I’ve added a new page about Getting Started in Lightroom – very basic stuff but dealing with some of the questions I had when I first launched it.
The other thing to remember is that you can get a free trial. Lightroom 30 Day trial. Try it. If you don’t like it doesn’t cost. You can also download the standalone lightroom exe from somewhere on the adobe site and install that for a trial period if you don’t fancy the creative cloud. Good luck finding it! Either way you’ll need to get your self an AdobeID. That doesn’t cost anything apart from the occasional email you will get sent from Adobe.
