The app that gives your photos a nice afterglow, so to speak, has just been updated to version 1.4.

That’s right: Afterglow 1.4 is here. The new update comes with a number of significant improvements to the app, which my colleague Christine has found to be “incredibly easy-to-use” in addition to being “fast when rendering filters and effects.”

Afterglow 1.4 introduces a new adjustment tool called Clarify. According to Afterglow developer Simon Filip, this new tool is “designed to really bring out the detail in your landscape photos.”

The new version of the app also introduces a new “before and after” comparison feature. While editing, just tap and hold on your image to see the original unedited version.

Pinch and zoom functionality is also added for shaped frames. Speaking of frames, two of those are added in the update as well.

In addition, the update brings support for sharing your images to Flickr and for using either of your device’s volume buttons to snap photos.

The latter ability, which was recently added to Flickr for iOS, is a welcome addition. But I’ve noticed that when taking pictures using the volume buttons, the unnecessary ringer volume overlay indicator appears on screen. Perhaps this will be done away with in the app’s 1.5 update, which is said to be due next month.

Optimized for iPhone and iPod touch running iOS 5.0 or later, Afterglow 1.4 is available now in the App Store as a free update or as a new $0.99 download.
