Here's 42nd Street & Broadway at 1:06 pm last wednesday. These are almost straight images from my new 40D shot full frame. I purposely aimed almost into the sun to see how the dynamic range would hold together. The camera raw processor in Photoshop CS3 automatically diddles with the histogram a touch... otherwise these are virgin images shot with my Canon 10-22mm at f9, 1/200, at 10mm.
There's lots of detail, nice contrast, hot color and plenty of dynamic range. Oh... I did use a polarizing filter which may have fed the camera flare a bit. I've got mixed emotions about filters on lenses. The engineers who designed these optics did not leave room in their equations for an additional piece of glass to be mounted micrometers in front of their lens array. So any filter will degrade... it has to. I'm always amazed by people who will buy expensive glass then mount a cheap UV filter "for protection" at the tip of the lens. How often have you scratched a lens, particularly when you use a lens shade? In fifty years of image taking I have never scratched a lens. So unless I need to add an effect, I won't use a filter.
Polarizing is an effect that needs adding. So, to get that deep color boost and flare reduction from a PF, I make the compromise. Actually the thing is doubly messed up by the way a polarizing filter works. You've got to twirl it, and that means getting finger prints on the front of the filter.. which further degrades the optics. Sigh....
All of that said, the images here are adequately sharp at 200 ISO. I still haven't mastered the metering of this new camera body, so I set the metering mode to partial for the day last Wednesday, I have to read the manual. I understand that the 40D has a true spot metering capacity which the 20D lacked. This should be a useful feature.
Okay, any comments?
