TheBogart Posted September 24, 2012 Share #1 Posted September 24, 2012 Advertisement (gone after registration) Just by using this experimental software. You turn the color DNG in Monochrome DNG, retaining the sharpness! This still a beta, but i think it will be even better in the future. Here´s the Link http://www.mymymyohmy.com/software/dngmonochrome.html I found this on the web in a search for proper convertion to B&W. All props to the author!

IWC Doppel Posted September 25, 2012 Share #4 Posted September 25, 2012 Interesting, I note he did say he might develop a MAC version if there is enough interest Link to post Share on other sites More sharing options...
Paul Verrips Posted September 25, 2012 Share #5 Posted September 25, 2012 I vote for a MAC version! Link to post Share on other sites More sharing options...
adan Posted September 26, 2012 Share #6 Posted September 26, 2012 Not that easy, I'm afraid. So long as there is a Bayer filter in the camera, an M9 will record the world differently than an MM. Simply removing the interpolation won't change that fact. Example: shoot a picture of someone in a blue shirt. The MM's pixels will all respond to the blue identically. The M9s pixels will respond in a checkerboard pattern - the pixels filtered blue (25%) will see a nearly white shirt, the green pixels (50%) will see a medium gray shirt, the red pixels (25%) will see a nearly black shirt. Either - you still have to average the grays from neighboring pixels to get rid of the checkerboard (which is - interpolation!) Or you don't average the grays from neighboring pixels - and you get weird artifacts on colored objects. The site linked to admits as such: "DNGMonochrome uses quite a bit of memory when constructing the red and blue filtered image... memory usage can go up to 300 or 400mb. This is normal, since in the red or blue process, DNGMonochrome is juggling several copies of the original DNG and needs additional memory for the processing..." i.e. it has to interpolate ("construct," "processing") the M9 pixels to get even grays. and "On high ISO images (especially M8 DNGs - but possibly also compressed M9 DNGs), the two sharpest algorithms might produce white speckles. Turning on the median filter - or using the 'smooth' algorithm - solves this problem." i.e. - you get residual artifacts ("speckles") - unless you use a blurring filter (median or smooth). What this software is doing is pre-interpolating the image (possibly by a better method than regular raw processors, but it is still interpolation, with the accompanying averaging (fuzzing together) of neighboring pixels) and then wrapping the result in a "monochrom.dng" wrapper so it doesn't get re-interpolated by Lightroom or whatever. I'm no Monochrom fan-boy - I shoot too much color to want a dedicated B&W camera. But at least I understand what it does that simply cannot be replicated by applying any software after the fact to M8/M9 files. That's toothpaste that can't be put back in the tube.

250swb Posted September 26, 2012 Share #7 Posted September 26, 2012 Advertisement (gone after registration) Or you could look on the bright side. If the MM responds to every colour in the same way, the M9 can use its colour information to make a better B&W image by the traditional use of colour filters and interpolation. I've yet to see an MM photograph that looks different from the next, perhaps the higher ambition should be to find the best digital way to make a B&W image using the old tools and methods with the photographer and not the camera deciding on the placement and value of tones?

iedei Posted September 26, 2012 Share #8 Posted September 26, 2012 great program..but needs a Mac OSX version before i'd try it. I'm not about to install Winblows on my Macs Link to post Share on other sites More sharing options...
Ecar Posted September 30, 2012 Share #9 Posted September 30, 2012 Just had a quick go at it - without playing too much with the options available. Output is rather clean and "neutral". Will have to do some comparisons with PS, LR and SilverEfex when I have time. IMO it's just another raw processing and conversion tool (which is good) but it won't be a substitute for extra resolution or high-ISO capabilities...

Yep, this is another raw processor, but has the ability to do a Good convertion to B&W. Lets see what the future brings. I Like The output of this software.
