1. Contact points
The most important thing to keep in mind when holding your camera is maintaining good contact points. Contact points support your arms, and help you hold your camera steady. While standing, you can usually achieve this by resting your elbows against your body. Make sure you maintain steady contact points in other positions as well. For example, while kneeling, a lot of photographers will rest their elbow on their knee. However, this isn’t a good contact point as the joint-to-joint contact causes a lot of jostling about. Try shifting your elbow back so it rests on the meat of the leg instead. As a rule, softer surfaces will cause less jostling, and you will end up with clearer pictures!
2. Landscape orientation
When holding your camera in landscape orientation, make sure that your elbows are tucked in tighty against your body. Though this may feel awkward, it will make a difference to the quality of your photos in the long run. Next, be sure to press the viewfinder firmly against your face. Turning your head slightly so your camera rests against your cheek provides an additional contact point and extra stability.
3. Portrait orientation
This is one of the most difficult orientations to hold your camera in. The vertical position requires elbow to be raised in the air, and therefore, you are losing a contact point with the body. However, there are a few things you can do to increase stability while taking a portrait. Lean back slightly and make sure your elbow pointing down rests against your chest, so you at least have that contact point. Rest the camera against your cheek for extra stability. Finally, if you don’t have a battery grip, consider purchasing one as this will prevent you from having to reach up and over your camera in the first place!
