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 like to always have some gaffers tape handy at all times:
So we are gonna make a gaffer’s tape keychain fob [...] That right there is 40″ of gaff, effortlessly carried by default, at all times [...]
No, no, no. While duct tape may in fact be more manly, gaff is what duct tape wishes it could be. And it is what photographers use because of its holding power and ease of clean removal. Don’t ever mistake the two.
All you’ll need is a paperclip, a wooden pencil, and a larger roll of gaffer’s tape. Head on over to Strobist to read Hobby’s step-by-step tutorial.

After shooting music events, Perth-based photographer Perry DeGennaro keeps the media passes and wrist bands as mementos. Recently, however, he started realizing that he wanted a better way to store and display them. He had an old mannequin arm lying around, which he decided to put to good use by mounting it to his wall. The arm makes for an eye-catching display — every time he returns from an event, he simply hangs the lanyard from the should or wraps the wristband around the wrist.

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.
