Difference Clouds command changes colors partially in cloud-like areas: The filter renders Solid Noise cloud in an automatically created new layer, and sets the layer mode to Difference, then merges this layer over the specified image.

図17.363 「Difference Clouds」 filter options

乱数種

  This option controls the randomness of the filter. The Random seed box lets you manually enter a seed for the randomization algorithm used. A different random seed produces different results.

Levels

  This controls the level of detail in the noise texture. Higher values give a higher level of detail, and the noise seems to be made of spray or small particles, which makes it feel hard. A low value makes it more soft and cloudy.

タイル化可能

  If you check Tileable, you'll get a noise that can be tiled seamlessly in a grid. The left edge will align seamlessly with the right edge, and the top edge will align seamlessly with the bottom edge. Only the generated noise is tileable. The underlying image is not modified to be tileable.

乱れ

  このオプションを有効にしたときの効果はまるで水面に浮かぶ油か煙幕か生体組織かロールシャッハ紋のような見え方をします。

X, Y

  これらのスライダーはノイズ形状の大きさと均整を水平方向 X と垂直方向 Y の値で調整します。 値の範囲は 0.1 から 16.0 までです。
