HIGH ISO SENSITIVITIES:
Even with a slow shutter speed at very high aperture setting,
the camera will still not get enough light to create a photograph. In order to
brighten the photograph, a higher ISO sensitivity is required. Do not be afraid
of using higher sensitivities.
When using f/2.8 lens at f/4.0 it will require much slower
shutter speeds. The reason why we do not recommend using slower shutter speeds
is because it will cause the star to leave streaks. Instead of using slower
shutter speeds, simply increase the ISO sensitivity. FIGURE
SUGGESTED EXPOSURE SETTINGS:
Based on our experience, these suggested exposure settings may
or may not help you to accomplish the result as desired. Give one or two of the
exposure settings a try.
·
4s @ f/1.8, ISO 800 (with f/1.2 lens)
·
5s @ f/2.0, ISO 800 (with f/1.4 lens)
·
10s @ f/4.0, ISO 1600 (with f/1.8 lens)
·
10s @ f/2.8, ISO 800 (with f/2.0 lens)
·
10s @ f/4.0, ISO 1600 (with f/2.8 lens)
·
10s @ f/5.6, ISO 3200 (with f/4.0 lens)
If the photograph is underexposed, slightly lengthen the shutter
speed or increase the ISO. If the photograph is overexposed, slightly shorten
the shutter speed or decrease the ISO. Remember not to exceed 20s shutter speed
and using much higher ISO will add more grain. 887
MENU SETTINGS:
We will now go in to the shooting and custom setting menu to
make tweaks to some of the settings. If your camera does not support one or
more features, simply ignore it. Watch this short video for settings
TRIPOD COMBINATION CHOICE:
A quality sturdy tripod legs a head combination is recommended
Gitzo or Manfrotto brand tripod legs and heads for their steadiness. We do not
recommend using a cheap and low quality tripod because they are not rigid
enough to prevent the camera from wobbling the tripod as the shutter mirror
raises or drops.
Unfortunately, even with a top of the line tripod legs and head
combination, it does not hold the camera perfectly still when triggering. A
heavy weight sandbag placed on the top of the camera and lens setup on the same
axis with the tripod head is recommended to absorb the vibration that is caused
by the camera’s shutter mirror, as it is being raised and dropped. By helping
the camera stay still, it will dramatically improve overall sharpness. The
sandbag must weight greater than the weight of camera and lens.
The ball head or geared (tilt/pan) head must have a weight
capacity that is greater than the weight of camera and lens setup and sandbag.
