Inquiring minds want to know, right? On most Canon DSLRs, once you get over 100,000 shutter actuations, the risk of it failing increases (pro bodies more like 300,000). So how do you find out?

I just read a good article full of information on this topic titled, Finding the number of shutter actuations for your Canon EOS DSLR. The author, Shane, provides good background information on the subject, then lists links to freeware utilities that can help you determine the shutter actuations for your camera.

It's not something that I lose sleep over at night. But it is cool that I can find out if I want to.

Earlier this evening, I was part of a conversation on TWiP about what a great time it is for photographers. On my way home, a visual case in point.

There's a field of sunflowers near my house that I've been keeping an eye on. Leaving work late put me there right at sunset as I drove by. I pulled out the Olympus OM-D E-M5 and mounted the 40-150mm f/4.0-5.6 R Lens. The light was low, and I wanted to extend the zoom to tightly frame the shot.

Like we were saying earlier: it's a great time to be a photographer.

Take a look at the Olympus Micro Four Thirds Gear Guide for an overview of cameras, lenses, and accessories.

For the June 2012 Photo Assignment, TDS shooters found wisdom, humor, and direction in the words around them. See for yourself in our gallery, Signs. And which one will be the SizzlPix Pick of the Month?

Photo by Gerry Legere. "After driving around town looking for ideas, I first spotted two spots which looked promising very close to each other," Gerry wrote. "But then, as a bonus, the photo I decided to include also had the word Signs. This image features great colors, and a car in front, which sported a sign on its side that helped to repeat the theme." To see all of the other terrific shots from Jume, visit the Signs gallery page.

Participate in This Month's Assignment

The August 2012 assignment is "Street Scene." Details can be found on the Member Participation page. Deadline is August 30, 2012.

Please follow the instructions carefully for labeling the subject line of the email for your submission. It's easy to lose these in the pile of mail if not labeled correctly. For example, the subject line for this month's assignment should be: "Photo Assignment: August 2012." Also, if you can, please don't strip out the metadata. And feel free to add any IPTC data you wish (These fields in particular: Caption, Credit, Copyright, Byline), I use that for the caption info.

Good luck with your August assignment, and congratulations to all of the fine contributors for June.

In this Digital Photography Podcast: The Nokia 808 PureView camera phone has amazing specs, including 38 MP capture with a 28mm Zeiss lens. Then with PureView zoom, you can go up to 3.6X with the sacrifice being in megapixels, not image quality. Very interesting device, and possibly the best camera phone ever.

In the second story, I focus on a cool feature for photographers called AirPlay Mirroring. It's one of the 200 new goodies in Mac OS X 10.8 Mountain Lion. Using AirPlay Mirroring, we can easily share our photos and videos with small audiences.

And finally, do you know what those different album colors mean in iPhoto for iOS? They're actually a helpful organizational tool. All of this and more in this week's TDS podcast.

Do you know why iPhoto for iOS adorns your library shelf with albums that are blue, tan, and gray? They are actually organizational tools to help you find your images. In my Macworld article, Mastering albums in iPhoto for iOS, I explain in detail how you can put these albums to use on your iPad.

In the meantime, if you're curious as to what the colors actually mean, here you go:

• Blue - Albums created by iPhoto for iOS that contain pictures from your Camera Roll for from Photo Stream.
• Tan - Once you edit an image, or tagged it with a flag or as a favorite, iPhoto creates an Edited album and colors it tan.
• Gray - If you create an album in the Photos app on the iPad, or sync an album via Aperture or iPhoto on Mac OS X, those images will appear in a gray album in your library.

So yes, you can organize your pictures on an iPad.

One of Mac OS X Mountain Lion's most tantalizing features for photographers and teachers is AirPlay Mirroring. With just one click, you can share your computer screen with any HDTV wirelessly via an Apple TV.

I tested AirPlay Mirroring running Mountain Lion on a MacBook Pro 15" Retina display to my Panasonic LCD HDTV via a second generation Apple TV. The first thing I noticed is that there is no set up. I turned on the Panasonic, then chose Apple TV from the AirPlay icon in the top menu bar of the laptop. My computer screen instantly appeared on the HDTV.

I fine-tuned the image by opening Display Preferences and choosing "Best for AirPlay." Now, even the typography looked decent on screen.

This feature is terrific for sharing photography. My Aperture images looked very crisp onscreen. I played an HD movie that I had created, and the transitions were remarkably smooth. Every now and then there would be a momentary stutter on long Ken Burns effects, however. Audio is also piped through the Apple TV to the HDTV. I'm not sure I would watch a full featured action movie using AirPlay Mirroring, but for teaching and presentations, this is dynamite.

Once I was done sharing, I chose "Turn Off AirPlay Mirroring," and everything went back to normal on both computer and TV. This is a feature that will make it easy for photographers to share their work with family, friends, and small groups.

There are those images that I suspect have good potential, but require just a bit of work. My rescue tool of choice is Adobe Camera Raw 7.1 and Photoshop CS6. Typically, I can salvage a picture in just a few minutes. Here's a recent example of a 3-step photo rescue.

Step 1 - Open in ACR 7.1 and Apply the Graduated Filter

Using the Graduated Filter tool in Adobe Camera Raw 7.1

The big problem with this shot was that the top of the image was blown out from the setting sun. Since I shot RAW, I figured there was enough image information there, and the graduated filter seemed like the right tool to see what I have.

Step 2 - Open in Photoshop CS6 and Apply HDR Toning

HDR Toning in Photoshop CS6

After using the Graduated Filter in ACR, I thought I could balance the overall tonality a bit more. I used the HDR Toning tool in Photoshop CS6 (Image > Adjustments > HDR Toning).

Step 3 - Smart Sharpening and Save

Now all I had to do was apply a Smart Sharpening and save the photograph. By this point you're probably wondering what the original looked like. Here ya go.

And here's the final image.

The entire process took about 5 minutes.

If you recently purchased the MacBook Pro 15" Retina display, or another of Apple's latest offers, you probably qualify for the Up to Date Program.

It takes just a few minutes to complete the registration. Once you've been approved (usually within 24 hours), you'll receive a code that you can use in the Mac App Store to download Mountain Lion. Keep in mind that your order must be entered by August 24, 2012.

After I finished a day of recording at the lynda.com studio in Carpinteria, CA, I headed out to the beach for a sunset walk. It was very quiet that afternoon, and I had the area to myself.

I was traveling light. In my messenger bag I had the Olympus OM-D with a couple lenses, a wind breaker, and a hat. That's all I really needed for the next few hours.

Lobster washed up on shore.

I took off my shoes so I could wade around in the surf zone. The water felt wonderfully refreshing. And by doing so, I could get to the starfish and anemone.

I used the 14-42mm and the 40-150mm Olympus zooms on the OM-D E-M5 micro four thirds body. When I returned to my hotel room, I processed the images in Aperture 3.3.1 on the MacBook Pro (with retina display).

Sea Anemone

I did track a little sand back to the hotel. But even the nimble photographer has to get his feet wet now and then.

The Canon EOS M mirrorless camera has been officially announced. We've had some discussion on TDS about "is it the next camera for you," and I cover that conversation as the top story this week.

Then we get in to the Burger King Bust. Three employees at the hamburger shack photographed themselves standing in lettuce bins used for preparation. Then published the photo online. They were tracked down via geodata and fired.

And finally, the $25 wireless flash trigger from Cowboy Studio. What a deal! All of this and more on this week's TDS podcast.
