a high quality 300mm lens)

on-board self-timer
The
Aim:
To photograph the moon.
The relative size of the moon
when photographed with a 300mm lens on digital.
How:
ISO: Use iso100 to
reduce or avoid noise.
Aperture: About F9
does the job, less may create focusing problems, and f16 may make it too
dark (not letting enough light in).
Shutter Speed:
Since the moon is so far away, you need to use a steady tripod with a
speed of 1/125 or
1/160 just to reduce blur.
White Balance: Be
sure your white balance is
set correctly, but I'm still not sure to what. In the mean time, I've found
'daylight' to be fine.
Filters: Not
needed.
Lens: To properly
fill the image area, you'd need a 1,200mm lens
(or a telescope with a camera mount), but since most of us don't even have
a friend who knows someone with such a lens, we have to make do with what
we've got. The 300mm length is a good start.
Issues With Zooming:
Also, if you zoom right in onto any object, then your camera will wobble a
little from any shake in the camera-tripod system, and the mere movement
of the shutter opening does introduce some shake. For this, you can use
the mirror lockup option in your camera's menu (see your instruction
menu). Also, use a remote shutter release or on-board timer, as just
pushing the button will wobble the camera a bit.
The
statistics
To
get this data, I've used the "ExposurePlot Graphics" feature in Wega2. This feature gives a statistical view of what you do. In a
comparison with other photographers, you should get fairly similar
results if you shoot the same subjects together.
Here, I've used a
standard camera setting for photographing the moon, but I've also
experimented a little.
< F9, 1/160,
iso100, 75-300mm at 300mm. Only change to the picture was just resizing.
< In Adobe
PhotoShop or Picasso (available for free from Google) use the crop tool
to cut out the moon.
< And Bob's
your uncle.
< Same photo
but sharpened. Still, there's some noticeable blur, this is due to the
quality of the lens, and perhaps some quality of the tripod, too.
< Red moon rising. At
the end of the rice harvesting season farmers burn off much of the
stubble remaining in the field to unlock minerals and nutrients for the
soil. Sony Alpha 200 with 70-300mm G, f5.6, 1/25, iso100. 4th Sept 2009.
