The camera on a smartphone continues to experience development. From what used to have VGA quality, it has now been upgraded with a megapixel value equivalent to a digital camera. In addition, several modes on digital cameras are also owned such as macros, low light, to the effect of making bokeh.
With the latest technology, the comparison between photos produced with a smartphone camera and a digital camera will look the same when taken during the day. Conversely, if photographed at night you will see the difference. Not many smartphone vendors can produce good photos in low light conditions.
Actually, there are tricks that can be done so that photography in low light conditions can look slick. Quoted from wikiahow.com, following Low Light Photography Tricks Using a Smartphone.
The simplest thing is to utilize light sources in the surrounding environment. For example, street lighting, shop lights, car lights and more. The more light that can be captured by the camera sensor, the noise (spots) in the photo will be minimal.
You can also edit it with the application and add filter effects to reduce the noise effect. But the most important thing is to recognize the camera capabilities on your own smartphone.
Most vendors now provide camera settings. For example, to get more light, can increase the ISO value. The higher the value the more light absorbed into the sensor. Just keep in mind, the higher the ISO value, the noise in the photo will be clearer.
You can also use the white balance feature to give a certain impression on the photo. White balance is set on cloudy to produce yellowish shades of sunset and sunrise or fluorescent which makes the photos look bluish. Under certain conditions, you can also use the flash on the camera to illuminate the object to be photographed.
The ability of a smartphone camera to handle low light conditions actually depends on the sensor and the aperture. The better or larger the sensor used, the higher the sensitivity to light. Then if the smartphone has a large diaphragm opening, the more light entering the sensor.
The size of the aperture in the camera lens is expressed in f / (…), such as f / 2.8, f / 2.2, f / 2.0, f / 1.8, f / 1.7, f / 1.5. The smaller the value of f / the greater the diaphragm opening.
