CARLOVES  SilverFast HDR Studio is phenomenal. I upgraded free to the latest version for my SilverFast Archive Suite for my Canon 8600F. Now I can use SilverFast Multi-Exposure together with the dust and scratch information of my slides in the new 64 bit HDR file.

HDR Studio is opening the 64 bit file without problems and allows me to access the iSRD infrared information, so I can work on my ideal digital negative.

This seems to me like a real break-through for archiving all my slides and negative with the max dynamic range and now with the infrared dust and scratch information as well.

Well done SilverFast!!! Especially with difficult Kodachrome, I can work in HDR Studio comfortably, so to prevent image artifacts, when applying the dust and scratch removal!
