 Thanks for the replies, this list is great and I appreciate you all 
taking time to respond. 
So the bit depth on capture determines how detailed the information is 
sampled, if an image is sampled at 8 bit changing it to 16 will not 
add information that was not originally sampled at that depth. 
Although Clayton is saying that he sees less destruction to the image 
if he converts 8 bit to 16 bit before applying a fair amount of 
adjustments. So while converting doesn't add info it does less damage 
to the file when applying adjustments? Amadou, C David what about 
image degrading when lots of adjustments are applied? 
Thanks again
