These days, you don't need to have to have an SLR with you everywhere in order to take a photograph. In our pockets, we have phones and the phone quality has improved so much that the cameras in your phone often rival those of a point and click camera. Three things to keep in mind though when you're using your phone as a camera. Firstly, composition is more important then ever.
Understand what the rule of thirds is. Look and learn about the world of composition. There is a grid that you can turn on on most camera's display on your phone. Secondly, invest in an app. The software that comes with the camera in your phone is going to be very basic, it's not going to give you a lot to work with. Spending between $2 and $5 in either the Play Store or the App Store is going to give you software that do a lot more with your photograph. Thirdly, remember that you cannot control exposure from you phone. You cannot control your shutter speed for those long waterfall shots or those beautiful night photos and you can't control your aperture to increase or decrease your depth of field.
As a rule, your camera is going to function on its ISO. That is, it's going to make the photo grainier in low light. So think about it when you're using it and secondly that shallow and not so shallow depth of field you have no control over. Fill your frame with subject because the background is going to be extremely noticeable. But remember the best camera you have is the one that you have with you right now. As long as you can take a photo, you'll never lose out on that opportunity for a fantastic shot. sss
