When the Subject Is Not in the Centre of the Frame It is hard to focus on a subject if it is not in the center of the frame, but you can bring the subject to the autofocus mark just enough to lock focus on it, and then, without lifting your finger off of the shutter release button, compose the frame as you like and take the picture. 1 While looking into the viewfinder, center the subject. 2 Press the shutter release button down halfway to lock focus. The green lamp inside the viewfinder lights up. 3 Compose the image as desired and press the shutter release button down all the way. When the Subject Is Too Close or Very Small If the subject is very thin or small, for example, when taking a close-up of E plants, it will be hard to focus on it. If that is the case, focus on an object at the same distance from the camera as your subject. 1 Set a substitute subject which the camera can lock on in front of the subject. 2 While looking into the viewfinder, press the shutter release button down halfway to lock focus. The green lamp inside the viewfinder lights up. 3 Hold the shutter release button down halfway, and remove the substitute subject. Then, recompose the picture, and press the shutter release button down all the way. For Better Images Nighttime Photography Auto Exposure Aperture fixed wideopen At normal exposure, nocturnal scenes come out too dark and unclear. This happens because camera exposure is set automatically and exposure takes place at standard brightness, even when the picture is taken at night. Nonetheless, you can take nighttime pictures at a more suitable exposure. Using the "M" mode, select a slower shutter speed. The higher the ISO rating, the faster the shutter speed usable to take pictures. However, these pictures will be grainy. Take several test shots and then select the best ISO rating. If it is difficult for autofocus to lock on the subject, focus on it manually (P. 31). Metering should be applied to a wide range, so center metering is the best choice. Also, with nighttime photography, shutter speed is set slower than usual, so even the slightest movement can easily affect focus. It is recommended to use a tripod. Again, a good idea with nighttime photography is to take several shots until finding a suitable aperture and shutter speed. E-63
