✔ 最佳答案
Color contrast係顏色對比度,越高光暗越分明,將相會比較搶眼,但層次感越低,由於增高對比度會令光位更光,暗位更暗,有機會令原本冇咁暗既地方都變咗好暗,冇咁光既地方都變咗好光.要適可而止.
Color saturation其實同Color contrast異曲同工,佢係顏色飽和度.越高顏色越深,將相會比較搶眼,但層次感越低,由於增高對比度會令顏色變深,有機會令原本同深色比較接近既淺色變到同深色一樣.兩隻色變到得翻一隻色,所以又係要適可而止.
Color tone就係顏色係偏綠定係偏洋紅,有啲相機叫Hue,除咗色溫外,呢個係另一個改變顏色傾向的原素.舉個例,在燈光偏黃的環境,單單調較白平衡會有個現象係一係唔夠白,到夠白既時候又好似有啲偏藍感,這時將Hue調翻小小偏洋紅就可以減小偏藍感.
我覺得你三個因素都可能出咗問題,你可以試下分別改變佢地睇下個影響,仲有紅色對數碼相機來講係比較難處理的,好容易就會黐埋一舊.通常紅色多的環境以上設定適宜比平時低點.
