dunno why, ppl are really getting freaking selfish and just dun wanna help. dun wanna help then dun join a forum. sucks :thumbsd: is it really a chore to type again and help another person? the threadstarter is only a newcomer with 4 posts to boot. the forum is not that easy to navigate for a newcomer, much less easy is it to search for info. this is a photography forum. if they join this forum, obviously they hope to learn something from it. asking ppl to google is just making this forum a f-up place for newcomers.
so when ppl meet accident on the street eg. biker fall down from the bike, do u go and ask the biker "go and google for help from hospital for ambulance from the net"
CPL - a circular polariser, helps to reduce the reflection when u shoot through glass. also helps to make the sky more blue and grass greener etc.
ND - Neutral density filter, helps to reduce the amount of light reaching the sensor. main purpose of reducing the amount of light to the sensor is so that u can use a longer exposure. main aim is to create fairy smooth water flowing from waterfalls / calm smooth devine looking sea. If u do a normal short exposure, u will only get droplets of water falling from the top of the waterfall. with a long exposure, u can get a smooth stream of flowing water.
UV - in the film age, ppl use a uv filter to cut the uv light that reach the camera becos the uv light will damage the film. but now in the digital era, there is already a some sort uv protection thingy in front of the sensor, so there is no need for a uv filter. wat ppl use a uv filter for in the digital era is just to protect the front glass of the lens from scratches.
starlight filter - a filter that make light that emit out from lampost literally in a star shape. creates comic like effect.
