Selective editing
One of the problems with the first version of Lightroom was its lack of selection-based adjustments. Any changes you made to a photo were applied to the entire image. For many photos, this wasn’t a problem—changing the exposure, color balance, or other tonal setting throughout an image made sense. But, if you had an image that had a perfectly exposed sky and an underexposed foreground, for example, you couldn’t selectively change the foreground without making the sky look bad.
To make those types of changes in Lightroom 1.0, you needed Photoshop or another image-editing application. You would edit the image out of Lightroom, and then have to deal with a second version (or third or fourth, depending upon how much you edited it) of a photo in your Lightroom library.
