Hi,
I couldn't find anything about this already on the forum. I've been trying to shoot raw using my SX230 HS, firmware version 1.01a. I've managed to get .dng files, which I'm delighted with, except they have huge numbers of bad pixels.
If I zoom in on any part of an image I can see loads of little groups of 5-10 pixels that are usually blue, cyan, magenta or black but can be other colours too. These are not present on the corresponding .jpg files and I'm wondering what I have to do to get rid of them.
Obviously I have created the badpixel.bin file as it is necessary for shooting DNGs. I read in the user guide that I should also create a file called badpixel. I tried to do this using the show_bad program but it didn't recognise the raw file that I gave it.
Has anybody else had this problem?
Thanks a million in advance,
Curly
