Macro Photos Shot Using a Smartphone and a Laser Pointer Lens

Last month we wrote about how the small focusing lens inside a laser pointer can be repurposed as a cheap macro lens for your smartphone. After seeing this project online, photo enthusiast John Coleman decided to give it a shot. To keep the lens secure against your phone, you’ll need something to hold it (e.g. a hair pin) and some tape to attach the holder to the phone. The photo above shows the super simple attachment Coleman created.

Find a $1 Macro Lens for Your Phone Inside a Cheap Laser Pointer

If you want to take Lensbaby-style selective focus macro shots using your phone, go buy a cheap laser pointer. Photographer Zaheer Mohiuddin writes that the lens inside laser pointers (the one that focuses the laser) works well as a macro lens for the tiny cameras found on smartphones. After taking the device apart and finding the small gem-like lens, simply attach it to your camera with some tape to start shooting close-up pictures.

Photo of Laser Pointer Through Rain Reveals Water Drop “Snowflakes”

On a rainy day recently, light painting photographer Jeremy Jackson was playing around with a green laser pointer when he discovered something interesting: all the out of focus raindrops in the photograph had a lined pattern in them — and each one was unique! These “water drop snowflakes” were found in all of the photos he took that day.

Anyone know what causes this phenomenon?

Laser Pointer Used as an AF Assist Tool

Photographer Adrian Onsen wanted to use the AI Servo autofocus mode on his Canon 40D in low-light situations, but found that the AF assist beam is only emitted once until focus is achieved rather than every time the camera needs to refocus. He then purchased a laser pointer from a dollar store, disassembled it to obtain a defocused beam of light, and attached it to the top of his camera. The hacked-together AF assist tool ended up working pretty well — Onsen was able to shoot sharper photos at a dance club without anyone noticing the extra light. To learn more check out his in-depth writeup here.

DSLR Mirror Vibration Shown Using a Laser Pointer

How much does a camera vibrate due to your finger pressing the shutter or the mirror flipping? Camera Technica decided to conduct a test by strapping a laser pointer to the hot shoe of a Canon 7D. They then filmed the red dot on a far wall against some text while shooting normally (i.e. pressing the shutter with a finger), using a remote shutter release, and finally with a remote shutter as well as mirror-lockup.

You might be surprised at how much movement the camera experiences even if the shutter is pressed carefully. Lesson learned: for the sharpest possible photos, use a tripod, a remote shutter release, and the mirror-lockup feature on your camera.
