  1. Hi,

    I think it would be helpful to have CA and distortion correction is CB.

    The difficulty in both is of course that these 'faults' aren't in the same degree across the frame.

    It would also be nice to make the degree of control wide enough so that we, instead of removing it, can also add these distortions (eg. to fake a fisheye lens).

  2. For a lot of photo (and video) professionals a colour chart - like the Macbeth one (see image) - is an important tool to give the best possible colour representation in our pictures.

    The the way CB handles batchprocessing is perfect to use this kind of tool. We could just move an overlay over the chart in the picture (similar to how Davinci Resolve handles it) and the software should do the rest, add some other changes (the fact that we can move between images while keeping the same 'filter' makes this super easy) and we've lost no time going through countless software packages generating DNG's, camera profiles, exporting all images before being able to edit them (loosing quality, definitely when using JPEG's) etc.

    With kind regards,

  3. (If Camerabag already has GPU acceleration it should be noted somewhere on the site since I couldn't find any information on it. However it doen't seem to be the case.)

    This is not the highest priority since it requires a ton of additional code and since Apple doesn't seem to want to support Vulkan the macOS version would have to run on Metal...

    However having GPU acceleration is a basic requirement nowadays and would make everything a ton faster which is definitely interesting when doing batchprocessing.

  4. Hi,

    Is there any chance of Camerabag Photo coming to Linux any time in the future?
    Linux misses a decent (not overpriced) easy to use photo suite and I think Camerabag would be able to fill this void.


  5. I'm using a mouse on Windows, I could lower the sensitivity or increase the mouse acceleration (to get the effect you describe) but those would make everything else harder. So having the option to switch between the sliders, colour wheels etc. moving one to one with the cursor to 1 millimeter for every four of the mouse (or something similar) while pressing a button (eg. Alt) would give us that extra level of precision.

    While pressing this button the rate of movement by scrolling (which is a very useful option while working with curves to only change the control point in one axis) could also be lowered so you you can make precise changes this way.

  6. Hi,

    If I'm correct the chrominance chart is basically an unwrapped version of the vectorscope? The dark grey lines show the max saturation of the colourspace and the lighter lines of a normal TV. So the colour targets in a traditional vectorscope are then just the angles in the light grey line. So the only thing that isn't yet there are the I, -I, Q and -Q lines Doug already showed, however the only thing really necessary is the I line (the one between yellow and red) which, if I understand the chart correctly, would just be a vertical line.


  7. Hey,

    I was looking at the chrominance chart and I still think that a more traditional vectorscope is easier to use (but that can just be me, failing to understand the chart). However something a lot more important is the skin-tone line which seems to be missing.

    Whenever you try to colour correct a picture (or video) the most important thing is to get the skin-tone's right.

    Another important thing on a vectorscope are the colour targets (these are especially important when using something like a Macbeth chart).

  8. Hi,

    I was wondering, since CB Cinema supports it, if it is possible to bring LUTs to CB2 too? And apart from that, the only thing missing for me are different colorspaces and especially Lab.

    Thank you for making this awesome piece of software!
