Digital Photography Techniques
Easy Digital Photography Techniques for Beginners
The photography tips given here will help the beginners to get the most out of their equipment and add to their knowledge of photography. Exposure, aperture, shutter speed, ISO, histogram, shooting modes, and the rule of thirds, etc., are some of the fundamental things to learn about photography.
Aperture, shutter speed, and ISO together make up Exposure. This is what the “Exposure Triangle” is all about. These elements have an effect on the exposure, motion blur, digital noise, and depth of field. You have to understand how each element works before you dive into the manual mode of the camera.
The aperture is actually the diameter of the hole inside the lens. Light enters the lens through an aperture. The smaller the aperture, the lesser light is allowed to get in and vice versa. It has an effect on the depth of field of the picture.
The f/number gets lower as the aperture widens and more light enters into the camera. It is desirable in low light conditions, but it makes the depth of field shallow. It is not ideal when capturing landscapes.
Exposure is much easier if you memorize the following f/stop scale:
f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22
Wider the aperture, shallow will be the depth of field and vice versa.
After passing through the aperture of the lens, light reaches the shutter. Now you will take the decision about how much of light you want to permit into the camera. Shutter speed is adjusted depending on the light available and the object you are shooting.
Normally, you need a small fraction of a second (1/250) to avoid motion blur. On the other hand, different shutter speeds set off different situations. For example, the sports photography requires really fast speed (1/4000) and the night photography needs slow speed (30 seconds).
The exposure can be increased by turning the ISO number up, but at the same time, there is more ‘grains’ or ‘digital noise’. It shows that the image quality is decreased. You have to choose between the higher exposure and the grains.
The histogram gives you a graph of the exposure. It tells you about the evenness of the exposure. LCD screen does not give you the best information through the display as it shows the brightness of the LCD itself and is affected by the outside lighting conditions you are in. Hence, it is one of the powerful tools to be used.
There are many shooting modes and it is all up to you to select which one you are going to use. They include; Creative-Auto, Shutter Speed Priority, Program, Manual Mode, Aperture Priority, and Sports Mode, etc. When you learn about all the modes, then you can select which mode is suitable under which condition. Of course, you must strive for mastering the Manual Mode but that would require experimentation with auto and semi-auto modes initially.
Rule of Thirds
The first compositional rule that all photographers come across is the rule of thirds. The composition works better if you split your camera’s screen into thirds and place key objects on these lines. It is a great way to improve your photos and make them effective whether you are a beginner or a pro.
