Using the EOS-1N's 16-zone Evaluative metering system The EOS-1N's Evaluative metering system gives you high metering precision, providing optimum exposure for a wide variety of shooting conditions, including backlit scenes or extremely bright or dark subjects. The key is a microprocessor-controlled metering system that evaluates lighting conditions in 16 different zones. And thanks to Canon's advanced AIM system, subject position is also evaluated using the active focusing point as the most heavily weighted area, so exposure is based on the reading from the primary subject. The 16-zone system is a world apart from the 6-zone version used in the original EOS-1 camera. First used in the EOS 5 camera, it was refined and improved further for use in the EOS-1N and its high-speed variation, the EOS-1N RS. From the sunrise images shown from Photos A to D, where all were shot using the EOS-1N's Evaluative metering system. Correct exposures were obtained by placing the optimum AF point (out of five available) on the right subject. For Photo A, shot at 28mm, two of the camera's AF points were locked onto the incomplete Telekom Tower on the left. The EOS-1N was slanted at a 45i angle to enable the metering to place emphasis on the Tower while taking into consideration the brighter sky and darker mass in the foreground. The resulting image did render the atmosphere exactly as I saw it before recording the scene on film. For Photo B, a 300mm lens was used to get a closer view of the tower and the orange-coloured sky in the background. Again, the EOS-1N was slanted to enable its Evaluative metering take into consideration the brighter sky while computing the desired settings for correct exposures for both subject and background.
For Photo C, the building on the left is no longer the Telekom Tower but the same method on Photo B was used to record the same rendition on film. In Photo D, as the sunrise gained momentum, three AF points were used to take readings between the shadowed land mass and the orange-coloured sky. The brighter part of the sunrise was ignored in order not to fool the EOS-1N into setting the wrong exposure values. The resulting image speak for itself.
Like the EOS 300 and EOS-3 models, the EOS-1N's 16-zone Evaluative metering system placed special emphasis on the main subject and ignored other elements that might fool the camera into giving the incorrect exposure settings using any of its 5-point AF sensors. Look at Photo E, the decorative item (200mm) used by KL's City Hall around the capital was rendered correctly despite the brighter background. Two AF points on the left side of the EOS-1N had locked onto it and ignored the rest of the background. In Photo F, moving back and shooting the same area on a wider view (100mm), the overall scene was correctly exposed as well despite having the white-coloured KTM Railway Station building occupying most of the frame. The exposure is perfect because I have the AF points locked into the buses and cars located below the frame and let the metering took care of the situation.
