Event or portrait photography, casual or professional, ultimately, photography will be a balance between art and science. Without the technical knowledge, the photographer will have little or no control over the type of photos they eventually get. One will end up surprised at what the camera did and why. Without the technical knowledge, the likelihood of photos appearing blurry, too dark or bright is very high. Photography must not rely on luck. Technical knowledge gives the photographer as much control as possible.
Just as important for the event photographer is the artistic eye. Without it, they will only make mechanical photos which are flat and uninspiring. The artistic side involves figuring out the feeling being passed across and learning composition rules. A delicate balance of these two sides of photography makes for the best professional. In professional circles, understanding that balance results in an understanding of the difference between taking and making photos. The person who takes the photo shoots and hopes for a lucky shot. The one who makes photos is the one with the most control over all the photography features. Here are some points to review on choosing the right photographer, visit this page.
With that in mind, the next thing a budding photographer should take into consideration is exposure. Exposure is used to refer to the amount of light that hits the camera sensor. Overexposure refers to too much light hitting the sensor, and the picture being too bright. If there is too little exposure, then the picture will be underexposed and dark.
Without a good understanding or control of the exposure situation, then one is better off just trusting their camera to make the judgment. Cameras make good guesses, especially when set to automatic mode. There are three variable when controlling exposure that must be dealt with.
The first variable is the ISO, which is the measure of the sensitivity of the camera sensor. The ISO feature was derived from the old days when ISO 200 cameras were the most appropriate for the outdoor event photography and ISO400 for the indoors. The danger for ISO adjustments is that the picture will tend to get grainier.
The second feature when it comes to exposure is the camera aperture. This is the size of the hole of the lens. A bigger lens lets more light in, and results in overexposure. The aperture size is measured in units called F stops, sometimes also called stops of light. As the F stop number gets smaller, the aperture gets bigger. Aperture is important because of the depth of field. The depth of field is how much in focus the picture is. A high depth of field is when everything is in sharp focus. If some of the features are in sharp focus and the rest blurry, the depth of field is referred to as narrow.
The third aspect is the shutter speed, which is the speed of opening and closing the aperture hole to let in the light. With ISO constant, aperture and speed will trade off. If the aperture is huge, then the speed needs to be really fast.
