The Synth module generates physically correct diffraction and diffusion of point lights (such as stars) in your image, based on a virtual telescope model.
Besides correcting and enhancing the appearance of point lights (such as stars), the Synth module may even be 'abused' for aesthetic purposes to endow stars with diffraction spikes where they originally had none.
Any other tools on the market today simply approximate the visual likeness of such star spikes and 'paint' them on. However the Synth module can physically model and emulate most real optical systems and configurations to obtain a desired result.
Thank you StarTools for turning my average photos into amazing ones.
StarTools keeps a detailed log of what modules and parameters you used.
As of StarTools 1.6, you get the choice of two noise reduction styles.
The two aspects - color and luminance - of your image are neatly separated thanks to StarTools' signal evolution Tracking engine.
The Stereo 3D module can be used to synthesise depth information based on astronomical image feature characteristics.
You can convert everything you see to a format you find convenient. Give it a try!
