Each shot is 'ok', with the following exceptions, made all the more obvious looking at the series as a whole ...
... why the different exposures?
.... and white balances?
Focus and compositions are good though,
Is there any reason why in airplane shots like this... Ive seen a few... the clouds have a reddish tint in it? I have the same thing in my pics of the recent airshow. Im assuming those pics that don't have the tint, more PP'ing (or advanced PP) was done?
