Darryl is kind enough to allow us to display his Flash movie created
from images from the VolcanoCam during the evening of May 04-05, 2005.
This is a special composite movie that superimposes a visible image of
the volcano within the movie.
Darryl did not initially see the bright light when he first created
the movie, as he does quite regularly. However, upon notifying him of
the event and at our request, Darryl went back and created an entirely
new movie after reprocessing the original images. That is the movie we
According to Darryl, "The shots from the webcam at night show a lot
of noise, as its not really designed for low light operation. In fact,
it is difficult to see much more than the glow and sometimes the hint
of a steam plume on the images. However, using image processing software
to reduce the noise and adjust the levels, it is possible to bring out
some of the details of the glowing steam plume and even the mountain
"By combining a number of the images into an animated sequence it is
much easier to pick out the details and get a sense of the steam/ash
plume(s) rising from the crater during the night. The [above] movie
was produced using approximately 100 frames from the volcanocam taken
[at] night. Each was processed using Neat Image (to reduce the noise),
converted to a grayscale image and levels adjusted before being assembled
into the final movie."
Because it is very difficult to actually see the volcano at night from
the VolcanoCam (even during a full moon and clear skies), Darryl superimposed
a daytime view of Mount St. Helens into the movie sequence for reference.
We offer special thanks to Darryl
Luscombe of Vancouver, British Columbia Canada for his personal support
to the Mount St. Helens VolcanoCam.
