ISO, shutter speed, and aperture. The lower the ISO number, the less grain, and the better the image quality. Shutter speed controls the movement recorded on the sensor. Lower shutter speeds allow for more light to hit the sensor, causing movement in your image. Aperture controls the depth of field in your image. The lower the number, the less depth of field, and vice versa.
White balance helps keep your subject looking true to life. Adjust your white balance to match the lighting around your subject, depending on if you are shooting in bright daylight, in an overcast or otherwise darker environment, or in a studio with artificial lighting.
If you’re outdoors, make sure you adjust before snapping. Shadows from the sun are harsh on faces, so try to find a shaded area, or pose your subject with the sun behind them. The best time to shoot outdoors—what photographers call the "golden hour"—is right after sunrise or before sunset, when the sun produces soft, even light.
Indoor photography almost always requires some flash, but consider using a flash in outdoor photography. If the background is too bright, your subject will look dark or silhouetted. Using "fill flash," like the Hasselblad True Zoom’s xenon flash, will balance out the background light and brighten your subject.
The Moto Z™ Droid with the Hasselblad True Zoom Moto Mod™ has a 10x optical zoom, not digital. That means no loss of resolution when you zoom all the way in. However, be aware that zooming leads to camera shake, so use a tripod or keep your elbows tight by your side and hold steady.
