Karen,
If you're on the west coast you'll be spoilt for choice for photography!
maybe 40 miles from Fort William (west) is a place called Morar, there are some gorgeous white beaches here. Morar is also really close to Mallaig, a nice wee fishing village where you can get a ferry to Skye.
You're also quite close to the Cairngorm, especially the Aviemore valley. Rannoch moor is close by as well.
Before you go, look up the SRPS (Scottish Railway Preservation Society) website and check the timings and dates for their steam excursions - also google 'the jacobite steam train'. These trips will go over the glenfinnan viadcut ( the one used in harry potter) and will make for some awesome shots.
Theres tons more to explore up there, but i need to head off! Hope thats helpful!
