Well, I didn't notice this thread before, so I replied on the sx10 thread. Anyway, the chdk can save dng files, but for some mysterious reasons, it is almost half the resolution. Could not get ANY software to recognize the crw files. Picasa and irfanview can open the dng files, but my other existing, NORMAL editors are not recognizing them. Picasa can save to jpg only, and doesn't have any NR or exposure adjustment facility. Irfanview is great, and can utilize photoshop plugins, but it's RAW files aren't doing any good elsewhere. Also, since the dng files are low res, I'm not happy at all.
