I am not used to Windows but I have a copy of Windows 10 running in Parallels Desktop. In the prompt I wrote C:\Users\admin\Desktop\m9tofilm\m9tofilm.exe -i "C:\Users\admin\Desktop\input" -o "C:\Users\admin\Desktop\output" -f trix400 -gamma 2.2 but nothing happens.

alex7075 Posted February 24, 2020 Share #87 Posted February 24, 2020 Advertisement (gone after registration) Well, this is the best method to match analog images I have ever seen. I am really impressed. Particularly, you get the typical film rendering of zones 6 to 9 (in Adam's zone system's terms), so hard to obtain with usual software. The grain option is also better than any other method I tried. I am still testing it on different light conditions, but as far as I can see, sunlight, open shadow and against the light images are really good. One has to move the midpoint of the levels settings, apply some sharpness and of course local dodging and burning. I'll try to post a couple of examples the next days. Congratulations Tomás and thanks for sharing this software. 1 Quote Link to post Share on other sites More sharing options...

Congratulations Tomás and thanks for sharing this software. Hi, thank you very much for your words :-) It really encourages me to keep working on this project :-) I think sharpening is needed because of the debayering algorithm used by LibRaw. I'll add a command line option to choose the debayering algorithm. Also, I must say, I would like to do this for the Leica M10, but, unlucky, I don't own it and it's kind of hard to rent one here in Spain to do the calibration process. (and, of course, at the price it pays, I'm not willing to buy one at the moment) What I have notice is that the film has looots more of resistance to burn highlights, meanwhile on digital it gets burn quite fast. Oposite for low lights. An option I was thinking was to shoot always at -1 stop (or even -2) and then do the push with the software. This would add two stops of extra resistance to highlights and the noise in the low lights should be more or less imperceptible. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! Here is a graph showing the tests I did about one year ago, film has a little more dynamic range, but it's more tolerant to highlights. I think with a little bit of work and some resources it's possible to mimic the film simulation with digital cameras. Not doing it so "generic" (I mean, for all cameras, only for specific calibrated ones) and using a more "scientific" method of simulation that just adjusting curves or doing color transformations. As said at the beginning, in the end, a digital camera and a film camera, they capture the spectrum, so, does it exist a transformation from one to the other assuming the digital has more info than film? Kind regards and, again, waiting to see your resulting images!! Tomás Quote Link to post Share on other sites Simply register for free here – We are always happy to welcome new members!

With the M9 Monochrom I always shoot at -2/3 to avoid highlights burning. Question: can I use M9TOFILM also on M8 dngs? Quote Link to post Share on other sites More sharing options...

Question: can I use M9TOFILM also on M8 dngs? I've been doing some tests with the LeicaM8.2 and it works perfectly for HP5 ISO400. When I started doing this I was using HP5 because it was cheaper than TriX 400 😅 Will try to update the app this weekend and upload it to Megaupload. Will let you know. Welcome, dear visitor!

camalogica Posted March 8, 2020 Author Share #92 Posted March 8, 2020 Hi everybody, I've added the M8 to the program with the calibration I already did in the past for HP5 film It's possible to download it at: https://mega.nz/#!tJsEzSbC!g6NNJur6fZLB-kaR36KTPZEcBlLOk3Kv2TH3bM-kg00 To use M8 DNGs it's mandatory to add the "-m8" option at command line. One example would be: m9tofilm.exe -m8 -i "E:\DATA\LeicaM8.2\dng\HP5" -o "F:\DEV\output" -f hp5400 -frame That would transform all DNGs contained in the input folder, to the output folder, for film HP5 and adding frame to them. Kind regards and I hope you like it 🙂 Tomás 1 Quote Link to post Share on other sites More sharing options...
alex7075 Posted March 10, 2020 Share #93 Posted March 10, 2020 Tomás, Can the -m8 option be used with trix400 option or just with the hp5400? As far as I understand, it can be used only with hp5400.

convexferret Posted March 10, 2020 Share #95 Posted March 10, 2020 Tomás. What does the calibration require? I have an M10 and would be happy to run some experiments for you if you can give me a spec. Quote Link to post Share on other sites More sharing options...

Hi, basically doing a bunch of photos to many calibrated self-made templates I've done under certain conditions. That way I can have the exact light spectrum's response per pixel for the camera. I would like to calibrate the M10 too, but unluckly i'm not willing to spend 7000€ aprox, and no way that I know to rent one during one weekend. I think it's kind of hard unless we meet in person Southern Spain is where? I'm based in Valencia. Tomás Quote Link to post Share on other sites More sharing options...

I was using raw2dng with M8 made by Arvid (https://www.l-camera-forum.com/topic/216705-m8raw2dng-tool-to-convert-leica-m8-raw-files-to-dng/) so it's normal it doesn't recognise standard M8 DNGs. Will fix it in a couple of hours and repost the new corrected version. Sorry for the mistake! Tomás Quote Link to post Share on other sites More sharing options...
camalogica Posted March 10, 2020 Author Share #100 Posted March 10, 2020 Hi again. I've corrected the bug and uploaded the new version to: https://mega.nz/#!gRklDZRR!gvfpt3MgT7KCmfhpmY7GPsQ7mUZQky8onOPfuElGFZE Just remember that, even if it works with M8 + HP5 this was done at the very begining of the developing process, so, I think M9 should be better to test. BTW: Even if M8 has a little bit more DR, there is almost no difference between M8 and M9 (the eternal discussion). Only that M8 is a little bit more tolerant to highlights (about 1/4 stop).
