Film Emulation Nodes v1.4.3

一套定制的节点组，旨在Blender合成器中模拟“胶片质感”。

1.3.0版本包含以下节点：

光晕 - 在明亮光源周围添加光晕效果，模拟电影素材中常见的光晕。

暗角 - 应用暗角效果，使图像边缘变暗或着色。

焦点暗角 - 使图像边缘区域虚化，模拟浅景深，并可选择添加叠加层以可视化衰减渐变。

程序化胶片颗粒 - 为图像添加程序生成的胶片颗粒。

电影胶片颗粒 - 为图像应用真实的胶片颗粒纹理。

镜头污垢 - 模拟相机镜头上的污垢、灰尘或污渍效果。

胶片边框 - 在图像周围添加边框，模拟扫描胶片的效果。

白色胶片斑点 - 为图像添加白色斑点和斑点，模拟老旧胶片中的瑕疵。

色彩密度 - 允许您调整图像中特定颜色或色谱的密度。它提供多种微调选项，并且可以组合使用以同时修改多种颜色。

胶片色调 - 将互补色应用于图像的阴影和高光部分，并可选择添加“漂白”效果，营造褪色效果。

阴影去饱和度 - 降低图像最暗区域的饱和度，创建更干净、更中性的黑色。

黑白 - 一种不同的单色图像风格。

光晕（旧版） - 光晕节点的旧版本。

像素化（旧版） - 将图像像素化（仅适用于 4.2 之前的版本）。

圆形边框 - 为胶片边框节点创建的程序化遮罩。

渲染分辨率 - 读取渲染分辨率（使用驱动程序）以优化大多数节点的纹理缩放。

每个节点都带有多种可调节参数。以下将详细介绍这些调节参数。

A package of custom-made node groups made to emulate the 'film look' inside of Blender's Compositor.

Version 1.3.0 includes these nodes: 

Halation - Adds a glowing halo effect around bright light sources, simulating the characteristic halation seen in film footage.

Vignette - Applies a vignette effect, darkening or coloring the edges of the image.

Focus Vignette - Defocuses the outer regions of the image, simulating a shallow depth of field, with an optional overlay to visualize the falloff gradient.

Procedural Film Grain - Adds procedurally generated film grain to the image.

Movie Film Grain - Applies real film grain textures to the image.

Lens Dirt - Simulates the effect of dirt, dust, or smudges on a camera lens.

Film Frame - Adds a border around the image, replicating the look of scanned film rolls.

White Film Speckles - Adds white specks and spots to the image, mimicking imperfections in old film footage.

Color density - Allows you to adjust the density of specific colors or color spectrums in your image. It offers multiple options for fine-tuning and can be used in an array to modify several colors simultaneously.

Film Tint - Applies complementary colors to the shadows and highlights of an image, with an option to add a 'bleach look' effect for a washed-out appearance.

Shadow Desaturate - Reduces the saturation in the darkest areas of the image, creating cleaner, more neutral blacks.

Black & White - A different style of a monochromatic image.

Halation Legacy - An older version of the halation node

Pixelate Legacy - Pixelates the image (useful only for versions older than 4.2).

Round Frame - Procedural mask created for the Film Frame node.

Render Resolution - Reads the render resolution (using drivers) to optimize texture scaling across the majority of the nodes.

Each node comes with a variety of adjustable parameters. More details on these adjustments are provided below.
