I'm hoping to see a wedding dress in full sun with the highlight thing going. Seems like it rained all across North America. Come on Asia-Europe shoot us some wedding dresses Will be looking for them after the cereal. Steve

okay, i think the reason it does not play back is because the file written to the card does not have the three number prefix. i think this could be a bug.
I don't think it is a bug, from what you've said it seems you didn't follow the instructions in the manual. On page 78 the second bullet point down states
"Enter the required number of alphanumeric characters..." (Bold added for emphasis)
When I enter the required characters for both the 3 and 4 character settings, I have no problems with playback. You seem to have implied you entered no characters (or at least not the required number of characters); if you enter the required number do you still have an issue?

Thanks beewee. As much as some despise pet shots, his combination of black and white and the fine texture of his coat means that it is pretty revealing of faults with sharpness, WB and DR.

One of the interesting things I found is that when you enable the Highlight Tone Priority (C.Fn II-3) the lowest ISO you can select is ISO 200. This had me scratching my head and I had to reset all my C.Fn tweaks until I re-read the fine print in the manual. Not sure why they did that.
I have assumed the missing ISO setting is because the camera de-facto records at a lower sensitivity ISO setting but then processes the image to match the higher sensitivity setting except for the highlights. By de-facto I mean this might not be the actual way it works but this is what comes out in practice.

OK - so I just made a simple test of the Highlight Tone Priority mode. These 6 images were shot from my rear deck looking into the western sky about 1 1/2 hours before sunset in New Mexico.
The first three are with the function enabled and for the last three, its disabled. It was saved to "Autoviewer" right out of Photo Mechanic - no tweaking of the RAW images of any kind, save the JPG conversion.
To me, it looks like there are more details in the high clouds in the first 3 (enabled). The back of the house looks darker. In the second set of three, the sky seems more washed out, and the white stucco of the house is brighter.
Where they all set to the same exposure? The last 3 look a stop or more brighter overall, the trees are a lot brighter to match the more washed out sky.

I suspect that you are right. That would actually be a pretty clever way of doing it.

Thanks, for checking. you are correct. That setting was related to User setting2 and straight from the factory, User setting2 was empty therefore was the cause of this problem. Canon should have put a default value in there from the get go.
I took the new 1D Mark III for a little spin this morning to evaluate some of the corners of its performance envelope.
* All images originally shot in RAW
* No post processing at all - they were converted to what you see by PhotoMechanic and only hint at what a properly processed image would look like
* The hummers and bike riders were all shot at 10 FPS in an attempt to evaluate focus tracking. I wish I brought a longer lens for the hummers, and apologize if there are too many, but I've never been able to freeze them like this before (I don't usually do landscapes and wildlife - except the 2-legged kind)
* The interiors of the church and restaurant are high ISO - 1600 to 3200. No post noise reduction of any kind applied
* There is one of a white bench in sunlight. Since a wedding gown wasn't available, I used this to further evaluate the High Tone Priority mode.
Some of the images include comments to help you decipher what I was trying to evaluate. If someone has a particular need for the RAW image, please PM me and I'll try to get it up on YouSendIt.
My conclusion from this trial run is that I'll keep the camera ;-)
Here's the link - the JPGS in the show are large - a broadband connection is advised.

Yes, the aperture was set exactly the same for all, and the ISO was 200 for all. The differences you see are from the High Tone Priority function enabled in the first three. My thought on this is that its like applying curves to linearize the high luminance areas - probably useful for wedding shooters, but I'm not sure I would use it a lot.
What autofocus settings on the 1DIII seem to work best? On my 20D I've been using just a single AF point, but that may not work best on the 1DIII which I will have by Wednesday. I need to shoot an event with it on Friday. so I won't have much time to play around. I'd love to hear what settings people like best. Precise focus is more important than focusing speed for me. I'm often doing indoor work or low light work.
This is from the slide show I posted earlier. Its a grab shot of the interior of the La Hacienda restaurant in Old town Albuquerque. It was shot at ISO 3200.
Straight from the camera - no noise reduction or sharpening.

Gib,
I've got a 20D, and just got my IDMIII Friday. The autofocus options compared to a 20D are fantastic. But I don't think you'll get an answer to your question without a lot more detail about your shoot.
I shoot a variety of subjects, including studio stills, night time football, night time velodrome racing, triathlons, soccer... From my experience over this weekend, I can tell that each situation will have its own ideal AF options. I like how the 1D breaks out the options in aquisition, tracking, and sensitivity. But the "best" settings can only be determined by experimentation. Getting your's Wednesday? You've got to set up something on Thursday that's similar to your Friday shoot. Can't beat doing the tests yourself. If you can't do that, at least provide some more details on what you are trying to shoot.
I have performed some high ISO shots and comparison to the 1 Ds Mk II. I found this interesting cause the pixel size of the 1D Mk III and the 1Ds Mk II is nearly the same.
My conclusion: the 1D Mk III has a one stop advantage with respect to high ISO performance. Not more and not less. All comparison was done without noise reduction applied.
Will be looking for them after the cereal. Steve
