FotoSketcher 4.30 Beta 2 is ready for testing - lots of changes

Hi all,

A second beta of FotoSketcher 4.30 is now available, and it is a significant step up from Beta 1. A lot has changed since then, so here is a full rundown of everything that is new in this version.


- New effects: Circles and Triangles

Two new Stylize effects join the mosaic family introduced in Beta 1. Circles and Triangles use the same space-filling algorithm as Mosaic, but with their respective shapes.

- Cartoon outlines

The Cartoon effect now produces a pure outline drawing when the colour intensity slider is set to 0 - no colour fill, just clean line art. This becomes especially useful in combination with the "Do not erase background" option: apply any effect first, then run Cartoon with colour intensity at 0 and "Do not erase background" ticked. The outlines are drawn on top of your existing result, adding crisp contours to any effect in just two steps.

- Built-in LUT library (LookUp Tables)

The LUTs effect now comes with 18 presets built directly into the application. A new "Select LUT…" button appears in the interface whenever the LUTs effect is active, opening a selector window with a live preview of each preset (right-click n the preview to see the original image):

Architecture · Blues · Cinematic · Cinematic saturation · Cyan skies · Film print · Film tone 1 · Film tone 2 · Golden hour · HDR · HDR natural · Kodachrome · Monochrome artistic · Monochrome balanced · Monochrome vintage · Portrait · Rich colors · Vibrant light

You can of course load your own custom .cube files from disk as well.

- Script engine additions

Three new commands are now available in the script editor:

  • ENHANCE - auto-enhances the working image in a single line.
  • LUT_FILE <path> - loads a .cube file from disk for the next LUTs effect step.
  • LUT_EMBEDDED <name> - selects one of the 18 built-in presets by name (case-insensitive, spaces allowed).

- Auto-Enhance (available in the menu or by pressing 'E')

The auto-enhance feature attemps to optimize the source image. The goal is a clean, natural-looking enhancement.

- Full Reset (clean slate, without having to close and re-open FotoSketcher)

A new Full Reset function clears everything back to the application's initial state in one step - working image, history, LUT, script, custom brushes, and all sliders. To trigger it, simply right-click the exit button (the icon which turns red in the icon bar) or press Ctrl+Shift+N.

- UI improvements

  • Thumbnails in the history gallery now show a blue dot to indicate images that have not been modified - making it easier to spot your original source images at a glance.
  • Hovering over any thumbnail now displays a tooltip with the filename and file size, which comes in handy when working with multiple images.
  • Added support for opening .webp images (a format often found on the web).
  • Improved Italian and Korean translations. Big thanks to users Roberto and Jaehyung!

- Bug fixes

  • The window should now correctly re-scale when moved between monitors with different DPI settings.
  • Fixed an issue on macOS Sequoia where the splash screen would reappear on top of the main window after dismissal.
  • When the "Erase background" option is off, the Cartoon effect now correctly blends the pre-effect pixels into the output rather than discarding them.

As always, any feedback - bugs, oddities, anything that does not feel right - is very welcome. Please leave a comment below or send me an email at contact@fotosketcher.com.

Happy testing!
