To open the Preferences panel, click iPhoto > Preferences from the iPhoto menu.

This tutorial focuses on the General Preferences tab. To open it, click the General button.

The first item on the General Preferences pane changes how iPhoto identifies your sources. By default, iPhoto lists the last 12 months of activity in your source menu. You can adjust that timeframe using the pull-down menu. Clicking the check box next to Show item counts will display the number of photos in each category in your source list.

The next option allows you to select what happens when you double-click a photo in an Event or Album. Based on your selection, iPhoto will either open the photo editing pane, or magnify the photo. You can also choose whether iPhoto rotates your photos to the right or left by clicking the appropriate button.

Next, you can choose where iPhoto edits your pictures: in the main iPhoto window, in full-screen mode, or in an application.

You can tell iPhoto which email application you prefer to use for sending your photos by using the Email photos using: pull-down menu.

You can also indicate how iPhoto should connect to your digital camera by choosing your preferred option from the Connecting camera options: pull-down menu.

Finally, you can tell iPhoto to automatically check for updates to the software (recommended) by checking the box at the bottom of the General Preferences pane.

First, choose the photos you’d like to send to iWeb. You can choose a single photo by clicking on it to highlight it (a yellow outline will appear around it). Or, you can choose several photos by holding down the Shift key as you click. You can also select an entire album by clicking on it in the source list on the left side of the iPhoto window.

Next, tell iPhoto to send your pictures to iWeb by clicking Share > Send to iWeb from the iPhoto menu, then choosing either Photo Page or Blog. iWeb will automatically open.

When iWeb opens, you’ll be asked to choose the design template you’d like to use for your photos. Select one from the list, then click the Choose button.

iWeb will open your new photo or blog page. From this window, you can manage your page and make any changes you’d like. When you’re ready to publish your new page to the web, click the Publish Site button from the toolbar at the bottom of the iWeb window.

First, choose the photo you want to email. To select a picture, simply click on it to highlight it. A yellow outline will appear around the selected photo. Note that you can only send photos from your library or an album, not ones that are in a slideshow, book, calendar, or card.

To open the email settings menu, choose Share > Email from the iPhoto menu.

From the email settings menu, first choose the size of the photo. Larger photos have higer resolution and better print quality, but they take longer for the recipient to download. While smaller photos can be downloaded very quickly, they will not have the same level of quality when printed.

Next, use the check boxes to indicate what photo information you’d like to include. You can have any Titles, Descriptions, and Location information that you have added to the picture in iPhoto included in the email, if you’d like.

When you have finished making your selections, click the Compose Message button. This will automatically launch a new message in your email program. From there, you can enter the recipient’s address, add a subject line, and send the email as you would normally compose any other message.

To print one photo from any album or event, simply click on the photo to highlight it. A yellow outline will appear around the photo. Then, click the Print button on the iPhoto toolbar.

On the Print menu, you’ll see that you have four different print style options. Clicking each will give you a preview. Choose the one you like best.

Next, choose the printer and paper settings that are appropriate for your computer. When you’ve made your selections, click Print to begin printing your photos.

You can also use these steps to print all of the photos in an album or event. Simply click that album or event in the source list of Events page to highlight it, click the Print button on the toolbar, and follow the above steps to print your photos.

Choose a photo from any Event or Album by clicking on it. Then, click the Edit button on the toolbar.

From the edit pane, you can easily zoom in or out of the photo. Simply move the slider in the lower right corner of the iPhoto window to the right to zoom in, and to the left to zoom out.

The Navigation window allows you to see which part of the picture you have zoomed in on. If you have zoomed in very tight on a photo, you will not be able to see the entire image on the screen. To view another part of the picture, drag the box on the Navigation window to the spot on the photo you’d like to see.

First, choose the photo you want to retouch. Click on any photo in an Event to highlight it, then click the Edit button to open the editing pane.

In the editing pane, click the Retouch button to open the Retouching tool.

You can adjust the size of the “brush” that is used to retouch your photo. Move the Size slider left or right. A circle will appear and will increase and decrease in size as you move the slider. Pick a brush size that is about the size of the blemish you want to retouch.

Drag the brush over the blemish you want to remove. If the blemish is small, simply clicking it with the brush a few times might do the trick. If more retouching is needed, move the brush back and forth over the mark until it has blended in.

When you’re happy with your retouched photo, click the Done button on the toolbar to save your changes and return to the Event.

First, choose the photo or photos you’d like to duplicate. You can choose one photo from any Event or Album by clicking on it to highlight it. You can choose multiple photos at once by holding down the Shift key as you click on each photo.

Click on the text beneath your new photo(s) to name them. Simply type the new title right into the field.

First, choose the photo you’d like to edit. Click any photo in an Event to highlight it. Then, click the Edit button on the toolbar. This will open the photo in the editing pane.

Click the Adjust button the toolbar to open the Adjust menu.

The Adjust menu has a histogram, or chart, at the top of it. This chart allows you to adjust the levels of lightness and darkness in your photo. We’ll start by adjusting the dark levels. To do so, drag the slider on the left side of the histogram toward the middle. This will darken a too-bright photo. If your photo is already too dark, leave this slider where it is.

Next, we’ll adjust the light levels. This will help brighten up a picture that is too dark. Drag the slider on the right side of the histogram toward the middle to brighten up the photo.

To perfect your picture, drag the middle slider left or right within the new dark/light range you’ve created.

If you decide you want go back to the way the photo originally looked, simply click the Reset button in the lower right corner.

Click Done on the iPhoto toolbar to close the editing pane and save your new photo.
