Here's the XMP sidecar file. You can use it to make the changes and look at what I did.

Thanks Stephen, can't seem to open the url ... I could be doing something basic that's off. Cheers.

It took me a few attempts to get it to show up right. You probably caught it before I was able to correct it. Right-click and save it. Then place it next to the .CR2 file, making sure they are named identically. In the Library mode, go to the image and go to /Metadata/Read Metadata From File...

Just uploaded the CR2 raw files to skydrive, hope this works:

The primary shot used here at 1/1000 sec:

A slightly more exposed 1/800 sec shot taken moments apart with the same set up as the primary:

Here's my work with the primary, using Adobe Lightroom. It took about five minutes:

Here's one I did when experimenting the camera when I first bought it. 24mm, 1/25, f/1.4, ISO 102000. All processing done with Lightroom. The light sources is from a street light about 150 feet outside the house. I could barely see her. The AF assist lamp from my 580EX solved the focus issue.
Love the film grain look... I had no flash mounted so my 35mm was strugling to lock focus and I am not sure it really did.

I did use a number of tools that LR offers, including adding grain. I add grain to nearly all of my images these days as it is; it helps images look more natural, as far as I'm concerned. It definitely helps with pattern noise.

"If printed at normal photographic resolution, the BT Tower panorama would be 98 meters across and 24 meters tall, almost as big as Buckingham Palace."

98 meters by 24 meters is about as big as an American football field. Isn't Buckingham palace bigger than that?

And just what is "normal photographic resolution?"

Canon General / Re: Why did you choose Canon?

I had been a Nikon owner since 1989, and I knew that that was the only brand I'd ever shoot. Fast forward to 2003, and I had a job that required a digital camera. I still thought that digital was a good five years away from being acceptable. I hated that the SLR's used a smaller-than-35mm sensor, and the point-and-shoots were so damned slow.

I was in Best Buy talking to a salesmen about this; particularly about the lens situation and how I would want a lens that offered wide angle coverage. To that point, it wasn't really possible. He was trying to sell me a 10D, but it was pricey, and none of the available lenses gave me what I was looking for. Besides, I preferred Nikon.

He did realize what I was looking for, after talking to me for a while. What's more, he had it in stock. Almost reluctantly, he pulled out a Canon 300D Digital Rebel with 18-55mm kit lens; the first lens designed specifically for APS-C format cameras. Not only was it speedy, with a lens that went somewhat wide, but it was $1,000.

I was almost shocked at the image quality from this camera. I had no idea digital photography had come this far.

So I accidentally switched to Canon, vowing to switch back someday. But Nikon took a very long time to catch up to Canon, who in the meantime released the amazing and very successful 20D. Once I had that 20D, I knew I was hooked, and I've never looked back.

Canon General / Re: refurbished Canon 5d mk iii

I'm not thinking about maximum profit, I'm wondering if there is a market if I decide to sell it.  I have about a week to return it, so having last minute second thoughts.  I wasn't expecting the pin hole in the bottom of the camera.  It doesn't affect the operation of the camera, but it says "I'm special" and may cause problems when trying to sell it.  I have read some online articles on Canon factory refurbs and it sounds like the odds are very good that there never was any sort of problem with it and if there was, odds are that Canon has fixed it.  A lot of people have bought refurbished and never had a problem.

But if something happens and I need money now or in the future and I am unable to sell it, I've just thrown away $2200.  I keep going back and forth on returning.  Especially when I see comments like "there are people(like me), would never buy a used-salvaged-item".

You bought a $3,500 camera for $2,200 and you're worried about the effect your $1,300 savings will have on the camera's resale value? Is that what you're saying?

I was hoping for a picture of the camera. ;)

EOS Bodies - For Stills / Re: 5D MARK III with 50 mm f/1.2 performence

I think you'd be better served buying a flash or two. Lenses are fun to buy, but you already have a 50, and you really should get a flash with a moveable head.

There would be no benefit to such a camera, whereas there are tremendous benefits to having a camera with video capability. One of the first ones, of course, is live view. That is, by far, the biggest innovation since the digital age began. Extremely useful capability, and once you have that, video is absolutely free.

"For arguments sake, that would give an approximate field of view of 90mm f/1.3. A nice portrait lens for the new system."

Just to clarify, it would be the approximate equivalent of a 90mm f/2.0 FF lens. You have to take the crop factor into account when comparing apertures as well as focal lengths.

You are right if yuo think about Dept of field, but in term of shutter speed the aperture it is still faster (must admit that with crop you have to use faster speed to avoid shake).
Diego

Actually, when you take noise into effect, you also have to decrease the effective aperture to get a valid comparison with a larger format. I can't do the math, but it's also roughly a stop.

That is, f/1.3 @ ISO 100 on APS-C really is comparable to f/2.0 @ ISO 200 on full frame. And f/1.3 @ ISO 100 on full frame would be comparable to f/1.0 @ ISO 50 on APS-C. (Roughly, with rounding, etc., etc., etc.)

This bunch is much, much smarter than the guys over on Model Mayhem. Or, at least, better at reading comprehension. ;)

Thank you again for the response!

So am I understanding you correctly too in that each camera will be calibrated differently, so to speak, and some 5DII's will have more shims than others depending on how they are manufactured?

Pretty much. Things get even more complicated when you have a 100% screen, like the Mk III. Lots of hand calibration.

The dust you saw was probably on the bottom of the focusing screen in the first place, btw. ;)

It's odd that it does not use CF cards. My 50D used CF cards.  For a pro that point is hard to overlook.


CF is obsolete.

I've finally seen a direct head-to-head comparison between the D600 and the 6D, and it's not as cut-and-dry as some people seem to think it is. In three areas that are very important to me, the 6D actually wins:

1. ISO range. The 6D has two full stops more high ISO settings at the top of the range. Based on my experience with Canon cameras, I expect this difference to show up in real world performance. This is an extremely important feature to me.

2. AF sensitivity. Yes, the 6D has a very disappointing 11 point AF system. It's irritating that Canon clings to these basic AF units. On the other hand, the AF is one stop more sensitive in low light than the state-of-the-art unit in the 1Dx and 5D Mk III, and two stops more sensitive than the AF in the D600. I love to shoot in ridiculously low levels of light, and coupled with the superior high ISO sensitivity, the 6D would seem to have the advantage in low light situations.

For my style of shooting, this is much more important than dynamic range, and Nikon's sensors lose that advantage at high ISO's.

3. Weight. I've been dying for a smaller, lighter FF camera from Canon. The 6D is a full 80 grams lighter than the D600 with the battery installed. This sounds like an awesome walk-around and backup camera. I intend to buy one to back up my 5D Mk III, as its specs are superior to the Mk II's in ways that are very important to me.
