對呀~~一樣呀~~色調補償用自訂曲線~不過我想跟鏡頭的發色也有關係~我的a09本來就有點軟黃~我覺得用這個曲線拍風景的話可能要-ev值不然會有點過曝~~這是小弟的感覺~
我要表達的是，藝術或生活。
準色溫色調，也許無法傳遞相片中的意涵
1+1=2很簡單
但我希望的是1+1＞2
將生活提昇為比2大，也許不是色溫色調准不準的議題
小弟也只是拍拍兒子、外出旅遊的回憶，談不上去創造藝術！nomrd wrote:

貢獻一下 sReala Version 2 小的測試之後感覺不太出來差異
把原文po一些上來 轉載自 The Digital Knowledge Base
跟之前樓主發表的分別是version1 & 2
sReala version 2 Tone curve User Features
- Essentially a correctional custom tone curve for the Nikon D70
- Corrects underexposure
- Maximises the total amount of detail captured by the Nikon D70 sensor
- Maximises details captured from black to white
- No bias on any part of the linear tone data
- E.g. no tonal shifting
- No colour shifting
- No un-natural re-production of tonal response
- Tone curve is calibrated to capture pure RAW accuracy
- Captures accurate colours
- Captures accurate contrast
- Curve is scientifically measured using charts to maximise the capability of the Nikon D70's digital sensor, see the technical specification for more details...
Technical Specification
- Calibrated based on 18% gray output
- Measured at 119 for 18% gray output based on RGB 709 CV data ouput values
- Calibrated to capture much more highlight detail
- Highlight mapping to147 to achieve pure white based on measured values
- Calibrated based on colour chart
- Measured the output of each colour square on the chart
- Tweaked the curve points to ensure the output data of the tone curve matches EXACTLY the expected reflectance of each colour on the colour chart.
- Tweaked the gamma to ensure exposure correction based on the reflectance output of cell 7 or medium gray from the colour chart based on an RGB 709 CV value of 119.
- Measuring the colour and gray scale based on charts the curve was tweaked to re-map the sensor exactly using the tone curve based on the reflectance data of the charts.
- This ensure pure accuracy, exposure correction and accurate colour output
- All these calibrations are within the contraints of the Nikon D70's digital sensor
- Calibrated on firmware version 2 and tested on version 1
Tone Curve Calibration information
- 2 different Nikon D70 bodies to calculate the difference in metering to produce a tone with an average exposure
- Assortment of lenses to calculate a target average exposure and calibration
- Measured using aRGB colour space to ensure the colour values from the colour chart were accurate and fair
- Camera settings : Hue 0, Sharpening 0, WB preset custom
- Measured tonal output from NEF data
- Colour Chart
- Grayscale chart
