    FSI Dm240 password lock

    Hi all, I might have to lend my monitor to another colourist. Do you know if is there a way to password/pin lock it so no changes can be made at all? I have looked through out the manual and checked other forum but I haven't found the answer i need Cheers, Orash
  2. Hi all! in the colour lounge facebook group a pretty interesting topic was recently diccessed. Something that cought my eye was this post from Walter Volpatto. I'm not sure if he's part of this forum, here it is: Of course I could have asked him but I thought it could be useful to discuss it here. I'd love to know what's your thought and experience on this. When I see movies that have a very define style, other then art direction, styling and lighting, grading wise are there look created specifically for the show? this looks are created by whom? colour scientist + colourist and dops prior the shooting or at the first grading sessions? This looks do they come to the grading room in a LUT form or luts are generally avoided in order to preserve the whole signal and avoid artefacts? Well, as usual way too many questions thanks, Orash

    Use built in LUT in Davinci?

    I usually just ask for the lut they used and load it. If it's not possible to ask for it, in the HD with the unloaded footage (if it's an arri alexa shoot) check if there is the .ale and see if with the Arri Meta extract you can retrive it

    Film flat scan

    Ok, I then have to ask to the lab that does the scan I know that dpx it's just a wrapper, I don't know the different scan log curve other then cineon

    Film flat scan

    Hi there. When a film has been scan flat (dpx) is It safe to assume that has been scanned using a cineon log curve or can It be something else? In that case using a cineon to rec709 lut would bring It back as shot? Cheers, Orash

    Minimum hardware requirement for a calibration laptop

    Thanks Bruno. In lightillusion website says: ADDITIONAL TECHNICAL & SUPPORT INFO. Operating System: Windows 7/8/10 PC Requirements: Minimal - 2Gig Ram Laptop, with HDMI Mac Operation: Runs on Mac using any Windows Emulation Unfortunatelly the first laptop i tried Met this requirement. Probably It was that laptop's fault anyway. I should try with another One running anche i5 CPU and see if It works

    Minimum hardware requirement for a calibration laptop

    I've checked lightillusion website, i couldn't find the info i needed, otherwise i wouldn't have asked here. I wanted to know roughly what people use as i have tried on a very very modest laptop with an i5 CPU and it was unusable (i think the problem is not the CPU but Just about everything else) Right now i'm running It on a Pretty good i7 laptop and It works fine but its an expensive laptop that i have been lendt and i have to give It back.
  8. Hi all! I'll have to get myself a new windows laptop where basically i will only run lightspace and maybe calman if i get a copy of it. As I will only need it for this I'll want to spend the least amount of money. Would you know what are the minimum requirement to run those software? cheers, Orash

    Supression LUT

    What do you use it for? I'd love to hear real world example. I'm scratching the surface of the Matrix potential and i want to really understand what Can be done

    Reduce edge contrast

    one doens't reverse the other in this kind of process, the blur node average pixel values, in that way the edges bleeds into each other as well as the rest of the image, sharpening after that micro contrast an image that has pixel values that are closer together, and while it tries to reverse the blur, at the same time the pixels changed from the original image, so a pixel that "belonged" to the bg now seems part of the fg. yeah, kind of hard to explain i guess. in very small amount it mix the image together and sometimes it's even hard to see the result using such small values, so it's not always worth the hassle, it helps with super sharp lenses. a similiar process i used to do to 3d elements when i was a compositor is to add grain and then denoise (before adding footage grain on top again at the end of the composite) that helped a lot to remove the cg feeling out of it

    Handle client micro managing versions

    I use versioning mostly to brake the remote grade link in this way i can set slightly different grade for continuity on long take. I'm afraid that keep adding stills i could easly get confused After a while, above all if the changes are microscopic. Maybe i should start using versions as you said and changing my workflow into local grades rather then remote.
  12. Hi all! I wanted to ask how do you handle versioning so you can go back to a previous grade when needed. I work in resolve so my workflow is based on what it provide, but i would be happy to hear also a software agnostic approach Usually if i do a grade and I have a revision to do, I save stills for all frames of the timeline in a stills folder with the date My problem comes with micro versioning: a real world scenario, I have done a job with the dop sitting next to me, we get to a point where is happy and asked me to export it out and upload it on vimeo so he could check it on his device (lets not talk about this problem ) then he said, ok, all good but i want to de sat a tiny bit everything (done, export, upload on vimeo) Then he said, alright, you know what maybe this few shots you can cool them down a little bit (done, export, upload on vimeo) He goes, sleep on it, then watch all 3 links and come back saying that he likes it better version01 and some clips of version02 Unfortunatelly since were such small and quick turnaround I didn't save stills everytime and i didn't add more nodes as i didn't want to over complicate the node tree. So when he got back i had to manually go back to what i have done in V01. I wanted to know if you have a better and easier workflow. cheers, Orash

    Gamma on consumer tv

    Yeah, that would have been my next question. Nits.

    Gamma on consumer tv

    Hi all! I got myself anche LG c7 TV and while going through the menu i've noticed that by default It's set to have a 2.2 gamma. The other options are 1.9, 2.4 and bt1886. The made me wonder and i checked some Friends TV (don't remember the model nor the maker) and either didn't have any option or was defaulting to 2.2. So i ask, is It stll revelant to calibrate to 2.4 our reference display? If tvs are setting they'r display to 2.2 and most of the people aren't going to change It, would not be better to calibrate to 2.2? What you think? Cheers, Orash
