With a push of the Elura 100's convenient omni-selector joystick, you can lock your exposure settings, then recompose your shot. For example, you can lock your exposure while zoomed in on your subject. Then, even if you zoom out and include a very bright or dark background, your Elura 100 will still be giving your subject the right exposure. Also, by shifting the omni-selector left or right, you can adjust your exposure by up to +/-11 stops (+/-2.75 EV).
Three different metering modes give you the right exposure under different lighting conditions. Evaluative metering sets the exposure based on the entire frame. Center-weighted average sets the exposure according to the lighting in the center portion of the frame. And Spot sets the exposure according to the lighting within a specific area in the frame -- perfect for subjects in front of a very dark or light background.
