Eye experts say smartphones are changing photo rules

The proliferation of smartphones and their use has completely changed the way in which people go about their lives.

From doing their shopping on their mobile phone to storing thousands of songs, the devices have changed the world, for better or worse, including the way in which people take pictures.

This new phenomena was recently examined in a study published in the Journal of Vision, where vision scientists sought to ascertain why pictures on the small screen often appear distorted.

They found that perceptual distortions occur because picture takers do not take their viewing distance into account, suggesting that smartphones are altering the way in which people take snaps.

As a result of the study, researchers have proposed the use of longer focal lengths – around 100mm - to create content that is viewed on the small screens of mobile devices, recommending that shorter lengths such as 50 mm should be used for photo images used on larger devices, like a TV.

Author Emily Cooper of the Helen Wills Neuroscience Institute, University of California, Berkeley, said the research suggests that long-standing guidelines for how to select the best lens likely developed as a way to compensate for the shortcomings in the brain's ability to perceive the scenes shown to us in pictures.

"By better understanding how lenses affect our perception, we were able to provide significantly improved guidelines for creating effective pictures," she added.

Cooper and colleagues hope these guidelines will enable picture creators to have better control over how their photos look when viewed in different formats, particularly as there are many new innovations in display technology.

"With stereo 3D and high dynamic range displays becoming more commonplace, our future research will be focused on understanding the potential gains and pitfalls of these types of pictures and displays," she added.ADNFCR-1853-ID-801389521-ADNFCR
