The crop module is an easy-to-use image cropping tool with quick aspect ratio presets and switchable luminance, chrominance and narrowband accent preview modes.
The module was designed to quickly find and eliminate stacking artefacts across luminance, chrominance and narrowband accent data, as well as help with framing your object(s) of interest.
Using the crop module is fairly straightforward. The desired crop is created by clicking and dragging with the mouse the area to retain. Fine-tuning can be accomplished by changing the X1, Y1 and X2, Y2 coordinate pair parameters.
8 quick-access crops are available to quickly achieve one of four popular aspect ratios. The button names ('3:2', '2:3', '16:9', 9:16') denote the aspect ratio, while the double minus ('--') or plus ('++') signs postfix denotes their behaviour;
A 'Color'/'NBAccent' button is available, which functions much like the 'Color'/'NBAccent' button in the Wipe module. Like in the Wipe module, it is only available when Compose mode is engaged (e.g. when luminance, chrominance and/or narrowband accents are being processed separately, yet simultaneously). The button allows you to switch the view between the luminance, chrominance and narrowband accent datasets that are being processed in parallel. The later is useful if, for example, you need to crop stacking artefacts that only exist in the chroma dataset and/or narrowband accent dataset, but not in the luminance dataset. Because chrominance data always remains linear and is never stretched like the luminance dataset, a courtesy (non-permanent) AutoDev is applied, so you can better see what is in the chrominance dataset. Likewise, a courtesy temporary AutoDev is applied to any narrowband accent data for that same purpose.
No nonsense, affordable astro software that just works.
It doesn't stop there however – the Fractal Flux module can use any output from any other module as input for the flux to modulate.
To apply the new colour balance to the whole image, launch the Mask editor once more and click Clear, then click Invert to select the whole image.
The 'Red, Green and Blue Increase/Reduce' parameters are the most important settings in the Color module.
StarTools can also be entirely operated by touchscreen with all controls appropriately sized for finger-touch operation.
You can convert everything you see to a format you find convenient. Give it a try!
