Filters

I just bought a new filter recently. Its a graduated filter (grey) or widely known as ND grad filter. It simply filters out light at the upper part of the lens and reduces its effect to zero at about halfway or middle of the lens.

Why do we need this kind of filter? Well, it is essential if you are a landscape photographer. I'm not a landscape photographer...maybe not yet. Soon to be? hehehe (lets say i'm a 'jack of all trades' haha) . The filter is usually used to make the burnt out sky darker and the darker land brighter. OK let me put it like this. When we take a landscape photo, the result looks like this (see below):


The camera assumes that it is too bright (overexposed due to the sky). So the camera uses a faster shutter speed which causes the land to look darker (underexposed)

The photo below is the result of using ND grad filter:


As you can see, the sky is much pleasant to look at and the land is brighter and has much more details than the previous photo. (I used a circular polarizer at the same time)

And another photo...

I haven't got time to go out for taking landscape pix. All the above pix were taken from my house. I will post if I have new pix.
