  • Reading rgb values and few more newbie questions

    Posted by Mario Moskon sarunic on March 8, 2011 at 10:35 pm

    I’m using Resolve for a few weeks now and I must admit I’m falling in love but I need some tips from more experienced users.
    Is it possible to use some kind of eyedropper in Resolve to sample color? Not color picker to qualify but just to read rgb values of pixels? Sometimes, especially when you work a lot its really hard to judge by the eye if that white is really white or black is really black so I’m looking for a way to double check my sight and speed up work. Before I started to work on Resolve I’ve played little bit with Color and I’m really missing some features like those 3 pickers/markers you can use in 3d color space. I loved feature in Color where you could zoom to segment of your picture in Geometry tab and read on your histograms only informations from that part of picture. Is there a way to do that in Resolve?
    Also I’m missing shadow/mid/highlight wheels from Color, I found them much easier to read than Resolve rgb sliders but I guess I’ll overcome that with experience.

    No color wheels here. I guess that’s why it’s a big plus to have a panel with a ring and ball x 3! 🙂
    I tend to use the curves a whole lot, but some times, if I need better precision, I use the RGB controls. Click and drag. One at a time.. You know the drill!

    Do you use scopes, either externally or in Resolve? If you don’t know – right click on the video image (in the Color page). From the menu that pops up, you have a few choices on what kind of waveforms or scopes you want to see.

    Some broadcast monitors have a cross hair which you can position over screen areas with rgb feedback, not what you’re after I know, but I solution if your monitor has this option…

    Ola I have Tangent Wave and that is fine, it would be really hard to use Resolve with mouse only. Those color wheels are quite helpful afterwards because you instantly see what did you do with your picture, by just looking at them you can quickly see that you moved your blacks to blue, highs to yellow etc.
    I use scopes from Resolve and that cross hair Jay is talking about would be great but I don’t have it on my reference Jvc monitor. Is it possible that there is no way of sampling color and reading rgb values within Resolve? For example, how do you verify that your highlight is really white?

    Whites being really white: That’ll be with scopes, ensuring your highlights match from left to right on the scopes, overlay mode is okay too, but not quite as accurate in my experience… if you’re getting eye strain and want to see it visually, a quick way of getting some visual feedback is switching your monitor from b/w to colour and seeing where the where the white hue lies (this applies to blacks too, although mid-blacks in the real world are very rarely true black, but this will depend on the prevailing lighting within a scene, but at least you’ll know if they are too blue, too yellow, green etc), this does assume you can trust your monitor…

    But accurate scopes really are your best friend when grading..

    OK, to answer myself friend of mine gave me tip today so eyedropper issue is “solved” 🙂
    I’m using DigitalColor Meter that is coming with OSX :))
    Far from ideal but it’s working for those rare occasions when I really need it.
