Latitude → screen寬容度 → 屏幕

Left: the fp’s latitude at each ISO in stops from 18% grey (12-bit CinemaDNG; figures from SIGMA and Ole Berek’s SIGMA fp Rec709 LUT & Operations Guide v3, used by both SA and GA). Each line shows where that stop lands on the 709 screen. Pick an ISO below or click a column.

左邊是 fp 各 ISO 的寬容度,單位是離 18% 中灰幾檔(12-bit CinemaDNG;數據來自 SIGMA 與 Ole Berek《SIGMA fp Rec709 LUT & Operations Guide v3》,SA 與 GA 都用它)。每條連線表示那一檔落在 709 屏幕的哪個高度。在下面選 ISO,或直接點柱子。

Contrast: the bottom 1.6 stops對比度:最底 1.6 檔

The live view’s tone table has 2048 entries with clipping at entry 1918, so the darkest entry it can tell apart sits 10.9 stops below clipping. The fp holds 12.5 stops, so the bottom ~1.6 stops (the lighter segment of each column) fall between entries 0 and 1. Measured on the camera: the table is not interpolated, so this range shows up only as noise-dot density.

機身預覽的色調錶有 2048 格,削波在第 1918 格,最暗能分辨的一格離削波 10.9 檔。fp 有 12.5 檔,所以最底約 1.6 檔(每列顏色較淺的一段)都落在第 0 格和第 1 格之間。實測查表不插值,這段只會以噪點疏密出現。

0bottom 1.6 stops shown顯示最底 1.6 檔

SA: all 12.5 stops on screen with 709’s stop spacing; the floor sits at the LCD black level.SA:12.5 檔全部按 709 檔距放進屏幕,底部落在液晶黑位。
GA: a toe lifts the darkest live-view entry to 10%, then rejoins the guide’s curve; above middle grey it is the guide’s.GA:暗部加一段墊腳,預覽最暗一格顯示 10%,再接回指南曲線;中灰以上與指南相同。
The bottom stops show as dots that thin out as it gets darker: dots mean detail, pure black means crushed.最底幾檔以越暗越稀疏的噪點出現:有點就是有細節,純黑才是壓死。

+0.2bottom 1.6 stops dropped去掉最底 1.6 檔

SA: only the 10.9 stops the live view resolves, with 709’s stop spacing; each stop gets more room.SA:只放預覽分得出的 10.9 檔,按 709 檔距,每檔更寬。
GA: exactly the guide’s LUT. The darkest stops sit below the LCD black level.GA:完全按指南 LUT,最暗幾檔落在液晶黑位以下。
The bottom stops are black: you can’t tell detail from crushed there.最底幾檔全黑,分不出有沒有壓死。

Effect on CinemaDNG: none. Contrast only changes the monitoring tone table; files shot with either setting are identical.

對 CinemaDNG 的影響:沒有。對比度只改監看用的色調錶,兩種設置錄下的檔案完全相同。

Saturation: the colour matrix飽和度:色彩矩陣

In RAW mode, Saturation does not adjust vividness; it chooses whether the camera’s own colour calibration is used.

RAW 模式下,飽和度不是調顏色濃淡,而是決定要不要用相機自己的色彩校正。

0no matrix (default)不套矩陣(預設)

Sensor RGB shown directly, as in the stock OFF mode.直接顯示傳感器 RGB,與原廠 OFF 相同。
The CinemaDNG is exactly the same as a normal recording.CinemaDNG 與一般錄下的檔案完全相同。
Colours look washed out; use it for brightness and exposure.顏色偏淡,適合只看亮度與曝光。

+0.2fp calibration matrixfp 校色矩陣

The camera’s own calibration matrix (the one the other colour modes use) is applied on screen.屏幕套用相機自己的校色矩陣(其他色彩模式用的那一組)。
The same matrix is written into the CinemaDNG ColorMatrix, so Resolve shows the colours you monitored. Raw pixels are untouched.同一組矩陣寫進 CinemaDNG 的 ColorMatrix,Resolve 顯示的顏色與監看一致。RAW 像素不動。
Use it to judge skin tones and colour.適合判斷膚色與色彩。
