We can all admit that cameras are pretty challenging contraptions to take photos. Especially DSLR cameras, we can’t initially figure out the buttons, the guides, and even the indicators presented on screen and how it will tell us that the scene we are trying to capture is a good take.
With that, here are some aspects you need to look upon in order to guide you in taking a beautiful photo with your professional camera (or with any camera.)
How do cameras work?
It is summarized into three parts: aperture, shutter, and sensor.
The aperture determines the amount of light by the wider or narrower opening of the lens. The amount of light affects the field depth of your image.
The shutter speed determines how fast or how slow your camera takes the photo. This also determines the length of exposure as well as the value of blur in motion cameras. A slow shutter absorbs more light and captures motion. Fast shutter absorbs less light and freezes the moving scene.
The sensor is determined in a measurement called the ISO. This measures the amount of light caught by the sensor and, with every increase in ISO, will also capture digital noise.
What about exposure?
Frankly, it annoys you to capture a photo and get a dark image. However, an overexposed photo is annoying too. Understanding exposure will help you capture a photo and present it in an ampler light setting.
To control the exposure setting, you will be tweaking on the shutter speed, aperture and ISO to gain the best lighting of every photo. While light is controlled by these three components, this will also affect motion blur, noise, and even the depth of field.
What about metering and histogram?
Metering determines the amount of light present in a scene. There are four metering modes: average, center, spot, and partial. They are applied to different scenes, which you will learn more when you engage yourself in a photography course.
The histogram is simply the mathematical translation of light exposure in your captured image. This is to tell you more about how it depicts the scene without being affected by the type of screen your digital photo is presented.
