brianv Posted September 6, 2012 Share #41 Posted September 6, 2012 Advertisement (gone after registration) What about TIFFs? I believe we had our last prints printed from uploaded TIFFs at Whitewall. TIFF is a "wrapper" that can handle many different formats, has many options. Usually it is used to store uncompressed images. I did some experimenting with the monochrome images from my old camera. I cannot upload a ".BMP", but converted the enlarged image to JPEG using the highest setting (12) and a lower setting (10). Highest setting is essentially lossless, at least to the last bit. The "10" setting is a 4:1 compression. You can see the artifacts creeping in on the compress image, but the "max" image looks fairly good. The "BMP" file, biggest different is the sky is a more uniform shade of grey. Please remember this camera is 20 years old. Things have improved, this camera has 8-bit depth. I'm looking forward to the M Monochrom with it's 14-bit depth. Waited long enough for one! Welcome, dear visitor!

Advertisement Posted September 6, 2012 Posted September 6, 2012 Hi brianv, Take a look here Monochrom - Image Samples and Thoughts. I'm sure you'll find what you were looking for!
brianv Posted September 6, 2012 Share #42 Posted September 6, 2012 Just to reiterate: if you are going to use JPEG with the Monochrome, be sure to save at the highest quality setting. Everything else will introduce some ugly artifacts. When I get the new camera, will try some JPEG 2000 tests. Link to post Share on other sites More sharing options...
johnbuckley Posted September 6, 2012 Share #43 Posted September 6, 2012 If I had any doubt about how much fun I would have with the Monochrom, walking in my garden for two minutes with it this afternoon confirms the rightness of the purchase. Monochrom, ISO 320, Noctilux at f/0.95, no filter, thirty seconds in Lightroom 4 to crop out the portion of the image that had blown highlights, a little contrast added. Welcome, dear visitor!

adan Posted September 6, 2012 Share #44 Posted September 6, 2012 Here's a threshold check of the original MM lightpole image. Threshold level 138. The sky in most regions is brightness 140-143, but there is definitely a dark "cloud" around the light and pole, (also the building) that extends out a long way, where the brightness drops off to as low as 120 while still clearly "sky" and not "structure". There are some jpeg artifacts - "racing stripes" along the wires, the bright halo edge to the light and pole, and checkerboarding near the lamp - but this cloud sure looks like something different. Way bigger than simple "neighboring pixel" interpolation issues. Could be a camera artifact, could be some kind of lens diffusion, could be something else. But it sure exists....

Did you start with the original DNG file for this image? Starting with the original DNG: bring up as a pseudo-color image to essentially get a contour map.

Jose_Salcedo Posted September 6, 2012 Share #46 Posted September 6, 2012 The Monochrom will be manufactured in limited quantities due to the custom sensor. Jose When I look at the screen close-up, the grey of the sky is uniform and meets the street light, no dark line. At a distance, sometimes the transition looks darker. I also believe it is an optical illusion (artifact of vision) and not the image itself. Spatial Gradients. As for availability- Leica is very good at announcing limited production cameras, and letting everyone know how many will be produced. No such announcement with the M Monochrom, every indication that this camera will be manufactured until everyone that wants to buy one will have one.

brianv Posted September 6, 2012 Share #47 Posted September 6, 2012 Advertisement (gone after registration) Kodak, and now Truesense, has manufactured monochrome sensors for a very long time. Others beside that KAF-18500 are in current production. The company is still in business, manufactures detectors, and will make as many as Leica wants to buy. The latter is more the production limit, and I suspect Leica will make as many M Monochrom's as customers want to buy. Link to post Share on other sites More sharing options...

brianv Posted September 7, 2012 Share #52 Posted September 7, 2012 If people are downloading JPEG's off the internet, you have no idea of how the image was processed. I've been looking at Jono Slack's DNG files, and see nothing like the artifacts shown in the JPEGs. I've been looking at monochrome files from my ancient camera, basically the great-great-great-great grandfather of the M Monochrom. No artifacts in images UNTIL conversion to JPEG. So- try the camera, or at least download some DNG's to try some processing. For myself, money down on the camera before holding it or downloading a DNG file. Just waiting for it to come in! F3 by anachronist1, on Flickr Mods- the monochrome images from the KODAK monochrome are for discussion purposes only. When my M Monochrom comes in, I will repeat the test. Until then, this is the only monochrome digital that I have access to. Historical note: it is the very first commercial digital IR camera sold. Kodak did a production run of 50 detectors with the IR cover glass left off. Link to post Share on other sites More sharing options...
johnbuckley Posted September 7, 2012 Share #53 Posted September 7, 2012 Can you please post the full original dng? Yes, happy to. Would you mind sending me a PM or just posting the best way to do that -- not sure how to do it via the Forum, and I don't have a Dropbox account. If I emailed it to you, could you post it?

johnbuckley Posted September 7, 2012 Share #54 Posted September 7, 2012 If you can tell me how to publish the DNGs so people can play with them, this one might also be good to play with as it is an example of the tonal range of these files. Now, this has been worked over a bit in Silver EfExPro2, but it's the same deal as the above picture, albeit taken at Washington's National Cathedral: ISO 320, Noctilux wide open.

Monochrom, ISO 320, Noctilux at f/0.95, no filter, thirty seconds in Lightroom 4 to crop out the portion of the image that had blown highlights, a little contrast added. congratulations John. I would like to quote Thorsten Overgaard: The simplicity of the Leica M Monochrom: It's fun!For me (and for you?) it is "back to the roots". I would like to show you a picture from yesterday from the Leica M Monochrom with Zeiss C-Biogon 21mm/4.5@f/8 and orange filter 22 the result is a matter of taste and you may do it different. But this is, what I saw, taking the shot. click for magnifications here is a screen shot from LR 4.1, the exposure is very dark to take care of the clouds. In the field you don't see anything on the screen of the camera besides the histogram! and the screen shot from Nik Silver Efex2 my impression is, that the noise is increased from Nik. May be, I have to do more testing. Link to post Share on other sites More sharing options...

drdannn Posted September 7, 2012 Share #60 Posted September 7, 2012 I have a question: Does the M Monochrom offer any more IQ than an M9 processed with Silver Efex? I know there has been hundreds questions and ideas in multiple threads about this camera. So I'm wondering if there's anything the MM camera can do that my M9 can't do when processed in PP? Thanks. BTW I love BW photography. Link to post Share on other sites More sharing options...
