8 Important Things to know about Lightroom Collections

via Digital Photography School by Helen Bradley on 2/20/11

Collections in Lightroom are a key tool for organizing images. There are some benefits to working with collections and some things that it helps to know about working with them.

1. Collections: Smart or regular?

There are two types of collections in Lightroom, Smart Collections which are populated according to a filter which you define to identify images that you want included in that collection. For example, a Smart Collection might be defined as 5 star images which have a keywords that include the word Rome.

Smart Collections are dynamic so if an image no longer matches the filter you have defined for that Smart Collection it will be removed automatically from it. Likewise, newly imported or edited images which fulfill the criteria will be added automatically to that Smart Collection.

Regular Collections are collections that you populate with images that you choose to put in them. Images remain in these collections until you chose to remove them.

2. Sorting images in collections

You can sort images in order in a regular collection but you cannot reorder images in a Smart Collection.

3. Target Collection

You can set a regular collection – but not a Smart Collection – to be the Target Collection. There can be only one Target collection and to make a collection a target collection, right click on its name and choose Set as Target Collection.

In future, you can add images to the Target Collection by pressing the letter B. Press the letter B again to remove the image from the Target collection.

You can identify which collection is the target collection by the plus (+) symbol which appears after its name.

If you deselect the current Target Collection by right clicking its name and disabling Set as Target Collection then the Quick Collection, by default, becomes the Target Collection.

4. Gather images without duplication

One of the benefits of using collections to organize images is that the images in a collection can come from any location of your choice. You can create a collection of images from a number of different folders or even drives on your computer. Collections are simply a pointer to the original image, not the original image itself, so they require little additional space on your computer to store them. An image can belong to multiple collections and it will still only exist in one physical location on your computer.

5. Where is that image?

To find where an image in a collection is stored, right click on the image and choose Show Folder in Library to go to the folder in the Lightroom catalog. Alternately, choose Show in Explorer to see it in Windows Explorer (Show in Finder on the Mac).

6. Collections not in the Collections Panel

While most collections are listed in the Collections Panel, there are some collections that are not. In the Catalog panel you will find the All Photographs collection which is a collection of all the images that you have in your Lightroom catalog.

Quick Collection is a temporary collection that you can create as needed.

Previous Import is a collection containing the images in the most recent import – it changes every time you import new images into Lightroom.

Added by Previous Export is a collection of those images that were most recently added to the Lightroom catalog as they were exported from Lightroom. There is an option in the Export dialog that lets you automatically import exported images back into the catalog.

7. Three Handy Collections

There are three handy collections that are automatically created by Lightroom and which appear in your Smart Collections set. The Without Keywords smart collection contains every image in your collection that does not have keywords associated with it. It’s a handy reminder of the keywording work you still have to do.

Recently Modified is a collection containing images that have been modified within the last two days. You can alter the date range by right clicking the collection, choose Edit Smart Collection and change the number of days listed. You’ll see that by default it reads Edit Date… is in the last…. 2….days. You can change Days to Hours, Weeks, Months or Years and change the physical number from 2 to any number of your choice.

The Past Month collection is all the images that you have shot in the last month.

8. Managing temporary collections

If you often make collections that you only want to keep for a day or two to complete a particular job, either create a Collection Set to contain them or add the word “temp” to the collection name. This makes it easy to see collections you can easily delete to remove clutter from your Collections panel.

The Mobile Tsunami Is Near: Blame Netflix & Apple

via GigaOMTech by Stacey Higginbotham on 1/31/11

Think mobile data demand is big today, with 94 million smartphone shipped this year and 5 billion mobile subscribers? Well, Cisco ( s csco) says it’s going to get a lot bigger by 2015, with worldwide mobile data traffic set to increase 26-fold between 2010 and 2015, reaching 6.3 exabytes per month. That’s 75 exabytes annually by 2015 (What is an Exabyte?). Last year, I called it the mobilpocalypse, but this year, I’m going to say it’s a looming tsunami, driven by everyone’s favorite bandwidth hog — web video –and the proliferation of mobile devices. In short, we can blame this wave on Netflix on the iPad.

Cisco anticipates that in 2015, the average mobile user will consume 1,118 megabytes of traffic per month. For perspective, today the average mobile connection generates 65 megabytes of traffic per month, equivalent to about 15 MP3 music files. While the average growth is impressive, those megabytes will be spread across a wider number of devices, from tablets (big bandwidth hogs) to e-readers, which consume much less bandwidth, making it all the more significant. The Cisco study predicts that by 2015, more than 5.6 billion personal devices will be connected to mobile networks, and there will also be 1.5 billion machine-to-machine nodes — nearly the equivalent of one mobile connection for every person in the world. Cisco doesn’t give the current number of connections, but the GSM Association puts it at about 5 billion.

Cisco anticipates that mobile network-connected tablets will generate 248 petabytes per month in 2015 while machine-to-machine (M2M) traffic will reach 295 petabytes per month in 2015. The numbers are interesting because they are on opposite ends of the spectrum when it comes to data demand and profitability. Consumer video is in high demand thanks to devices such as tablets, but it’s also something operators are watching because they are worried it will clog their networks while not bringing higher margins. Meanwhile, much of the M2M connectivity will be small amounts of traffic, but extremely profitable.

The question operators must answer is how soon these dynamics will reach some sort of equilibrium, or perhaps, if those dynamics will reach an equilibrium. Cisco notes in a presentation that, “in 2010, global mobile data traffic experienced a 2.6 times growth for the third year in a row, despite a slow economic recovery, increased traffic offload, and the advent of tiered pricing.”

Operators are trying to cut back on data use, whether because their networks are overwhelmed or simply because they want to keep their nice margins on wireless data. However, that growth is still coming, and operators are undoubtedly trying to shape their customer base to ensure that a consumer-heavy subscriber portfolio doesn’t drag down their bottom line. So tiered pricing, pricing that ignores the reality of consuming more data at faster speeds, and possibly limits on what one can download in cheaper plans are all likely to make an appearance.

Crazy Stats (and One Chart) to Beef Up Your Mobile Broadband Reports

  • Mobile video is forecast to represent 66 percent of all mobile data traffic by 2015, increasing 35-fold from 2010 to 2015, the highest growth rate of any mobile data application tracked in the Cisco VNI Global Mobile Data Traffic Forecast.
  • Mobile traffic originating from tablet devices is expected to grow 205-fold from 2010 to 2015, the highest growth rate of any device category tracked.
  • Global mobile data traffic increased 159 percent from calendar year 2009 to calendar year 2010 to 237 petabytes per month, or the equivalent of 60 million DVDs.
  • Global mobile data traffic grew 4.2 times as fast as global fixed broadband data traffic in 2010.
  • Global mobile data traffic in 2010 was three times the size of all global Internet traffic (fixed and mobile) in the year 2000.
  • Smart phones, laptops, and other portable devices will drive more than 87 percent of global mobile traffic by 2015.
