CAM1017, given your exposure of f/8 and 1/800, why did you use ISO 800?
Unless I was expecting the eagle to fly aware unexpectedly, I would have gone to f/5.6, 1/200, and ISO 100. At the distance you were shooting, you should have been able to focus accurately so that depth of field would not be much of an problem.

Your correct in that ISO 800 was to high. It was less then 1hour till sunset and it was becoming very contrasty so I made a snap decision to go higher on the ISO. Thank you for your comments. :thumbup:

Interesting. I really don't want to pop for the MIII but was considering a factory refurbished when the IV came out. The other bigger issue noise at higher ISO levels. Did the comparison you mentioned cover noise comparison?
I did not do any noise comparisons at higher ISO's. I was surprised to see it and wonder if it may have related to other mistakes I may have made. Normally I would not expect to see it at that setting.

I went and searched for comparisons of the 6D to the MIII. One of the reviews showed examples of noise at various ISO settings and the 6d was better based on the test procedure they used.

I will stick my neck out on this one. ISO does not affect contrast, only the dynamic range. That is, how black are your blacks and how white are you whites. Adjusting that curve in post-processing affects the contrast.

The reason you see quite a bit of noise is that you are underexposed by about one stop. Noise is more prevalent in shadow areas of digital images. You might try spot metering next time, or with a little practice you will know to open up one stop with sky in the BG or to use +1 EV when sky is in the BG. In any case, always try to keep your ISO as low as possible and your shutter as high as possible when shooting wildlife. The closer to 1/2500th of a second with the proper exposure is best. Of course, when the light is what it is (low) then you must take another course of action but it will probably always be one of your second rate images and you'll be wanting another chance in better light to replace it with. This is always my goal; get a better image of that bird to replace the one I already have. You will see two years from now that this Bald Eagle shot today will be in the trash having been replaced by much better images taken under better conditions. This is always my goal.

Good advice. Thank you. :thumbup:

The image is underexposed (IMHO). I would definitely slow down the SS and reduce the ISO. Set the exposure to just over your focal length and utilize exposure compensation to determine you have desired settings. The histogram is your friend, so use it. This will help you get better at shooting in manual mode. I generally shot my RAW images using AWB and adjust in Lightroom. Oh, also, utilize Back Button Focus to get focus lock. Then you can recompose for composition.
I have this camera, and a 7D for backup. Now I only use my 7D for back up or with my super side lens.

nice photos. i have the 6d and at iso800, I hardly get any noise at all. I don't start seeing noise til 1600 and still very little at 3200. i really like the 6d at it has become my favorite camera.

Thank you for your thoughts. What I thought was noise I think it is related more to the way I sharpen on the camera and in the Aperture program on my computer. Went overboard in this area. When I start to use some common sense in this area my experience with ISO is like yours. So far I like the 6D and plan on using it mostly with the 24-105mm for general shooting and macro work with a 100mm lens. I have a 60D and plan on using the 100-400mm on it for my birding photography. One interesting thing I learned form this topic was to over expose a little when shooting a dark bird against a bright sky. Will work on that. :thumbup:

the 24-105 is a great lens!!! my friend has one and i have borrowed it to test it. very good and sharp!!!what my friend does is mostly shoot in av mode and turns exposure comp up +.75. his photos are always great. with it being a f4 lens, he shoots a lot with iso 640 and 800. i saw some shots he made of some bmx racing.....he purposely shot 2 stops under to get his shutter speed up. then used lightroom to bring up the exposure. he shot at iso1600, he had a little noise, but the photos were great.
look up serge ramelli on youtube for some free tutorials...he pretty much always shoots underexposed and then he post processes in lightroom and comes up with the most beautiful photos.
