Hello, Still thanks for having made me discover the HDR. Thanks to Photomatix much of my contrasted photographs would have been lost, others return a good more beautiful effect in HDR. Some are visible on my blog: ???Un peu de tout"(A Little bit of all). What is a pity it is the slowness of the program but as I will acquire very last Mac that should arrange the problem. It is with people like you, who share their experiment, that amateurs as me can progress. So long on your blog, Frank
