What kind of color processing did you do on the images?
Images are straight out of camera, I just used custom white balance, set on a piece of white paper. The pictures were then cropped and resized in VirtualDub.
Theoretically one could shoot in RAW and then perform full processing (swapping channels and other popular IR photography tricks), but since RAWs are some 18 MB here, I could store much fewer of them (while a 6 MPix JPG is under 1 MB).
what this? please link? i need...
It's the first script on this page:
http://chdk.wikia.com/wiki/User_Written_ScriptsI enabled focus lock - this way I can use autofocus reliably by first pointing the camera e.g. at the mountains, and then reframe towards the sky. Thanks to the initial focus lock, I'm sure the focus won't get lost by camera attempting to set it on clouds or on clear sky.
