Lars, if this is a question to me--then yes, I did consider using an ND filter, but no, I can't use one because the lens I'm using is a 4.5mm fisheye lens that doesn't allow the use of filters, AFAIK.
Either way--you'd want to expose (much) longer than a full cycle which is only 1/100 sec. This severely limits the range of exposure times available for the HDR sequence. If I remember correctly, Santiago Torres captured sunny skies in his PhD thesis, and he had to use two identical cameras for this, one of which was fitted with an ND filter. Aligning the two must have been a nightmare. Axel On 20 February 2012 11:13, Lars O.
