A camera is a device/ machine used to produce an image either with sounds or without (visual/audiovisual). A camera is a major device that makes up a photographer without a camera, there can’t be a photographer.
Care of a digital camera
A digital camera is a digital device which should be properly cared for because it possesses some censors which are sensitive and can be easily damaged when exposed to harmful environment/ substances.
- Take care of the camera as the eye
- Prevent the camera from dust
- Prevent the camera from falling down (always use a camera strap)
- Prevent the camera from a liquid substance
- Keep the camera in a safe place and condition
- Always use the padded bag to convey your camera
- It is advisable for one person to use one camera.
DSLR- Digital Single-Lens Reflex
A DSLR camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film. The reflex design scheme is the primary difference between a DSLR and the other digital cameras.
As a beginner in photography, you don’t just go buy the most expensive equipment right away. Handling a camera for the first time, you don’t expect to be perfect already. At first, it is frustrating and if not so determined, you’ll be motivated to quit.
Exposure: Aperture, ISO and Shutter speed comes together to give a perfect exposure. Once you’re familiar with the exposure then you will be able to control the camera and take better pictures.
The ISO is the major source of light in the camera since photography is the art of drawing with light, which means ISO is one of the major exposure controllers to the camera. It is represented in hundreds.
The ISO determines the image sensor sensitivity to light
Laws of ISO
The higher the ISO, the higher the amount of light that comes into the camera, and the higher the noise.
The lower the ISO, the lower the amount of light that comes into the camera, and the lower the noise or the sharper the object.
Don’t forget that the ISO is the first and major source of light in a camera and it has the highest amount of light.
The aperture is similar to the pupil of the eyes.
Since the lens has a diaphragm that determines the amount of light that comes into the camera which is passing through the lens as a channel which can be either small or big which is measured by the F-stop which is represented by the F-numbers e.g F/2.8, F/5.6
Laws of Aperture
The lower the aperture, the higher the focus light that comes into the camera and the shallower the depth of field
The higher the aperture, the lower the focus light that comes into the camera and the sharper the depth of field
The aperture is the second source of light in a camera.
The shutter speed keeps the shutter open either for a longer period of time allowing more light into the camera and increasing the speed at which the mirror goes up and down to be called an image, or closing the shutter which reduces the amount of light that comes into the camera and reduces the speed at which the mirror goes up and down.
The shutter speed are represented in fractions 1/125, 1/30, ¼ and so on.
Laws of shutter speed
The higher the shutter speed, the lower the amount of light that comes into the camera and the sharper the image.
The lower the shutter speed, the higher the amount of light that comes into the camera and the shallower the image. I.e. the image tends to be a blur.
With these handling, a camera will be much easier. You can make use of the internet to learn more. The exposure triangle will give you a better understanding of all the laws.
