watercolor orchids photo difference

Here's the difference between 

a $20,000 digital Hasselblad 

and a $600 Canon Rebel.  

Both of these images 

are from JPGs,

a "lossy" file format.

The photo original is 

a non "lossy" TIFF file.

The real original is

my 22" X 30" watercolor

of Anne's orchids.

Guess which is which.
