HDR Effects (SuperBeasts.AI)

The HDR Effects is an image processing application that enhances the dynamic range and visual appeal of input images. It provides a set of adjustable parameters to fine-tune the HDR effect according to user preferences.

Features

  • Adjusts the intensity of shadows, highlights, and overall HDR effect
  • Applies gamma correction to control the overall brightness and contrast
  • Enhances contrast and color saturation for more vibrant results
  • Preserves color accuracy by processing the image in the LAB color space
  • Utilizes luminance-based masks for targeted adjustments
  • Blends the adjusted luminance with the original luminance for a balanced effect

Parameter details

The application provides the following adjustable parameters:

  • hdr_intensity (default: 0.5, range: 0.0 to 5.0, step: 0.01):

    • Controls the overall intensity of the HDR effect
    • Higher values result in a more pronounced HDR effect
  • shadow_intensity (default: 0.25, range: 0.0 to 1.0, step: 0.01):

    • Adjusts the intensity of shadows in the image
    • Higher values darken the shadows and increase contrast
  • highlight_intensity (default: 0.75, range: 0.0 to 1.0, step: 0.01):

    • Adjusts the intensity of highlights in the image
    • Higher values brighten the highlights and increase contrast
  • gamma_intensity (default: 0.25, range: 0.0 to 1.0, step: 0.01):

    • Controls the gamma correction applied to the image
    • Higher values increase the overall brightness and contrast
  • contrast (default: 0.1, range: 0.0 to 1.0, step: 0.01):

    • Enhances the contrast of the image
    • Higher values result in more pronounced contrast
  • enhance_color (default: 0.25, range: 0.0 to 1.0, step: 0.01):

    • Enhances the color saturation of the image
    • Higher values result in more vibrant colors
