Camera could be one of the aspects that people look when they are choosing on which smartphone they would like to buy. Last year, smartphone manufacturers are focusing at the higher resolution camera being embedded on its smartphone. It was a megapixel race. Nowadays, it is about its aperture size, general build technology as well as the software which you can edit the image to be closer to the original or maybe even better than the original.
Thanks to bloggers at Photoblog Hamburg, we can know a little bit more about aperture size, shutter speed and ISO setting by providing us with a quick reference graph of the three of them as you can see from the above picture and how they are related to each other.
The aperture size has two effects on the photo. The larger the aperture size, more light can get in thus the better image that it is produced. A larger aperture size normally will be represented by lower number. Shutter speed is the time taken for the camera to capture what the sensor sees. On a sunny day, it should be kept at minimum to get a great picture as not to allow your hand to shake. When your hand shakes, you might get a blurry picture. However, if the shutter speed is too low, then you will get an overexposed picture. In darker environment, on the other hand, you might want to lower the speed as you want more light to get in.
ISO controls how much light ends up on the image. Low ISO means the least amount of light, vice versa, high ISO means more light. However, do note that high ISO introduce noise to the photo.
In dark environment, it is better to balance the ISO and shutter speed to get a picture which is not too noisy and not too blurry. In sport shots, you will need to set the shutter speed as high as possible since the athlete movement is happened so fast that you want to take it in motion without blurring them too much.
