Conditions in the mountains there are very different from what I face here
in eastern Canada. Here I live maybe about 100 to 200 feet above sea level,
and the sun is seldom directly overhead, except maybe in the middle of the
day in the summer. There it seems like the sun is always directly overhead.
UV and flare have been a real problem for me in Bolivia in the past. The
worst part is, I didn't know what was causing the problem, and so was
blaming things like airport x-rays and the heat. But I think now one of the
serious problems was UV, even though I have always used a UV or skylight
filter. The sun is very intense, I guess because it is so close to the
equator, and because we are often at altitudes of 9000 to 15,000 feet. If
someone knows how to adequately handle the UV problem in those conditions,
I'd sure appreciate any advice.
Is there any slide film that gives an advantage in those conditions? I've
always used Kodachrome 64 in the past, but am thinking of using something E6
this time, not sure what yet. Again I'm open to suggestions. I like the idea
of slow film to minimize airport x-ray damage, but then there is the problem
of it being daylight only half of the 24 hrs., so something faster is
helpful for the many nighttime and indoor flash photos. Again, everything
down there is in extremes. It is either daylight, or dark, with 2 minute
sunrises and sunsets (well, it seems that way compared to here).
Also in the past, I've never used a hood, and always used a zoom on the
OM's, which resulted in a lot of flare. Ignorance again. That is one reason
I want to take all primes this time.
