Great photography is in demand across many fields. Photographs are used in newspapers and magazines, advertisements, posters, television, the internet, passports, ID cards, and more. They are also important in domestic activities, such as family gatherings and celebrations. Whether taken using a digital camera or with a traditional camera, photographs can be used for both commercial and personal use. Increasingly, people use photographs to share experiences and memories with others, and can even be displayed on photo-sharing websites.
Exposure refers to the lightness of an image. An under or over-exposed photo is a poor-quality photograph. The concept of exposure is derived from the way a camera works: it exposes a digital sensor to light. Three basic settings determine exposure: manual, automatic, and manual. Manual exposure is the most versatile of the three, allowing you to adjust each setting independently of one another. Photography is about creating images that capture the world around us.
The camera allows the photographer to change the subject's characteristics and add their own unique interpretation. Taking a picture is a complicated process, which involves a lot of skill. A well-trained photographer can control the vantage point and the exact moment of exposure. Photography is a unique medium that allows the human mind to record the visible world, disseminate information, and increase the knowledge of humanity. Photography has been dubbed as one of the greatest inventions since the printing press.
Whether you want to make a career out of photography or use your passion for the art, there is a right way to start. The first step in photography is to experiment with a compact camera or a phone camera. Try taking photographs of anything that catches your interest. The Auto mode on most cameras will automatically adjust the camera settings. It won't matter what you use for exposure, because the camera will do all the work for you.
Composition is another vital part of photography. Changing the composition of an image requires changing the viewfinder and the angle of the camera. To change the composition, you can kneel down, use a ladder, or stand up. You can also learn the elements of composition, such as the rule of thirds, which helps determine where to position the subject of your photograph. The next few chapters will cover shutter speed, aperture, ISO, and composition. Once you're comfortable with all of these, you can start practicing your photographic skills.
The first negative was made by William Fox Talbot in Lacock Abbey, England. William Fox Talbot's negative image may be the oldest known photographic negative made by a camera. Later, Hercules Florence and Joseph Henry Mercator worked to create a silver-salt-based paper process. This technique became known as "photography" and was renamed after him. Its success made it the most popular photographic medium.
