In a recent trip to Vegas I had a free day and decided to visit the Valley of Fire. A truly beautiful place, I was surprised by the variety of rocky formations and the vibrant colors of the valley. Guess they don't call it the valley of fire for nothing, lol. This is a 3-minute exposure on the Arch rock, a popular point among us, the tourists
Part of the warmth is due to the long exposure. The filters have a tendency to add a red cast. I don;t know if it it too much -- some photographers color correct the red cast in Lightroom. I did not, but the more I look at it the more the red/warm color is jumping at me, lol.
Ha, good point. When I arrived the park, on Dec 24'th 2010, they had already banned climbing on the rock, so thank god there was nobody trying to get a picture under the arch. On a separate note, because of the long exposure, the bodies would have probably disappeared anyway. This is the effect of having the shutter oped for several minutes, it empties the streets, lol.
I use a set of Lee 4x6 ND grad filters. Typically I wont carry the holder, for weight reduction. I'll just hold the filter in front of the lens. It works OK for exposures less than 30 seconds. They are not the most expensive, kind of middle of the road and I've been happy with the results so far.
