yo guys, i just bought a tokina CPL filter
got a problem, hope u guys can help me out

i read that CPL can make the sky nicer(more blue)
enhance contrast, eliminate reflection on water and glass...

but i tried and feel that can't really see any differences...
wonder where i have gone wrong, i have also observe the 90 degree to the sun rule
and turning the front of the filter to adjust, but still not much difference...

wondering what could have gone wrong... anybody?

CPL can only enhance when there is at least a bit of a blue sky. Overcast and hazy skies are case gone. Mind to share a picture?

the exposure for sky is not tip-top here, hence any effect will be diminished, if you are talking about out of camera pictures.

but you should be able to see visible effect when turning the cpl in front of lens , through the viewfinder

if not, try it on NON METALLIC REFLECTIONS. if that doesn't work, then i don't know what you have bought, it is not going to be a cpl.

so... should i underexpose the sky or overexpose the sky to get better effect?

you should expose exactly for the sky to get optimal effect.

if you do not see it through your viewfinder, then something is wrong.

the blue should darken, if there is blue.

right now, in that picture, it is overexposed FOR THE SKY

but at least you can see building details.

a picture is made up of more than just one photographic element, when you talk about underexposure or overexposure, you need to take note of what elements you are talking about, especially for wide scenes where there are so many more to take into account.

as for what is the RIGHT EXPOSURE FOR PICTURE, no one can tell you, it really depends on the characteristics of your sensor (how wide the DR is).. and what you seek to achieve in terms of mood and output.

btw, i use caps to emphasize key phrases, not that i am pissed off hor. some people get the wrong idea.

oh.... i see....

but if i were to underexpose the sky more, the building would be even darker...
unless i use hdr?

and to see the polarizer effect more, i need to under expose the sky rite?

and where should my focus box points to? currently i am pointing at the building...

yes, or exposure blending, that is something you will have to learn when shooting such scenes, exposure is a big problem, and you have to think of how to counteract this problem.

you do not need to underexpose the sky. expose it correctly, that will be the maximal effect point.

pointing it at the building is fine.

yup. no pp done, only shrink the size

judging from this photo, the sun should be at your 10 o'clock position, what you intend to do with using CPL filter here?

Where is the blue sky here? It's a sunset/sunrise scenery where the blue of the sunlight is nearly gone and only the red parts of the light spectrum are left. Nothing to do for a CPL.
