In the film era a vast amount of filters was needed to alter the colours, the temperature or to add certain effects to the photos. In digital photography many of these filters have become pretty much useless as they can be recreated in post processing with the added bonus of more control over the effect without any disadvantages.
But there are also some useful filters which can’t be fully recreated in post processing and still have a place in digital photography and these are the ones I’m going to talk about. Update 09/27/2016: at Photokina 2016 in Cologne I checked out all the big filter manufacturers and have updated some sections accordingly. I am also working closely with NiSi filters now – not just because I think their filters offer the best quality – but because they listen to their customers and I hope to be able to help them develope the first holder I find nothing to complain about 🙂
For me it has been a great practice to visit the same subject close to my home again and again and it has taught me many things:
How different lighting affects images, until today I am often astounded how much light can affect my images and I constantly learn about new types of light and with which subjects they work
It is a good way to improve compositional skills, because you can compare different compositions of the same scene an see which compositions worked and which did not
It helps to discover new perspectives, with time the known perspectives will become boring and I will feel an urge to discover new ones
Well that’s at least how it works for me, but I think it won’t be that different for you. I wrote this article mostly to reflect on my own photography but I hope it might give you an idea or two as well.
