50D, ISO-6400 and 400 ... light is nice! (pics)
Oct 29, 2008

The first picture, pretty much shot in a cave, is of a Tree Porcupine (ISO-6400 pushed); this fellow is indigenous to the regions of Bolivia and Panama.

The picture was taken at a camera setting of ISO-3200 and then pushed one stop in PP. Only chrominance NR was performed in DPP (slider at 10), Red Paw Hot Pixel Removal applied at 30 strength, and Neat Image (Photoshop Plug-in) was used to reduce only the high spatial frequency intensity noise. Used a 100-400 set to 400 mm lens, 1/8 second, f/11 and the camera setting was ISO-3200 (picture pushed exactly 1 stop to ISO-6400). Yes, there is some visible noise (and a little camera shake) but IMO the 8x10 print was very usable ... looked good up close and would hang nicely on a wall (well, only if you wanted to stare at a Tree Porcupine).

Here is a 100 percent crop of the the finished picture.

Now here is why "light is nice" ... a White Cheeked Turaco (African) shot at ISO-400, 1/500 second, f/11, 100-400 set to 400mm, no NR, just processed normally using Silkypix. AFAIC, for all practical purposes the noise out of the 50D at ISO-400 is non-existent.

Here is a 100 percent crop of the finished picture.
