hack

Want to shoot insanely cool Matrix-style "bullet time" footage at home? You can do so with a single rig built out of relatively cheap components.

NASA spaceship engineer Mark Rober came up with a brilliant way to shoot eye-popping imagery using just a GoPro camera and a cheap ceiling fan.

CyanogenMod is sort of like Magic Lantern for Android phones. It's an open source, replacement firmware option for people who want to get more out of certain Android devices. And the most recent update targets the photographic community -- in a hands-free sort of way.

Older Sigma lenses that were designed for Canon EOS film cameras often don't work correctly when mounted onto a new EOS digital SLR, even though the newer bodies still use Canon's EF mount. If you're an owner of such a lens, you might have heard that you can send it in to Sigma's service center for them to rechip it in order to make it compatible again.

Did you know that those of you who are handy with electronics can actually do the rechipping yourself at home? Photographer Martin Melchior recently did this with his Sigma 70-210 f/2.8 APO lens, and says that anyone with basic soldering skills can do the same.

Nikon's D5100, D3100 and D7000 all come with their own video time limits that keep them well below the 30 minute mark necessary to keep from being classified as "video cameras." That's because, as we've mentioned in the past, video cameras are charged a 5.6 percent duty that the manufacturers would like to avoid.

The D5100, for example, will stop you from recording once you've hit 20 minutes or 4GB, whichever comes first. In all honesty, most videographers won't see a need to record videos any longer than this, but if you do, the Nikon Hackers have released a hack that removes this time limit from the D5100, D3100 and D7000.

If you're the proud owner of a Wi-Fi-connected digital camera, there's something you need to be aware of: your camera could be used to spy on you.

At the hacker conference Shmoocon 2013 last month, German security researchers Daniel Mende and Pascal Turbing reported on findings that Internet-connected cameras can easily be exploited and turned into spy cams.

Photographer Jesse David McGrady has a super simple trick for adding a hazy, ethereal effect to your photographs: wrap a plastic sandwich bag around your lens. It sounds ridiculous and silly, but the results you get are actually quite nice!

Here's a tutorial on how to capture an exploding water balloon in the precise moment the balloon pops, while the water still holds the shape of a balloon. I didn’t want to invest any money in laser barriers or something similar, so I built a very simple mechanism. It doesn't give me perfect timing, but it produces acceptable results.

Photographer Nick Fancher tells us that he recently came up with an interesting way of customizing the catch light in subjects' eyes. If, in your portraiture, you place white or black foam boards to control the amount and direction of bounce light, you can also use white and black gaffers tape to control what goes on in your subjects' eyeballs!

David Hobby over at Strobist shares a fantastic idea for photographers who would …

After shooting music events, Perth-based photographer Perry DeGennaro keeps the media …

When Milan-based engineer and photographer Andrea Biffi needed a constant source of power for his Canon 40D in order to shoot time-lapse photos over many hours, he decided to save some money by going the DIY route. Biffi turned a defunct lithium DSLR battery into a power supply unit that can be used with everything from a wall outlet to a car battery.

You can do the same thing at home, but you'll need a bit of engineering know-how to accomplish the hack.

Last week, we wrote on how you can use LEGO pieces to keep your lens caps on your camera strap when they're not protecting your lenses. A reader named Fearn quickly pointed us to a similar tip published over at Sugru at the end of last year. Instead of using camera straps, however, they suggest tripods as a sturdy way of keeping track of the caps.

Focus stacking is when you combine multiple photographs of different focus distances in order to obtain a single photo with a much greater depth of field than any of the individual shots. This can be done by turning the zoom ring on your lens, but this can be difficult to control (especially for highly magnified photos). It can also be done using special rigs designed for the purpose, but those are generally quite pricey.

Photographer and software engineer David Hunt recently came up with the brilliant idea of turning an old flatbed scanner into a macro rail for shooting focus-stacking photos.

After recently purchasing a Nikon 1 V1, Swedish photographer Sven Hedin decided to work on making the camera work with an external flash. Not just any external flash, mind you, but a vintage flash unit -- the kind that uses disposable bulbs.

For a fleeting, wonderful moment, it seemed that all of our Instagram popularity dreams were coming true. Released two days ago, the app Firegram used some automatic magic to get your photos way more attention than they would ever have gotten on their own. When Roi Carthy of TechCrunch tried it out on one of his photos he got a whopping 56 likes (%1500 increase) in no time.

Alas, if it seems too good to be true, that's because it wasn't meant to last. As of now the app has been "discovered" by Instagram and denied access to its API -- no likes for you.

Lytro's groundbreaking consumer light-field camera made a splash in the camera industry this year by making it possible to refocus photographs after they're shot. However, the cheapest model for the boxy device has a price tag of $399, and the reviews have been mixed so far.

If you'd like to play around with your own refocus-able photographs without having to buy an actual Lytro device, you can actually fake it using a standard DSLR camera (or any camera with manual focusing and a large-aperture lens).

Back in October, Roger Cicala shared some first impressions of the Canon EOS M with us, and stated that he believes the camera is "a firmware update and a price drop away from being a great camera." While we haven't seen any major price cuts to the camera so far, a firmware update may be on the near horizon.

By "update," we mean "third-party firmware enhancement." Magic Lantern has announced that its firmware add-on will indeed work with Canon's mirrorless camera, and that they've begun the process of porting it.

Photographer Nick Cool came up with one of the strangest pieces of do-it-yourself camera gear that we've seen so far this year. He took an ordinary stainless steel sink filter -- yup, the thing that catches food at the bottom of kitchen sinks -- drilled various-sized holes through it, and stuck it into a filter ring after taking out the glass.

Samsung released the open source kernel files for its new Galaxy Camera late last week, something commonly done in the smartphone world -- at least with certain platforms -- but a foreign concept in the world of digital photography. This opens the door to all kinds of possibilities as hackers begin to peer into the cameras brain and dream up new possibilities for how it should work.

Developers are already talking about the possibility of introducing voice calling to the camera -- a feature Samsung left out of the camera, presumably to avoid cannibalizing its smartphones.

Here's a clever trick for if you ever need to print out a photo but find your inkjet cartridges low (or dried out): bust out your hair dryer.

Hardware security guru Joe Fitz has successfully hacked the WU-1a wireless mobile adapter to be compatible with the Nikon D800. "Why would anyone want to do this?" you might ask. Well, to get the same features, you could also buy a Nikon UT-1 Communication Unit for $470 and Nikon WT-5A Wireless Transmitter for $580 -- a combined total of $1050. The Nikon WU-1a, designed for the entry-level D3200, costs just $58!

If you have an old plastic kit lenses lying around, something that you are not using for anything serious, you can give it a new life as a macro lens by removing the front element.

When Google upgraded its Android OS to Jelly Bean 4.2 a couple of days ago, the company unveiled a new camera app called Photo Sphere that lets you shoot 360-degree panoramas by waving your camera around. If you've been dying to play with the app on your Android device running the older version of Jelly Bean, but can't bear to wait until 4.2 officially comes to you, this should be music to your ears: the new 4.2 camera/gallery upgrades and Photo Sphere have been successfully ported to Android 4.1.1.

Remember the remote Instagram printer called Instaprint? Although the Kickstarter fundraising campaign for the product raised nearly a quarter of a million bucks from 800+ backers, it failed to reach its goal of $500K, and we haven't heard much about the device since then.

If you regularly shoot in dusty or sandy environments, here’s a handy tip for keeping your camera clean: create …

For those of you who are desperate for Olympus to release a focus peaking feature for the OM-D EM-5, did you know that there's a trick you can use for "ghetto focus peaking"?

A French photographer named Nicolas recently found that the camera's "Key Line" Art Filter actually works quite well as a focus peaking feature. Simply turn on the filter, set your camera to shoot RAW+JPEG, and focus/shoot away. You can throw away the artsy-filtered JPEG files afterward, but the RAW photographs will be precisely focused thanks to the clever "hack"!

If you do any darkroom work, you probably regularly print contact sheets to peek at the positive versions of your B&W negative film strips. Did you know that your iPhone can be used as a quick an easy tool for this same purpose?

Dissatisfied with the way your smartphone photographs are turning out when the built-in flash is fired? When desperate times call for desperate measures, you can make your flash match the ambient light around you with the help of a colored gel. The flash is often just a tiny LED, though, so how do you comfortably "mount" the gel to your smartphone? Reader Todd Glidden has an answer: use an index card.

After months of dedicated hacking, Magic Lantern has finally been released for the Canon 7D. The new alpha version of the firmware add-on introduces a slew of new features to the camera, including focus peaking, zebra stripes, magic zoom, spotmeter, liveview customization, image review tweaks, and much more.

Don't have any more babies to transport? Old strollers can be repurposed as a way to wheel your camera gear from place to place. Just load it up with your camera bag, tripod, lighting equipment, and accessories, and you'll have yourself a mobile mini studio.

Have an old Polaroid camera lying around collecting dust? Did you know that you can use it for wet …

If you own an iOS device, you've probably noticed that the Camera Roll in the native Photos app doesn't come with any way to mark photographs as private. For this reason, the App Store features a large number of apps (both paid and free) designed to offer that feature, allowing you to choose what to show and what not to when someone else is flipping through your photographs. If you want an easy way to "mark photos as private" without having to download a special app (or pay money for a fancy one), Amit Agarwal over at Digital Inspiration offers this simple trick: crop them.

On September 22nd, more than 100 developers descended upon Berlin to compete against each other in building the best photo app they could within 24 hours. After a long, sleepless night and thousands of lines of code, 27 new photo apps were born. Here's a look at the top three that won the competition.

Photographer Kirsty Wiseman didn't want to shell out money for a real beauty dish -- she doesn't really need one -- so she built this funny-looking DIY beauty dish for a few pennies using a couple of Styrofoam bowls, a couple of cocktail sticks, and a piece of aluminum foil. After playing around with it, Wiseman was delightfully surprised to find that her gear hack actually produced decent results.

With the advent of Internet-connectivity and apps in cameraphones and digital cameras, images can now be shared with others in ways never before seen in the history of photography. Unfortunately, not all of the ways are positive. Some are downright creepy.

Take PlaceRaider, for example. It's a malicious Android app that hijacks your smartphone's camera, secretly takes photos of your life, and uses those images to reconstruct 3D virtual spaces of private locations.

Ireland-based photographer David Hunt recently came up with the brilliant idea of turning an old broken battery grip into a small computer that can be connected to his Canon 5D Mark II. After buying a Raspberry Pi computer for €35, he modified the battery grip and stuffed the computer inside.

Big bulky cameras can be pretty intimidating when they're used to photograph young children. For a cheap and simple way to make yours a little more child-friendly, consider using a PEZ candy dispenser as a fun, attention-grabbing hotshoe accessory.

Snapping a photograph while driving isn't the smartest, safest, or easiest thing to do. How then should one go about snapping pictures of the interesting things you drive past without breaking the law or putting people at risk?

Caleb Kraft of Hack a Day has one possible solution: remote-controlled cameras that attach to the side windows of a car.

For those of you who have never heard of Magic Lantern (or know it only as a 17th century image projector) as far as Canon HDSLRs are concerned, Magic Lantern is a firmware add-on that first appeared in 2009 for the 5D Mark II. Since then it has been ported to most Canon HDSLRS and, for years, it has been known as a hack that brave and/or curious Canon owners have added to their cameras in order to squeeze out more functionality -- in some cases a lot more. The risk, of course, was always stability.

Sebastian Guerrero, an independent researcher in Barcelona says he's discovered a way to force friendship with any Instagram user -- private or public -- by exploiting an Instagram server-side vulnerability. In one case, Guerrerro forced Mark Zuckerberg to follow his test account. Then Guerrerro sent him a message through a photo post, which would show up in Zuckerberg's photo feed of people he follows. Guerrero also used a test account to follow a private user without the required approval from the private user.
