Triggertrap is an ambitious app that enables you to control your iPhone camera, and with accessory dongle and connecting cable, your DSLR. Its functions range from the expected (cable release, sound trigger, and time lapse) to the impressive (eased time lapse and distance-lapse). It sells for $9.99 in the iTunes App Store, so expectations are high for its performance (as reflected in the user reviews on iTunes).

I tested Triggertrap on an iPhone 4S, and with a Pentax K-5 and Canon 60D. After my recent review of ioShutter, my expectations were "plug and play" for Triggertrap. But I quickly learned that this app is a bit more complex.

Triggertrap is an accessory for photographers who like to fiddle, experiment, fail, then ultimately succeed. You can do amazing things with it, like having the GPS in your iPhone measure your movement, and program the camera to release the shutter at a specified distance. That way, if you're documenting a road trip via time lapse, you don't burn a ton of useless frames while sitting in traffic.

But simple functions, such as using your iPhone as a cable release, have a degree of difficulty too. Suddenly I found myself reading the mobile manual trying to figure out delay settings and pulse lengths. If you like this stuff, you'll love the control that Triggertrap allows; if not, you'll feel the app is unnecessarily complicated.

There were some performance inconsistencies too, especially when controlling the DSLRs via the cable. Sometimes one tap would equal a single exposure, other times multiple. I double-checked my camera settings to make sure I was in single frame mode, but it didn't seem to make a difference.

For some functions, such as time lapse, this wasn't an issue. Everything worked great. But the sound trigger (Bang) and simple cable release were sometimes more of an adventure than I expected.

Bottom Line

If you're looking to create something out of the ordinary with your DSLR, take a look at the Triggertrap functions. For a $30 investment ($10 for the app and $20 for the cables), you can use your camera in ways you might not have imagined.

But, you if want a simple remote release with a handful of expected functions that doesn't require any fussing, Triggertrap probably isn't for you. It requires engagement, experimentation, and sometimes frustration before providing you with the rewards you're seeking.

I'm planning a project with it where I'll use the eased time lapse function with the StarLapse motor mount to create a new time lapse movie. I'll keep you posted on the results.

To 40mm or not? Canon's $199 40mm f/2.8 pancake lens seemed like a no-brainer to me. But some in our audience weren't impressed. I start out the show explaining why I think this little prime is just flat out fun.

Metadata-Smetadata: despite the adolescent title, I think adding IPTC information to your photos before releasing them into the wild is important. And I say why in the second segment.

After a week of shooting with the Canon 40mm EF f/2.8 STM lens,I have to say this is one enjoyable little prime. At half the size of the 50mm f/1.8, it focuses quieter, is built sturdier, and is ever bit as sharp.

The 40mm will focus as close as 1 foot. It's not macro (even though Canon says that on the side of the lens), but it is close enough for interesting compositions.

The pancake lens also performed well in the studio. I used it to take a series of product shots.

And finally, with the 40mm twisted into a Canon Rebel T1i, I crashed the Lowepro Summer picnic for some candid work. I also passed the camera around to see how others liked it. In the process, they took a photo of me.

I like to call this lens the "optical body cap" because it virtually adds no thickness to my 60D when packed in the camera bag. I know this type of lens isn't for everyone. But I'm having a blast with it. Currently they're available for $199 US.

For the May 2012 Photo Assignment, TDS shooters fired up their motor drives and captured the world moving around them. See for yourself in our gallery, Action. And which one will be the SizzlPix Pick of the Month?

Photo by Ron Boyd. "When I heard the assignment 'action,' the first thing I thought about was this photo captured at Bosque Del Apache. I really like the contrast of the two engaged in intense competition while the other birds are seemingly unaware." To see all of the other terrific shots from May, visit the Action gallery page.

Like many other MobileMe users, I spent part of Saturday pulling content off my little corner of the Apple universe and saving it to the computer. As of today, it's goodbye MobileMe, hello iCloud.

I was greeted with this message when opening Aperture.

Just One More Thing...

This morning, however, when I opened my Aperture library to work on the TDS Photo Assignment (to be published soon), there was this parting message: "Click OK to move albums you have published to the MobileMe gallery to the Albums section of your library to preserve them." Aww shucks! Apple will relocate my MobileMe galleries to Aperture.

By the looks of the progress bar underway now, this will take a while. But, what a considerate eulogy for an old friend.

How versatile is the iPhone 4S? Nick Fancher, an Ohio based photographer, posted a "behind the scenes" video of a fashion shoot he did with just an iPhone 4S and a reflector as a fill light. He edited the images with Photoshop Express and Snapseed. Take a look!

Giants pitcher Ryan Vogelsong had his stuff working, and hitters Melky Cabrera and Buster Posey did their jobs at the plate. The result: Giants defeat Clayton Kershaw and the Dodgers 2-0 to pull within one game of the lead in the National League West.

I was there in lower section 128, row 13 on the third base side with my Olympus OM-D E-M5 and Olympus 40-150mm zoom.

I parked the ISO at 1600 and used Aperture Priority to keep the zoom at the widest setting (f/4-f/5.6). When extended to 150mm on the OM-D, the effective power of the lens was 300mm because you double the focal length for micro four thirds. The high speed burst mode (9 fps) was a pleasure for capturing the action. And since the entire package was so compact, I was able to enjoy the game as a fan and grab a few photos when the action heated up.

Special Thanks to Hunt's Photo

As you may have read in earlier posts, I had two temporary review copies of the Olympus OM-D, but was having problems purchasing one for myself. I had orders placed with the typical big camera suppliers, and they kept getting delayed.

So I contacted the great people at Hunt's Photo & Video based in New England, US. I worked with Gary, who contacted Olympus US to see what he could do. Within a week my Olympus OM-D was on its way to me. The price was the same as what the other camera suppliers were charging, but the service was heads above. And yes, Hunt's offers free shipping too.

They have a wonderful newsletter that comes out every couple weeks with lots of specials. I use it to help keep up on the latest releases. You might want to try it yourself.

Thanks to Gary and the entire Hunt's crew for getting that Olympus OM-D in my hands so I could shoot this great baseball game at AT&T Park.

Whether you work with models regularly, or are contemplating your first shoot, this week's podcast includes "5 Don'ts" for these projects. These warnings were culled from many conversations with the models I work with for TDS workshops and other projects.

In the second story I talk about the winner from the recent World's Ugliest Dog competition. Why? Because an artistic handling of an "ugly" subject can lead to an impressive photograph.

And finally, SizzlPix is offering a 20 percent discount to TDS listeners... on any size or quantity. Listen in to learn how you can take advantage and get "sizzled" for less.

One of the many feature improvements in Aperture 3.3 is the White Balance tool. Among its enhancements is an "uber auto" button and three "filters" for different types of photos. Here's an overview to get you up and running right away.

The new white balance tool in Aperture 3.3 includes a "skin tone" option for your portraits. Photo by Derrick Story. Click on image for larger size.

White Balance Popup Menu

Prior to Aperture 3.3 your white balance option was Temperature and Tint. Now there are two additional choices: Skin Tone and Natural Gray. Plus, there's an Auto button, but I'll get to that a bit later.

• Skin Tone - a great choice for portraits. This new algorithm is designed for portraits. Simply place the eye dropper on a skin tone and click.
• Natural Gray - designed to correct color cast, but to also leave some feel for the ambient color in your image. In other words, it won't over-correct your photo. An example could be an underwater scene where you want to temper the blue, but not eliminate it all together.
• Temperature and Tint - this choice is best for color casts that are more extreme where you really need to get in there and move sliders around.

Auto Button

The White Balance brick also includes an Auto button. When you click on it, Aperture runs all three "filters" and you can choose your favorite version. Auto Skin Tone works best when Faces is enabled because Aperture will use face detection technology to fine tune the correction. I had good luck with it, however, even when Faces was not enabled.

What's fun about Auto is that once you run it, you can cycle through the 3 filters to see the different types of corrections, then choose the one you want to use. On this portrait, for example, the Skin Tone version is beautiful, but the Natural Gray and Temperature and Tint versions were a bit too cool.

Recommended Workflow

Apple has made white balance so easy. I recommend that you begin by clicking the Auto button. Then cycle through the 3 filters and choose the look you like best. You can then fine tune the color by using the slider for that filter.

Keep in mind that these corrections are brushable too. So you can further adjust the color in specific areas. I'll cover that in a future post.
