raw2film 0.7.1

RAW image editor that emulates the look of various film stocks.

Raw2Film

Raw2Film is full raw image editor with a focus on realistic film emulation.

The looks are based on published film datasheets and use the image processing pipeline from Spectral Film LUT.

The film emulation includes:

• Both negative and print material emulation for a huge variety of emulsions.
• Grain with varying intensity based on brightness and hue.
• Halation to add natural glow to highlights (no data available, so intensity should be adjusted to taste).
• Resolution and micro-contrast matches mtf chart for each film stock.
• Set the simulated frame size to match resolution, grain intensity, and aspect ratio.
