Re: RE: Eclair Cameras: Light Meter Issues
Not to cause any grief here but the ACL meter is not a standard reflectance light meter. What it does is tell you when the light has changed. Those who have bothered to read the manual on the ACL know that you have to first read the light of the scene and then set the meter in the ACL to zero set. It then tells you haw many stops the light changes as you pan, zoom, whatever. In my opinion this isnt worth the price of the leds. You cannot set ASA or DIN into this meter and you cannot simply turn it on aim it at something and read the exposure. It is not a light meter as we know it. It is more like a voltage /ohm meter. Whatever that is worth when you are shooting a scene I dont know.

There are, nevertheless, situations when having an internal
would prove invaluable. Let's say you were walking down the
you saw a UFO. I can pretty much assure you that you don't want
taking out your lightmeter and calculating F-Stops at this time--
matter how much more accurate it would be.
One of the great things about the Canon Scoopic and its M and MS
versions were/are the ability for auto iris. Yes, film snobs
world will tell you that you should always be calculating your
with a light meter--but in the real world the built in lightmeter
tons of problems. I remember being able to do long tracking
the M or MS because it could compensate when you moved from an
lightness to darkness instantaneously. How were the seemingly
tracking shots in "Goodfellas," "The Player," and "Snake Eyes"
accomplished? I can't imagine these being done with the operator
manually adjusting the iris. Why do all of the leading video
manufacturers put auto iris onto their cameras--because it makes
shooting much less dicey, gives you less headaches if in the
situation you had taken inaccurate readings and it gives the
inexperienced videographer or filmmaker the ability to make movies
without having to worry about the painstaking process of light
Yes, in some instances manual light readings may make a slightly
exposed picture. But when the pressure is on its often more
put your trust into a filmmaking machine rather than (to quote the
Pistols) "a human machine." In essence, auto irises and built-in
add to the democratization in filmmaking.
While the ACL does not have an automatic lightmeter like the
its built in light meter allows you to determine the light reading
static shot or a shot without much lighting change (although a
would be static shots). In a previous post it was inferred that
reaching up and changing apertures with the Eclair ACL was
futile. In order to change F-Stops while the camera is exposing
you have to adjust the iris poteniometer while the camera's
running (let's say at 24fps). If you calibrate the meter without
camera's shutter moving you will get inaccurate readings (if you
your readings while film is being exposed). If, on the other
take readings before the shutter is moving then you should
meter by adjusting the potentiometer without the shutter in motion
is how I expose film). According to what I understood from a
conversation with Bernie O'Doherty, having red diodes activated
film is running through the camera can lead to flicker problems.
spoken with Bernie about creating an on/off switch for my camera
will allow me to de-activate the light meter after I've taken a
and before I am about to run film through the camera. I wonder if
previous post entitled EXP ON/OFF switch is related to this?
Now that I'm clear on all of this, it leaves me with two
Does the internal light meter go up to ASA 800 or ASA 400?
2) Does anyone have any other suggestions on how to make the
light meter work with Super 16?
Since the Eclair ACL is such a light weight compact camera it only
sense that it should have a built-in light meter. The techs at
were smart enough to realize this for Regular 16. Even if you
the built-in metering, it would be nice to have others understand
am one voice in this community (who may be among others) who does
believe in the built in light meter for the reasons mentioned
For people like me, who believes in automation at a fair price, It
be great to keep the simplicity and democratization of built-in
metering as an option for Super 16 with the ACL.
