Adobe Lightroom has become more and more powerful over the years, devouring some of its sister software's territory, Photoshop, in the process. This landscape photographer still has to use Photoshop for these six adjustments, however.
My experience with Adobe Photoshop predates my time with a camera by several years. I learned Photoshop as a teenager and was familiar with many of its tools and functions before I used to it edit my own photographs. However, once I bought my first camera and learned to shoot in raw format, I decided I needed Adobe Lightroom too.
Lightroom started life a fairly simplistic (and clunky) raw editor and image library. I would do the basic adjustments to my raw files in the form of sliders and then I would export it and open up Photoshop to begin the more intricate editing. I would occasionally merge images for HDR in Lightroom, but that really was the limit. Now, however, Lightroom has a lot of the same functionality as Photoshop and a lot of power behind it. Nevertheless, I still don't do everything in Lightroom, opting for Photoshop for a multitude of tasks, as does Mark Denney, it would seem.
There is an interesting point under all of this. Many of the newer pieces of software for photographers and their post-production aim at being a holistic solution; they want to cater to all needs in one single client. The question is: how attractive to you is being able to do a complete edit on your images in one piece of software?
