vkdt is a graph-based photography workflow toolbox.
vkdt is designed with high performance in mind. it features a flexible processing node graph at its core, enabling real-time support for animations, timelapses, raw video, and heavy lifting algorithms like image alignment and better highlight inpainting. this is made possible by faster processing, allowing more complex operations.
This is free and open source software.
Key Features
- Very fast GPU only processing.
- General DAG of processing operations, featuring multiple inputs and outputs and feedback connectors for animation/iteration.
- Full window colour management.
- Noise profiling – standard noise reduction is performed by the default denoise module. it makes use of a noise model to use as a prior for the expected amount of noise in the image, depending on iso value.
- Minimally invasive folder-based image database:
- it does not copy around your original data.
- it does not write to your original data.
- it merely writes *.cfg sidecar files with processing info.
- in fact these are the actual input files to a loaded directory. there is, however, a fallback to known raw files which will spawn default .cfg files by simply appending the suffix to the full name.
- it writes a minimal vkdt.db file to each directory, containing
- information about rating and labels.
- Command line utility.
- Real time magic lantern raw video (mlv) processing.
- 10-bit display output.
- Gamepad input inherited from imgui.
- Automatic parameter optimisation, for instance to fit vignetting.
- Heavy handed processing at almost realistic speeds.
