（Photoshop外掛程式）Hydra JPG Degrader 1.1

Hydra JPG Degrader是一個Photoshop外掛程式，增加了JPG壓縮，噪聲和色差到圖像。這個外掛程式有助於大大加快合成一個CG編譯到現有的JPG背景的過程。通常的CG效果圖和清潔相比看起來太鋒利， JPG背景，你需要巧妙地降低了重心呈現以符合您所合成成背景的外觀。目前做到這一點的唯一方法是儲存了一層具有較強的JPG壓縮的部分，然後重新匯入該層和屏蔽掉了CG編譯層以外的區功能變數。這是一個繁瑣的過程，最好的你能做的就是猜測在什麼水平JPG壓縮的需要相符合的背景。它可以讓你看到合成在你的其他層上方新增圖層為你實時看到壓縮的新增到得到一個完美的過渡量。除了JPG壓縮這個外掛程式也可以讓你的廣告噪音和色差，這是你在拍攝照片時可能會發生微妙的色調偏移。

對外掛程式的技術方面也有2微調滑塊的水平和垂直階段。在圖像的JPG壓縮在一個網格佈局建立的。通過調整你的新層的水平和垂直階段，你可以在此格巧妙地左右搬移，以配合您嘗試符合背景所用的網格。這個外掛程式還利用對外掛程式的一個新的Adobe的SDK功能，容許更好的處理層。有了這個外掛程式，你現在能看到你文件中的所有其它可見圖層的上方目的層組成。這是非常有用的，當你嘗試在目的層的JPG壓縮符合層的現有組成。

Hydra JPG Degrader is a photoshop plugin that adds JPG compression, noise and chromatic aberration to an image. This plugin helps dramatically speed up the process of compositing a CG rendering into an existing jpg background. Typically CG renderings look too sharp and clean compared to a jpg background, you need to subtly degrade the CG rendering to match the look of the background you are compositing it into. Currently the only way to do this is to save off part of a layer with strong jpg compression and then reimport that layer and mask off the areas outside of the CG rendering layer. This is a tedious process and the best you can do is guess at what level of jpg compression you need to match the background. Hydra JPG Degrader lets you see the new layer composited on top of your other layers as you see in realtime the amount of compression you are adding to get a flawless transition. In addition to jpg compression this plugin also lets you ad noise and chromatic aberration, which is the subtle hue shifting that can occur when you are taking a photograph.

On the technical side of the plugin there are also 2 fine tuning sliders for horizontal and vertical phase. Jpg compression in an image is created on a grid layout. By adjusting the horizontal and vertical phase of your new layer you can subtly shift this grid around to match the grid used in the background you are trying to match. This plugin also utilizes a new Adobe SDK feature for plugins that allows better handling of layers. With this plugin you are now able to see your target layer composed on top of all other visible layers of your document. This is extremely useful when you are trying to match the jpg compression of your target layer to an existing composition of layers.

Hydra JPG Degrader is compatible with the following versions of Photoshop.
Windows XP, Vista, Windows 7, Windows 8 and above 32 + 64 bit CS3, CS4, CS5, CS5.1, CS6, and CC
