1). Luma is special parameter which is independant to Temporal/Spatial denoise parameters. Luma is somehow like the basis of whole picture. If getting more detail and clear picture, the less work of denoise tuning via Temporal/Spatial. 2). The denoise parameters - Temporal/Spatial must adjust together with the same value but the direction is inversely. - Temporal parameters all take "positive" value and its max value <=Luma(i.e. Temporal_A <=Luma_A & Temporal_B <=Luma_B). Once done it, the Spatial parameters tall take "negative" value from Temporal(i.e. Spatial_A = - Temporal_A, Spatial_B=-Temporal_B. 這樣設定背後含意: 先將 Temporal denoise 設定到最大值與 Spatial denoise 設定到最 小值為開始調整起始; 若太糊表示denoise過頭, 將 Temporal 往下調一格值而 Spatial 往上調一格值... 一直重複這樣的步驟直到找到最佳組合值 3). Night Sight 拍出來糊糊的, 要到 Sharpness 把 Night Sight Sharpness Delta factor 設 到最大值31 4). The setup either Luma or Luma denoise, you just can choose one and cannot set it up both. If you set it up both, you will just get blurred photo.(The bad example, Java's config...)
