# Line 157 | Line 157 | how to adjust the exposure for each frame.
157   As in
158   .I pfilt,
159   the exposure setting may be given either as a multiplier or as a
160 < number of f-stop adjustments (eg. +2 or -1.5).
160 > number of f\-stop adjustments (eg. +2 or \-1.5).
161   Alternatively, a file name may be given, which
162   .I ranimate
163   will interpret as having one exposure value per line per frame,
# Line 180 | Line 180 | options of rpict, along with appropriate suffixes,
180   and thus should contain a
181   .I printf(3)
182   style integer field to distinguish one frame number from another.
183 < The final frames will use this name with a ".pic" suffix.
183 > The final frames will use this name with a ".hdr" suffix.
184   The default value is the assigned
185   .I DIRECTORY
186   followed by "/frame%03d".
# Line 292 | Line 292 | command, except that the
292   option will always be used to specify an alternate user name rather than the
293   .I "user@host"
294   convention.
295 < Th
295 > The
296   .I -l
297   option may or may not appear, but the
298   .I -n
# Line 362 | Line 362 | used otherwise.
362   The default fraction is 0, meaning no motion blurring.
363   This option does not currently work with the
364   .I ANIMATE
365 < variable, since pinterp only works for static environments.
365 > variable.
366   .TP
367   .BR DBLUR
368   This variable specifies the aperture diameter for depth-of-field blurring,
# Line 384 | Line 384 | world coordinate units.
384   For example, if you wish to simulate a 50mm lens at f/2.0 in
385   a scene modeled in meters, then you divide 50mm by 2.0 to get 25mm,
386   which corresponds to an effective aperture of 0.025 meters.
387 + The focus distance is determined by the length of the view directon vector.
388   The default aperture is 0, meaning no depth-of-field blurring.
388 – This option does not currently work with the
389 – .I ANIMATE
390 – variable, since pinterp only works for static environments.
389   .TP
390   .BR RTRACE
391   This boolean variable tells
# Line 489 | Line 487 | If we only want to see what default values
487   would use without actually executing anything, we can invoke it
488   thus:
489   .IP "" .2i
490 < ranimate -n -e sample.ran
490 > ranimate \-n \-e sample.ran
491   .PP
492   This will print the variables we have given as well as default
493   values
# Line 520 | Line 518 | INTERP= 3                              # render every fourth frame
518   RES= 1024                               # shoot for 1024x resolution
519   MBLUR= .25                              # apply camera motion blur
520   EXP= anim1.exp                          # adjust exposure according to file
521 < pfilt= -r .9                            # use Gaussian filtering
