It can actually reverse optical blur. If you have a slightly soft image due to lens diffraction, missed focus, or cheap glass, Astra analyzes how the light was scattered and mathematically reconstructs the original sharp edges.

This is an excellent observation. is not as widely known as Photoshop or GIMP, but it has a very specific, powerful niche. Since you asked for an interesting feature, here is the standout one that professionals prize: The "True Detail" Sharpening & Deconvolution Engine While most software (like Lightroom or Topaz) uses unsharp mask (which creates edge halos), Astra Image 3.0 Pro uses advanced deconvolution algorithms (like Richardson-Lucy or its proprietary "Astra AI").

It has a steep learning curve. The default presets are often too aggressive. The magic happens when you manually adjust the Iterations (how many times the math runs) and Damping (noise control).
