Digitally Manipulated?

[Airplanepics]

It look's like you've also used too much saturation? The colours look slightly unnatural to me.

yeah the digi manipulation comes from the noise reduction, I bit too much I'm afraid. and the compression in #3 I'm guessing is reffering to the jagged lines of the fuselage.

Hi all,
could some kind soul point out where the "digitally manipulated" faults are for these two:

(Possibly the noise reduction on the skies?)

...and the "JPEG Compression" fault on this one:

All three are "Over/Under Contrast". Am I right to assume the shots were faulted for overcontrast?

I really need a sense check. Thanks in advance.
