Exposing using EL ZONE in post & creating MONITOR LUTs 

Sorry guys, it's been pointed out to me that the EL Zone name is patented, which I hadn't realized when I made this video, so I've had to delete the files I had available for download.

That's two-for-two in extremely useful findings/videos in quick succession‼ Thank you very much.🙌

You my friend are achieving GOAT status. You're uploading a video on exactly what I was looking for at exactly the right time, ON YOUR FIRST TWO VIDEOS EVER. That's crazy.

This is really useful, thanks a lot! Exactly what I was searching for. I've double checked if the values are correct by using other DCTLs, and everything works like expected :). Can't wait to use it on shoots too.

Thanks a lot! This DCTL is just what I was looking for!

Is this useful to you, or is it just me? Sorry about the crappy audio by the way. I'll take more care with the mic next time!

Dude! This is great! Thank you so much! Massively useful!

For those trying to add the LUT to a Blackmagic camera - I had to save the LUT under 33 point Cube to create a smaller file. I was then able to add the LUT to my 6K Full frame Black Magic camera. So far its working

Man, the amount of work put into that to just release it for free! i have been searching some way to use EL zone for months and wasnt able to find anything paid besides the smallhd monitors you are a savior!

wow! just has this crazy thought about making a targeted LUT for certain log to translate it to EL Zone on any monitor system.... it's real!! thanks so much!!

Very helpful thanks. Will attempt to create the DCTL and export a LUT to try on my Blackmagic camera. Very useful tool.

bravo! just what i was searching for! subscribing...

Incredible tool.

More content please! Amazing videos

I tested it today with Pocket 4k and it is on the money accurate. A lightmeter read out on gray card exposed at 400 ISO |24F showed exactly the same F-stop the camera registered. I am so impressed! The only thing that I wish we could do is put on the screen the actual Legend | Map of colors

this is genuis!!

Ah, so gutted the DCTL has been removed. That's a huge disappointment after seeing the potential it had to make my life easier. I understand there is a patent, but damn if that hasn't ruined my Monday. Thanks for making the effort @Diodefilms!

Thank you so much, I've been looking to using EL ZONE but can't update my monitors yet. Will report if the LUT matches the greycards on an SXT+.

Ive got a blackmagic video assist which allows for recording BlackmagicRAW but it still counts the colourspace as V-log. Would it work for that situation?

Hey Man, great video! I was wondering what made you stop sharing the DCTL. I'm planning to make a video about exposure and contrast ratio and share something similar as well. Do you think there is a way to share it without legal consequences? Did you receive any message telling you to put it down? I just think it's crazy that a LUT can infringe a copyright. Anyway great video

I tired to import the sony slog3cine from your github into my fx3 and my atomos monitor it didnt work i assume its 66 point. I brought the "github slog3.cine.cube" into resolve (worked great) I generated a 33 point version of that lut. when i look at the image with the lut as a node in resolve the middle grey parts are grey but when i use the "generated lut" on my atomos monitor (no lut on resolve node) the same image from resolve there is no grey for middle grey. Middle grey goes green or yellow. any ideas? i also tried to go CST linear + el zone linear DCSTL to generate a 33 point cube but it yields same lack of middle grey results.

Hi Great video! Where did you download the colorbar image from?

This is great thanks. I was hoping someone would do this. With Red Komodo I've noticed slight discrepancies between my light meter, Red's in camera 'Gioscope' and the EL Zone on my small HD. It's only between a stop and a half stop but still Interesting. It may be the 'range' of values being used ...i..e..exactly when does one color change to another between the stops. Or perhaps my meter needs recalibrating. Need to investigate further.

Is it possible to have a version of this for final cut or premier?

Hi, thanks for making this. Is it possible to add the CST into the DCTL so we only need to use one node by adding the option to change input color space and gamma as well as output color space in the DCTL settings interface? This way there would be no option to use a different output than linear or a different tone mapping than none. So not only would the workflow be cleaner because we do not need a second node, it would also have less possibilities for user errors. Thanks.

Hey! Great video, and amazing that you’re giving the DCTL away for free. You seem like a pretty smart guy, so I have a question for you! I’ve currently been using the EL Zone via my Small HD. Ed Lochman (Sp?) calls for a log image to get the most out of the EL Zone System, which is actually what you’re required to do if you want to use the function in the monitor. That said - say I’m wanting to use some reference images to replicate a look I’ve seen in a film… If I take a screenshot from say… Sicario, it’s obviously a graded, non log, image that has been manipulated tremendously from what started in the pipeline… But what I should be really looking at is the ratios within the scene, because in theory - if I get the ratios right, I can manipulate the levels using an exposure (offset, or exp DCTL) adjustment and it will still retain the look from the reference. Am I thinking about this correctly?

This seems to work with my osee limon 5. Im going to try it my fx30 next!

the arri luts dont seem to work, is there any way you can help?

Great work! But too bad, neither the LUT nor the DCTL works. I have also tested the LUT on the monitor but nothing is displayed there either. Any idea?

The question has been raised if whether this is an illegal implementation that violates the El Zone IP and patent? Any thoughts or comments regarding this? It might be a positive to explain the differences of your implementation.

I've been looking for this! Thank you! Could you make a Z Cam version for zlog2?

you had mentioned that this is for an 8 bit source is there any friction using this in a 10 bit or higher workflow?

This is fantastic, well done! Too late for the download but easy enough to rewrite my own code. Works great in Resolve, however, when I make a LUT the DCTL node is ignored, so I get a LUT with just the CST to Linear. Any ideas why?

you have another cst node after your e.zone node, what is that used for. thanks

Is there a way I can modify this to be for HDR?

I love what you have done! I tried to download the Lut for BMD to my 6k Pro, but every time it says that the transfer failed so I can’t actually see if it works. Have you run into this problem? If so do you have any suggestions as to how to resolve it it? Thank you again for making this accessible!

Do you sell the DCTL for the EL Zone system? I’m clueless on how to make one. I want to study other films using the DCTL.

AI helped me to generate code for this. It works nice inside davinci when log converted to linear before the DCTL node. I converted it to .vlt LUT and put into my lumix S5iix but everything is so dark on camera monitor.

I shoot on a Sony FX 30 and would love to be able to make use of this but when I went to your lake it won’t let me download anything. Can you send me the link so that I can download your various sluts and things for colour grading with this tool that I can download into da Vinci Resolve and onto my monitor for luts

Hello, is there any workflow with resolve to see the EL Zone system on movie grabs? To analyze them. To learn about ratio etc

I'm. not getting the same colors as the chart using Cullens exposure DCTL to feed the stops into your DCTL - some are correct but some are way off. Are you sure the colors are inputted into the DCTL correctly?

hy, is there any way to get the lut now?

cant figure this out,el zone saying exposure is good,but when you turn it off image is dark. using slog 2 and s-gamut from sony A7iii

how did you create or where did you get the Exposure DCTL?

Is their a way to creat a lut with an overlay of the range?

I'm by no means a dctl builder. But wouldn't a chart to add on top on this dctl a good idea as an add on.?

If I were to recreate this and use it for 10 bit, would that help the quality of the lot?

Any chance you can make a LUT for Davinci Wide Gamut?

Why not to add more stops? 🤔, some cameras have a wider dynamic range

Can work on color management?

And also, the logC3 is only 2 bytes and doesn't work.

Great video still, and you inspired me to replicate a version of my own, this is a super helpful tool for anyone shooting with a camera in LOG. Had no prior knowledge to coding. Took me quite a few days to figure out the coding part as well as all the various Log curve data by the various manufacturers. I created a DCTL that lets you select what Log curve you are using, and I also decided to use the Log curve data so it is not only accurate but also you won't need a CST to use it with. But of course not all sensor performs the same, so adjustments may still be needed depending on the camera you're using. My reference table has data not just for whole stops, but also in 0.1 stop increments. If anyone wants to have a look at the reference table, I can share them. I suppose creating your own version with data available won't be considered breaching of copyright laws right?
