• Mountain Lion users will tweet links and photos directly from the Mac’s built-in web browser, as well as from iPhoto, or Photo Booth, with the new Tweet Sheet command.
• Eastern cougars (mountain lions) do not have a native, self sustaining population in New York State. They have been absent from this state since the late 1800s; however, there have been a few isolated sightings. Each sighting involved cougars that are not native to New York. A couple of sightings.
• Go from picture to picture while basking in full-screen greatness using the new filmstrip. More screen real estate means a bigger workspace for perfecting each shot or creating the most memorable iPhoto projects ever. And now with OS X Lion, you can swipe to and from other applications or Mission Control without ever leaving full-screen view.

Camera and Photos

If you have an iPad, iPhone, or iPod Touch, you probably know how much fun it can be to take photos and videos on your mobile device. Did you know you can access your photos and videos on your Mac as well? To get started, you should make sure you're familiar with the apps below.

• Camera for taking photos and video on your mobile device
• Photos for viewing and organizing media on your mobile device
• Other desktop tools like iPhoto and Photo Booth

Have more than one Apple device?

There are many benefits to using these apps if you have more than one Apple device. They're designed specifically so you can access your photos and videos anywhere (on your iPad, iPhone, iPod Touch, or Mac), no matter where the photo or video is saved.

We'll be using the iPad for most of the demonstrations in this lesson, but if you have another device, don't worry. The corresponding apps for the iPhone, iPod Touch, and Mac are fairly similar. The important thing is that you get to know some of the basic tools and features and come away with a solid understanding of what each app can do. Then you can explore the apps some more on your own.

Mountain Lion’s new Notes application may not replace Stickies—that old standby is still hiding out in the Applications folder—but it does way more. For one thing, it provides better tools.

Camera

The Camera app is your resource for taking photos with your mobile device, as well as HD videos that have high-quality picture and sound. It's designed to work closely with the Photos app, which lets you view, organize, and edit the media you've captured.

If you have one of the newer models, you can even take advantage of your device's front and back camera to photograph what's in front of you or take a self portrait instead. The interface is similar across devices, so you should be able to learn your way around the app fairly quickly.

Click the arrows to view Camera on each device.

Camera is not available for the Mac. However, you can still take photos with your computer (front-facing only) using an app called Photo Booth. We'll take a closer look at Photo Booth on the last page of this lesson.

Have more than one Apple device?

Your device's camera is more of a utility than an app, so syncing doesn't really apply here. You can sync your photos and videos, however, using a feature called iCloud Photo Sharing. We'll take a closer look at this option when we discuss the Photos app on page 4.

Getting to know Camera

As you already know, the Camera app is different on each device—but there are many similarities when it comes to basic tools and features. Use the interactive below to learn how to perform several common tasks in the iPhone version.

Front/Back Camera

Tap here to switch between the front-facing camera and the back-facing camera.

Take Photo

To take a photo, tap the camera button.

Alternatively, you can use the volume buttons on the side of your device. Some people find it easier to hold the camera steady this way.

View/Edit

Tap to view the most recent photo you've taken. Here, you can quickly share, delete, or even edit the photo (with options like crop, remove red-eye, and more).

Focus

The app is designed to detect and focus on faces automatically.

If you want to change the focus to something else, tap the area you want to focus on. A small square will flash on the screen, and the camera will adjust.

Options

Use Options to turn on a grid, or enable HDR photos.

On newer versions of the iPhone and iPod Touch, you can even take a panorama. Just tap the button, and move your camera across the scene (for example, a landscape or a street scene).

Insider tips

Once you know your way around the app, consider these tips for getting the most out of Camera.

Quick access to Camera

On the iPhone and iPod Touch, you can access Camera even more quickly using the icon on your lock screen. Just drag the icon up, and the app will open instantly—there's no need to unlock your device first.

Zooming in and out

To zoom in or out in the Camera app, use the pinch gesture. This option is great for taking close-up photos when you can't get close enough to your subject (like in a crowd, at a public event, or when photographing wildlife).

You may want to use this feature sparingly if image quality is important to you. Because Apple devices don't have an actual zoom lens, the picture will start to appear grainy the more you zoom in.

Taking screenshots

To take a screenshot on an Apple mobile device, all you have to do is press the Home button and the Sleep/Wake button at the same time. This will take a photo of what's on your screen—just like all the images you've seen throughout this tutorial.

Photos

What happens when you take a photo or video on your device? It goes straight to the Photos app. Photos is where you'll be able to view and manage of all your media—including miscellaneous photos and videos you've saved to your device (from an email, text message, or anywhere on the Web).

Iphoto Mountain Lion Pictures

You can use Photos to create slideshows, organize your photos and videos into albums, and share media in a variety of ways. You can even sync the app across devices using a feature called iCloud Photo Sharing so you can access your photos anytime. Check out Apple's overview of iCloud Photo Sharing to learn more about how it works.

Click the arrows to view Photos on each device.

Photos is not available for the Mac. However, you can still manage your photos and access iCloud Photo Sharing using an app called iPhoto. We'll take a closer look at iPhoto on the last page of this lesson.

Have more than one Apple device?

Use iCloud to sync your photos via iCloud Photo Sharing. To find out if you already have it enabled, visit your device's iCloud settings. Remember, you have to configure each device separately.

Getting to know Photos

As you already know, the Photos app is different on each device—but there are many similarities when it comes to basic tools and features. Use the interactive below to learn how to perform several common tasks in the iPad version.

View/Edit

To view a photo, just tap the one you want. The photo will open in full-screen mode, where you can share, edit, or delete it.

To navigate to another photo in full-screen mode, swipe left or right, or use the navigation bar at the bottom.

Albums

Visit Albums to organize your photos into groups. This is a great way to manage your photos and videos if you have lots of media saved to your device.

To create a new album, tap the + button in the upper left corner.

Photo Stream

Tap Photo Stream to access all your photos and videos across devices, including your iPad, iPhone, iPod Touch, and Mac—even your Windows PC.

Photo Stream will sync your photos automatically anytime you're connected to Wi-Fi. You just have to make sure you have thefeature enabled in iCloud—then you can access your photos anytime.

Places

Under Places, you can view your photos by location. Just tap a pin on the map, and a thumbnail of the photo will appear.

Slideshow

Use this option to start a slideshow of your photos. You can even choose what type of transition to use between slides, and whether or not to play music in the background.

Edit

Tap Edit to quickly manage your photos and videos. Here, you can share or delete multiple files by selecting more than one at a time. Alternatively, you can add the selected files to an album.

Photos

Photos (also known as your Camera Roll) is where the app stores all the photos and videos you've taken with your device.

Insider tips

Once you know your way around the app, consider these tips for getting the most out of Photos.

Sharing photos

Sharing photos and videos from the Photos app is easy. All you have to do is tap the Share button anytime you see it (like when you're viewing an image in full-screen mode). From there, you'll be able to share the photo on Twitter or Facebook or send it in a text. You can even assign the image to a contact or make it your device's wallpaper.

Editing photos

The Photos app also lets you edit your photos with simple options like rotate, enhance, remove red-eye, and crop. This is a great resource for correcting minor problems with your photos without having to switch to an advanced image editor.

To access editing options, tap Edit while viewing a photo in full-screen mode.

Your options will appear at the bottom of the screen. Remember to tap Save when you're done.

More camera and photo apps

Photo Booth

You can use Photo Booth to take fun snapshots of you and your friends. Just like the Camera app, it uses your device's built-in camera to capture photos. The difference is that it comes with a range of special effects for you to choose from. For example, you can apply a stretch, X-ray, or thermal camera effect. You can also use the app to take regular portraits without applying any effects.

Photo Booth is available for the iPad and Mac only.

iPhoto

iPhoto is the Mac equivalent of the Photos app. Not only can it be used to manage the photos on your computer, but it also gives you access to iCloud Photo Sharing, where you can view and edit photos you've taken on other devices.

iPhoto also comes with several other features Photos doesn't have, including Facebook integration and advanced editing. You can even use the app to create cards, books, and other printed materials from your photos. Just pick a template, and iPhoto will walk you through the process. When you're done, you can order the final product from its printing press.

iPhoto comes built into the Mac. A mobile version can be purchased for the iPad, iPhone, and iPod Touch.

In the App Store

Other mobile apps from third-party developers (apps that are supported by Apple but not developed by Apple) can be downloaded in the App Store. There, you'll find a variety of tools that can help you take, edit, and share photos. These include:

• Instagram for taking photos and applying filters
• Camera Awesome for taking photos and applying filters
• Adobe Photoshop Express for editing photos
• Adobe Photoshop Touch for advanced editing

It's possible it's caching thumbnails of all of your photos. Just a guess.

I love and hate iPhoto. Its got several issues that should have been worked out long before now. I wonder if there's going to be a Mac version of Adobe's Photoshop Album?

I think that it is likely that it is caching and confirm the contents of the iPhoto Library, to make sure nothign has changed.

I also think that it's caching all the photos in the Library. A bigger issue for me, with my 5.6 GB hard disk and 320 MB RAM, is that it needs a ton of memory to cache all those photos--iPhoto normally forces the OS to create 3 or 4 virtual memory swap files almost immediately when it starts up, chewing up a substantial portion of the ~1GB disk space I have available. iPhoto 2 didn't cache photos immediately, which made it a bit slower when scrolling (although not much slower in practice on my machine, since it's effectively just caching them in virtual memory rather than reading the files directly)--I wish you could turn caching off in iPhoto 3.

To speed things up IMMEASURABLY, 'View as Albums' and then option-click on just one of the fold down menus to collapse an album. All of the albums will immediately collapse, and you can then scroll through your albums via their textual names. When you find the one you want to look at, just click the arrow again to uncollapse it.
Since iPhoto isn't drawing all of your thumbnails as you scroll, it makes the app that much faster to scroll through.

You must all be right about thumbs caching & CPU usage : my iPhoto app is set to start by showing film rolls and my rolls are always closed at startup.
For a test I opened iPhoto and watched CPU usage by the 'top' command : it climbed to 60% for a second or two, and then went back to 0% and stayed there... so far with a Tibook 400 ! :-)
My guess is, iPhoto didn't need to cache anything at startup, therefore it had nothing to do.
I waited some time, then played with the views and options, and then got back to closed roll : the usage returned to 0% when in background.

$ sudo fs_usage iPhoto
shows that the app is pretty busy. iphoto needs to be running before fs_usage can catch the app.
you can fs_usage | grep -i iphoto to watch it from launch
