如何拍摄蓝天白云，有时蓝天拍出来了但是地面风景又会曝光不足？还有就是 逆光拍摄人像，背景也是蓝天白云

光比过大就是这种现象。
拍人物的时候可以先用评价测光使蓝天白云曝光正常，此时人物面部一定偏暗，再用闪光灯等辅助光源对人脸补光就可以拍出人物和背景都正常的片子了。
拍摄地面景物时由于景物体积较大或距离较远，闪光灯就不够用了，此时用渐变滤镜效果更好。先分别对天空和地面点测光，计算出两者曝光级差，之后调到m手动档，采用对地面测光的参数组合，再根据计算出的级差选用合适档位的渐变镜来压暗天空，就可以让天空和地面都曝光正确了。

i've been feeling down
i've been looking round the town
for somebody just like me
but the only ones i see
are the dummies in the window
they spend their money on clothes
it saddens me to think
that the only ones i see are mannequins
looking stupid, being used and being thin
and i don't know why i hang around with them
the way they act,
i'd rather be fat than be confused
the way they act,
i'd rather be fat than be confused
than be me in a cage
with a bottle of rage
and a family like the mafia
ba babala~

enjoy coffee,enjoy living~

i've been feeling blue
and i don't know what to do
and i never get a thrill
and they threw me out of school
'cause i swore at all the teachers
because they never teach us
a thing i want to know
we do chemistry, biology and maths
i want poetry and music and some laughs
and i don't think it's an awful lot to ask
so won't you please get up off your knees,
and let me go
so won't you please get up off your knees,
and let me go
cause i'm here in a cage
with a bottle of rage
and a family like the mafia

if my family tree goes back to the romans
then i will change my name to jones
if my family tree goes back to napolean
then i will change my name to smith
if my family tree goes back to the romans
then i will change my name to jones
if you're looking at me to be an accountant
then you will look but you will never see
if you're looking at me to start having babies
then you can wish because i'm not here to fool around

you can wish because i'm not here to fool around

you can wish because i'm not here to fool around~

you can wish because i'm not here to fool around

you can wish because i'm not here to fool around ~
