How to Use the Graduated Filter - Adobe Lightroom Tutorial

Is the software version of the Graduated Filter better than the real thing?

In this video tutorial we look at the power of the graduated filter tool in Adobe Lightroom.

A neutral density graduated filter is used to control exposure across your scene when you have two  different exposures in your shot. An example of this is on the majority of landscape photographs where the sky is around 1 to 2 stops brighter than the foreground. The filter attaches to the front of your lens and darkens the top portion of your frame. This can be adjusted depending where your horizon line is.

I have talked before about how the usefulness of these physical filters is in serious decline.

Essentially, if you are shooting RAW, in many circumstances the dynamic range of modern cameras will be able to capture the scene without the use of the physical filter. Once your picture is put into Adobe Lightroom or camera Raw the computer can pull the detail out we are looking for using the graduated filter tool.

It does this by using the graduated filter tool. It is very easy to use. Simply select the tool, drag a gradient across your image, then you have a range of adjustment that can be made to that gradient. This is more useful than the physical filter because other adjustments can also be made to the gradient than exposure alone. Contrast and highlights are obvious examples but the ability to adjust white balance gives the ability to adjust the colour of the sky where the RAW image may not match what your eyes perceived at the time.

There is no suggestion of cheating as you are only bringing back detail using the graduated filter that was already present and probably also what your eyes perceived.

Camera Filters - Do We Need Them on Our Lens?

The Truth About Camera Filters

In this video we take a look at various camera filters and whether you actually need them.

There are many kinds of filters in photography from those we put in front of our lens to software effects in Photoshop and filters on Instagram. They all in some way manipulate our images so accusations of 'cheating' from purists about filters added in post-production I find tiresome. Here we look at the most popular physical filters, talk about how they are used, whether they are needed and discuss any software alternatives.

UV Filters

These are probably the most common type of camera filters and screw to the front of your lens. They claim to block out UV light that can be detrimental to your image. The truth is they are a relic of the film era where film was susceptible to UV light and caused your image to appear hazy. Digital sensors on the other hand do not suffer this problem so the filter may only serve to worsen your image through a slight reduction in contrast. The main reason they are still used however is to protect the expensive piece of glass it is attached too. This is really a personal choice so if they bring you piece of mind, go ahead and use them.

Neutral Density Gradients (ND Grads)

It is possible that ND Grads and filter systems such as those from Lee and Cokin were designed purely to give landscape photographers a sense of superiority and smugness that would intimidate other photographers into never taking another landscape shot again. In reality they are used to balance the exposure between the sky and the rest of an image as the sky is generally much brighter than the ground. The difference is usually anywhere up to around 2 stops. There are hard gradient versions and soft gradient versions and which one you use will depend on how defined your horizon line is.

Whilst the effect these camera filters produce is essential in the majority of landscape photographs, the physical filters themselves are not. They are generally large, clunky and difficult to use along with being expensive. Although you can attach them to different lenses with an adapter, they do not scream versatility and ease of use. With the ever increasing dynamic range of modern cameras it is rendering ND grad filters pointless. The effect can be added very quickly in Lightroom bringing out all the detail of a bright sky or darkened foreground as a long as you shoot in RAW.

Neutral Density Filters

Neutral density camera filters are used to reduce the amount of light coming into the camera by allowing us to use a longer exposure time, or a wider aperture, where otherwise it would be over exposed. ND's are used in video to allow large apertures in very bright conditions to ensure you still get a nice blurred background for you shot.

With stills they allow us to use long exposures to smooth out water or show movement in the image.  They vary in strength and filters like the 10 stop 'big stopper' allow for some extreme long-exposure photography. There is currently no way to imitate the effects of these filters in software so they remain vital in many photographers camera bags.

Circular Polarisers

Circular polarisers are used to darken and saturate skies and remove harsh glare from water. It does this using science that you can read about elsewhere but the intensity of the effect can be controlled by rotating the filter.

It is a pleasing effect that is not easily added in post-production so remains useful in certain conditions. If there is no blue sky and no reflections or glare then it will serve no purpose other than reducing your exposure by about 1 stop.

Many of these filters can be combined and screwed together to achieve several of the effects in one shot. Just be careful when using extremely wide angles though as the camera might 'see' the edge of the filters creating a very harsh vignette in your image.

Filters can be an expensive addition to you camera bag. Before buying, decide what type of effect you want to achieve and tailor your purchase to this. Personally I shoot a lot of long exposures so ND filters spend a lot of time on my camera. I use circular polarisers now and again and increasingly leave the ND grad system and UV filters at home.
