Eight Things You Must Know About Your Smartphone Camera

The camera tech in today’s smartphones has grown exponentially. The camera quality of modern smartphones is now on the verge of competing with more expensive digital cameras. With great technology comes great terminology. But most people have a very limited information about camera specifications. which leads to their purchase decision based on the megapixel count of the camera, which by the way is one of the biggest camera myth of all time.

Megapixel : This is mainly the size of the image captured from a digital camera and smartphone camera 2 & 8 Megapixel : This is mainly the size of the image captured from a digital camera and smartphone cameraThis probably the first thing that comes to our mind when we talk about a smartphone camera. Megapixel stands for millions of pixels and an image is made up of tiny units called pixels . Higher megapixel count in a camera will result in richer and bigger image.

Basically, megapixel can also be termed as the resolution of the image . While higher megapixel means bigger resolution which is the indication towards better image quality which is not always true, as pixel quality matters more than the number of pixels.

Aperture (f/stop): It is the opening of a lens’ which basically controls the amount of light that can pass Aperture (f/stop): It is the opening of a lens’ which basically controls the amount of light that can pass. The second most commonly used term in the smartphone camera is aperture. It is a hole in the camera, just like the pupil of our eyes which controls the amount of light that can pass through the lens and the camera sensor.

Lower aperture value indicates the wider opening of the curtain of the hole and wider opening indicated towards more light that can pass through the camera lens and sensor. The aperture also regulates the overall sharpness of the image and also helps in achieving a shallow depth of field which we will discuss in details later.

Optical Image Stabilization (OIS): It helps in reducing the blur of the image Optical Image Stabilization (OIS): It helps in reducing the blur of the image
Image stabilization generally prevents the images from getting blurred or capturing stable videos. This technology uses the moving lens elements and a gyroscope sensor. OIS determines the camera movements using gyroscope sensor to counter the movement by moving the lens module sideways or up and down. This feature is very useful while taking low-light shots and recording videos. one thing to keep in mind is that this mechanism can only minimize the effect and cannot completely eliminate it.

Shutter speed: It controls time interval that the sensor of the camera is exposed to light Shutter speed: It controls time interval that the sensor of the camera is exposed to light
There are three main pillars of photography – shutter speed, aperture and ISO. The camera shutter acts similar to our eyelids that open and closes to let light enter the camera and capture the image. The speed is related to the time for which the shutter will remain open exposing the light on the camera sensor.

Shutter speed helps in controlling the exposure of an image which can further be related to the brightness of an image. The slower the shutter speed, the brighter the image. It is very helpful while shooting in low light conditions.

ISO: It measures the effectiveness of your camera image sensor ISO: It measures the ‘effectiveness’ of your camera image sensor. It is the measurement of how sensitive is your camera sensor to light. ISO can help you to achieve better looking photos even in low light. The thumb rule is the darker the light, higher the ISO. But cranking up the ISO in smartphone cameras can result in a relatively grainy looking image, which hampers the overall image quality.ISO stands for International Standards Organisation, which governs the image sensitivity rating for camera sensors.

Depth of field: It helps in focusing on the subject of the image Depth of field: It helps in focusing on the subject of the image.It stands for the area in an image that is in focus. For example, if you are taking a portrait image then the subject should be in focus, but this zone can vary depending upon the picture. If an image has everything in focus then it has the deeper of field and if an image has its foreground or only background in focus then it has a shallow depth of field.The depth of field is controlled by the aperture of the camera.

Flash: It is the source of light for your camera while shooting in low-light conditions.Smartphones are portable, In well-lit conditions, all the smartphones take good-looking pictures, when it comes to low light photography most of the smartphone camera fails and easy to use and the point and shoot nature of their camera has brought the digital point and shoot camera to an extinction.  Here comes the role of camera flash which helps in illuminating the subject in dark.

It have mainly two types of flash- LED and True Tone LED. LED being the cheapest technology and most commonly used flash mostly in budget and mid range of smartphones. amber LED, helps in maintaining the white balance of the image.True Tone LED flash is one of the best flash technology available in the modern high-end smartphones which is basically the combination of white
