RapidRAW 1.4.8

Live Previews

Editing in RapidRAW is now more fluid and responsive than ever. Previously, adjustments were applied only when you stopped dragging a slider. Now, you can see your changes happen in near real-time as you drag, providing instant visual feedback.

This was made possible by a large rewrite of the GPU processing engine and improvements to the architecture in general. If you prefer the old behavior or are using a less powerful machine, you can disable live previews in the settings.

Updated Collage Maker

The collage maker has been completely overhauled to give you more creative control. Key upgrades include:

• Drag & Drop: No more random mixing! Place your images exactly where you want them.
• Keep Aspect Ratio: A new option to prevent unwanted cropping of your images.
• Zoom & Pan: Finetune the composition within each cell.

LUT Quality Improvement

Previously, applying some LUTs could result in visible banding or posterization artifacts. This has been fixed by implementing tetrahedral interpolation in the shader, which ensures smooth, high quality color transitions even with lower-resolution LUT files.
