    لطفي بوعكاز got a reaction from tokhee in Samsung NX1 Film Convert is out!   
    after week long extensive tests, I finally come to conclusion that I'd use Gamma DR standard with -15 sharpness and MB15 for a uniform and flat skintone look, this look is good when the actor has no makeup but for more gritty look I use gamma C which gives more color depth especially on cheeks are more red than the rest of the face however I recommend makeup to smooth the face "BB CREAM" works nicely.
    I didn't like -4 sat and -3 contrast nor -4 contrast and 0 sat because no matter what you do you can't return the pure black back on, if you adjust black level or contrast it affects the entire image, that's why GammaC is very good for darker tones, like horror, thriller, mystery but Gamma DR is good for comedy, romance. 
    For nature, outdoor, buildings I prefer Gamma C, this is because it has much less macroblocking in the blue channels "sky basically" unless your sky is cloudy maybe you want Gamma DR. 
    with Gamma C you want to expose to 0 this is because its blacks are darker, for Gamma DR I underexpose to -3. 
    remember we are using 8bit color, professionals use 16bit color for flat profile because they have the headroom to do the grading, our cameras have to be adjusted as close as possible to your final look otherwise it will start breaking up especially walls, skys and flat surfaces where repetition of pixels occur. 
    I also ordered a lens filter glass "Tiffen Black Satin 1" this is so I can smooth out the face's blemishes, because the camera is too sharp in order to reduce macroblockings which occur when there is too much details in sky, flat surfaces ect..you cant fix this in post it has to be fixed before the image hits the censor. 
    Also thanks to this forum for my research, I tried all your settings, without them I wouldn't have come to my personal conclusion

    لطفي بوعكاز got a reaction from vaga in Petition for Samsung NX1 hack   
    I spent the entire day testing 0-255 vs 16-235 vs 16-255 and thanks to the tip for "brightness -3 and contrast -15" that I can for sure use 0-255 in premiere cc 2015 and wont have any clipping, while maintaining the full color for exporting in DNXHD and also maintain the Legal color for Youtube and Vimeo. 
    when I used 16-235 I did a test while reducing exposure and it looked very nasty in premiere with banding everywhere, looked very clean in 0-255.
    with 0-255 you can recover superwhites, like clouds for example, the detail in shadows is much more and the blocking, artifacts is not there "when using bitrate hack"
    when using 16-255, this was better than 16-235 but still not as good as 0-255. 
    I did notice that VLC plays the 0-255 while all other players didn't read the superwhites in 0-255 so that could be an issue. 
    so my advice is use 0-255 with -3 brightness and -15 contrast but export 2 versions, one Legal for web players and TV and keep the original for the future.
