Destructive is that it is actually changing pixel valvues permanently whereas the adjustment layers is not actually changing pixel values. Here is a link to Adobe's brief explanation of adjustment layers. http://www.adobe.com/designcenter-archive/keyconcepts/articles/concept_adjustmentlayer.html

I don't understand your statement of "destructive" when it creates an "improvement" to the image.
a question - not a challenge.

One thing about the image>adjustments>brightness/contrast is that it works a bit more destructively than does an adjustment layer. The wonderful thing about Photoshop is that there is more than one way to do things and dependent upon each individual's workflow one method may be a better fit than another.

I was just reading the thread on creating your own Gray card -
the gray card just adjusts the lighting for 18% or so. What I do with "All" my photos is adjust the contrast in
image>adjustments>brightness/contrast +18% contrast and maybe -6 to -10% in brightness this always seems to add some snap/clarity to every photo.
IMHO
