For the next 2 months while I am away from home, I have to get used to a quite different approach to editing my images as I do not have Photoshop on my Macbook. I was hoping that Lightroom (which I have installed on the Mac) would do what I wanted, but that is not the case - - - and so I am attempting to get used to the Open Source Software GIMP and it's functioning. Most of the PS tools are there - some aren't - - - but the difficulty of switching from a familiarity and comfort level I have with Photoshop from hours a day working with it, is proving to be the same challenge that I had when I moved from years of using Corel Photopaint, to Adobe Photoshop a couple of years ago. Oh well - I am of the opinion that being put in difficult situations many times expands our abilities. Probably more than anything I am missing my handy and efficient specialty Windows programs like Irfanview, Porta, etc along with the custom PS actions I have created - that I use on a daily basis for fast conversion, layout and manipulation of images for web use.
