Photography Filters:
============
1.Warm –up filter:
A warm up filter is an orange colored filter which is used to give a scene a warm look, almost as if the sun is shining extra hard. It is perfect for overcast days when scenes look boring and uninviting.
The warm-up is generally given the code no (81) and the filters range in strength from A to D. The best general purpose warm-up filter to buy is an (81B).
Like most filters, a warm up filters absorbs some of the light going into the camera so u needs to keep an eye on the shutter speed. Luckily any exposure alteration will be handled by an SLR’s TTL metering
2. Polariser filters:
It’s a dark filter which, when fitted to the lens, boots color and improves contrast.
With the filter attached to the camera, it has to be rotated to vary the polarizing effect. Look through the lens and while turning the filter لاice how skies darken and reflection on windows disappear.
To work at its best, the polarizer must be positioned at 45 degree to the light source. It works best on bright sunny days and is the perfect filter to take on holiday when blue skies are guaranteed.
Used with a wide angle lens, a polarizer is perfect for making the most of color. Get up close to the telephone box and shot from a low angle looking up at blue sky. A perfect situation for the polarizer!
Being a dark filter, a polarizer absorbs a lot of light so you’ll need to take care with exposures. When your camera says a scene is, say 1/250 sec at F/8 without filter, it will drop to 1/60 sec at F/8 with the polarizer attached! To avoid slower shutter speeds turning into camera shake you’d be advised to carry a tripod with you whenever you go out to use a polarizer!
