Many fans were surprised when they realized that chances of getting a camera with a higher number of pixels are very low, so they’ll have to get used to the old and improved 8MP camera on the iPhone 6/Plus. But, while perfection doesn’t exist, Apple’s camera has some problems related to poor white balance, discoloured skin tones and low contrast, which fortunately can be corrected by using iOS’s camera tools.
The problem with white balance and purplish shade
White balance is a process that removes unrealistic colour casts and the white objects will be rendered white in the photo. A good camera takes into account the colour temperature of the light source and manages to copy and offer the natural shade of white. The iPhone 6/6 Plus have problems with the white balance and distorts some colours such as red and brown, which may appear purplish when photos lack a neutral tone. And iPhone 6’s camera needs white, beige or gray to obtain the right white balance.
This is how you can adjust white balance. There’s an application called Camera+ which costs 1 dollar, which will help you adjust the white balance manually. You will override your phone’s white balance and you’ll set a preset that will neutralize the colour when choosing setting such as candlelight, incandescent bulbs or fluorescent lights. There are other camera apps with which you can lock white balance to some custom setting by adding a white portion in your photo (any white object) and then pressing the lock button.
The problem with low-contrast images
When taking high contrast photos, the image sensors are incapable of capturing the entire range of brightness and the results are seen in the blown out highlights/shaded photos. iPhone 6’s new A8 processor takes the brightness values and lowers them to fit into a narrower dynamic range and this method is called local tone mapping. Under bright sunlight, the iPhone 6’s camera will produce low-contrast photos because the processor darkens the overexposed parts of the image and produces flat-looking images.
There is a solution to this problem, a one-touch auto enhance button – the magic wand icon, which is located in the upper left side of the editing screen.
The problem with false skin tones
The outdoors photos taken with iPhones’ cameras added pink or yellow to people’s skin, in sunlight. It’s a nice effect, but the skin might appear sunburnt. The camera tends to replace white with a fluorescent yellow which can be seen on a person’s face or neck.
To fix this issue, you can use iOS8’s control called exposure compensation with which you’re able to override your phone’s built-in autoexposure and you can make the image lighter or darker. An easier method is the enhance tool (magic wand) which replaces the unwanted shades of pink with the right natural skin colour.
