This time lapse video of a cloudy sky consists of 2400+ images taken over the course of 8 hours, one image every 10 seconds, from 11:30AM to 7:30PM on Saturday, September 10, 2011 in Pennsylvania, USA with the camera setup on a tripod at a window on the second floor of my house. This is only my 4th time lapse ever, and my first attempt at an extended period such as this, so I am still learning. I used a Canon Powershot A590 loaded with CHDK using the “Ultra Intervalometer” script set as follows: Delay 1st shot 10 seconds, Interval 10 seconds and Endless=Yes. The camera was set to Program mode, Widescreen resolution and no exposure compensation. In hindsight I should have set it to at least a -1/3 stop to account for the sun as it moved across the sky as some images were somewhat overexposed. Images were saved to a 16GB Sandisk SDHC memory card.. Once the images were transferred to my PC I then used VirtualDub to open the first image of the sequence. I then applied the following: 10 FPS, Resize video filter set to an Absolute pixel height of 1440; Levels video filter to tone down the brightness down and correct overexposed images and finally video Compression using Xvid codec with Quality set to 1.

Canon has come out with another point-and-shoot camera in the form of the Canon PowerShot A590 IS. This 8-megapixel camera has image stability, a 4x wide-angle optical zoom, full manual controls and many other great features. Best of all, it isn’t as expensive as some digital cameras but still gives great value for your money.
At first glance, the Canon PowerShot A590 IS may look bulky and uncomfortable to the hand but it is actually very compact. The AA battery compartment gives users a good handgrip and a thumb rest is conveniently located and the upper right corner of the camera’s backside. This camera can also fit in purses and even pockets so it can be taken anywhere and everywhere. The smooth and round body of the A590 also adds a comfortable feel whenever it is held by the hand. Of course, even though this camera provides a fine grip, a wrist strap is always a good idea.
