Re: Maco ISO.........?

[Robert Jander <rjander@xxxxx>]

Mark,

I rated the film (maco IR 820 rollfilm) as ISO100 and measured through the lens
without the filter. Then I added 3 stops and shot the photo with an R72 filter.
XTOL 1:3 is too much diluted, 1:1 at 12 minutes worked great for me. You may have
a look of the results at www.photopoint.com (user=rjander@xxxxx). There you will
also find pictures shot with Nikon Coolpix 950. You might find that he picture
quality on the albums is so so, but somehow they appeared much darker after I
transfered them to the album, but you'll get an idea.

Regards

Robert
