    Hi guys I'm back with one last realization and we'll call it a solved! So I was thinking for a few years, until I found out about (mono!) 32bit floating point tiffs files which solves the final issue of the blacker then black you get with the original dng raw. Here's a quote from https://en.wikipedia.org/wiki/TIFF - "The inclusion of the SampleFormat tag in TIFF 6.0 allows TIFF files to handle advanced pixel data types, including integer images with more than 8 bits per channel and floating point images. This tag made TIFF 6.0 a viable format for scientific image processing where extended precision is required" And this one - http://scikit-image.org/docs/dev/user_guide/data_types.html Data type Range uint8 0 to 255 uint16 0 to 65535 uint32 0 to 232 float -1 to 1 or 0 to 1 int8 -128 to 127 int16 -32768 to 32767 int32 -231 to 231 - 1 only downside is a 4gb max file size but should be an issue plus they are working on bigtiff format to solve that Anyways, logic's wins I rest my case.. Its not recommended to actually use it of course except maybe for HDR maybe but still happy i got it finally. i hope everyone agrees, if anyone has in new interesting insight it would be great. Have a great weekend :) Keep on shooting mono

    yap, i tend to agree.. as long as we're not sure, we should use raw, and also we don't have an in-camera choice anyways so all of this doesn't really matters in the practical sense.. my logic still wont let go though, the theory is not complete. all of this reminds me of brain research - where they know lots of stuff, but they lack the true understanding, the logic behind the results, the theory.. everything they know is a result of trail and error. i prefer true deep understanding.. it was a great thread everyone, my first of this magnitude

    didn't got it but as long as you're happy, i'm happy.. baa
  4. koferk
    bummer.. well at least i tried, as hard as i could
  5. koferk
    its important to mention this is only a logical question for me, im just trying to understand and not to "do" anything, at least not at the moment. secondly, the Nikon D800 for example can shoot TIFF Nikon D800 D-SLR Camera | High Dynamic Range Camera now for our main subject, you wrote "These are operations that are impossible/very hard or time-consuming to do in post processing, so are far better handled in raw conversion and firmware." and so my question is, which specific one is impossible, and more importantly, why is it impossible in your opinion ? meaning, as to get the same results, time and computing power is irrelevant for my question.

    don't you think 8g should be enough ?

    very interesting! thanks for keep on going here so i read the quote, lets go over those eight essential steps for a moment for a check up - 1. decoding - for compression which is just a matter of file size. (nikon and canon seems to do some kind obfuscation but that's surly not essential if only some camera makers do it) 2. defective pixel removal - my favorite and the best thing i've learned so far, but then again, assuming your camera is fine, it wouldn't matter. 3. white balancing - as someone here mentioned and i've learned, there's no white balance for monochrome. 4. demosaicing - on this we all agree, no filter for us i will continue till number 8, even though everything after demosaicing is either demosaicing related, or color related. 5. noise reduction - mosaic filter related. (please correct me im not sure how this actually works, i can only imagine its related) 6. color translation - no color for us. 7. tone reproduction - a color thing ? filter stuff ? not sure. 8. compression - jpeg stuff. after number 8 they write it clear: "Note that demosaicing is only performed for CFA sensors; it is not required for 3CCD or Foveon X3 sensors.{..and non-Bayer-filtered sensors}" so it seems after the demosaicing its all related to it in this way or another. to sum it up - im still high above please feel free to keep correct me, i've learned a lot so far, thanks!!

    that is simply not true. many of nikon's dslr's can shoot tif format, in camera. but it also unrelated. can someone tell me what are the 14 steps the raw converter does ? thanks.
  9. koferk
    Im sorry for my style.. my english isn't the best.. could you please say what are those 14 steps ? thanks. I agree that "Black point is defined in raw by the camera firmware but can be shifted in raw conversion and postprocessing." that still doesn't make no black blacker then any other black.. they are all blacks.. and also, the fact that something can be done in raw, doesn't mean its raw only.. a simple example can be crop. do it in raw, do it in tif, it wont matter. i have the feeling that all i read here is explanations regarding regular raw and no explanations for the "special" (simple!) monochrom raw.

    "eight to fourteen steps" - where do you guys bring this stuff from? is it 8 or 14 ? or maybe 12 ? but more important - what are they??? there is no such thing as blacker then black, the same way there is no such thing as "more" yellow then yellow or more cheese then cheese. all there is to it is a photosite, and a pixel, which have the same data value. one represent that data in raw form and the other in bitmap form (tif for example). the way i see it, theres nothing more to it. its the same data packed in a different form. that's all. (i guess i still don't get it)
  11. koferk
    interesting article- Color vs. Monochrome Sensors "Unlike with color, monochrome sensors also do not require demosaicing to create the final image— the values recorded at each photosite effectively just become the values at each pixel." - exactly what i meant.. One should also consider whether the quality of a monochrome sensor outweighs the flexibility of a color sensor. - no "raw" flexibility in monochrome, its the same as not having raw but only having a tif.. the first quote is the more suited, its just says exactly what i mean.

    word..

    i will try that other forum (as well) thanks.. a few answers - first of all, i did actually edited some tif's with audacity in order to do some glitch art - i recommend it to everyone, it's lots of fun. http://www.fileden.com/files/2012/10/19/3358811/glitch-art-audacity.jpg now try to do that with photoshop and see if you can come close besides that - all digital things are always nothing but zeros and ones, not only raw files. and also, every file needs a software and a computer in order to "be something" more then zeros and ones. so again, i know this "explanation", but all you say are old spins i already know. its like even if the leica-mono could shoot in tif, everyone here knows that mono-raw is the best way to start editing, but no one really understands why. i guess we all agree here (sort of) - its just that no one seems to be able to explain. much love to everyone if you have more ideas of how to explain this to me, please do

    the audio file is related in that they are both the same kind of data files. raw sensor data.
  15. koferk
    please don't be mad at me. just read Raw image format - Wikipedia, the free encyclopedia here's the quotes: "To obtain an image from a raw file, this mosaic of data must be converted into standard RGB form. This is often referred to as "raw development". -we don't need to do it of course, no RGB for us "Other sensors, such as the Foveon X3 sensor, capture information directly in RGB form (using three pixel sensors in each location). These RGB raw data still need to be processed to make an image file, because the raw RGB values correspond to the responses of the sensors, not to a standard color space like sRGB. These data do not need to be demosaiced, however." -Color space is also not an issue with monochrome. its just grey-scale with NO color or RGB of any kind. this might help as well - TIFF/EP - Wikipedia, the free encyclopedia anyways, you guy didn't convince me on this one i might try another forum
