An iPhone is a capable device for a daily snapshot. It is not as versatile as a dedicated digital camera but you can still take stunning portraits. There are great techniques for top-notch people shots using the camera that you always have with you, your phone.
Reflectors for Fill Light
The iPhone has LED flash and is decent for indoor photography. But it's not strong enough if you need a fill flash in bright daylight conditions. If you're outdoors you can add extra light to your pictures by using a reflector.
Photographers usually use collapsible disc reflectors. Chances are that you don't have the successor in your backpack but you might have a car windshield shade available.
If you're doing a self-portrait, hold the reflector on the opposite side of the sun and bounce the light on your face. Any friend can help you do this and hold it instead. Windshield shades have both a shiny and white side. In a bright condition, the white surface should work. On a partly cloudy day you might want to use a shiny side to give you more light on your subject. Read 16 iPhone Photography Applications & Accessories to Improve Your Photos.
Put the camera on a stand
You will have many posing options if you have a camera on a stand. There are many portable options available including the Lollipod.
I stand helps reduce distortion by positioning the camera parallel to the plane of the subject. You may want the drama of a high or low camera angle and other times not. The key is to control your composition. The stand gives you that option.
You can use the front facing Face Time camera to help you compose your self-portraits. It allows you to see the framing on your LCD. You can take some test shots and judge lighting and color. Once you have everything aligned you can turn the iPhone around and use a higher resolution back camera for the final image.
You can also trip the shutter using a set of earbuds that come with your iPhone. You just plug them into the headphone jack, and when you're ready to shoot you compress the volume plus button on the earbuds and it will take the picture for you. Your earbuds are a remote release. It is an alternative to use a self-timer option that comes with the many camera apps, such as ProCamera.
Many times we see them on social networks with self-portraits that are shot with a mirror. The advantage of this technique is that is fast and easy to do.
