<p class="MsoNormal"]Ok, let me give an example of what I would be wanting to do,
explain how my camera settings and a filter would accomplish that&hellip; and see if I
know what I&rsquo;m talking about. This isn&rsquo;t the exact scenario I ran into, but it
draws a more clear picture (heh, no pun intended).<o></o>
<p class="MsoNormal"]If want to take a picture of, say, a baseball player up to
bat and I want to have the batter in focus, the background blurred, and catch
the &lsquo;motion&rsquo; of the bat swing (i.e. the bat itself would be blurred, hopefully
without blurring the batter much), then I&rsquo;d want to set a fast aperture (say,
2.8) but have the shutter remain open long enough to catch the blur. Now, if
the shutter stays open too long I overexpose, so I want to darken things&hellip; this
is where a darker filter comes in (Neutral Density 1.8? 6 stop equivalent). It
darkens the target shot, allowing me to use a 2.8 f/stop, thereby blurring the
background, yet keeps the lens open long enough to catch some blur without
overexposing. (I know ISO will probably play a part too, but I think it isn&rsquo;t
the main factor and I would want to keep it low for quality purposes
anyhow?).<o></o>
<p class="MsoNormal"]<o></o>So, do I have all that correct?<o></o>
<p class="MsoNormal"]<o></o>Main reason for asking is I now have (what I believe will be)
my &lsquo;walk-around&rsquo; set of lenses being (all Canon&rsquo;s) an EF-S 10-22, EF 24-105 4.0
L IS USM, and EF 70-200 2.8 L IS USM, all use 77mm filters. I&rsquo;ve got (all
B+W&rsquo;s) a Slim Polarizer for the 10-22, and also have a good
(Kaeseman/MRC/X-Pro/etc) Polarizer, UV/Haze filter, and 8-Star effect filter.
I&rsquo;m looking at picking up one of the neutral density filters to complete the
basic &lsquo;set&rsquo; of filters I might find useful with all these.
