Are you saving new pictures to SD card? Try saving to internal storage... Have you tried any other Camera Apps to see if they also show poor results?
Try Camera360 Sight or ProShot.
"Destroying" is vague. Without seeing sample pics it is hard to advise further. Some just do not like the new processing algorithms in 10. You may have a deeper issue.
Is Camera up dated in the Store?
Have you tried a Soft Reset or Hard Reset? Sure your SD card is not corrupted (if that is the save location)?
