Right thought i would do a small how to use filters(mainly grad filters)
ok so there are two ways you can use graduated filters;
1. with a filter in front of the lense before taking the shot
2.During the editing stage (post process eg in lightroom)
--------------------------------------------------------------------
1. Cokin P system (filter in front of lense)
here is a pic showing the setup of the cokin p system. main things you will need to use this system are as follows;
- Adapter to fit your lens thread size
- Filter holder
- Filters (wide range of filters can be used)
Adavantages of using this system is that you will see a 'live' image of what you are going to shoot with the filter in place which may influence the angle/postion/location you shoot.
2. Post process filters (Using Lightroom)
Lightroom's graduated filter tool can be a very powerful tool when used correctly and can turn a seeming dull picture into a more exciting one (example further down).
Here is a screen shot of the grad filter menu in lightroom
Key things to remember using this tool;
1.To apply the filter and keep it horizontal, hold down the shift key(dont know what it is on a mac!sorry)
2. Each picture will need differnt settings on each slider so play with them until you get the result your after.
3. Colour can be added to your filter which acts inependantly from the image itself therefore you can have a B&W image with a hint of colour from the filter which can give a nice effect.
here is a prime example of what a graduated filter can do
