0.7.5-beta

  • Fixed crash when adding image directory to a collection
  • Added new Auto-adjustment feature with reset button
  • New splash screen on launch
  • Added a crash report function that saves crash data in the same directory as RedLight.exe
  • Fixed issue with sliders working in reverse for shadows and highlights
  • Highlights and Shadows now use a more precise piecewise curve method to calculate light and dark areas
  • Changed function of ok button when on watermark tab to bring users back to export options instead of executing the export.
  • Further optimization of the garbage collection in batch image exports
  • Fixed bug with crop not cropping rotated images
  • Further refinement of matching denoising intensity from preview to final export (still needs more work.)
  • Fixed exporting of .Tiff and .BMP not exporting
  • limited the number of export cores to half of the systems total number of cores. This will limit the amount of system memory RedLight uses and keeps the system more responsive overall.
  • Fixed issue where EULA was being blocked by the splash screen
  • -Known issue- Potential for crashes when auto is enabled when using an AMD CPU, working on fix.

0.7.0-beta

  • Fixed issue with app crashing when Full Preview, reset crop and +- zoom buttons where pressed when no images are in a collection
  • Fixed issue with denoising strength being to high and where preview image and exported images were not identical
  • Cancel button on export progress dialog now actually cancels the export process properly
  • Click show thumbnail names is now remembered between sessions
  • Added number of images are in a collection next to collection name
  • Added a console panel
  • Added links to the official documentation, documentation updated up to version 0.6.0-beta

  • Fixed issue with folder name on collection export also including the number of images in the collection
  • Fixed issue with cropping an already cropped image resulted in displaying the wrong region of the photo
  • Fixed issue with resetting cropped image view not returning to fill preview area
  • A known issue is that zooming in with the mouse wheel is still a bit clunky, it still needs some smoothing.

0.6.0-beta

  • Watermarking tab in export dialog window, allows for custom text font and text tiling
  • Fixed zoom level unzooming when adjustments are applied
  • Fixed brightness, Exposure, Saturation not using the whole range of their respective sliders

  • thumbnails no longer load to memory from scratch every time a collection is selected. Now it creates a image cache folder where thumbnails are stored loading from the disk. Instead of reprocessing thumbnails is a lot faster (once generated).
  • on image or collection export the app is able to use more system processing cores allowing for faster export times

0.4.0-alpha

  • added a clarity adjustment which boosts local contrast and makes textures more pronounced.
  • Improved the contrast adjustment to a advanced local contrast using CLAHE.
  • added per image or multi image rotation. This is persistent and saves image orientation.
  • close option now in the file menu
  • reworked the export dialog window, there is now an advanced tab keeping the main export window easier to navigate
  • added support for custom image resolutions on export
  • optimized garbage collection, memory management and reworked how certain parts of the app use multithreading.

  • Optimized Thumbnail Loading.
  • Improved Memory Management When Switching Collections
  • Modified the collection-switching logic to explicitly delete and reinitialize caches (for full‑resolution images, previews, and thumbnails).
  • Forced garbage collection to help release memory previously occupied by large collections.

  • Enhanced the cancellation logic for worker threads (including export, preview, and thumbnail workers) so that outdated tasks are stopped promptly without blocking the UI.

0.3.0-alpha

  • Addition of photo metadata

First pass at adding metadata to exported photos. In the export dialog there are a few options to add Author or to add a comment. So far it seems to only work on exported .jpg images ill look into this for later releases.

  • Prefix – Suffix

Included the option in the export dialog to include prefix or suffix to the names of your exported images.

  • Adjustment panel sliders

The handles for the adjustments are now defaulted to be in the center of the slider. Moving the handle left will go into the negative and moving it to the right to the positive.

  • Native resolution of image
  • Now on the bottom bar beside the image name it shows the resolution of the original image.
  • Choosing color spaces on export

This is basic first pass on mimicking the Adobe color spaces. Will implement a more advanced version of this in the future.

Patch 0.2.1-Alpha

Fixed issue with not being able to create new collections.

Release 0.2.0-Alpha

Early implementation of new image adjustments. These all apply in the same way as the existing adjustments, either a selection or to the whole collection.

New Adjustments

  • Exposure
  • Highlights
  • Shadows
  • Temperature
  • Vibrance

Image Rotation

Apply this like any other adjustment, select the images or whole collections that need rotating. Operates on a slider drag to desired position or enter number in degrees.

Move images between collections

When right-clicking on a thumbnail, there is a new menu for moving an image or multiple images to another collection. This is useful for collection organization.
