Here’s a quick tip for if you ever have a hard time removing a lens filter from a lens (e.g. when it’s damaged): use a shoe. Simply take any shoe with a grippy flat bottom, press it firmly against the filter, and then turn it. It’s a super simple technique that should work every time unless the threads on the lens itself are badly damaged.
Thanks for the tip, Luke!
In the past week, two different lens dial camera cases have been announced for iPhoneographers: a Holga toy camera case and a more serious lens dial case. If you don’t want to shell out cash to add a lens dial to your phone (and don’t mind it looking ridiculous), you can make a do-it-yourself lens dial using a jar lid and random lenses scavenged from various devices. The dial is attached to the back of your phone using a suction cup, and can give you magnification on-the-go.
Major camera makers including Olympus, Samsung and Sony have all filed patents in recent days for liquid lens technology. Unlike traditional glass lenses, liquid lenses don’t have any moving parts. Instead, liquid is used to focus light, and different voltages are applied to the liquid to change the shape of the liquid, thereby controlling the image. In the video above, techie Ben Krasnow introduces the technology, and then shows off a device he made by ripping a liquid lens out of a USB webcam.
We’ve featured special gloves and mittens designed for photographers before, but what if your camera uses a touchscreen instead of physical controls? Here’s a video by Make’s Becky Stern showing how you can sew some conductive thread into your glove to make it compatible with capacitive touchscreens.

You don’t need to shell out money for a nicer camera or a special lens to play around with macro photography. In addition to freelensing and using your lens backward, you can also place an ordinary magnifying glass in front of your lens to enlarge the world. Graphic designer Clif Dickens shot these close-up photos using a magnifying glass and an iPhone 3GS.
Modern DSLR lenses don’t usually have aperture rings, and opening and closing the aperture is the camera’s responsibility. If for some reason you need to keep the aperture blades locked in a certain position, the “lens twist trick” can help you do so. Simply untwist the lens from the camera while holding the depth of field preview button.
One practical use for this trick is time-lapse photography. Cameras don’t always close the aperture to exactly the same size every shot, and the slight variation can cause a flicker in the resulting time-lapse video (a problem called “aperture flicker“).
A couple days ago it was discovered that iPhones, iPods, and iPads running iOS 5 have a secret panorama mode that’s hidden in the operating system. The feature can be enabled, but featured either a jailbroken device or knowledge in how to edit a particular iOS 5 preference file. Luckily for non-hackers, Redmond Pie has discovered an easy way to do this by taking advantage of iTune’s backup feature. This tutorial will teach you how to get the panorama feature unlocked in 5-10 minutes.
