OK, if you have Photoshop or Elements, here is a quick rundown on using it:

Ah, sorry I was late to see this!

There is a nifty tool in Win Vista/Win7 called the Snipping Tool which makes a very easy task of getting one "snippet", saving it as a jpeg, and then you can upload the jpeg to here.

XP doesn't have this, so Alt-PrtScn is still the "standard" approach.

Now, in XP getting it turned into a jpeg does require an image editor. Also, if you want to comine two "snippets" into one jpeg image, you will need an image editor.

I've been used to using Photoshop with layers for this type of thing, but a few months ago this question came up in our RAW Conversion Thread, and, in giving it some thought, I decided to put together a little tutorial for those who didn't have Photoshop but had Windows. This was before I knew about the Snipping Tool, in fact if you read the tutorial thread you will see it pop up toward the end and see it whipping up some interest.

However, if you have elements, you can do this using layers!

But the main body of this takes you throug the process of getting the screen capture and using Windows Paint to put out a jpeg, both of one "snippet" and then of a combined one. Check it out:

https://photography-on-the.net/forum/showthre​ad.php?t=974866

It sounds a bit complicated, but once you do it once or twice it's pretty quick.

And, you could do this with pretty much any imaging editor!

Thanks!

Ah, glad you saw it! Seeing screen captures of just your Lightroom histograms with the shooting info at the bottom cut out of the whole screen, having the 5D one and the 7D one pasted side-by-side or one over the other would be cool!

make sure the focusing screen is set to the right value for the screen you have installed...That can throw the meter off as well

I mentioned this earlier, too, but it certainly bears repeating... If you have the optional EG-S (higher precision/manual focus) or EG-D (grid) screen in the camera instead of the standard EG-A, there is a custom function that needs to be set or the metering will be skewed a bit.

A related, but more general observation... Canon has been known to "bias" their cameras a bit in the past. Perhaps all manufacturers do this to some degree or another, in part because "correct" exposure is a bit open to interpretation. A more specific Canon example, when I was shooting with EOS-3s and using Velvia ISO 50 slide film, I was in the habit of setting the camera's ISO to 40 as a standard practice. A lot of EOS-3/Velvia shooters did that. A lot of folks thought Canon's "standard" for their metering systems was slightly biased to "protect" highlights in slide film. I wouldn't be surprised if they did something similar in their DSLR models, and it might vary from one model to another.

How does the histogram look in Lightroom? From hour description, it almost sounds like the camera readout is faulty.

Any updates on this post? I just got a refurbed mk2 and am seeing the same consistent underexposure. I'd be interested to know when the OP decided to do.

What do you mean? What metering mode?

Don't use the auto lcd brightness in the sun, it will make you underexpose images. Set it to manual and two ticks right of the middle.
