    Source is on fire today, apparently new firmware 4.0 for X-T3 is around the corner:

    Attila Bakos reacted to Juan Melara in P6K to ARRI Alexa - Resolve PowerGrade   
    Yeah you're correct, but I already had a library of those charts from various sensors and stocks, so it made sense to keep adding to it. Plus it's also actually quite helpful to have so many samples within the colour space, rather than just a few samples right at the edges.
    Thanks mate! Much appreciated.
     
    Another interesting thing I found in testing is how much dynamic range the P6K actually has. According to the charts published by BMD and ARRI, when both cameras are exposed at ISO800, the Alexa has 1 stop extra range in the highlights, but approximately the same amount of stops in the shadows. In testing I found this to be pretty much spot on. I found I could expose one of the charts exactly one stop higher on the Alexa before it touched the clip point.
    The interesting thing is how that actually translates in real world scenarios, and what that difference looks like.
    Here are some crops of a scene shot on both cameras. In LogC, so the differences are visible. I matched exposure on the day using false colour, they're as close as I could get them. Probably less than 1/20th of a stop of difference in exposure.

    The left image is the P6K. When comparing it to the Alexa image in the middle, thats exactly what 1 stop difference in the highlights looks like in a real world situation.
    It's interesting to see what happens to that 1 stop difference when highlight recovery is enabled – the P6K actually retains more highlight detail.
    Obviously you would never actually place important image information in that range (not that you would ever do that with the Alexa either). But if you need it create a smoother roll-off in anything neutral in colour like specular highlights, clouds etc, it is possible to outperform the Alexa in highlight dynamic range... sometimes.

    Try exiftool. I believe that there's a FilmMode tag that has the info you need.

    Since 16.1 it's possible in the studio version. It's under Workspace -> Video Clean Feed.

    I purchased the N-Log IDT and it is perfect. Everyone should be grading N-Log using this method.

    I swapped XH1 for XT3 for video in order to get:
    60p 4K 10bit eternal.
    The sacrifice was the superior build and handling of the XH1 and of course IBIS.
    Just give me the spec of the XT3 with IBIS in the XT4 and my spec quest ends for at least the next 3 years.

    Changing gamma and color space with the right-click menu on the node only works if your timeline gamma and colorspace is set according to the clip you're viewing.
    So if you're viewing an F-Log clip, and you're timeline is set to Fujifilm F-Log, you can right click the node, set gamma to linear and adjust exposure with the curves the way I described before. It will be like a node between two colorspace transform nodes, but compressed to one node. But what do you do when you have clips from multiple cameras? I like the color space transform plugin better because I can see better what's happening. And sometimes you want to see what's happening between the transformations, in our case the linearized image. When you use the one-node method you don't get to see that, you only see the output of that node.

    To anyone wondering about exposure controllers in Resolve:
    You can use the offset wheel in ACES, it's very close to a true exposure controller, but only in ACES.
    In normal Davinci YRGB mode you can linearize the clip using the Color Space Transform plugin, and once in linear mode you just grab the top right part of the curves and grab it along the top or right border. Because you're in linear mode this will be simple multiplication, so it's an easy way to control exposure. Then you use the same plugin to convert back to log.

    That's a fact, Panasonic did not release an IDT, they say the GH5 is not compatible with ACES. Bullshit.

    Attila does great work, he has an excellent grasp of the technical; highly recommended
    That 4K 60 sounds quite good (super-sampled 10 bit)
    Ironically, I've still been working away at the EC engine, and fixing copious bugs (its inevitable that when I think a thing is finished, the work has just begun ) That being said, I think today I've fully tested it, and everything is working really, really well.
    This is a GHa Tungsten LogC render from this morning; the wheels on the far left and right are completely theoretical extreme gamut, beyond what the camera can record - the ones in the center are actual log gamut (and V3 for comparison):
