Today I’m gonna dedicate this blog page to talk about Filters. when we talk about Landscape, Long Exposure Photography we must talk about filters, so let’s start…
so when we talk about filters there are two types.
1. Screw- In Type
Screw – In Filter are very easy to find and this the filter type we all start using filters. In screw- in type we can use its thread fo mount filters to the lense. so you’ll not need any other adaptor or anything to mount it to the lense. But the biggest disadvantage on this is it doesn’t support for Ultra- Wide lense & Fish Eye Lenses & the vignetting is very harsh. Also screw in has a good advantage, as the it has has very minimum light leak.
However if you want to buy a screw-in type filter you must aware of the diameter of the lense.
2. Slot – In Type
this type is totally different than the screw-in filters as it needs a Adaptor & a Holders to mount filters to the lense.
Also Slot- In Filters are expensive than Screw- In Filters, and the below advantages are the reasons for the high prices.
- You can mount many filters without having any vignetting.
- Easy to use as Replacing filters in the field is really fast and comfortable.
- Some slot-in filters are not available as screw-in.
- The only type for Ultra-wide & Fish eye.
There are various sizes of filter systems yet 100mm Filter System is the most used filters system. here we don;t want to change filter system just because the Diameter of the lense changed as we can have a Filter Adaptor as per the lense size.
The other thing is we can rely on different brands. for a example we can use Lee Filter Holder with NISI Filters.
Now Let’s talk about the filter types…
In the market we can find various type of filters. so let’s go one by one.
- UV Filters
Actually UV filters are the beginning of the filters and even of our photography life. As it means UV filters are reducing the effect of UV rays but today this function is already integrated in your camera. But nowadays this filter is often used only as lens protection from scratches and dirt. but I still find it unnecessary.
- ND Filters
ND Filters are very famous among landscape photographers. It’s really useful when do Long Exposure Photography.
ND Filters available in both Screw – In & Slot In. As well just because we have filters we can’t use it. we will need to learn about the shutter count depend on the filter value.
The below chart will explain you how to use them.
By the way I don’t encourage anyone to depend on this chart. what I am saying is use it as you want it, and get the best out of your filters. it’s good follow the chart for you knowledge but instead of depending on a chart try to do it practically.
After seen above chart you may think that you’ll need so many filters. Hey! No, you don’t need all of these filters, maximum of 3 filters are good for long exposure photography.
As I. always in to seascape long exposure photography I use 3,6,10,15 Stops filters. The 15 Stops is bit too much so you can ignore it.
- GND Filters
GND filters also work like ND filters. The above chart is also valid for this. Unlike ND Filters these GND is transparent side while the other half is dark. As your camera isn’t able to see at the same time very bright areas & very darks, you can use these filters to cover with the dark (ND) area the bright area of the scene, matching its brightness with the darker area of the scene . there are few types of DNG’s as Soft Edge, Hard Edge, Reverse, Blender.Below you can see Soft Edge & Hard Edge GND Filters
Tt’s a never ending subject to write, so let’s meet once so we can do use these filters practically or else I would come up with a Video Tutorial.
- Polarizing Filters
This is also very important to do Landscape, Long Exposure Photography. we use this filters when shoot water falls, seascapes or where we are affecting with glares and this also reduce the Haze when shooting Cityscapes. Also the polarizing filter helps to add some contrast to the sky & Clouds.
So in a very short note I have explain and given a very basic knowledge regarding filters and what does it do. I hope you will have something to get from this article and I really appreciate your support, so Please comment if you have anything to raise as a question or any feedback. it helps me to write more for you.
