Re: Focusing/Best time of day

[Chris Hulme <chris.h@xxxxxxxxxxxx>]

 Hi All

 I'm just starting getting into B+W infra-red and have only recently 
 joined this list so please forgive my 'basics' questions.

 Focusing:

 I've read the FAQs and other articles about adjusting focus to the 
 red index mark.  On my gear (Minolta AF), the index appears at or 
 about f/4.0. If I use, say, an aperture of f/8.0 will I achieve sharp 
 focus without having to adjust the lens?

 Time of day/year:

 Many articles I have read stress the point that B+W infra-red works 
 best when there is plenty of sunlight.  It looks like I've 
 mis-interpreted here because I read it to mean that the middle of the 
 day provides the best results and consequently have been blasting 
 away with my Dynax on the stroke of noon.  After reading one of the 
 other postings, it appears early/late in the day are the best times 
 as there is a higher proportion of IR at these times.

 Would this be the reason why I've not been able to achieve very dark 
 skies (which is the effect I was after) with either Konica or HIE 
 even though I appear to have got the exposure right in one of my 
 bracketed shots?

 All my shots by the way, have been taken through either a 25A or Hoya 
 R72 filter.

 Many thanks in advance for any advice.
