wat filter to use under fluorescent light?
Hi there...
Well it depends on whether you are talking film based SLRs or Digital SLRs.
With digital SLRS like Nikon 70, they have a digital filter built-into the camera which you can select via the white balance setting.
For traditional film based SLRs, there is no special anit-fluorescent film you can buy that will off-set the flourescent effects.
The general filter would be the FL-D filter. This is the universal model code for this filter regardless of whatever brand you buy in the market. It is basically a pinkish looking colour filter that will off-set the greenish tint of the florescent light for general daylight film. But there are also two others type available too.
They are FL-W which is for warm white or white flourescent light fixtures and FL-B which is rare as you use this only when you shoot tungsten film under flourescent lighting condition. Tungsten film, in case you are not aware is film that you normally would use when shooting in warm lighting like those yellow filament bulbs. You need to use tungsten film so that you can "cool" down the warm yellow/orangy tone that will effect the picture. So this type of FL-B filter for flourescent is rare as this type of film is also rarely used.(more costly too)
I use to have the FL-D filters but rarely use it as, creatively speaking, sometime I find the greenish effect of the flourescent can be use to good effect especially when it is a scene that has also other forms of lighting (bulb, halogen, evening sunset or various type of fluorescentlighting fixtures) intermixing to give a very interest look to a picture.
Another reason why it is seldom used or at least by me when I was still shooting SLRs was that, this FL-D is not 100% effective. It never claim to be too...no matter what brand you buy. For one thing, lighting comes in varying temperature...same goes for fluorescent too, they have varying temperature too depending on brand and types...etc. In order to truly maximise the effective use of such a filter you would need to get a colour temperature meter to measure how much of a difference it is and then order some more specific fluorescent filter with the right counter tint to rectify greenish cast.
These days with a digital camera, you can basically take out the fluorescent cast by selecting the anti-fluorescent mode (fine tune it with the - & + setting) but just like with SLRs, it is still not 100% fool proof but at least you can still download the picture to your PC's photoshop and reworking the colour cast further.
That's my two bits lah...hope it does answer your question in part.
