How to import and view images in iPhoto


Last week we took a long look at iPhoto’s interface. Now that we’ve got our bearings, it’s time to use the application for something worthwhile. And what could be more worthwhile than adding images to iPhoto’s library and then viewing them? We’ll start with the traditional method of importing images—connecting your iOS device, camera, or storage media to your computer and copying images between the two.

Apple tries to make pulling images off your digital camera or iOS device as easy as possible. In the best of all worlds, when you string a USB cable between your Mac and your iPhone, iPod touch, iPad, or switched-on camera, iPhoto launches and offers to import images from the device. (I’ll provide the gritty details shortly.) I say “best of all worlds” because, while this almost unfailingly occurs when you use an iOS device, it doesn’t work with all cameras.

For example, I have no problem importing images when I attach my Nikon D300 DSLR in this way. But iPhoto refuses to recognize my Canon S95 point-and-shoot photographiser. Since there isn’t a universal “Hey, here I am!” technology that the Mac OS can use to recognize every camera that comes along, Apple must instead create updates that allow cameras to work with its software. Many popular cameras are included in these updates in reasonably short order, but some—like my S95—don’t make the cut.

Fortunately there’s a way around this. Inside your digital camera you’ll find a memory card. These days it’s some variety of SD (Secure Digital) storage card. If your Mac has an SD slot, as many now do, you can simply remove the card from your camera and slide it into this slot. By default, iPhoto will launch and offer to import your images.

A typical multiformat memory card reader.
If your Mac doesn’t have such a slot, or if you’re using a media card format other than SD (Compact Flash, for example), you can purchase a memory card reader from your local camera store or from an online outfit such as Amazon. Such readers plug into a Mac’s USB port, and many of them accommodate a range of media cards. Just shove the card into the appropriate slot on the reader, and iPhoto will launch and prompt you to import the images from the media card.

PhotoStudio 6 is powerful photo editing software featuring an array of advanced tools, filters and special effects inside a very friendly user interface. (By the way, if you’d prefer that iPhoto not launch when you connect a camera, iOS device, or media card, do this: Launch iPhoto; choose iPhoto > Preferences; and from the Connection Camera Opens pop-up menu in the General tab, choose No Application.)

And now for those import details. You’ve plugged your iOS device, camera, or card into your Mac. iPhoto launches and a progress bar appears. When the progress bar disappears, an Import pane takes up the majority of the iPhoto window. On the top-left of the pane you’ll see the name of your iOS device, camera, or memory card (CANON-DC, for example) and a date range derived from the timestamp of the first image and the timestamp of the last. Below this name is an Add Event Name field, along with a Split Events option. As should be pretty obvious, you can add a name for your event—Toga Party or Grunion Bake, for example—rather than having iPhoto create a series of Untitled Event entries, followed by their date.

iPhoto's Import pane.
When the Split Event option is enabled, iPhoto will create events based on the Autosplit Into Events setting in iPhoto’s General tab (found in iPhoto’s preferences). (The choices are ‘One Event Per Day’, ‘One Event Per Week’, ‘Two-Hour Gaps’, and ‘Eight-Hour Gaps’.)

Thumbnails of the images occupy the bulk of the Import pane. If the device contains already-imported images, you’ll see an Already Imported row that displays small thumbnail images of those pictures. Below that area is New Photos, where pictures you haven’t imported appear.

(Note that this area is confined to thumbnails. Double-clicking an image doesn’t expand it to fill the window. If you want to see a larger thumbnail image, use the Zoom slider at the bottom-left of the window.)

To the top-right of the pane are two buttons: ‘Import Selected’ and ‘Import X Photos’ (where X is the number of photos on the camera or card that haven’t already been imported). To import all of the unimported photos, click Import X Photos. To import just some of them, Command-click to select images noncontiguously (or Shift-click to select everything between and including the first and last selected images) and then click Import Selected.

When you do either of these things, a progress bar appears at the top of the window, along with a Stop Import button. You can click that button if you think better of your decision.


Making progress as iPhoto imports images.
When iPhoto finishes importing the images, a window appears asking whether you’d like iPhoto to delete the now-imported images from your device. Your options are ‘Delete Photos’ and ‘Keep Photos’. I follow the advice of the pros on this one and click Keep Photos. When I want to delete images from the camera I do it directly on the camera rather than depending on iPhoto to do it for me. I do so figuring that the camera knows how best to do this. With some cameras, I’ve found that the command simply doesn’t do what it promises.


Many people prefer to delete images on their camera rather than letting iPhoto do it.
Once you’ve made your decision about deleting images from the device, your imported pictures appear within the Last Import album, separated (by default) by event. Those events will also appear when you select Event in iPhoto’s Library pane, and all of the imported images will appear when you choose Photos in that same pane. If you took the images within the previous year, they’ll appear when you select Last 12 Months, too.

Elsewhere in the Library pane, you’ll see an entry for your iOS device, camera, or card. Next to a card entry you’ll spy an Eject icon. Click it and wait until it disappears from the pane, and you can safely disconnect the device. You needn’t eject iOS devices or cameras. Just detach the cable from your Mac or from the device.

If you have images that aren’t on an iOS device, camera, or card, but rather are just sitting somewhere on your Mac, dealing with them couldn’t be easier. Simply select the images and drag them on top of the iPhoto icon in the dock, or drag them into the iPhoto window, and they’ll be imported.

The Best Space Images Ever Were Taken by Apollo Astronauts With Hasselblad Cameras

The most iconic photos from the manned exploration of space come from the monumental Apollo project. But if you're not a camera buff or a space-history enthusiast, you may not know that nearly every single famous photo from that program was taken using Hasselblad cameras.

Known among photographers for their larger-than-normal film format and amazing optical qualities, the Swedish-based Hasselblad has also had a more than 50-year partnership with NASA. Astronaut Wally Schira carried the first Hasselblad used by NASA, a 500C camera -- which he had purchased at a Houston photo supply shop -- during his turn around the Earth in a Mercury rocket in in 1962.

Subsequent Mercury and Gemini astronauts also used Hasselblads, and each space shuttle flight took an average of 1,000 and 2,000 pictures with the cameras. Both NASA and the astronauts liked the Hasselblads for many reasons.

“The cameras were relatively simple to use, and film was preloaded into magazines that could easily be interchanged in mid-roll when lighting situations changed,” wrote Gary H. Kitmacher for NASA’s history office.

NASA asked Hasselblad for a modified version of their 500EL models to use during the Apollo moon missions. Known as the Hasselblad Electric Data Camera (EDC), these machines came with specially designed lenses and a glass plate that placed reference crosses on each image to make it possible to figure out the distance and heights of objects in the photos. The EDC's photo plate was also coated with a small conductive layer of silver, preventing the buildup of static electricity that could result in a spark. Finally, the outer camera was painted silver to help maintain the temperature, and all lubricants had to be replaced to allow the machines to work in the vacuum of space.

Starting with Apollo 8, astronauts carried a Hasselblad EDC with them on their lunar journeys. Neil Armstrong and Buzz Aldrin each had one during their brief but historic romp on the moon on July 20, 1969. Subsequent men also took Hasselblads, 12 of which are now sitting on the moon’s surface, left behind to save weight on the return trip. Only the film magazines returned to Earth.

Pictures from Apollo allowed people all over the world to participate in the trip. Looking through the Apollo Hasselblad film reels is like perusing someone’s weird vacation slides. Except in this case, the vacation happens to be one taken on the moon. As an additional and somewhat related bonus, the state of film technology in 1969 provides definitive proof that the moon landings could not have been faked.

In honor of the 44th anniversary of Apollo 11’s historic landing, here we present a gallery of some of the best shots that astronauts took from the moon and space with Hasselblad cameras.

Microsoft releases disk images for Windows 8.1 beta upgrades

Microsoft Thursday released its Windows 8.1 beta as a disk image, making it more convenient to upgrade multiple devices within an organization or enterprise.

 

Windows 8.1 Preview launched Wednesday, but was initially only available from Microsoft’s app market, the Windows Store. Each Windows 8 or Windows RT PC or tablet had to individually download the massive upgrade from the store.

 

By downloading a disk image, then burning it to DVD or storing it on a USB flash drive, users can upgrade machines or devices faster or when they are offline.

 

The .iso files range in size from 2.7GB to 3.9GB, depending on the language and whether the upgrade is 32- or 64-bit. Microsoft has made disk images available in English, Arabic, Chinese, French, German, Japanese, Portuguese, Russian, Spanish and Turkish.

 

Once downloaded, the .iso file must be converted into bootable media—typically either a DVD or a flash drive—to upgrade Windows 8, Windows RT, Windows 7, Vista, or even the 12-year-old Windows XP.

 

In a note accompanying the .iso download links, Microsoft warned users that they would not be able to uninstall the beta if they upgraded using a disk image. The company has posted other information about upgrading in a brief FAQ on Windows 8.1 installation.
