Make sure you read and vote on Part 1 of the Great Debate: CCD vs. CMOS before venturing on to this test.

In the first installment, I published various sets of images, each containing one shot from the Leica M9 and one from the Leica M (Typ 240). The premise was to see if I could use basic post-processing techniques in Lightroom to make an image captured with a CMOS sensor (M240) match one taken with a CCD (M9). Many have stated that there is a defining “CCD Look” and that it was impossible to achieve this with a CMOS sensor, even with processing. So, I put it up for a vote.

So far, as of this writing, the results have been very interesting. Counting statistical margin of error, almost all of the images are running at a 50/50 ratio or very close to it. Of course, the images I first posted were taken in conditions favoring the M9: natural, directional light at lower ISOs. I didn't want the comparisons to be about dynamic range or low noise or artificial light performance. This was just an exercise to see if there was indeed a “CCD Look” and if such a look was only inherent in CCD-based cameras. Some have requested that I publish images under more challenging lighting conditions and with skin tones.

In this second (and final) round of testing, I'm putting forth a selection of single images shot with the M9 and M240. The test this time is to see if, without a direct comparison, the “CCD Look” can be identified. Please note that I didn't take comparison shots for any of these images. I shot normally, just with two bodies.  And, I didn't attempt to match to a particular look. Instead, I merely processed each file to my taste.

Without further ado, please cast your votes below. Yes, I know that there are a lot of images. I wanted to give a wide variety of scenarios to gather the most accurate data possible. Answers for both Part 1 and Part 2 will be revealed, along with my analysis, in Part 3.

Today, Leica Camera has announced the Leica M-P Correspondent by Lenny Kravitz for Kravitz Design. This set is comprised of the Leica M-P (Typ 240), Leica Summicron-M 35mm f/2 ASPH and Leica Summilux-M 50mm f/1.4 […]

Since the Leica M (Typ 240) was introduced, there's been an ongoing debate regarding the merits of CCD vs. CMOS sensors. From a technological and marketing viewpoint, Leica needed to make the move from CCD to CMOS in order to offer live view and better low light performance. Live view has facilitated the easier use of ultra wide-angle lenses and opened up the possibility of using alternative glass like the wonderful Leica R lenses on an M body. And while no one can argue the additional functionality and superior high ISO capability afforded by CMOS on the M 240, there's been a steady and growing opinion that the color and tonality from the M9, which uses a CCD sensor, is more pleasing. I can appreciate that the resulting images from the two cameras do indeed look different, and everyone has personal tastes. I've shot thousands and thousands of images with the M9, as I have with the M 240 since then. Personally, I find both results appealing to my eye and never really made a direct comparison as they are different tools that I used at subsequent times through my photographic endeavors.

Recently, I read some comments online that I found somewhat puzzling. Statements were made to the effect that it was impossible to achieve the same color and tonality with the M 240, regardless of post processing. While I didn't know whether this was true or not, I've worked in digital imaging for 25 years and know that almost anything is possible in post. So, I decided to challenge myself and test the theory. I was heading out West for a family ski trip during my daughter's Winter break and would be spending a couple of days in San Francisco before flying back home to Miami. This would be a perfect opportunity to take the first step, so I packed up my M 240 and an M9, along with some of my favorite lenses: 24mm f/3.8 Elmar-M ASPH, 35mm f/1.4 Summilux-M ASPH FLE, 50mm f/2 APO-Summicron-M and 90mm f/2.8 Elmarit-M, then started thinking about how to go about testing. The goal would be to shoot roughly the same picture with each camera, using the same lens. So, if I took a shot with one camera with the 24mm mounted, I'd swap lenses and shoot the same lens with the same settings on the other camera. Truth be told, this was not the most fun way to shoot, but I was on a mission to get as many comparisons under various conditions as I could and stuck with the program.

When I returned home last week, I set about first just looking at the differences between the files once my import presets for each camera were applied. Then started the process of matching the files. I only used the global tools in Lightroom. No Photoshop. No adjustment brushes. Just slider adjustments. This proved to be most enlightening; I was able to pinpoint the changes necessary to achieve very similar results from the M 240 relatively quickly. To be clear, I didn't necessarily work the M 240 files to make them look the absolute best they could be. Rather, I took the challenge to match them to the finished M9 images to see if there was a definitive “CCD Look” that could or could not be replicated using a CMOS based camera. I also selected shooting scenarios that favored the M9, namely good directional, natural light, at lower ISO settings. This wasn't intended to be a competition between cameras, per se, but instead one to test the theory of inherent sensor color.

The next step is to now open this comparison up to the world at large and see if, despite my Lightroom processing, the “CCD Look” is still clearly identifiable when looking at these sets of images. So, I'm asking you, my intrepid readers, to take the challenge and see if you can correctly identify which images are from the M9. Don't vote for the one you think looks the best, just the one that you think is from the CCD sensor. Take a close look at each set of images. Click on them to enlarge (but do be aware that if you roll your mouse cursor over the images, we have a darkening rollover effect on our website – make sure your mouse is not over either image when viewing for comparison). Open two windows side-by-side. Do whatever you need to do. I've stripped away the metadata and changed the file names to protect the innocent, so no peeking. Once you vote on each set of images, you'll be able to see how others voted, but not image data. For that, I will publish a follow-up once we collect a statistically significant amount of votes, revealing the camera data and presenting my analysis. I know that there is a fairly large number of images (19 comparisons). Please do your best to select the M9 image from all the sets as this will help give us more accurate results.

Also, be sure to check out Part 2 of this article where I challenge you to select which camera took which image, without a direct comparison.

Now, let the voting begin!
