Hi all,

Noob here considering purchasing my first GND.

I intend to do long exposure photography for some landscape shots and naturally tempted to look at the B+W ND110 or the Hoya 9 stopper for the kind of drama that I see in flickr.

Q1
But is it too extreme for other NORMAL NON-EXTREME considerations like day-time, u just wanna get more background and a fill-in flash on the subject at hand? Can that double up? Pardon the ignorance. Because my natural instinct would be that a +4/6 would be good for such cases. I do have a CPL which should give me a +1 anyway.

dearchivism shifu had explained it in another thread... just quoting from here,



Q2
and is the +1 stop btw the B+W and Hoya enuff deterrant against purchasing Hoya? Of course B+W is insanely unavailable while I can get the Hoya fairly readily.

Thanks for answering as I hope to purchase one this weekend and do some shooting to start it off. :D

Are you asking about ND or GND? Totally different things and for different purposes/usage.

502 is 2 stop GND filter friend..

tat said, Why do u want to use an GND for portraiture works? And GND is recommended to get Slot in type so placement is relatively eaiser (according to where ur horizon is)

Normally a 2 or 3 stop ND or CPL wil come handy for portraits if u want to ultiize max sync flash while not compromising on stopping down on ur wide aperture lens ( to obtain fill light and nice oof areas result)

Blur sia when i see ur thread... :bsmilie:

TS, I lost you halfway through your first post.

Forget the ND GND fitlers. Just tell us straight, what are you trying to achieve?

ND110 = 9.5 stops ND. Which means, what ever shutter speed you have, if you put on the ND110, you will get a shutter speed one thousand times more. Shutter speed normally with no filter = 1/1000. With ND110 shutter speed = 1 second. You cannot autofocus with ND110 attached. And you might get some color cast from IR rays. I am not sure how you are going to pull it off with ND110 shooting portraits with flash.

IMHO, if you want to reduce the light, to use larger aperture and flash, you probably want something in 1 to 3 stop range. For that, a cheapo Hoya will do. CPL will give you 1-2 stops already (depending on the brand).
