Re: metering landscapes (spot / incident)

2001-12-25 Thread Frantisek Vlcek

Thanks to all. I really would like to take my Pentax V spotmeter
along, but it's s big and heavy and won't fit in a pocket. Perhaps
if somebody sells me an Pentax Digital Spotmeter ;-))) ?

I am IMHO proficient in the use of spotmeter (although it's not colour
calibrated by Zone IV or other source), but for BW film, I wouldn't
take any meter at all and trust my mind (as it's most fun, and now
with experience works quite well). But I will be shooting chromes, and
there I thought a meter would be better.

Anyway, I will use the 6 degree spotmeter built-in in my rangefinder
camera to guess and fine the exposure, and maybe use the
reflective mode of the incident meter.

2) question - you all told me to use dome and point it AT camera. But
that's for faces and such things, but landscapes are flat - there is
not light from underneath like in 3D objects like faces - so wouldn't
it be better to use the flat diffuser or dome but parallel to the
landscape?

'3) Perhaps I will just take the spotmeter and cope withj the bulk :)
Yes, I probably will. but out of curiosity, what about above #2 ?

thanks a lot

You're correct that the light in a typical landscape isn't coming from
underneath the scene or from the camera position, But that doesn't mean
you shouldn'tmeasure the light that's coming from behind the camera.
In most photographs, the planes that are revealed to the camera comprise
the majorit of the frame. So, yes, in that case, use the incident meter
and point it at the camera. The sufaces that are facing the lens will be
properly exposed. If, on the other hand, 'you are concerned about the
exposure value orf a surface that is facing the sky, you'd want to use
your spotmeter. Consider, for example, a snowfield that reflects a
bright, sunlit sky. The light coming from the direction of the lens
might  be insiginificant in comparison to the light that is illuminating
the snowfiield from above. In that case, you'd want to measure the value
of the snow with a spotmeter, consider that you'want your exposure two
stops brighter than medium gray, and expose the film two stops more than
the spotmeter reading on the snow field.
 I understand your reluctance in dealing with the bulk of the
Spotmeter V. I own one as well. And I take it when I know I'm going to be
dealing with a difficult lighting situation. For flat, behind the cam,era
lighting of most scenes you'll do fine with the incident meter. However,
you should take the Spotmeter V  with you and satisfy your own curiosity.
I think you'll find that when shooting an evenly lighted scene, you'll be
able to point the spotmeter at a moderately reflective object ( a medium
green, light brown,, medium red, or a grey) amd get a reading identical
to that of the incident meter. However, in other situations, the
difference between a properly obtained spotmeter reading and the incident
meter reading could be several f stops.

Well, why not?
 
1) should I use the dome diffuser? Or the flat diffuser?

1) I'd use the dome diffuser.

2) how should I point the meter? parallel with ground? Half
point
between sun and camera (as in studio) ?

2) the meter should be set in a way to read the light as it goes
on the subject. Point it to receive the light like the part of
the subject you want to meter does.

3) Anything else?

3) Nothing that I can think of at the moment...

I think that incident meters work very well for lancscape photography, since you 
usually have a
range of values in the scene. The exceptions would be if you're shooting white sand 
and water or
black volcabnic rock.. In those cases, you would want to use a spotmeter and 
deetermine the
values of the significant parts of the scene.

Weather is gonna be overcast probably, so what about just using

2001-12-24 Thread Shel Belinkoff

*Sometimes* an incident meter will work well for landscapes.  There are
too many variables to make such a blanket statement.  If the contrast
range of the scene is too great for the film, you'll never know it by
using an incident meter.  Nor can you get an accurate reading if you're
standing in a light that's different than that of the subject.  Only a
spot meter will be able to provide accurate readings in such situations.

Hi Shel,
When I use an incident meter, it's a given that I position the mteter in
the same light that is striking the subject. It's basically the same as
using a grey card at the subject. It gives you a midpoint exposure, and if
most of your values fall to one side or the other of a grey value, you'll
be pretty darn close to a perfect exposure.

Re: metering landscapes (spot / incident)

2001-12-24 Thread Shel Belinkoff

Hi Paul ...

To me it's not a given, as it seems that with landscapes there's often
something in the distance that's part of the scene.  And with landscapes
there are times when parts of a scene are in deep shadow or in bright
light.  Perhaps I am pickier than most, but I want to know exactly what
the range of light is in a scene so that I, not an averaging meter, can
choose where the highlights and shadows will fall.

You are right, however, that when photographing an average scene, and
you are reading the same light that's falling on the subject, an
incident meter will give good results.  However, once you stray from
average, or are photographing a scene that is not in the same light the
meter reads, the incident meter is best replaced with a spot meter.

How would you use an incident meter to photograph a scene when you're a
great distance from the area you want to capture, say a distant mountain
range across a wide valley?  In a situation like that, IMO, only a spot
meter or a TTL meter can be truly dependable.  And if your camera
doesn't happen to have TTL metering, as is the case with many MF and LF
cameras, what then are your options?

dark valley below them to trust the LX's meter. However, I used the spot meter

Re: metering landscapes (spot / incident)

2001-12-24 Thread Tom Rittenhouse

Well now, if I was across the valley from what I was photographing and it
was in direct sunlight I would hold my incident meter in direct sunlight
between my camera and the scene with the meter pointed at the camera. If it
was in shadow I would hold the meter in shadow and follow the exact same
procedure as above. But, you say, what if the scene is in direct sun and
there is a cloud or something preventing me from getting a direct sun
reading, I need a spot meter for that don't I? Nope, just close down a
couple of stops from the meter reading and shoot away. The thing is, with a
little experience, you have a good idea of the adjustment needed in just
about any situation. The incident meter gives you the baseline exposure and
experience gives you the proper adjustment.

The standard way to use an incident meter, for the benefit of the original
poster, is to use the dome, hold the meter at the subject, point it at the
camera, and take your reading. The disk is used for light balancing readings
which are usually only used with artificial lighting though they can
sometimes be useful in other situations. The incident meter used with the
dome, as mentioned above, gives you the equivalent of a gray card reading
without the fuss and bother. Experience tells you how to compensate for
different tones, etc.

In fact, unless you are doing custom processing of your film to rigorous
standards, ala zone system, the incident meter will give you just as
accurate an exposure as a spot meter. Better, if you are not extremely
skilled with that spot meter.

Well, Paul, the exact same sun was shining on that mountain as was shining
on you. Is that not correct? And an incident meter would have given you the
correct reading for the sunlight shining on you. Is that not correct? Yes,
in such a situation, the only type of reflected light meter that would work
well is a narrow spot meter. But, I submit, you could have gotten just as
accurate a reading from an incident meter without 1/10th the hassle.

Dome, pointed at the camera from the subject. No compensation is normally
needed in such a situation as hte meter is reading the light rather than the

No, it wasn't. I was shaded by the peak of Mammoth Mountain. The Minaret's were
getting the rising sun. And I was trying to get a moonlight effect, so I was
using the spotmeter to put the sunlit portions of the Minaret range in zone 4
or thereabouts.
   My point is that I had an application here where the spotmeter was very
valuable. But I agree that the incident meter is a good tool for almost all
situations. But there are a few exceptions. As Shel noted, one exception is
where the subject's lighting is different thatn what you can reasonably measure
from camera position. I'm sure you agree with this.
