    Before you pay anyone for a LUT,

    LUT Buddy and Colorista are free from Red Giant:

    http://www.redgiantsoftware.com/down...free-products/

    The free Technicolor LUT is here:

    http://www.technicolor.com/en/hi/cin...tyle-downloads

    Load it up in LUT Buddy, and like magic you have a really nice place to start grading your footage with Colorista.

    It works really well.

    Cheers,

    Visugeek

    - upload them to the camera with EOS Utility, in P mode
    - disconnect USB cable
    - turn dial to Movie mode
    - press MENU button, go to 4th tab with Left/Right buttons, enter Picture Styles
    - scroll down to User Def 1., press DISP. button
    - press SET on the first menu item (Picture Stlye)
    - with Up/Down buttons select your custom style (Flat, Marvel etc)
    - press SET again, then MENU to go back
    - do the same for User Def 2 and 3.
    - exit by pressing MENU several times

    After this, when in Movie mode, press Q button, with Up/Down buttons select the picture styles icon, and with the dial scroll to your desired custom style. Its name will be displayed on the bottom right of the screen.

    Red Giant Magic Bullet LUT Buddy; being free, I don't think you can complain at the price (yet, as someone else said, it doesn't work on avid)

    BUT YOU DON'T EVEN NEED IT: I opened the .lut file on a text editor, and it's just three S curves, for RGB, and they're all the same! So I got the Technicolor Cinestyle ultra flat image, applied some curves to it, and got basically the same result as with the LUT! This means that this ultra flat picture style is so nice that you can get back your pretty colors with a simple luma S curve. COMPLETELY DIFFERENT FROM MY EXPERIENCE WITH PREVIOUS ULTRA FLAT PICTURE STYLES. Amazing.

    take a look at these two histograms:

    picture taken with Neutral picture style and contrast=-2:
    crop_neutral1_2_h.gif
    same picture, taken with Technicolor and contrast=-4, then LUT applied:
    crop_technicolor3_lut_h.gif
    the first one represents "trying to get in camera something close to your final image", the second one is "shoot with the Technicolor picture style and then get your final image as you want it in post"

    as you see, if you don't need the DR, it's best not to stretch your color space too thin; apart from making the codec closer to 7-bit (128 shades instead of 256) at the time of capturing your images, with the LUT you're adding contrast to all the noise and sharpening artifacts in your recorded images
    here you can see the original pictures and further explanations:

    on the other hand, as Evangelos said on this other thread, having a log color space is nice:

    In “linear” the top brightest stop n. 8 will consume 128 steps, the stop n. 7 will consume the next 64 steps and the stop n. 6 will consume the next 32 steps. The top 3 brightest stops of an image when is being described in linear will result to “consume” the 87,5% of the available bits in a file, leaving the lower 5 stops of the mid-tones/shadows to be described by just 32 bits…!!!

    On "Log" we allocate 10 stops in equivalent segments like 25 bits for each stop. That results to a secondary data compression of an applied curve, which needs to be decompressed with the use of an appropriate 3D LUT in order to counteract accurately also the saturation of the converted image. By doing that we effectively recreate information that wasn’t visible in the original file but was there in the original image the sensor was capturing.

    So the difference between Linear and Log is night and day… given that you use the correct conversion 3D LUT.

    Oh yeah Buddy boy, free is the right word. I did stumble across that after a little surfing, thanks.

    It doesnt really add any more dynamic range than neutral and -4 contrast, but it doesnt make specular clay-like faces when you bump contrast in color correction ,adding contrast will reduce dynamic range tho and blow out whites quickly so i dont know... its harder to judge white balance with this technicolor profile.So you record flat picture and bring back contrast and end up with picture like with regular picture styles,is it worth it i dont know really,blacks are bumped up ,there is no black actually and you need to crush blacks adding contrast to get details on faces.

    it records a lot more DR than neutral with contrast=-4, then crushes it in post with the LUT/Scurve, that brings it close to what you would get in camera if you shot neutral with contrast=-2; but it's a non-destructive crush: it doesn't destroy your shadow detail (it is still there, under your S curve or LUT, and you can recover it if you want)
