Hello All, Writing in for a friend- he runs PS Elements 8 on a Mac laptop. He wants to delve into HDR. We're both soon taking a one-day class on using Nik HDR Efex Pro. At first blush it looks like Nik says this program will not work with Elements, Elements topping out at 16-bit capability where HDR Efex Pro needs 32 or 64-bit capability. That said, in searching for answers I've seen references, without there being any further information, that Nik HDR Efex Pro can be used as a stand-alone program. Does anyone do this? Can anyone confirm that this Nik program can be used as a full HDR workflow solution completely independent of a Photoshop program? And I mean the full workflow- from merging the separate photos to telling it to print the HDR results and saving as tiffs or jpegs, all separate from Elements or any other editing program. Thanks for your help, I sure appreciate it.
