Sample 30 is the same as sample 11 (plaster square)
only it will be taken at larger magnification. 
Normally the samples are imaged
with the zoom setting at 1 tick above 60.
Maximum zoom (90) did not seem like a large enough
scale difference... So this set of images will
be taken with the camera position radius decreased
by 8 inches. The tripod position is rather crude,
with floor markings and a paper template.
The zoom is then set to maximum (90)

settiing aperture to same as sample 11 (i.e. same as the
plaster square taken at smaller zoom), which was 
between 11 and 16.
z=353 p = 18 l = 168
after photometer measurements (taken at 8 inches closer
I decided to move the camera to 12 inces closer instead
of 8. and changed robot parameters to
z=345 p = 18 l = 168

At position 1, the camera couldn't be aligned with template 
(that was displaced 12 inches from normal position)
because of lamp holder. Made adjustments in orientation
of camera to try to compensate. This problem will be tru of
all the zoomed samples

Noticed that height isn't very good, The z parameter was good
for position 1 but quite bad for
position 7. Didn't adjust height with slips of paper the
way we did in the normal zoom samples.

4PM finished sample 30. realized I forgot number 29,
so the sequence will be out of order, i.e. sample 29 is taken 
next.
