A Commentary on Photo Legitimacy

To butt in... my personal view is if it's evidence then the obvious thing is to produce the original untouched image then also a possibly brightness/contrast/gamma /sharpening  enhanced image alongside it if it is needed to show desired detail.

But proving that the original is totally untouched is the problem.

Evidence/news/documentary is such as above, untampered with as to detail - but for personal use, artistic use or advertising, then anything goes, and the honest person (rare it seems) should declare what has been tampered with.
