Also,alwayschecktheweatherreportforyourdestination.Checksunriseandsunsettime,weatherandwind.Then,planaccordingly.Generally,thesearethecriteriaIconsider:sunny,cloudy(overcast),andwindy(sometimescertainbirdsdon’tgohuntingwhenit’swindy,pluswinddirectionhelpsyoudeterminethetakeofforlandingdirectionforcertainspecies,suchasSandhillcranes).Ifitisasunnyday,youcanfollowtheSunny16rule.Ifmyobjectiveforthetripisbirds-in-flight,Iusuallysetmycamerameteringmodetomanual,andsetthecameratof/7.1,1/2000s,ISO400.Thatshouldbethepre-tripcamerasetting.Forovercastdays,it’strickier.Iwilltalkaboutthatlater.
