How to take a photo like a pro with iOS 8 iPhone camera
iOS 7 has great camera features already but iOS 8 give you more. The new features in iOS 8 camera app are: a manual auto exposure adjustment, a self-timer and a time-lapse video mode. This article will only discuss one of those. It is time to take a photo like a pro with iOS 8.
Manual Auto Exposure Adjustment of iPhone Native Camera App
Exposure is a parameter to determine the amount of light that could reach the camera. It’s determined by three other parameters:
- Aperture: the size of opening camera lens. In the digital camera we can see it when we press the shutter camera button, a hole in your camera lens will be opened and make the camera sensor capture an image. The bigger hole of camera lens, the more light will enter, and reverse.
- Shutter-speed: shutter camera determines when the camera sensor will be opened or closed so that can take the light, but shutter-speed refers to how fast this shutter camera is opened.
- ISO: is a parameter which determines how sensitive a camera sensor towards the entering light.
Well, the aperture of iPhone it’s a fixed size, so that cannot be used to change the exposure. However the shutter-speed and ISO can be set to adjust the exposure. The bad news is that we cannot do that by using the iPhone native camera app only. Exposure feature of iPhone native camera app has been set automatically (Auto Exposure=AE). We can adjust the exposure of image we are going to shoot manually but we cannot change the parameter inside(shutter-speed and ISO) because it has been set automatically.
How to use manual auto exposure on iPhone native Camera app
- Launch your iPhone camera.
- tap once on the object that you’re going to shoot and you’ll see the yellow square with sun icon on its side.
- Swipe the sun icon up if you think the lighting is less, or in photography term called under-exposed.
- Swipe the icon down if you think the lighting around that object is too over, or in photography term it’s called over-exposed.
- to reset the auto exposure, you can just tap it anywhere.
How to use auto focus on iPhone native camera app
