I´ve seen this video already several years ago and since then I always remember: "Cameras and lenses are just like people - they´re all different individuals". It´s one of these iconic sentences in your life. Since I learned this it helped a lot of my customers to understand why they need an video engineer. THANK YOU Steve! Your explanation on the Double diamond is the best I ever heard. It helped me a lot.
Thank you for your kind words. Yup, it's an old video & I've since retired 3 years ago. The design of live television cameras has evolved a lot over my 46 years in the business, but the concept & effort for quality imaging will always remain, because the final receiver will always be deep within our human brain.
The Video/Shading lesson that keeps on giving... Thanks, Steve. I put this to use last week (April 2023) to match and balance cameras. Truly helped, thx!
Steve, This is a great presentation. I found it looking for ways to adjust saturation level in a broadcast camera. My controller only seems to have Red and blue gain, red and blue black level, and knee. What do I use to control saturation?
@@KSARSaratoga is it a proper shading/painting control panel or are you just using the ccu front panel? ccu front panel usually just has what you listed.
OMG... THANK YOU! 😄 I realise this video is really old but I just wanted to say thanks nonetheless! How has nobody ever taught me this double diamond line up technique before? I saw a guy using it today on a job and was intrigued, and this video has made it clear how much more effective the double diamond is compared to the standard scope or RGB parade. Every day's a school day! 👍
"Let's go to Camera 2 - oh boy" :D A great quickfire explainer, I'll be sure to give the double diamond a spin next time I have to go fix a borked scenefile ;-)
The lightning display (found in the "vector" menu) can be magnified by hitting the "gain" button. I prefer choosing a vertical gain of 5x. It's up to you. (Remember, there is no magnification for the double diamond, residing in the "gamut" menu)
Thanks Steve, i dont use Double Diamond in my studio but wanted to learn another way to read and improve my video shading. does anyone know what the best use case for Double Diamond is? I am assuming outdoor shoots? because of the harsh lighting? Edit: Thanks Steve, been using Tektronix scope and Waveform for over 10 years and always appreciate learning and the Double Diamond is new to me, Ive been practicing with it on my shows here and there because of this video so thank you
Yeah, well you can't use "double diamond" or "lightning" displays in your studio because you don't have a Tektronix scope. If you did, you would have already been using it. Think of it this way: While viewing at a traditional vector scope, you are literally looking down the barrel of of a pencil with the pointed lead aimed at your face. You can't see where color differences are, from zero black to 100 white. Now, rotate that same pencil so that you can see the eraser on the bottom and the point on the top. You now have revealed the color arrangement all along the axis from zero to 100. Now you know exactly where to fix. . . black, gamma, white and everything in between and with respect to R,G,B,Y,M,C No more guessing!
@@stevechauncey5034 Thanks for the info Steve, just a heads up i have been using Tektronix for a little of 10 years just never used double diamond. I have already experimented with this in my studio since ive seen the video and appreciate the info and expanding my knowledge of the instruments i use at work
@@gregmeli951 Great! And the beauty of it: The "Lightning" display is expandable for viewing black level judgements, plus, you can measure luminance as well as chrominance, all in one waveform!
The lightning display is an option found when selecting "Vector" on the tekronix WFM. Incidentally, I have found the lighting display to be quite similar to the diamond display, enough so, that I now use lightning exclusively!
That's correct, it's proprietary to Tektronix. To be clear, the diamond display is within the gamut menu and the lighting display is within the vector menu.
Hello Steve and all. I have a quick question please. In the beginning you turned MATRIX OFF; do you keep it OFF or you turn it back ON again after you finish chipping and matching the cameras? Thanks.
Excellent question: The matrix function in today's HD world is a tool that can't be ignored. It provides the opportunity to enhance hues, saturation & tone to make average set & lighting look great, and great set & lighting look stunningly beautiful. When we initially look at a group of unknown cameras & lenses I think it’s necessary to first attack the fundamental set ups to insure a foundational match without the "next level" matrix function in force. When that's achieved you're ready to have fun. Turn on the matrix & with your scope & ChromaDuMonde chip chart, you’re now able to create a new "origin" of color for the video. Keep that matrix on going forth when you "chip", until the production is completed so you can maintain your "special look." The next production engineer using those cameras along with other cameras will want to install something different, and the process begins again.
So do I open up iris to reach top point and bottom point of diamond on every camera as soon as LD is set? Also you said adjusting peds, is that the blacks? Or gammas?
With all cameras focused on the chart, where you set your iris (in my opinion) is up to you. I like to settle somewhere between 80% and 90% of ire. Some like to peak at 100%. Whatever floats your boat. . . Pedestal & black level. . . it's all the same to me!
@@chrisoakleyfx Good point Chris - so what I do is cancel knee function while on chart, then re-introduce it during production. I use a favorite setting for the knee, but I can always adjust it if conditions change.
There's a plethora of "buttons" on a video console-desk (used in combination) that one can exploit in the effort of "expanding color." However, if you're looking for "what button," think about the one situated right between your eyes. . .
In the brief demonstration, I simply amplified saturation, but in practice, I prefer enhancing the user matrix, where color & hue assessment can be re-defined resulting with richer colors, without over amplifying unwanted color values.
Our need for video measurement is, and always will be, what it is. An updated explanation of the fundamentals for digital color video calibration now with the Tektronix "gamut - double diamond" and "vector - lightning" displays isn't necessary. . . and it's still true for the center vector display created for the 1953 analog color NTSC agreement. Whatever scope you're privileged to access, those fundamentals remain.
HI Steve, thanks so much for this informative video. I bought a Tektronix unit just because of this video. I assume you want to white balance the cameras when you zero out the settings? white balance prior to using the chip chart?
You can always use the white balance function when you begin, however, I prefer to white balance on the chart manually. It's like putting your own signature on the set-up!
Of course gamma refers to the "middle", between black and white - the gray area. Skin levels are reflected in this range and the best way to match multi-camera skin tone color, is by adjusting RGB gamma control. In this way, previously adjusted white & black balances, will be preserved.
The double diamond display is a proprietary function found only on Tektronix scopes. It is accessed by selecting the "Gamut" button. The lighting display is accessed by selecting the "Vector" button.
Nor do the makers of this video I'm sure, but that doesn't mean they won't have jobs or opportunities to work with this or similar industry standard equipment.
Hi Steve, question for you. When you added more colors to the cameras manually while looking at the scene how did you do this? Did you use all three colors and in both whites and the blacks?
During the demonstration, I simply amplified the overall chroma saturation. You could also amplify, all or any combination of red green & blue - or - select a preset matrix - or - redefine the user matrix origin.
If you wanna adjust each color channel individually, then use multi-matrix feature which includes both hue and saturation adjustment abilities without. In tv set I just switch on the main matrix button to get the scene more saturated in terms of red and blue channels. Of course these features are present in prosumer cameras mostly.
@@stevechauncey5034 You're the boss, thank you for helping us kids. Ya know, they say this is a kids game, but I do enjoy learning and really enjoy your perspective and style. THANK YOU!
"Cal-pulse" is short for calibration pulse. It's a perfect frame of video generated by the camera proving the state of its RGB matrix process without a lens image.

It’s a proprietary Tektronix test pattern. The scope has to have it as an option. It’s the button called gamut on the scope.
