Re: full moon: what went wrong?

Also, the moon is pretty quick moving - so a multi-second exposure
with 250mm lens will surely show just a trail of several moons not a
single ball. With 500mm lens you have to keep your exposures pretty
short (1/30+) or you will get motion-blurred moon too. So it's about
the same with 250mm lens. It can be calculated. Or use a rotating
telescope mount.

Pan the moon? Sounds like a pagan ritual. Do you have to do this in the
nude?

The moon and earth are the same distance (essentially) from the light source
(Sol). The moon is essentially a rock, so shoot at the same settings you
would shoot a city street in bright sun.

Sridhar,

Taking a picture of the moon is taking a picture of a landscape in full sunlight!  You 
need the same time and f-stop as you would use on a sunny day.  (1/100 second at f 11?)

Because most of the framed area is dark, an average metered exposure will try to make 
the night appear as day.  The Moon then is overexposed by many stops.

What you have is a cloud of light around the real Moon, because your lens is not 
prefect and will splash some light near the correct focusing spot.  The moon you see 
above the white cloud of light is an internal reflection of the real moon off of one 
of the internal surfaces of the elements of your lens.

Try a manual setting with a much quicker speed.

Regards,  Bob S.

 Im confused - which is the moon? the question arises
 as the bright intense image wasnt there in reality.
 Is the moon is in the center of the bright image. 
 then how come the 'ghost' image of the moon above it ??
 
 I used a Tokina 50-250 at f4 and this was a multi-second 
 exposure (sorry not sure how long).
 shorter exposures were not print-worthy (!).
 
 whats wrong and what should I be doing next time?
 thanks in advance.

Re: full moon: what went wrong?

2002-07-12 Thread Jim Apilado

I like to photograph full moons for later double exposures with some urban
evening sights around Portland, OR.  I use a 200mm SMC Takumar,  Velvia 50
slide film, and, of course a tripod.  The 200mm doesn't give me a full frame
image but one that approximates a full moon in the sky a few hours after
moonrise.  My exposure is like shooting in bright daylight: 1/250 at f 8.
This recommendation came from an article in a photo magazine and it works.
Good luck,

Jim A.
