Adobe just announced Photoshop Elements 9, and this is a very significant upgrade that does affect digital photographers, including nature photographers. It now allows us to do some things that make work easier for certain techniques, such as double-processing RAW (really an important technique for nature photographers - more below). I have been working with the beta for a few months as I worked on a book about it, Top Tips Simplified, Photoshop Elements 9.
I believe that most photographers using Lightroom and Photoshop Elements work on images more effectively and more quickly than any but the most proficient users of Photoshop. And they can do it at much less cost. Being able to work quickly and efficiently is important for most nature photographers, including me, because the joy of photographing nature is from photographing nature, not spending more time than needed in front of the computer.
Having a Photoshop program gives you access to layers. Layers are extremely helpful for adjustment layers, for doing cloning to fix problems with an image (such as flare), and to combine images for panoramics or double-processing of RAW. I discuss how to work with double-processing of RAW on my website at www.robsheppardphoto.com. This is really easy to do with Lightroom - simply make a virtual copy of the original file, then process one of the images to optimize bright areas, one to optimize dark areas, then send them to Photoshop or Photoshop Elements for combining into one final file.
In the past, this was not so easy in Photoshop Elements because you had no access to layer masks for layers with pixels (though you did get layer masks with adjustment layers). Photoshop Elements 9 changes that. Layer masks can now be used with any and all layers. That is a huge change and really opens up possibilities for things like double processing of raw, two-exposure images, panoramics and more.
While Elements 9 did not get the fill part of content-aware technology, it does have it for the spot-healing brush. You can now brush over a problem and have the program fill that problem area with detail that matches the surroundings (to be honest, this does not always work 100% of the time, but it works enough to make it very worthwhile - if you try it and find it is not working, change the size of your brush and try again).
There is now very little that Photoshop Elements 9 cannot do compared to Photoshop, at least for photographers, and it is in a more photographer-friendly interface (including such things as Guided Edit that actually guides you through certain processing steps). And at a price of under $100, it is a terrific value (especially compared to Photoshop!).
The fall color in the Photoshop Elements 9 interface above is a photograph of red maple near Cascade Falls State Park on the North Shore of Lake Superior in Minnesota. The North Shore is one of my favorite places to visit as it has great memories - my family used to go camping up there when I was a kid, and when I lived in Minnesota, I would try to get up there regularly to photograph and hike (or snowshoe in the winter). Near Lake Superior, the winter is actually milder (though that is a very relative term) than back down in Minneapolis/St. Paul (and a whole lot prettier!).
