Adobe Systems has added three interesting features to its Adobe Photoshop Lightroom 4, which now allows users to organize and search for their photographs based on their metadata, such as the date and time settings from the camera and the location where the picture was taken. Whenever a camera with GPS enabled snaps up a photo, it also saves the geo-location data inside the image file. The 4th release of Adobe's Lightroom takes advantage of this hidden data to organize images based on geography and arrange them in a timeline. The new Lightroom also gives photographers the ability to brighten up their darkly lit photos and restore the balance between the light and shadows. In addition, photographers can now create portfolios dressed up as photobooks saved in a web-ready format that's quickly uploaded online and the link shared easily with potential clients.
