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.
And all this is just what Tracking does for the deconvolution module.
For your convenience, the NBAccent module will, by default, use the same Region of Interest that was specified during AutoDev.
The 'Intricacy' parameter controls how much smaller scale detail should prevail over larger scale detail.
The Stereo 3D module is able to export your images for use with Facebook's 3D photo feature.
To only brighten the image (for example if you wish to bring out faint H-alpha, but nothing else), set this parameter to 0%/ 100%.
You can convert everything you see to a format you find convenient. Give it a try!
