The Stereo 3D module is able to export your images for use with Facebook's 3D photo feature.
The 'Facebook' button in the module saves your image as dual JPEGs; one image that ends in '.jpg' and one image that ends in '_depth.jpg' Uploading these images as photos at the same time will see Facebook detect and use the two images to generate a 3D photo.
Please note that due Facebook's algorithm being designed for terrestrial photography, the 3D reconstruction may be a bit odd in places with artifacts appearing and stars detaching from their halos. Nevertheless the result can look quite pleasing when simply browsing past the image in a Facebook feed.
Whatever detail lies outside the RoI, is simply forced to conform to the stretch that was designed for the RoI.
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%.
It governs the range of detail sizes HDR should concentrate on, in order to bring out the most detail.
The HDR (High Dynamic Range) module optimises local dynamic range, in order to bring out the maximum amount of detail that is hidden in your data.
The Heal module was created to provide a means of substituting unwanted pixels in an neutral way.
You can convert everything you see to a format you find convenient. Give it a try!
