Walter & Group :
From Troy Miller:
Wow, what a
well-described approach Molly offered! Thanks Molly – all great ideas
there. Your description of having ONE instructor as lead and coordinating
the others as assistant coaches is key. Yes, it requires discipline and
ego suppression from some of the instructors (who may be as highly-qualified or
more than the chosen lead) -- but for the student on the receiving end, it will
come across as a much more coherent bundle of digestible information. I’ve
participated in this type of format many times, both as lead and as
helper. And I believe that the approach is sound, as evidenced by the
universal improvements shown by students. It rarely leads to confusion
because all students hear the same material at the start (assuming it’s correct
info, presented logically). Whether rotation of helpers is possible will
depend on how much time is available in the session and how many topics are to
be covered in that time.
I have some advice for
Sam on videotaping. Being able to see clearly depends mainly on
CONTRAST. If you want to see what the rod is doing, then you have to make
it as different from the background as you can. If you want to see what
the line is doing, ditto. After struggling for one winter trying to video
up here (probly 1993 or 4), I discovered that I could really see the flyline in
this one Anchorage School District gymnasium. What was
different about it was that they had a large mural of a dark sky with the
Northern Lights on it. I’m colorblind, but I think it was either a VERY
dark blue or purple (almost black). I had on a Cortland 333 “Strike
Indicator” flyline, which has alternating black and white bands maybe 18 to 24”
long each. When video’d against that backdrop, it was like a strobe
sequence which was the most beautiful and enlightening thing I’d ever
seen. It absolutely re-inspired me and I was off to the races filming
everything I could think of casting-wise. Someone (Lefty, Bill G?) once
described wrapping your rod blank with Teflon tape to make it stand out against
a dark background. Same idea. Contrast, contrast, contrast. I
think shooting something light against a dark background (with LOTS of front
lighting) is easier to see upon playback, than if you have a dark rod/line
against a light background. But that’s just
me…

Advice
from Guy Manning:
you have a Sony camcorder of any model it has what is called
“Sports Mode”. In this mode, though it is still recoding the same number of
frames per second, it is using a much shorter exposure time for each frame. I
believe it is about 1/2000 of a sec. Using this mode will help to stop the line
and rod but will not completely solve the problem. Part of what is happening is
that the line diameter takes up such a small part of the pixel that it may not
be recorded, instead what is behind the line is recorded.
A few things to
try:
1.
Use a Sony
camcorder in Sports Mode, other cameras probably won’t have this
capability
2.
Find a dark
background and shoot against it.
3.
Choose an
oblique angle to the caster so the whole back/fore cast is seen from just off
the casters view.
4.
Buy a
hi-definition video camera (pro-sumer models) with variable shutter speeds, this
is going to be expensive though.

Peter Minnick has a suggestion on where to get
some information on video techniques:
Macauley Lord really has covered this videotaping topic extensively. He
recommends a dark background such as a hedge to better highlite the flyline on
video....I suggest contacting him for more input and references on this
topic....Peter

From Mack Martin on using video technique of
sufficient quality to see the fly line for teaching:-
Gordy:
The question raised
regarding teaching with video and being able to see the fly line has three
primary variables. First is a flat colored background for contrast with the fly
line. This is generally accomplished with trees or foliage (evergreen trees work
year around) that are convenient to the teaching area. If that is not
available then the next best thing is an artificial background that is dark and
will allow the wind to pass through within reason ( 30 MPH wind might be a
problem). A very good material for this is a shade cloth (60% black knit)
available at PAK Unlimited in Cornelia, GA (www.pak-unlimited.com). If you use this
material you will have to string up a length about 100' long and somewhere
between 12 and 16' wide and elevate that to the desired distance above the
ground.
The next variable that
is important is the color and size of the fly line that you are filming. Orange
seems to work best and a line that is 7 wt. or larger makes for good contrast.
Yellow will also work and the SA XXD line also does a good
job.
The last
consideration is camera and video software for analysis and discussion with the
student. The camera must be a digital camera and most digital camera's today
will work, but the best are those with very good light gathering lenses. A good
camera will run about $2000+, but others in the $500 range will
work.
The
software that is needed to assist in the analysis of the casting problems, etc.
must be able to slow down the real time casting so that the hands, arms, loops
and rod can be seen in both casting planes. This software is available for both
PC and Apple computers. Apple software seems to work the best. When the student
can see each action that he makes to cast a fly rod and the resulting loops, he
can quickly understand where the problems lie. This approach works extremely
well with Bruce's 6 step method of analysis.
If there are other
questions regarding this, I will be glad to try to answer those as
well.

Mack... Thanks! I remember well the
time we did that video study to try to challenge the concept of the loop forming
exactly at RSP... Your setup included a dark (black) night, black
background and a carefully designed light system in addition to your rather
sophisticated camera and computer readout system... For a non photo
guy, I was impressed to say the least.

Walter Simberski of our Group has invented and
patented many things. This one is in line with our
discussion:
Gordy,
I really hesitate to use this board to
promoting a product I am going to be selling but in this case I think it
adds
something with respect to using video cameras for
teaching:
I'll let you decide if you want to pass it on to
the group.
Cheers,
Walter

From John Bilotta
:
Regarding Sam’s
questions on video cameras:
You are probably
already doing all this, but:
Think of the background
behind the caster – a darker background provides much better
contrast.
Really try and avoid
shooting upward into daytime sky.
The best light of the
day is usually morning or late afternoons.
If available I
usually try and shoot with a thick row of green trees behind the caster, I’ve
also used a dark two-story wall.
Use a tripod to
steady the picture
Hopefully some of this
helps, in terms of cameras almost all the newer 3 chip cameras deliver a very
high quality picture.

From Ally Gowans:
Hi
Gordy,
For anyone using video
or photography to look at casting there are a few simple
rules.
Make sure that the line
contrasts with the background. A dark background is generally
good.
Use a highly visible
(contrasting) line.
Ensure that the light
is coming mostly from behind the camera to illuminate the
line.
Don’t try to capture
120 ft casts unless conditions for line visibility are perfect because the line
will simply not show up and the caster will look like a
dwarf.
Use as little line as
possible for illustration purposes; it will still look like a huge distance in
the picture. (Check out the famous Rio Line advert where the angler with a
double handed rod appears to be casting and enormous amount of line by dividing
the rod length into the line length).
For video you want as
much light as possible and as fast a shutter speed as possible. Normal video
frame rate is insufficient for high speed action; you need to have a much higher
rate of frames per second for detailed analysis.
For photographs very
high shutter speeds can reveal instances when the line position is
unbelievable!
Video may be helpful
for explaining to students.
Good instructors often
diagnose faults at 100 yards and sometimes instructors lacking experience stand
too close to their students and only get part of the picture. So “stand back in
amazement”.
Best
wishes,
Ally

Thoughtful
messages from Michael Jones:
To reply to this thread, I have two immediate
observations for the postings listed:
For Molly: We are finding that 'feeling the cast' is as important as
anything to reach the 'breakthrough point' for the student. Do not be
afraid to say less, give direct instruction, and have new students cast with
rods that are 'loaded' with heavier lines to augment the 'feel'.
For Jim Laing:
Video cameras are proving to be instrumental tools in teaching casting, but
only when used appropriately; by this, we mean: HIGH CONTRAST of line to
backdrop, be it orange or white, against a dark backdrop. I have seen
excellent video analysis shot with pine trees setting a dark backdrop behind the
caster. Also, consider light conditions and light direction, so that the
prevailing light is illuminating the line/rod/caster to emphasize contrast, and
therefor: the cast. Having a remote control of the camera is also really
helpful, as it allows the camera man to review and edit the shot to produce only
the most important shot: 'the mistake made'.
When showing a student a video analysis of their casting, I ask first:
"What do you see?" rather than "This is what I see." This moves dialogue
in a more positive direction, and allows the student to explain what they see,
and helps you to correct/diagnose what is actually happening in a more
meaningful and helpful way to produce immediate change.
