The new 660nm modified Canon SX240 (replacement) camera has arrived, from the ever helpful Andy at Infraready, to replace the broken Powershot n as my main infrared camera dangling from a kite.
The Indestructibles site lists the steps perfectly: http://www.instructables.com/id/How-To-Install-CHDK/
CHDK Download page: http://chdk.wikia.com/wiki/Downloads
One of the first things I noticed is that the SX240, unlike the Powershot n, will reload CHDK after images have been captured – which is great and so much more convenient than having to use a freshly copied SD card each time.
There is also a note on the Wiki that RAW capture does not work correctly when in Auto mode; not an issue, however, as my intention is to shoot purely in Shutter or Manual mode, when flying and Aperture mode when using normally.
The SX240 also has two good features, over the Powershot n:
- Custom white-balance – although capturing RAW with CHDK, this helps with the JPEG files when not using CHDK.
- Shutter Priority (“Tv“) – when swinging off a kite line, having a fixed shutter of 1/500 or 1/1000th is very helpful.
Will post the first sample images shortly.
