Before our full review next week, here’s a great little how-to guide on using geotagging in Lightroom 4. Adobe’s photo-editing and cataloging app has caught up with iPhoto and Aperture in its latest version, and you can now view any photos with embedded GPS co-ordinates on an in-app map. This means any of your iPhone photos can be browsed by location, which is a surprisingly useful tool.

But what if you want to reverse tag your photos? Say your camera doesn’t have GPS, but you have a track log recorded on a GPS device or with an iPhone app. How do you put this data together in a useful way? Below, Adobe’s Terry White shows us how.

One of the big things missing from Lightroom — Adobe’s excellent photo processing app — was printing. Not boring old printing where you have a big, expensive box in the corner of your office spit out endless sheets of paper until one of them is right. No, we mean remote printing, where you choose some images, hit a button and, a short while later, a gorgeous book appears on your doorstep.

Apple’s iPhoto and Aperture have had this for a while. Now, thanks to Blurb, the brand-new Lightroom 4 has it too.

Were you awakened this morning by the sounds of enthusiastic golf claps? It was photographers everywhere applauding Adobe’s release of Lightroom 4 for only $149 — half the price of Lightroom 3. Upgrading will run you less at $79, but price is only part of what’s new and noteworthy.

Adobe is set to launch a new service during the next few months called the Creative Cloud, which will allow users unlimited access to its pricey Creative Suite 6 package for just $49.99 a month. What’s more, Lightroom 4 will also be bundled in as soon as it’s out of beta.

That’s pretty terrific when you consider purchasing CS6 up-front will cost your around $2,000. In comparison, $600 a year is a bargain, and you get a lot more for your money.
