HDR iPhone 4 camera mode explained

The iPhone 4 camera is probably not the best shooter available on a mobile device, something which seems to be a regular occurrence with Apple devices. But there is a clever option on the handset which when used in the correct conditions can enhance images, and now we have an article looking at the HDR iPhone 4 camera mode.

The handset has HDR functionality built in and an article by Amy-Mae Elliott of explains the mode in detail. HDR stands for High Dynamic Range and uses exposure bracketing that creates a better representation of light and dark areas, compared to what the camera can capture using standard settings.

When used in the right way it can create an image closer to what your eye would see to that of the camera sensor. This is normally done by taking three images that are a standard one, an exposure which is one stop too light, and one which is one stop too dark. Then all three images are combined.

When the iPhone 4 is set to HDR mode it automatically recreates this process, and then puts the shots together to create one image with the best elements of each one. To turn the function on you just press the HDR icon at the top of the screen.

With it switched on the iPhone 4 will cleverly take the original image and the HDR version and save both to the Camera Roll. Settings can be changed so the iPhone deletes the original image, but it is useful to have both for comparison.

When using the HDR option you have to be careful you are holding the device still, and nothing in the frame moves, because as there are three images taken it will look blurred or cause ghosting in the image. HDR takes the extremes of light situations and creates the middle ground, which can be a problem if you are trying to capture striking contrasts.

The camera on the iPhone 4 copes quite well with color with nice saturated results, but using HDR can create images which are not true to life or vivid. The HDR option on the iPhone 4 can be a useful tool to have and used correctly will produce welcome results. The best way to get used to it is to take many images with and without it to see which works best.

Camera’s on mobile devices have come a long way in recent years, with even the amateur photographer amongst us can take striking images thanks to technology. Use the link above to see the various images with the HDR mode.
