Singh-Ray Filters

I've been meaning to get more into landscape photography lately.  The Really Right Stuff tripod package I purchased recently along with lenses such as the Nikkor 10-24mm DX and 24mm f1.4G make nice landscape setups.  Something lacking from my kit: filters!  I just ordered a couple graduated neutral density filters (the Cokin P size) from Singh Ray.  What's a graduated neutral density filter??  Well, a normal neutral density filter simply acts like sunglasses for your camera lens and lowers the amount of light that passes through the sensor without altering colors (hence NEUTRAL density).  A graduated neutral density fades from the desired stop amount (often 1, 2, 3, or 4 stops) to clear.  This allows you to hold back the sky and the sun while leaving the foreground (ocean, field, whatever) unaffected.  You get a more balanced exposure with sky and foreground using them.  I also got a reverse graduated neutral density.  This guy is darkest in the middle, fades to gray on end, and is clear on the other.  This one is perfect for shots where the sun is right on the horizon and about to set.  Anyway, I just received the filters I ordered today and I have to say I'm pretty impressed with what I got.  Each filter has it's own little pouch (something I was not anticipating) and Singh-Ray included a 35 minute DVD on how to use and get the most out of filters in their lineup.  Another added bonus!  So far impressed with what I got so gotta give props to Singh-Ray. Hopefully I'll have examples to post here shortly....stay tuned. PS Singh-Ray has a pretty cool blog where a lot of photographers share their stuff and tips with filters here
