Thanks guys!
Vic, I don't use a filter, though I'd like to get some eventually (finances keep me from getting alot of things, actually) but I do play with shutter speeds to manipulate the effects/colors to a certain degree.
In the order that I posted the last three pics, using my Pentax K100D with a Pentax 18-55mm SMC DA lens, here's the info:
Image 1:
ISO: 200
Focal Length: 40mm @ f/5.6
Shutter Speed: 1/90 sec.
Image 2:
ISO: 200
Focal Length: 55mm @ f/5.6
Shutter Speed: 1/30 sec.
Image 3:
ISO: 200
Focal Length: 55mm @ f/5.6
Shutter Speed: 1/20 sec.
I would like to find a good mid-range lens for landscapes, since I have a huge gap between my 18-55 and my 70-300. I've been looking at the 50-150 and the price isn't all that bad, either.
Of course, if I had my way, I'd have all sorts of lenses and accessories!
