Canon PowerShot S100 Shutter Speed Experiment

Today I tried out a new gadget that I hope will be useful for demonstrating the effects of different shutter speeds for stopping action.  I set up my Canon PowerShot S100 on a sturdy tripod in Shutter Priority mode and aimed at the new gizmo, which is called the Super-Sized Light Doodler.  (I got mine from Edmund Scientifics.)  I haven’t yet explored all of the features of this device, but, as you can see in the first image below, it consists of a blue base with a ring attached to it.  The ring has a series of colored lights spaced around its rim.  When you turn on the machine, the ring rotates rapidly, and the lights flash in various patterns that you can change with dials.

I turned the Light Doodler on, and what I saw was basically what you see in the second image, which was taken at 0.3 second.  At that slow shutter speed, the image shows at least one full cycle of the ring, which paints a circular pattern, appearing to create a globe in mid-air.  After that shot, the other shots were in the following sequence: 1/10 second, 1/25 second, 1/60 second, 1/80 second, 1/200 second, 1/1000 second, and, finally, 1/2000 second, the fastest shutter speed available on the PowerShot S100.

There isn’t all that much to conclude from this experiment. I just think it can be interesting to see how the camera, with its series of increasingly fast shutter speeds, can stop the action of an object like the rapidly-spinning ring of the Light Doodler, and make images that look like completely different objects depending on what shutter speed was used. You don’t really see what the human eye sees in this case until the shutter speed is slowed down to almost half a second.

Miniature Effect Movie with Canon PowerShot S100

The book I’m working on now is Photographer’s Guide to the Canon PowerShot S100, which I hope to have completed by the end of this year, or sooner if possible. I recently got my S100 and have started experimenting with it. Today I’m going to post a short movie made with the Miniature Effect setting.

This setting, which is available in the Creative Filter shooting mode, blurs the sides or top and bottom of the image so the overall scene takes on the appearance of a tabletop model. With the S100, you can use this effect when shooting a movie; you can also set the camera to speed up the action so it appears 5, 10, or 20 times faster than normal.

I earlier posted a sample of a similar effect using the Panasonic Lumix LX5 camera, which got this capability with its upgrade to firmware version 2.0.  You may notice that I’m using the same scene for the PowerShot S100, because this is the best location that I have found for this type of shot.  The vantage point is high above the ground, with a view of several intersecting streets. This type of scene seems to  give good results, because the cars and trucks zooming around the streets (speeded-up) have the look of little models.

Anyway, even though the book is not done yet, here is a sample movie to illustrate the Miniature Effect with the S100, using the 10X speed-up factor. Click on the link below to view the movie.
