    Hi Kirk,

    Thank you for the links.   I will try it out.

    There is also one other photographic image processing technique that I am really hot to get into.  Schlieren Imaging.

    It is widely used in the aerospace community for photographing shockwaves, thermal convection, turbulence, density gradients and other fluid phenomena. It can be used as a powerful engineering tool and it can reveal some very interesting fluid dynamic effects.

    I have a need to use Schlieren photagraphy/imaging.   So I have been doing a lot of research into the subject to learn how to do it.

    Until recently Schlieren photography has been performed by using an elaborate system of (expensive) parabolic mirrors, incoherent pinpoint light sources and optical filters.

    This link is an examples of the old style setup with a parabolic mirror:

    Then in 1997 a NASA scientist found Schlieren photagraphy can be performed without mirrors via sophisticated image processing.  This led to the current state of the art:

    Then even more recently it has been found that crude Schlieren imaging can be obtained with a regular camera and image processing in Photoshop.  By overlaying two (or more) layers, subtracting their differences, then isolating and highlighting these differences, the effect can be seen.

    The differences between the layers is extremely subtle, going down to singular pixels and not visible with the naked eye.  However it is well within the reach of image processing technology. 

    Isolation of layer differences seems like it could be very much in line with the AI image processing Skylum is already doing.

    Can Skylum image processing be used to create Schlieren images?   

    If yes, it would be extremely helpful if it was part of Luminar 4.  I'll sign up just for that alone.

    Such a capability would be highly desired by a wide range of engineers and likely even experimental photographers if the image quality was sufficient.

    Thank you,



    PS - Any part of Luminar 4 that could be extended to video processing would also be highly desirable.

    Hi Tony,

    Thank you for explanations and elaborating this topic. 

    You can try to edit Schlieren photos in Luminar on your own in the trial mode first.
