ComfyUI Node: Panavision Lens Effect V2

Panavision Lens Effect V2:

The PanavisionLensV2 node is a sophisticated tool designed to simulate the unique characteristics of Panavision lenses, widely recognized for their cinematic quality. This node enhances your images by incorporating advanced bokeh modeling, multi-layer flares, chromatic effects, and film-like color science, providing a rich and authentic visual experience. By emulating these lens effects, the node allows you to create images with a professional, filmic look, making it an invaluable asset for AI artists seeking to add depth and realism to their work. The node's primary goal is to offer a comprehensive suite of lens effects that can be finely tuned to achieve the desired aesthetic, ensuring that your images stand out with a distinct cinematic flair.

Panavision Lens Effect V2 Input Parameters:

aspect_ratio

The aspect_ratio parameter controls the width-to-height ratio of the lens effect, allowing you to simulate different cinematic formats. It ranges from 1.85 to 2.76, with a default value of 2.39, which is typical for widescreen formats. Adjusting this parameter can significantly impact the composition and framing of your image, making it crucial for achieving the desired cinematic look.

anamorphic_squeeze

The anamorphic_squeeze parameter simulates the horizontal compression characteristic of anamorphic lenses. It ranges from 1.0 to 2.4, with a default value of 2.0. This parameter affects how the image is stretched horizontally, influencing the overall aesthetic and feel of the image, particularly in terms of depth and field of view.

bokeh_intensity

The bokeh_intensity parameter determines the strength of the bokeh effect, which refers to the quality of the out-of-focus areas in an image. It ranges from 0.0 to 1.0, with a default value of 0.5. A higher intensity results in more pronounced bokeh, enhancing the artistic quality of the image by drawing attention to the in-focus subject.

bokeh_threshold

The bokeh_threshold parameter sets the brightness level at which bokeh effects become visible. It ranges from 0.5 to 1.0, with a default value of 0.8. This parameter helps control the visibility of bokeh in different lighting conditions, allowing for subtle or dramatic effects depending on the scene's lighting.

bokeh_elongation

The bokeh_elongation parameter adjusts the shape of the bokeh, simulating the oval-shaped highlights typical of anamorphic lenses. It ranges from 1.0 to 3.0, with a default value of 2.0. This parameter is essential for creating the characteristic look of anamorphic bokeh, adding a unique touch to your images.

bokeh_rotation

The bokeh_rotation parameter allows you to rotate the bokeh effect, ranging from -45.0 to 45.0 degrees, with a default value of 0.0. This rotation can be used to align the bokeh with other elements in the image, providing additional creative control over the final appearance.

primary_flare_intensity

The primary_flare_intensity parameter controls the brightness of the primary lens flare effect, ranging from 0.0 to 1.0, with a default value of 0.4. This parameter is crucial for simulating the light scattering that occurs when bright light sources are present, adding realism and drama to your images.

secondary_flare_intensity

The secondary_flare_intensity parameter adjusts the brightness of secondary lens flares, ranging from 0.0 to 1.0, with a default value of 0.2. Secondary flares add complexity and depth to the lens flare effect, enhancing the overall visual impact.

flare_position_y

The flare_position_y parameter sets the vertical position of the lens flare effect, ranging from -1.0 to 1.0, with a default value of 0.0. This parameter allows you to position the flare within the image, providing flexibility in how the effect interacts with the scene.

flare_stretch

The flare_stretch parameter controls the elongation of the lens flare, ranging from 0.5 to 2.0, with a default value of 1.0. Stretching the flare can create dynamic and visually interesting effects, simulating the way light interacts with the lens elements.

Panavision Lens Effect V2 Output Parameters:

images

The images output parameter provides the processed image(s) with the applied Panavision lens effects. This output is the culmination of all the input parameters working together to create a cinematic and visually appealing result. The images reflect the adjustments made to aspect ratio, bokeh, flares, and other characteristics, offering a final product that embodies the desired filmic quality.

Panavision Lens Effect V2 Usage Tips:

• Experiment with the aspect_ratio and anamorphic_squeeze parameters to achieve different cinematic looks, such as classic widescreen or anamorphic styles.
• Use the bokeh_intensity and bokeh_threshold parameters to enhance the artistic quality of your images, especially in scenes with strong depth of field.
• Adjust the primary_flare_intensity and secondary_flare_intensity to simulate realistic lens flares, adding drama and authenticity to your images.

Panavision Lens Effect V2 Common Errors and Solutions:

"CUDA device not available"

• Explanation: This error occurs when the node attempts to use a CUDA device, but none is available on your system.
• Solution: Ensure that your system has a compatible NVIDIA GPU and that the necessary CUDA drivers are installed. Alternatively, switch to CPU mode if a GPU is not available.

"Invalid parameter value"

• Explanation: This error indicates that one or more input parameters have been set to values outside their allowed ranges.
• Solution: Double-check the parameter values to ensure they fall within the specified minimum and maximum limits. Adjust any values that are out of range.
