DCP TIFF

意図:技術者または非技術者がメーターを使用せずに画像と音質の変化を判断するのに役立つ資料を提供します。

If the test equipment isn’t scheduled at the auditorium for another 6 months, is there a way to tell if the the contrast and color display is degrading? These TIFF slides are experiments to answer this question, and supply tools if it is possible. Suggestions are welcome. All these TIFF plates are 4096 x 2160, 2020 color space with 16 bits of depthiness, unless otherwise mentioned. Sound files from the DCPs will get their own page, but don’t go looking for it now…

White2Blackダイヤル このTIFFは、画面全体で100から0までの滑らかさを確認する実験として始まりました。本当に、それはカラープリントとして印象的であったので、論理的な極端はどこでも黒から白でした。セットには3つのバージョンがあり、それぞれがグラデーションの中心点を中心から片側またはもう一方に少し押します。ご自身の責任でそれらを混同してください。そして、それぞれにダイヤル付きのバージョンがあります。 DCPを作成するときは、ダイヤルを使用せずに才能が判断できるように、次々に使用し、問題がある場所をマークダウンします。 TIFFファイルのダイヤルは、ここで圧縮されているものよりもずっと良く見えます。それらを試してみて、私たちに知らせてください。常に、16ビット、2020およびパスコードは QA_b4_QCWhite to Black dials Brighter and 709   White Squares with a Radial Gradient and Scale

4色、10ボックスTIFF Once more, an attempt to see what can be seen in HDR / EXR projector systems, then to find which ones can be used to notice any degradation in the system. These would be the normal SMPTE required RP 431-2 set of blocks going across, but they also have a smooth gradient going across the bottom. …and, they don’t start at 100%. There are 3 sets, one which starts at 10% luminance and goes to 1%, another from 1% to 0.1, and – you guessed it, the 3rd set goes from 0.1% to 0.01%. Thus, with 65,535 as 16 bits, the range of these goes from 6,553 to 7 units of color. More specifics at the download page… For some reason, I made a Rec 709 PNG at 6554 – 655 with outline and it doesn’t seem to show on the computer screen. Well, just a bit if you look sharp. So, this is the 4th of this series, attempting to find an objective measurement technique to quantify changes. The link above gives you a set of TIFFs. And at this link (soon as it is made), there is a DCP。何が機能するか教えてください。 Sample of the Green colors with outline  


垂直メーターTIFF The question for these slides is “Can you objectively and consistently judge where the color ends and only black exists”? Will several people see the same ending point.  The underlying question is can the meters be used as tools to objectively judge contrast? If there is a lot of dust on the port window or in the room, will there be a difference? On each slide there are 16 bars of color, 8 starting at 5% luminance in the center and going to 0% at top and bottom, and 8 going from 2.5% and going to 0%. One the left is a set of 4 of each for RGB and White on the left, and the right side is a complete set, through in a different order. The idea was to see if a bright color like green made it too hard to judge the blue if they were adjacent. Indeed, these are experimental. In addition to 5/2.5, there is also a slide with 2.5% and 1% meters, and for those with an extraordinary system, 1% to o.1%. Is 5% a usable meter for each color or is 2.5% more useful in a xenon powered room? The theory is that one can look at the meter and make a substantially objective judgment, record it on one of the checklists, and use the test again a week or month later to note if there are changes. Wow! This PNG only begins to show a usable scale…download the TIFF file. Vertical meter of each primary color and black at 2 different luminance.  


コントラスト用のダイヤル:6%、4.5%、3%、1.5% RGBおよびグレー、目盛り付きおよびなし。 This idea is similar to the vertical meters above, but as dials with the gradient from 6% to 0% (as well as 4.5% and 3% and 1.5% to 0) on a dial, and in several colors. There is a version with a set of tic marks to note where the last point of seeable color is…and a version without. Why? Because it may be that one needs to spot the position of where the color disappears, without the influence of the dial markings, then get the markings later. In the DCP the dials show for 5 seconds then the dials with the tic marks and numbers show together for 5 seconds. Experiment and report please. RGB and Greys. 2020. 4K and 16 bits of depth for each color. All to see if we can get an objective tool that an interested and intelligent person can use. A little trouble making a file that shows on the screen at such low luminance. Try the TIFFs. GreenDial with tics marks in 709  


数字が汚れている灰色のステップ The classic row of grey boxes is defined in SMPTE RP 431-2: D-Cinema Quality – Reference Projector and Environment document. One row in the center of the screen. Problem is, it isn’t a very good test of a modern digital cinema projector, is it? This TIFF file has every square of grey from 2.5% to 100%, plus a ramp from 2.5% to 0%. And above that is a set of numbers, that give the luminance value of the square…but it gives it 3 times, and the digits are in three different values. The bottom value is 1% lower, and the middle is 0.1% lower and the top number…hopefully able to be seen in that fancy million to one system, is 0.01% different. The trick is to see if these numbers show up on a screen. Have fun and do share your thoughts. As always, 2020 color space and 16 bits of depthiness. The DCP is at: GreyStepScales These are the numbers that are laid on top of the squares…can your system produce differences for some or most of them? Numbers above grey steps x 40 Grey Steps x 40

Horizontal and Vertical Lines – Colored Lines, 2020, 4K What is the difference to a projector or a LED wall between drawn black lines and backgrounds of colors…which actually fill in the alternate lines, right? …and drawing the colors as the lines and letting the editing program put in the background…or no background at all.

2% Hmmm – What shall we call this? It is derived from the CST chart that marks off 2% rectangles to begin with, and a bunch of circles drawn at the proper 10% points…then it got botched up with moving the color wheels to align with the corner to corner lines which actually serve no purpose…ok, toss in some focus squares …that’ll distract them. (This png is 709…get the real thing in 2020 and tell us how to make it better please. Colors on a black background that also checks the sides in a colorful manner.

CJ’s Favorite Distraction Several variations with several colors going from full saturation to dark or white …and grey level tests too. A distraction because I keep refining it. Now with MTF marks – hope they work…haven’t tested them yet.
