To be equally blunt...I never said I was an expert or professional graphic editor.
And besides...who said I used Photo Shop? I didn't. Too rich for my blood.
I can say, that outside of the area of the water mark, I touched nothing on the aircraft. The photo enhancement of the shading, contrast, saturation, shading, and sharpness may account for what you are describing though.
Anyhow...you can use it or not...like it or not...or say whatever you want about it.
I simply posted it.
But you have a great day.
