Depth of Field in photography can be defined as the distance between the subject and surrounding area that are in focus and the background that is out of focus. In another words, it is the range that appears to be sharp. Understanding the depth-of-field and using it wisely can make the difference between an ordinary photograph and a beautiful one.
When you are capturing a photo, you may want the subject to stand out from the rest of the surroundings. In some situations you want to remove the cluttered background. In such a situation you will have to go for an out of focus background or otherwise called as “Background blur”. There are many ways by which you can implement this.
Aperture, Shutter speed and International Organisation for Standardization (ISO) form the basic building blocks in photography. You should be able to control these 3 features in accordance with the environment and situation. Aperture setting is one of the most important factors to get a perfect shot and so understanding aperture is very essential.
There will be situations wherein you will have to use higher and lower values for aperture opening. So, you should know the effect or the change caused through different aperture values.
Rule of Thirds in photography is a well known, some would say infamous thumb rule used in photography. Imagine the photo divided into nine sections using two equally spaced horizontal lines and two equally spaced vertical lines. The four points at which the lines intersect are referred to as the points of interest. When you frame a picture, try to place the important elements in the frame in such a way that they coincide with one or more of these points. This will make the photograph more interesting and beautiful.
Taking the photograph of a moon can be little tricky. If you don’t expose it properly then you will end up in getting a bright circular white spot (white blob) in the image as moon. You may miss the details like crest and the shadows. I would always recommend getting a HDR (High Dynamic Range) image of the moon rather than going for a single shot. It involves taking 3 or more shots of the moon with varying exposure and combines them to get all the possible details.
If you want the photograph to look and feel good then there should not be any blur in your image. In order to make sure that you take blur free images, you should know the factors that causes image blur.
Image blur is caused due to many reasons. Firstly, the shutter speed selection. If you are shooting with your camera hand-held then if you go for a slow shutter speed. This can result in an image blur. Secondly, if you are capturing the image at a higher F-number, without using a tripod then you may end up in a blurred image.
