BASICS OF PHOTOGRAPHY - 2

- Continuing the points from last story

4. ISO - The last of the exposure photography basics is the ISO.

In short, the ISO works by increasing the light information captured by the camera sensor.

This has a drastic effect on the exposure; the higher the ISO, the brighter the image will be, and the lower the ISO, the darker the photograph will be.

5.DEPTH OF FIELD - One of the fundamentals of digital photography is the depth of field.In short, depth of field is simply the space in the image that is acceptably sharp and in focus.

In photography, we can say that there’s a shallow depth of field when just a narrow portion of the frame is acceptably sharp, whereas we speak about a large depth of field when a big portion of the frame is considered to be in focus.

6. FOCAL LENGTH - Focal length is related to the photography lens basics.The focal length works by describing each lens in terms of millimeters from the optical center of the lens to the sensor. Depending on how short or long the focal length is, this will have a direct impact on the field of view of your images and in other aspects like the depth of field.

For example, shorter focal lengths like wide-angle lenses will have a wide-angle of view, whereas longer focal lengths like telephotos will have a narrower angle of view.

7. FOCUS - Focusing is one of the most common struggles for anyone beginning in photography.

Briefly, focusing consists of adjusting the lens to find the maximum sharpness, contrast, and resolution for a chosen subject.

There are two ways to focus in digital photography:

Manual focus: Using your hands to tweak the focus ring until you get to the best focus.

Automatic focus: Using the camera’s and lenses’ internal motors to focus on a given subject.
