Thanks boss!

Another question.. Maka cause ba "chromatic abberation" (if it's the right term) ang square filters? If so, how to avoid or minimize it?

Nipalit gud ko generic then gi testingan nko, weird ang result naay fringes ang edges sa subject/s.

What brand of filters were you using?
Also in what environment?
How did you hold the filters?

unsa na ND imo gamit? naay ND2, ND4, ND 8 then Nd 400 sa hoya na line. So if ND 2 lang imo gamit then minus 1 stop lang na sya sa imo actual exposure. so basin kulangon gihapon. ang uban gani mo stack sila nd400 (9 stops) plus CPL( minus 2 stops ata).

About sad sa sunset or sunrise. uban mo gamit gihapon ani pro para nako sobra na kataas ang exposure..Lisod timing pro maau sila mo timing :P ako dli kabalo.. ako gamit for sunset or sunrise. GND filters.. ( na tunga ni sya) meaning ang katunga is dark ( minus 1 stop or 2 or 3 stops depende sa rate) ang other half is clear. Thus if mag meter ka sa foreground during sunset. so mo over expose na imo sky, meter the sky then e minus nimu pila ang exposure difference nila. Then gamit GND depende sa exposure difference(-1, -2, or -3). Put the dark half of the GND on top, thus evening out the exposure of the sky and imo foreground.

ND filters na ako gamit is isa ra :P Screw type hoya ND 400
GND nako am using cokin P holder and cokin ND4 and ND 8 ata. planing to add ND2.
Advantage gamay ang cokin (or if china tianya) during sunset or sunrise shoot if paspas mo change ang exposure then maka ilis ka kay i slide man lang nimu ang filter. ang screw medyo ma awahi ka..

pro naa naman sad screw type na multi ND.. :P mura CPL ang movement then kada twist nimu lahi ug ND rate.

ND8 is only 3 stops.. so if inig calculate nimo sa exposure. say 1/1000 (day light @ noon) @ F 8 ISO 200.


If 3 stops lang as you can see kulangon na sya. So if mo down ka to f22 thats pila ka stop from meter exposure nimu na f8, 3 sakto ba? noob pako ani.. so in total.. -6 tanan. so to expose properly naa ka sa 1/30 na shutter @ f22 iso 200.

Gusto ka long exposure during a bright sunny day. ND400.. or B+W 110..

naa link dre sa flickr nag discuss ani.

mag meter man ka sa imo exposure dba?.. say para sayon ha.. ato e constant ato F stop (aperture value @ f22) normal nimu na exposure(without the nd is shutter 1/500 aperture @ f22 ISO 100.. So if i butang nimu ang ND8. To properly expose imo man gi kuhaan ug 3 ka stop sa light meaning underexpose na karon imo pics if shoot ka at the same setting @ 1/500, f22 iso 100. So imo buhaton is addan nimu ug 3 stops imo shutter para sakto imo exposure. So 1/160 ata tulo ka click sa imo shutter knob so dli jed enough para sunny day. :P

ambot lang sakto bana settings ako gi hatag as what ive said nag tuon pa ko ani sad heheheh

@bai tikboy :

naa ba'y baligya B+W 110 or Hoya ND400 nga square filter?

Sa eBay puro raman "screw-in" type akong nakit-an gud.

Mahal2x pod raba, unya kung mag upgrade tag lens (with bigger diameter), di na ni mo-sakar.
