Your smartphone is a great tool for taking pictures, but if you've ever tried to snag a portrait of someone, you know that they tend to be bland. Photographer Philippe Echaroux wanted a challenge, so he set out to take a solid portrait with just an iPhone and an inexpensive light.
There's no magic trick here. Echaroux is just solving the common problem with smartphone pictures: they need a lot of light to work. So, Echaroux took a challenge from a first-level photography class and decided to use a single light source -- in this case, a cheap lamp -- to light his subject very closely. From there, the process is as simple as shoving the light right in the subject's face in the right ways while snapping pictures and doing a little post-processing in Photoshop Touch. The end result is a pretty nice portrait considering how it was taken.
Sure, you want to know the basics of photography, and good picture posture to really snag a great image, but if you just need to get that nice portrait for your professional nameplate site or whatever, you don't necessarily need to go out and pay a professional. A smartphone (or any cheap camera), a lamp and a couple of minutes with an annoying light in your face is all you need.
