Question,question,please???

I saw many of pictures where ocean,lakes,or rivers,shows a reflexion of the sun in dusk,or in dawn specialy,beside the water looks more realistic from what i see in my game,question its that a add-on diferent texture replacing the original from FS9 or its being edited by photoshop or any other edit prgm?,because i've done everything and always shown that awfull sea,looking unrealistic i saw i was normal,until i saw these amazing sreenshots here,all the grafics cities,mountains,etc,look same as mine,but im concern about the water detailed ???
