DEPTH OF FIELD IN PHOTOGRAPHY

DEPTH OF FIELD IN PHOTOGRAPHY

If you want to grow your photography to an advanced level then you must understand Depth of Field.

Depth of field defines that how much area is blurred before and after the subject in your image, Through Depth of field you can compose the image and show your subject properly into the viewer’s eye.

There are two types of Depth of field.

a) Shallow depth of field.

In Shallow depth of field, only the main subject will be in focus, and the area before the subject and after the subject will be a blur. as shown below:

b) Deep depth of field

In deep Depth of field, a larger amount of image is in the focus, the line between the nearest and farthest elements that are reasonably sharp is long. as shown below:

WHEN TO USE DEEP AND THE SHALLOW DEPTH OF FIELD WHILE TAKING THE PICTURES?

You have to use deep depth of field when photographing landscapes (daytime and at night), seascapes, cityscapes, and architecture.it keeps more of the image sharp and clear. Whereas while shooting portraits you need shallow depth of field to blur the background and show the main subject in focus.

Depth of field has a direct relation with the lens aperture. like if you set your aperture numerically low. For example- f/1.8 f/2.8 f/3.5 you will get shallow depth of field whereas if you set the aperture numerically high. For example- f/8 f/11 f/16 f/22 you will get a deep Depth of field.

ACTIVE D-LIGHTING IN PHOTOGRAPHY

WHAT IS ACTIVE D-LIGHTING? Active-D Lighting expands the dynamic range of your camera’s sensor Active D-Lighting is often best left off when shooting in RAW. There is a glossary. When strong lighting increases the contrast between bright and dark areas of an image. It causes the shadow and highlight details to be lost as shown in the image below. The image on the left shows the balanced lighting achieved when Advanced D-Lighting is turned off. The image on the right was taken with D-Lighting turned on. Notice the dark areas in the foreground and background of the image. WHEN TO USE ACTIVE D-LIGHTING ? Basically, it is used in low light conditions or extreme sunlight conditions to expose the image well without changing the other parameter to get the perfect details in the image.

COMPOSITION IN PHOTOGRAPHY

COMPOSITION IN PHOTOGRAPHY Composition in photography refers to the position of elements inside the frame and how they interact with each other. Ultimately, the composition is about the visual structure of your image. By using composition your photo looks very attractive and interesting and it will be easy for the viewers to understand the subject and the story of the image. Note : Y ou cannot click good images By just using ISO , Shutter Speed , and Aperture . You need to understand composition as well to take appealing images. THE ELEMENTS OF COMPOSITION a) THE RULE OF THIRDS Using the rule of thirds in photography creates visual interest and impact in your photos. Gridlines divide your scene into thirds, both horizontally and Vertically. These lines and the four points at which they meet create areas on your frame for placing subjects and essential elements as shown in the image below. b) CENTERED COMPOSITION If your frame is wide and if you found foregr...

EXPOSURE TRIANGLE IN PHOTOGRAPHY

EXPOSURE TRIANGLE IN PHOTOGRAPHY It's all about the camera's manual mode of operation. To get a perfectly exposed image you need to understand the exposure triangle well. This is an exposure triangle that has three important terms which are related to photography that is: a) ISO b)SHUTTER SPEED c)APERTURE This exposure triangle diagram is a great reference to use when determining what settings will allow more light in and what side effects it would entail. WHAT ARE CAMERA MODES? HOW DOES IT BE WORKS? The camera can be used in three modes. a) Auto Mode - In auto mode you don't have any control over the camera. It will automatically set all the parameters like iso, shutter speed, and aperture as per the scenario by itself . b) Aperture-priority Mode (A)- In A mode you have to set your aperture as needed and the camera will automatically set the other parameter Iso and Shutter speed on its own. c)Shutter-priority Mode (S)- In S mode you have to s...
