Sharpen RAW files before HDR processing?

[Honu]

I convert my photos to TIFF in DPP and then use the TIFFs for HDR processing in Photomatix. Should I sharpen the raw files before I do this?

Thanks!

no, photomatix could very well cause the sharpening to exadgerate leaving white specks in the photo. This does not always happen but it has happened to me with enough frequency I found that it's better to sharpen the post photomatix image in Photoshop.
