A creative angle has the ability to instill dramatic and emotional response. Like when a dog tilts his head when he is curious, this tilt makes us smile and laugh. It invokes a response, and this is what makes a photo interesting. First and perhaps most importantly is to keep your camera steady. This may seem obvious but you would be surprised to know how little movement it takes to blur and ruin an otherwise perfect shot.
Most new cameras have auto focus.
This in combination with the shutter speed being preset at a higher speed allows for most point and shoot cameras to take very sharp images even when there is alot of movement. This is why these type cameras are called point and shoots because all you have to do is point it at what you want to take a photo of and press the shutter button. It's all automatic. Also called the zone of focus or depth of field zone. The size of the aperture is adjusted by setting your f-stop.
