The iPhone camera is reasonably high quality, but taking pictures with it can be tricky. Learn how to take the best pictures possible with your iPhone.
When I first got the iPhone, I was very impressed by its 2 megapixel digital camera. My previous phone had had a really awful one and the pictures it took were little more then blurs. The iPhone camera, on the other hand can take fairly good pictures of close-up things and, in good light, even area shots turn out well.
Unlike almost all other camera phones, the iPhone's camera actually snaps your image when you release the Capture button, not when you first press it. This allows you to hold down the button until just the right moment that you want to snap your picture. This may seem counter-intuitive at first, but once you get the hang of it you will find this feature helps take better pictures
One of the trickier things about the iPhone camera is how hard it is to get a still picture while just holding it in the hand. I don't know why it is, but the camera seems to update what it sees very rapidly, which makes it blur more easily. There are a few simple tricks you can use to reduce the number of bad takes.
First, make sure the image you want to take does not have any bright light sources in the middle of it (lamps, the sun, etc.). The camera adjusts pretty well to the light of the room, but a single point of light can throw off the adjustments.
Next, find a way to hold the camera steady. The easiest way to do this is to sit down and pull your knees up onto your chair. Placing the iPhone between your knees and holding it by the top will make it easier to steady. Also, this will help reduce blur when you press the capture button. If you can't sit down, you can try leaning on the shoulders of another person sitting down. This is called a "human tripod."
If you happen to have an iPhone stylus, it can be useful for depressing the capture button. While most actions are easiest with a finger, the stylus is good for hitting the key exactly when you want to.
The nature of the iPhone is such that it limits what a user can do to enhance their own experience. Apple has tried to do all of the tweaking for you, so there isn't too much more you need to worry about. Good luck taking pictures. If you have any tips not mentioned here, leave a comment!
