很多人沒留意影出來的照片,曝光Dynamic Range不足,暗位未出光位巳爆晒

數碼相機一般原相直出都有,曝光Dynamic Range不足問題.

依靠PS作後期處理,也因每個人技術參差,未能有滿意效果.

其實最佳方法是,自定相機內的曝光曲線(Tone Curve) or (Contrast Curve).

用原廠Software 自定完曝光曲線,再Load回相機.在相機set番用custom tone或custom curve.

用(P/S/A/M mode)去影相,就會有很自然真實曝光的相片.

Nikon 專用軟件是Nikon Capture (舊型號如 D100 D70. D70s..e.g.).
新型號如 D300/D80/D40..e.g用Camera Control Pro.

Canon用家,不記得軟件名稱,可上網找找 google search (Tone Curve or 自定曲線)

用tone curve 暗位清楚自然,光位唔爆 good
