to a variety of influences when shooting. This target gives you the chance to find out exactly where your sensor falls on the exposure scale.
By making three basic exposures (one centered, one at +3 and one at -3), you can easily find the right exposure for any camera lens combination.
Note:
Compatible with Data Transfer Software as well as the 758DR and 758C meters
