To celebrate our first TDS Off-Camera Flash Workshop this weekend, I thought I'd share a favorite tip: how to photograph reflective artwork with two flashes. This video is part of my Off Camera Flash training title on lynda.com.

The technique is simple. Set up two equal-powered off-camera flashes at 45 degree angles from the art. They will cancel out each other's reflections, but still illuminate the artwork. You can see the results of this configuration in this video from the course. Give it a try!

The design of the soft box is clever. A piece of translucent plastic is riveted to a black plastic back. You "bow" them to create the opening for the light fixture that hooks into place. You can set the soft boxes on a flat surface for table top photography or mount them on a light stand via the threaded socket on the bottom. At first you may say to yourself, "I could have made that!" But you didn't. Lowel did, and they are fun to use in practice.

Turn on the lights via the rocker switch on the power cord. At first, the twin fluorescent lamps won't seem that bright. Don't worry. Do something else for a few minutes, and when you look up again they will be much more intense. I've found they need a good 5 minutes to reach peak output.

Once they do, you'll notice that the light is soft and pleasing. I used two Ego lights to produce this video for Lowepro. For table top photography you can also use the included white reflector for additional fill lighting.

The Lowel Ego Light kit sells for $215. It includes 2 soft boxes with mounts, 4 bulbs, 2 reflectors, and a small sweep for tabletop photography. Don't get excited about the sweep - that, you could make yourself.

I like this set up. There are times when I prefer continuous lighting to off-camera flash. I just flip the switch, position, and shoot. For video they are a true blessing. And unlike "hot lights," the fluorescent lamps stay cool - particularly nice for portrait sessions.

Long exposure helps create the ghostly effect against a brightly lit background.

When you think about photographing Las Vegas, you probably see bright colors against a dark background. Right? Well, not necessarily. Whether it's Sin City or The City by the Bay, don't forget B&W. By removing color from the composition, you reveal a different place - the city behind the glaring lights.

The wispy effect is created by moving people during a long exposure. Photos by Derrick Story.

My favorite approach is to shoot in Raw, leaving all of my options available. Then, as I review the work on my Mac, I look for compositions than lend themselves to B&W. I test those candidates in Silver Efex Pro by Nik Software. And I always seem to come away with a handful that I like.

Twilight lighting converts well to B&W too...

So yes, Las Vegas is colorful. But it's also rich with interesting lighting and structures, which is perfect for B&W shooting.

One of the more interesting WPPI debuts was ICE Light, a hand-holdable daylight LED wand that makes it easier for the portrait photographer to hold the light source and shoot at the same time. The ICE Light is the result of a big name partnership: Designed by photographer Jerry Ghionis, and manufactured and distributed by Westcott lighting.

When set to full output, this device delivers 150 watts at 5200~5400k. It is bright indeed. It is also expensive. If you buy online, the kit sells for $499.

You hear video shooters say time after time, the best way to get great audio for your movies is to record it with a separate device, then sync it with the video in post. But sometimes that's easier said than done. Now, thanks to Dual Eyes by Singular Software, this process is easy.

For this video, I recorded audio with both my Rode VideoMic Pro mounted on a Canon 60D, and with a lapel mic connected to my M-Audio Microtrack recorder. I then used Dual Eyes to substitute the M-Audio track for the onboard recording. The sound was very much improved.

I learned about Dual Eyes during our recent recording of TWiP where Frederick Van Johnson remarked that he likes it. Since I had to shoot a video for Lowepro that next morning, I thought this would be the perfect test for it. The improvement was quite noticeable.

Basically, you record audio with both your camera and the separate recorder. Then, you use Dual Eyes as a standalone app to replace the audio tracks before importing into Final Cut Pro (or your favorite editor). The application compares waveforms of the two audio tracks and is able to sync perfectly.

I have to shoot in a very noisy expo hall this week for my WPPI assignment in Las Vegas. I'm certainly going to be using the separate recorder and Dual Eyes to milk the best sound possible from my interviews.

Dual Eyes isn't cheap: $150. But they do offer a 30-day free trial to give you a chance to test the software. If it works for me this week in Las Vegas that way it did for the Pro Messenger video I initially tested it with, I'm darn sure I'm going to buy it.

I touched down in Las Vegas on Sunday afternoon to cover WPPI 2012 at the MGM Grand.

An Olympus E-PL2 set to 1/2 second at f/16 at dusk. I wanted the traffic in the foreground to add motion to the image.

The Wedding & Portrait Photographers International event is enjoyable because of the stars it attracts and the energy generated by its youthful audience. In addition to blog posts and photos, I'll also record this week's TDS Podcast here in Las Vegas and share some of that great energy to those of you who are back home.

So, stay tuned. There's more to come.

It's one thing being able to connect your iPad to a projector and show your work. It's another being able to do it wirelessly. If you have a WiFi Epson projector, such as the PowerLite 1775Wthat I use for our TDS Photography Workshops, then you can use the free iOS app iProjection to display photos and presentations directly from your mobile device.

Imagine being able to walk around the room with iPad in hand, showing images from your camera roll and Photo Stream, or documents in the PDF, Keynote, PowerPoint or Microsoft Word format.

And what I really like about the Epson PowerLite projectorsis that they're about the size of a laptop. So you can transport the projector and the iPad in a standard size messenger bag... and be a very nimble presenter.

The trick to this system is that the Epson projector actually creates its own WiFi network. The module is built in to the unit. So, on your iPad (or iPhone for that matter), go to Settings > WiFi and select the adhoc network. Once you do that, iProjection will detect your iPad or iPhone, and display the content on the screen.

There is a setting in the menu system for the Epson Projector that allows you to name the network it creates. This makes it easy to find it if there are many other WiFi networks in your location. I do carry the iPad VGA adapter with me just in case. But so far, I haven't had to use it.

The Loupe tool in Aperture was one of the first "oh wow" features that caught photographers' attention. What's interesting, however, is that it's also quite useful, especially if you know the basic ins and outs.

By spending just a few minutes with this video from my Aperture 3 Essential Training on Lynda.com, you just might fall in love with the Loupe tool all over again.

"Danger, Will Robinson; danger, Will Robinson!" You look down at your camera and see Err 01 on the LCD. What does that mean? Why isn't it taking pictures?

Thanks to Rudy Winston over at the Canon Digital Learning Center, you can now have some clue as to what is going on. His article, Canon EOS Error Messages: An explanation and understanding, provides lots of insights about activity under the hood, and what many of those error messages actually mean.

If you shoot Canon, you'll definitely want to store this article on your mobile device.
