Using Neutral Density Graduated Filters

A split graduated ND filter reduces the amount of light (lumen) coming into the (normally) top of your viewable frame.

In doing so it helps the film balance out the light variance so it more accurately sees what the human eye can see...

A split graduated ND filter reduces the amount of light (lumen) coming into the (normally) top of your viewable frame. In doing so it helps the film to balance out the light variance so it more accurately sees what the human eye can see.

It's very useful in gaining foreground detail when shooting into an expansive landscape that has a full or near full sun it. Because it is graduated, there is no defining line that will show up on your exposure, but you may still want to place the clear part of the filter on an area that will help 'mould' it into the picture i.e. where dark mountains turn to bright glaciers.

Many photographers also use a hard split, where there is no gradual reduction, ideal for when you have a sunrise shining off a mountain wall or peak, but the glacier or valley is still rendering a murky darkness.

You can buy these filters at all photo shops - they are indispensable for serious landscape photographers.

Summary:

• Get a 1 stop and a 2 and/or 3 stop filter and use them - your images will come alive and finally start to show all the detail you saw in your own eyes when you took the shot.
• Don't overdo it - too much ND filter will be obvious and isn't flattering to your capabilities as an outdoor photographer. You will rarely need to reduce any part of a frame more than 3 stops.
