The aperture is the part of the camera that controls how much light that will reach the sensor. It looks like the image on the left, those blades can make the hole larger or smaller depending on the settings.
What makes a great picture of people? Ninety percent of its quality lies in the facial expression, the rest is composition, lighting, and the natural presentation of body language. A tripod is a plus for sharp pictures and the camera should be set at the lowest ISO speed.
It's true that taking photos is as simple as running out and grabbing a cheap five dollar camera. But taking good, quality photos has never been easier. So lets explore some quick ideas that can help you take photos that you will be happy to share with friends and family.
The Shutter controls the time the sensor will be exposed with light. The longer the shutter is open, the longer time the sensor will be exposed. So what this means is that the aperture controls how much light the sensor can be exposed to and the shutter controls for how long the sensor will be exposed. The aperture and the shutter are together the most powerful tool to create your photograph the way you want it.
Photography at night can be used to create amazing pictures. For this kind of photography a tripod is almost a must. If you want to get a clear exposure with a great depth-of-field, then you will need a tripod. Usually when we take pictures of sunsets or bright lights we just center all the coloring and shoot the picture.
Do you know what ISO is? Perhaps not. And, in fact, you don’t need to know what it is – just how to use it. In very simple terms, the ISO setting is a measure of how sensitive your camera sensor is to light. A low ISO (e.g. 100) will not be very sensitive to light whereas a high setting (e.g. 1600) will be very sensitive.
Photography remains just that when you convert to digital cameras: you still have to know how to compose and shoot pictures to get the best results. The way you see your subject, and visualize the resulting image doesn't change in any basic way.
