Here’s a shot I took with it today. The RAW image is definitely very pinkish-red, but as I was told, it’s not a rough job to correct for the additional red sensitivity. I think, because the red is so hot, I’m losing a little dynamic range in the normal regime as well, but as you can see here, it’s not a severe problem. Now if the weather will give me a break, I’ll give the camera a real workout on some emission nebulae!

Southern Pacific number 4449

I was looking west (obviously) from the north end of the church parking lot which itself is north of Bonnie Street, and south of Airport Road. I jockeyed around until I had the sun completely behind the radar housing, and then shot a few shots at different exposures, hoping that the 50D's dynamic range would catch the gradation in the sky; it did ok, but I still wish we had another couple of high quality bits of dynamic range. Maybe the next camera generation will go there.
