Hi there. Welcome to Camera Labs. Sadly like Thomas I don't use either of those programs. However, I've used just about everything else at one point or another.
It kinda depends what your priorities are. IMO none of the software titles do everything
well. Some people like Lightroom, it certainly has some good points in it's favour. ACDSee is good too, particularly for catalogueing purposes (it only allows relatively minor editing). I use it and love it. If you're really looking at editing software then you can't really go past Photoshop. Sure it's not exactly easy to get to grips with, the learning curve is very steep, imo. It is
the industry standard however. It's easy to find tutorials on-line and I bet you're local college or community centre runs classes in Photoshop. There are other programs of course, all claiming to be as good (or better) than Photoshop. They're not. Of course the biggest issue with PS is cost. The asking price is absolutely incredible IMO. Particularly for a home hobbyist
. Fair enough if you're making money from your images but for the rest of us the asking price is out of this world. For people like us there's Photoshop Elements which does about 80% of what a photographer is likely to do in Photoshop CS3 for a fraction of the price.
You pays your money...yadda...yadda...yadda.
there are free alternatives out there which work with varying degrees of success but none are quite as good as Photoshop. The Gimp is actually based on PS 2 I think. Faststone also make a good image viewer and catqaloguer, also free.
Hope some of that helps although I suspect you're even more confused.
Incidentally, whereabouts in Ontario are you?
