    sure, send me an email. But I’d like to know what is not working with you, because maybe I didn’t explain something very well too.
    Is there a part you didn’t understood ?

    Hello Francois, thank you for the filters and tutorials.

    I have followed your instructions and can’t get the compiler to convert the prefilter.c to an exe file.

    Do you think you could email me a copy of the prefilter.exe file, as I am very interested in using your process to do some lighting in AE.

    thanks, P Debay
