I have checked the 'save RAW', 'with JPG, and 'DNG visible via USB', but they do not show up, when viewing the SD card IN THE CAMERA. However, I can see them if I put the SD card into my card reader. Any ideas what might be causing this?
When I changed the extension to .dng or .jpg and looked at them using Helicon filter, they looked very strange.

Are you saving the original images as DNG or as RAW in the camera? Use .DNGCHDK .RAW files are not recognized by most PC software (depends on the camera model and the imaging library used by the program).
Hi, I set the 'raw file extension' to '.wav' and checked off 'DNG format' in CHDK.Then I took a picture, which showed up as a wav file, on the camera's SD card, via the computer screen. I then changed the the wav extension to dng and viewed it in Helicon filter. Then I changed it to jpg, and again viewed it in Helicon filter. Both the dng and jpg versions looked odd. I did this with all the raw file extensions in CHDK; but the wav extension was the only one that showed up while viewing the SD card in the camera. The others appeared when I put the SD card in my reader, but I didn't open them....... john

However, Windows (7) explorer will not allow me to change the file extension while the SD card is in the camera, only if it's in the card reader; which defeats the purpose, because dng files show up in the card reader anyway. The entire issue is resolvable if I simply remove the SD card from the camera and put it into the card reader, which is what I will do in the future.
I was told that taking the card in and out of the camera gets the contacts dirty,
