Timelapse Photography for Video

Posted in Films with tags , , on November 18, 2009 by Ron Risman

I finally purchased an intervalometer / timer for my Canon 5D & 7D (fits both) as I have been dying to do some timelapse photography for video. I decided to purchase an inexpensive (made in Hong Kong) Canon knockoff off of ebay for a price of $34 delivered (The Canon TC80N3 sells for $135) and it has worked flawlessly.

What is timelapse photography for video?

You set the camera up to take a series of still-frames that are spread apart from each other in time. For example, if you had the camera take one photo per minute for 5 hours, you would end up with 300 still photographs (60 minutes x 5). If these 300 still images were played back at a standard TV frame frame of 30 frames-per-second you would have a 10-second video that represents that passing of 5 hours in time. That’s timelapse photography – for video. Some professional video cameras can also be set up to record timelapse sequences in much the same way.

Since I have a love for low-light / night photography I decided to capture stars and then show their movement in a timelapse video. This isn’t something that can be done with a video camera, since a video camera just doesn’t have the low-light sensitivity to record a night sky. In order to capture the night sky with a stills camera you need to set up the camera to capture long exposures (20-40 seconds) and then have the camera repeat this step over and over again using the intervalometer.

With my new eBay purchase in hand I headed over to the Nubble Lighthouse in Cape Neddick, Maine
where I had a perfectly dark sky each night (went 3 or 4 times this past week) – an ideal set up for capturing the night sky. The moon did rise each night but not until after 10:00 p.m., giving me a few hours to play. Since the camera could only take about 1 picture a minute based on the long exposure of each image, a 3-hour period only provides about 4-5 seconds of actual video. A lot of work for such a short final product, but when done right the results are breathtaking.

I combined some of my favorite footage from the week with other video that I captured around the Seacoast this week. These look better full-screen so feel free to enlarge them.

Installing 32-bit Coldfusion 8/9 on Windows 7

Posted in Tutorials with tags , , , , on November 6, 2009 by Ron Risman

I spent the past two days trying to get ColdFusion 8 installed on my newly updated Windows 7 system. I will spare you the details, but let’s just say that it’s what you know (and in my case WHO you know) that can make or break this installation.

The problem I was having was that after installing ColdFusion8 Developer Edition on Windows 7 – I couldn’t get IIS to know that CF8 was there. The CF8 admin wouldn’t show up, nothing seemed to work. Then I figured that it had something to do with the fact that my install of Windows 7 was 64-bit and the version of CF8 I was trying to install was 32-bit. So I downloaded the 64-bit version of CF8 and it worked instantly! For some, that would be the end of it, but for me I had some custom tags that would no longer work in the 64-bit environment. I could either go through and re-write the code on every template that made use of these tags – or I could find a solution. I chose the “look for the solution” option.

I found the solution after 40 hours of research and install / uninstall attempts and trying many tips along the way. Ultimately it was advice from a website run by Jason Holden that did the trick. Here’s the all important link:
http://www.jasonholden.com/blog/index.cfm/2008/5/6/Coldfusion-8-on-Windows-Server-2008.

Here is a summary of the steps needed. See his site using the above link for more detail if needed:

The steps below assume that you have IIS 7.x already installed. If not you can install it by following these same steps:

  • In Windows 7, go to the “Turn Windows features on or off” setting. You get there through the control panel, then by clicking on
    “Programs & Features.” Look on the left column of this new windows and you’ll see the link for it.
  • In the “Turn Windows features on or off” window make sure that “Internet Information Services” is colored blue (selected). Click the + symbol next to it and make sure that Web Management Tools and World Wide Web Services are both blue (selected).
  • Under “World Wide Web Services” make sure that “ISAPI Extensions” and “ISAPI Filters” are both selected.
  • Click “OK” and let Windows 7 install these features
  • Once finished, Install Coldfusion 8 (32-bit) normally

Once IIS and the ISAPI filters are installed. Perform the following steps to enable 32-bit applications in IIS7.

  • Open up the Internet Information Services (IIS) Manager
  • Expand the server node and select Application Pools
  • Select the DefaultAppPool and then Advanced Settings
  • Ensure that Enable 32-bit Applications is set to True

Failing to enable 32-bit applications results in 500 Internal Server errors.

That’s it. I wanted to post this in hopes that this site will make it twice as easy for someone to stumble across the great advice that I got from Jason Holden’s blog. It’s important to pay it forward when you get great help from someone that I’m sure had plenty of other things he could have been doing.
