================================================================ fpsup-raw-view v0.2.2test SIGMA fp — RAW monitoring: the LCD shows what 12-bit CinemaDNG records ================================================================ English below the line of dashes; 中文在後面。 Illustrated explainer (EN / 简 / 繁): https://ijigen.github.io/fpSup/explainers/raw-view.html WHAT IT IS Adds "RAW" as the 17th row of the COLOR menu. With it selected and the camera recording CinemaDNG 12-bit, live view shows the RAW the camera is about to record, not a finished picture: - Standby uses the recording gain. What clips on the screen clips in the DNG, and what does not, does not. - Sensor saturation is display white at every ISO. - Two curves, chosen with the box on the right of the RAW row (the box shows SA or GA): SA Latitude, Stop Aligned: the per-ISO latitude of the fp (stops above and below 18% grey) spread over the screen with Rec.709's own stop spacing. GA Latitude, Gray Aligned: the "LA - SIGMA Rec709" curves of SIGMA fp Rec709 LUT & Operations Guide v3 (Ole Berek). Both use the latitude figures from that guide. Two settings on the AEL page do something different in RAW: - Contrast: how the bottom of the latitude is shown. Monitoring only; the CinemaDNG is not affected. 0 all 12.5 stops fit on the screen. The live view can resolve only about 10.9 stops below clipping, so the bottom ~1.6 stops show as fine noise dots: dots mean there is detail, pure black means crushed. +0.2 only the 10.9 stops the live view resolves; the bottom ~1.6 stops go black and the rest get more room. - Saturation: whether the camera's colour calibration is used. 0 the default. No calibration on screen, and the CinemaDNG is exactly the same as a normal recording. +0.2 the camera's own calibration matrix (the one the other colour modes use) is applied on screen AND written into the CinemaDNG ColorMatrix tags, so Resolve shows the colours you monitored. The raw pixels are not changed. - Sharpness is held at 0 while RAW is on. The recorded raw data is not altered. **Firmware Ver.5.02 only.** Test build. WHAT CHANGED SINCE v0.2.1test - Playback is stock again. With RAW on, CinemaDNG clips played back on the camera through the RAW view curve for the current ISO, and lost their own ISO gain, so an ISO 100 and an ISO 800 clip looked equally bright. Playback now looks exactly as it does in any other colour mode; RAW view comes back when you return to shooting. Since v0.2.0test: - RAW is remembered across a power-off, with SA/GA, Contrast and Saturation: start the camera and it comes back in RAW as you left it. (Saved at a normal power-off; see LIMITS.) - Half the size, so it now fits in fpSup-Merge together with the shell, gyro and open gate. The camera works the curves out at start-up instead of carrying them on the card. - SA near clipping is closer to its design curve (v0.2.0test was up to 0.5% off there); GA is unchanged. Since v0.1.0test: SA follows Rec.709's stop spacing; Contrast and Saturation became 0 / +0.2; crushed shadows always read black; the box on the RAW row shows SA / GA. TWO CARDS IN THIS FOLDER Ordinary card (this folder): AutoRun.txt + fpSup.BIN Every start runs the AutoRun: a progress bar, then the banner fpSup-RAW-v0.2.2test! Fast Start 2 (FastStart2/): AutoRun.txt + fpSup.BIN + FPSUPUI/ After the first start, a restart with the power switch loads about 1.4 s after power-on without the AutoRun and shows the four-box screen; a cold start runs a short AutoRun. It stores the loader in the camera's settings block, which survives a battery pull. Power off with the USB cable UNPLUGGED -- with it attached the next start is always a cold one. Updating from v0.1.0test's Fast Start 2 card: the first start after copying may still run the old one; judge from the start after that. The two zips hold the same files, one card each. INSTALL 1. Copy the card's files to the ROOT of the SD card the camera boots from (for Fast Start 2, the FPSUPUI folder too). 2. Start the camera with the USB cable unplugged. 3. Recording format CinemaDNG, 12-bit. COLOR menu -> row 17, RAW. LIMITS - CinemaDNG 12-bit only. MOV and 8/10-bit are not supported. UHD records 8-bit CinemaDNG: in UHD the screen jumps about one stop brighter when recording starts. - RAW is saved at a normal power-off only; after a battery pull the last change is lost, as with the camera's own settings. It is not saved while a custom mode (C1-C3) is active. - RAW is saved as a colour mode the stock firmware does not know. Started WITHOUT this card, the camera shows Standard; pick any colour mode to clear it, or put the card back. Without the card, avoid the COLOR button menu while it shows Standard: it can change Standard's saved adjustments. - Choosing OFF in Quick Set does not leave RAW; choose OFF (or another mode) in the COLOR menu. - Auto exposure can meter up to 1-2 EV darker than stock in scenes with bright highlights: live view now has the highlight room 12-bit recording has. - In fpSup-Merge it combines with the shell, gyro and open gate. REMOVE Delete the files (or take the card out) and switch the camera off. Every firmware word the card changed is written back as the camera powers off. A Fast Start 2 loader left in the settings block does nothing without its card. ---------------------------------------------------------------- fpsup-raw-view v0.2.2test SIGMA fp —— RAW 監看:螢幕顯示 12-bit CinemaDNG 實際錄到的東西 ---------------------------------------------------------------- 圖解說明(EN / 简 / 繁): https://ijigen.github.io/fpSup/explainers/raw-view.html 這是什麼 在 COLOR(色彩模式)選單加上第 17 列「RAW」。選到它、而且錄影格式是 CinemaDNG 12-bit 時,即時影像顯示的是即將錄下的 RAW,而不是修飾過的畫面: - 待機使用錄影時的增益:螢幕上過曝的地方 DNG 也過曝,沒過曝的就沒有。 - 每個 ISO 的感光元件飽和 = 顯示白。 - 兩條曲線,用 RAW 列右側的框選(框上顯示 SA 或 GA): SA Latitude — Stop Aligned:fp 各 ISO 的寬容度(中灰以上、以下幾檔), 依 Rec.709 本身的檔距鋪在螢幕上。 GA Latitude — Gray Aligned:SIGMA fp Rec709 LUT & Operations Guide v3 (Ole Berek)的「LA - SIGMA Rec709」曲線。 兩者都用這份指南的寬容度數據。 RAW 時 AEL 頁有兩項作用不同: - 對比度:寬容度底部怎麼顯示。只影響監看,CinemaDNG 不受影響。 0 12.5 檔全部放進螢幕。預覽在削波以下只分得出約 10.9 檔, 所以最底約 1.6 檔以細小噪點出現:有點就是有細節,純黑才是壓死。 +0.2 只放預覽分得出的 10.9 檔;最底約 1.6 檔變黑,其餘檔位更寬。 - 飽和度:要不要用相機的色彩校正。 0 預設。螢幕不套校正,CinemaDNG 與一般錄下的檔案完全相同。 +0.2 螢幕套用相機自己的校色矩陣(其他色彩模式用的那一組), 同一組也寫進 CinemaDNG 的 ColorMatrix,Resolve 顯示的顏色與監看一致。 RAW 像素本身不動。 - RAW 時清晰度固定為 0。 錄下的 RAW 資料不會被改動。 **僅限韌體 Ver.5.02。** 測試版。 與 v0.2.1test 的差別 - 回放恢復原廠顯示。RAW 開著時,相機回放 CinemaDNG 會套用目前 ISO 的 RAW 監看曲線, 而且片段自己的 ISO 增益被抹掉,所以 ISO 100 和 ISO 800 的片段看起來一樣亮。 現在回放和其他色彩模式完全一樣;回到拍攝畫面時 RAW 監看自動恢復。 自 v0.2.0test 起: - 關機後會記住 RAW,連同 SA/GA、對比度、飽和度:開機後自動回到上次的 RAW 設定。 (正常關機時存檔;見「限制」。) - 大小減半,現在可以在 fpSup-Merge 裡和 shell、陀螺儀、open gate 一起合併。 曲線改由相機開機時計算,不再整份帶在卡上。 - SA 在削波附近更接近設計曲線(v0.2.0test 在那裡最多偏 0.5%);GA 不變。 自 v0.1.0test 起:SA 依 Rec.709 檔距;對比度與飽和度改為 0 / +0.2; 壓死的暗部一定顯示純黑;RAW 列右側的框顯示 SA / GA。 這個資料夾裡有兩張卡 一般卡(本資料夾): AutoRun.txt + fpSup.BIN 每次開機都跑 AutoRun:進度條,然後顯示 fpSup-RAW-v0.2.2test! Fast Start 2(FastStart2/): AutoRun.txt + fpSup.BIN + FPSUPUI/ 第一次開機之後,撥電源開關重開時約 1.4 秒就載入、不跑 AutoRun, 顯示四格畫面;冷開機跑短版 AutoRun。會把 loader 存進相機設定區 (拔電池也會留著)。關機時請**拔掉 USB 線**——插著線關機,下次一定是冷開機。 從 v0.1.0test 的 Fast Start 2 卡更新:複製後第一次開機可能仍跑舊版, 請以再下一次開機為準。 兩個 zip 裡是同樣的檔案,各一張卡。 安裝 1. 把卡的檔案複製到相機開機用的 SD 卡**根目錄** (Fast Start 2 要連 FPSUPUI 資料夾一起)。 2. 不插 USB 線開機。 3. 錄影格式選 CinemaDNG 12-bit,COLOR 選單 → 第 17 列 RAW。 限制 - 只支援 CinemaDNG 12-bit。MOV 與 8/10-bit 不支援。 UHD 錄的是 8-bit CinemaDNG:UHD 下開始錄影時畫面會亮約一檔。 - 只在正常關機時存檔;拔電池會失去最後一次的改動,和相機自己的設定一樣。 使用自訂模式(C1–C3)時不會存 RAW。 - RAW 是以原廠不認得的色彩模式存檔。**不插這張卡**開機時相機會顯示 Standard; 選任一個色彩模式即可清掉,或插回卡。沒插卡時顯示 Standard 的期間, 請避免打開 COLOR 按鈕選單:它可能改到 Standard 存的調整值。 - 在 QS(快速設定)選 OFF 不會離開 RAW;請在 COLOR 選單選 OFF 或其他模式。 - 場景有亮部時,自動曝光可能比原廠暗 1~2 EV:即時影像現在有 12-bit 錄影 同樣的高光空間。 - 在 fpSup-Merge 裡可以和 shell、陀螺儀、open gate 合併。 移除 刪掉檔案(或拔卡),然後關機。卡片改過的每個韌體字,會在相機關機時寫回。 Fast Start 2 留在設定區的 loader 沒有卡就不會做任何事。
