Good luck with RAW, Dave. Adobe Lightroom - like most modern Adobe graphics products - is now only available with a monthly subscription, and it's impossible to buy the up-to-date version of Lightroom. (I use a Mac laptop with 10.6.8 OS).

However, I managed to find and buy a CD of Lightroom 4 for a Mac with my old operating system - on eBay - and it works fine. There are alternatives to Lightroom, by the way.

I don't know how your Fuji operates - I've got a couple of Finepix compacts - but the Canon produces RAW files in a format called CR2. This is a Canon version of RAW which has to be converted into DNG (digital negative) format for use within Lightroom. So be aware of that,

The other point to note is that RAW files are fairly massive - around 50Mb each - and computer hard drive storage can get eaten into pretty quickly! The resulting JPGs produced from Lightroom are also between 10Mb-15Mb each, so you could just keep those and trash the original RAW files. I keep both, however, and store them on two separate 8Tb external hard drives - backed up immediately.
