Sony has announced “Digital Filter”, a new camera app that mimics the use of graduated ND filters. It allows you to divide the scene you’re shooting into two or three areas and set exposure and white balance for each of them separately. As a result, you can get an image with balanced light when shooting sunsets and other backlit landscape scenes.
This is a topic that seems to come up every few years. As sensors increase in dynamic range, ND grads sometimes aren’t so essential. Raw processing software becomes more capable with each new release. Even filters that cut through haze aren’t always needed. But what about things like circular polarisers and big ND filters for super long exposures?
In this video, landscape photographer Thomas Heaton offers his insight and thoughts on the question. When it comes to polarisers, Thomas is of the opinion that they absolutely are necessary. It’s an opinion I share. The function that they serve just cannot be reproduced in post. But what about the rest? Watch the video to find out.
Benjamin Von Wong – Montreal Based photographer here! I recently reviewed for you a set of teleconverters, and this time wanted to follow up with a set of Graduated ND filters from Cokin supplied to me during my trip to Africa by the nice fellows over at B&H!
As you may probably know, a graduated ND filter is essentially a square plate of glass that darkens the image gradually from top to bottom. What’s fun about the filter set from Cokin is that it comes with various “densities” of darkness that are stackable. What this means is that you have a pretty good control over how big of a change in dark-light transitions that you can do. Additionally, since the filter rests on a ring, you can rotate the filters to manually control the angle of the gradient! [Read more…]
