I also know that people like guy say the diffrence. Now I won't say that he or I'm wrong, but on my camera the Canon had more DR.
Yes--I'll be happy to explain what I mean--but first basics...

First, I have NO IR filters--all my posted shots are unfiltered. It's just the profile, folks!

The chrome profile is here. It's not accurate, but it's way more balanced than the original Leica profile and will give magenta relief.

Don't forget to turn DOWN the saturation if it's too much (which is almost certainly will be )

I will always post profile updates in the sticky too..

Ok--now onto the controversial topic...

Please don't flame me--YMMV, IMO, etc... etc...

I nearly started a new thread called something like "M80 HDR device" I'm so blown away by the files.

But there's a lot of confusion here around this topic, so here's my take...

The latest Canon 1 series has at least a stop more leeway in the shadows than the DMR. Proof? Shoot a 1ds2 and a DMR side by side; open up the RAW file and push the exposure for the shadows. The Canon will win every single time, probably because of the noise floor.

This takes out your processing curve folks.

In actual practice, the DMR shot actually looks *more compressed* which people have mistaken for higher dynamic range (which it would be in film): you know, more contrast, better open shadows with less processing and so on. And the DMR has way more colour depth, and that affects a ton of stuff...

It's undeniably a LOT easier to process a DMR file than the Canon one, precisely because the Canon gives you way more choice in post-process exposure and tonal response.

In other words, you shoot your DMR, you see more more shadow detail with the same exposure? That's because the profile or your processing has moved shadows *up* into your monitor's visible range, not because it's *not there* on the Canon It's actually more compressed with DR.

Perhaps, just to be clear, I should call this exposure latitude; I'm not talking colour depth--which, as I said before, the DMR is way better than the Canon, but the Canon is all over the DMR in the ability to push or pull a shot.


That's probably the same thing as saying I can use the Canons at ISO 3200. I don't dare go above 800 with the DMR; that's two stops, folks.

The Canon has stuff in the low end and upper midtones the DMR doesn't get.

The DMR, however, has it all over the Canon in colour depth. This means, for example that the DMR has better gradations, micro-contrast and the Leica-ability to shoot right into the light without horrible banding, etc...

BUT--and this is a big but most DMR owners will understand...it's a lot easier to SHOOT the Canon. You need to nail nail nail the exposure with the DMR. So I can rescue highlights on a borderline shot much more easily with the 1ds2: again, you have to nail the DMR.

Now, enter the M8. It's much much much more like the Canon in the low end--at low ISOs, I can just keep pushing the exposure into places the 1ds2 doesn't even go! It's blowing me away guys... I mean it!

Something beyond it's ability to push to higher ISOs is happening here, and I've never seen it before.

So it's at least as good, and to my eyes, about a stop better than the Canon (and maybe more--but I could have just been tired and enthusiastic) in its ability to open up shadow detail without noise or artifacts, which is about a stop or a little more better than the DMR...

So it has the DNR of the Canon with the colour depth of the DMR. Wow. An easy-to-shoot and process camera (oh and that is sharp as razor blades!).

This accounts for the phenomenal (I mean it) amount of detail in places I expect to see shadowy messes--either with the DMR or 1Ds2.

Leica knocked this out of the park, folks! It kicks the DMR, which is not to say the DMR isn't fantastic; it is. So you know how much I'm liking the M8 now

Here's what I mean, given that pictures are worth, well, you know.

Here's an M8 shot at ISO 320. Direct sun reflecting into glass, bright sunny day, around noon, my profile, in C1. The exposure is on for the building.

The first shot is pulled half a "stop" in C1--just to show you highlight detail, but the second is pushed OVER 2 stops. Look at the wall--look at the *interior* of the building. Holy crap this thing is good...

The third shot is the colour detail, 100% crop, of the shot I posted above, which was shot directly into the sun. I can't do that with a DMR; I can't do that with a 1ds2. Only the M8 has the goods here.
