Create collaborative online photo galleries

For most events, parties, family gatherings, and vacations, there isn’t just one designated photographer in charge of taking and sharing all the pictures. It’s more likely that photos from various people will end up sprinkled across online galleries, posted to social media sites, or circulated via e-mail.

Instead of each person uploading personal albums to a separate site or figuring out who’s on Facebook and who’s not, try creating a collaborative album online. Here are five resources for carrying on the togetherness online, even after the party is over.

Review: Nikon D7000 DSLR

With the release of the D7000, Nikon created a new category in its broad DSLR line. At $1200 (body only), the D7000 offers a mid-range alternative to the higher end D300s, and the slightly-long-in-the-tooth but more affordable D90 (released in 2008). A full complement of advanced and automatic features, new 16 megapixel CMOS sensor, new 3D color matrix metering, good low-light performance, full 1080p HD video, full-time autofocus in video and Live View, along with under-the-hood improvements make the D7000 an extremely appealing DSLR for enthusiasts and prosumers.

Basic features

Like other DSLRs currently on the market, the D7000 is equipped with manual, semi-manual, and automatic exposure options. Two custom setting modes and 19 scene modes round out your basic shooting choices.With a new 16 megapixel CMOS sensor, the D7000 (along with the recently released 16 megapixel D5100) offers the second highest resolution in the Nikon DSLR line, bested only by the 24 megapixel sensor in the professional-level D3x ($8000).

Use Automator to shoot a time-lapse movie

Movies created through time-lapse photography can be stunning. And for some people in the sciences they can also be a useful tool. While there are a variety of applications that allow you to create time-lapse movies of your own, none of them are built into the Mac OS save this one: Automator. The following workflow allows you to automate not only the shooting of your images, but their conversion into a movie.

Before you launch Automator, create a folder on the Desktop called Time Lapse. Now launch Automator and from the template sheet that appears, select Application and click Choose. In the resulting workflow window add these actions: Take Picture (found under Photos), Pause (Utilities), Loop (Utilities), Get Specified Finder Items (Files & Folders), Get Folder Contents (Files & Folders), Import Files into iPhoto (Photos), and finally, Run AppleScript (Utilities).

For the Take Picture action to work (and thus the workflow) you must have a camera compatible with that action. My point-and-shoot Canon S95 isn’t, but my Nikon D300 DSLR is (and I suspect many other DSLRs are as well). When you plug your camera into your Mac’s USB port and switch on the camera, this action will display your camera’s name, if it’s compatible. From the Download To pop-up menu choose Other and then navigate to your Time Lapse folder. If you’re concerned about your camera’s media card filling up during the shoot, enable the Delete Picture From Camera After Downloading option. Also, you’ll probably want to attach your camera to a power supply rather than depending on a battery that might drain before you finish the shoot.

Nikon's image authentication algorithm cracked

Researchers have discovered a flaw in the system used by Nikon professional digital cameras to ensure images have not been tampered with.

Normally, in high-end SLR digital cameras a unique and encrypted signing key is appended to an image when it is taken, which is verified in Nikon's case by its proprietary Image Authentication System. If an image is edited this key will be overwritten, an action that will be picked up by the software.

Review: Canon EOS Rebel T3i DLSR camera

The Canon EOS Rebel T3i with 18-135mm f/3.5-5.6 IS optional kit lens is a complete picture taking machine. The latest Rebel features an LCD that swings out and can be positioned at a variety of angles, full HD video recording, wireless flash control, a respectable continuous shooting mode, and the same high resolution, 18 megapixel sensor as its predecessor, the EOS Rebel T2i.

You can build an entire system around the T3i by purchasing additional lenses, but we encountered no problems handling common shooting situations with the kit18-135mm zoom lens. For about $1,200, you can have a versatile camera/lens combination that would serve most hobbyists quite well. The 18-55mm is still available as the kit lens, bringing the price down to less than $900. So if you have a tighter budget, it’s great to have that option.
