Aperture 3's slideshow authoring tool allows photographers to mix stills and video to create dynamic presentations. You can playback at full screen in Aperture to share with clients, friends, and family.

Typically, however, we need to move those presentations off our computer to other devices, such as an iPad, or to YouTube and other online sharing sites. Maintaining that high quality during the export process can be tricky. And if you're not mindful, you might be disappointed with the results.

Aperture Export Presets The Export dialog box in Aperture 3. You can go with one of these presets, but you may not like the final output.

In Slideshow mode, when you click the Export button in the upper right corner of the Aperture interface, Apple provides you with a handful of presets for various devices such at the iPod, iPhone, Apple TV, YouTube, 720p, 1080p, and Custom. The first thing iPad users will notice is there's no preset for them. You might be tempted to choose the 720p preset, but unfortunately that preset doesn't work on the iPad. iTunes won't let you copy the movie to the iPad. Plus you're stuck with 30 fps for your frame rate, witch is a bummer if you captured your video in beautiful 24 fps.

You could go to the next preset up, "MobileMe/YouTube" for standard definition output (640x360 at 30 fps). But I can tell you right now, you probably won't like the results on an iPad, or even YouTube for that matter. The audio will sound fine, but my images were consistently soft.

I decided to go back to the drawing board to see what kind of vido output I could squeeze out of Aperture. After a few adjustments, I was able to improve my results substantially, but it required a three additional steps. Here's what I did:

  • Create higher quality previews. Since I do use some Ken Burns effect in my shows, I decided that my default 1920x1920 previews might be compromising quality. Aperture uses your previews to create its slideshows. So I changed the Photo Preview (Preferences > Previews) to 2560x2560 at 9 quality. I then had to regenerate those previews at the new settings so Aperture could use them. I selected all of the thumbnails in my presentation, held down the Option key, and chose Photos > Generate Preview. This took a while for Aperture to regenerate the higher quality previews, so I took a break while the computer churned away.
  • Export Using the Custom Setting. My goal was to create a high quality master file at the frame rate I wanted. To do that, I needed to select Custom under the preset menu. I used H.264, 24 fps (to match the video in my presentation) at 1920x1080. Label this file "master" for both playback on your computer, but also for creating smaller versions for other devices.
  • Now Create Your iPad Version Using QuickTime 7. QuickTime 7 is in your Utilities folder. It gives you more flexibility for exporting than the QuickTime Player that is the default for Snow Leopard. After the movie is open, go to File > Export and choose Movie to QuickTime Movie from the popup menu. Click the Options button and make these selections -- Compression: H.264, Quality: High, Frame Rate: (your choice, I use 24 fps), Encoding Mode: Multi-Pass, Dimensions: 640x480 (or what ever you want), and Scale: Letterbox. For Sound, just make sure you go with AAC at whatever settings you want.

All of these steps take time to process, so make sure you have other tasks lined up to do elsewhere. Once your new movie is rendered, copy it to iTunes or upload to its online destination. On my iPad, I have both versions of the same movie: the Aperture preset for "MobileMe" and my multi-step version. The quality of my version is about twice as good.

After just having spent a week in Kauai with a Canon S90 in my pocket, I can tell you that this compact is a godsend on the road. The ability to shoot with a fast f/2 lens in low light and save the images in Raw means that I rarely miss a photo opportunity.

Now, with the just-announced Canon S95,a great camera gets even better.


Canon has added HD 720p 24 fps video, click stops on the back control dial, improved stabilization, enhanced front control ring, and a high dynamic range mode. These improvements address just about every nit I had with the S90. It's an upgrade that I'm going to get as soon as I can.

Managing Geodata in iPhoto 09

iPhoto 09 is a handy geotagging tool. This means that if your camera doesn't capture latitude and longitude information when you take the picture (and most of our cameras don't), then you can use iPhoto afterward to add this information... and more.

Using "Places," not only can you add coordinates, but the actual place information in plain English: such as Country, State, City, etc. The best part is, iPhoto does most of this work for you. I demonstrate how this works in the following movie.

This movie is from my training series, iPhoto '09: 10 Things to Know About Places . If you want to tap the full power of iPhoto 09, you might want to take a look.

Best Shaved Ice on Kauai

Best Shaved Ice on Kauai, originally uploaded by The Digital Story.

When in Kauai, you must have shaved ice... as often as possible. I like a little ice cream at the bottom. You can pay up to $5 for one of these treats, but if you go to JoJo's in Waimea, you can have the best on the entire island, and for only $2. The perfect refreshment after a hike in Waimea Canyon or a swim in the ocean.

Over on Blurb on the Digital Story, I just ran a short, informative piece about the Blurb Color Management Resource Center. If you want the color in your Blurb photography books to be on target, you might want to take a quick look.

Quick Brushes in Aperture 3

Quick Brushes are a great addition to Aperture 3. They are located in the Adjustments popup menu, inside the Adjustments tab. Quick Brushes are exactly that, when you want to make a specific adjustment... quickly!

Some of my favorites include: Skin Smoothing, Polarize, Sharpen, and Definition. Being able to apply these types of adjustments to a specific area of the image without having to worry about creating masks is a wonderful enhancement to the post production workflow.

In this 7-minute video, I walk you through a typical Quick Brush scenario. You can see a larger version of the movie (better for this type of tutorial) by clicking through to YouTube or going to the Podcast page.

Sea Turtle Detail, Kauai

Sea Turtle Detail, Kauai, originally uploaded by The Digital Story.

Even when the wind comes up, you can always find something interesting to photograph -- especially if you get a friendly sea turtle swimming by.

I used a Canon G9 in a Canon underwater housing to make this photo. The image was processed on an iPad using Photogene.

One of my favorite Off Camera Flash tricks is shooting framed artwork without getting those distracting reflections. 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.

In this video, recorded as part of my Off Camera Flash training title on, we review my work after putting this technique to the test.

If you like this kind of stuff, be sure to check out the rest of the title.

The 2,400 Mile iPad Test

I'm going to do something I've never done before. I'm leaving for a week in Kauai, and I'm not taking a laptop. I have my Lowepro Fastpack 250 packed with my camera gear, lots of memory cards, iPad 3G, Bluetooth keyboard, and the Camera Connection Kit. The MacBook Pro stays home.

Why? Because I'm tired of lugging a 6.5 lb computer everywhere I go when I could save myself 5 pounds with the iPad, plus have Internet connectivity anywhere there's a cellular network.

iPad with Keyboard Going iPad and keyboard only - no laptop for this trip. Click on image for larger version.

While traveling, all of my images will stay on the memory cards. I'll upload my favorites to the iPad as backup and for enjoyment. And if everything goes right, I'll spend my free time taking pictures and enjoying Kauai, instead of working on the computer.

Stay tuned, and I'll let you know how this works...
