It is rather strange that, having invested in cameras and lenses that give the most true to life images, we then invest even more in filters to make the pictures look lo-fi again. But we do.
The good news is that one of these filter packs has now become free. I've no idea how Google ended up selling a bunch of high quality filters for Photoshop and Lightroom, but they did. And now they've made the filters free.
The Google Nik Collection of filters is well worth having. There are some noise reduction and HDR ones among them which are OK, although these kind of things are probably done at least as well by some of the built-in features of Photoshop and Lightroom. However, the vintage camera and black and white filters are lovely. The set used to represent reasonable value at 85 quid. For free its a steal.
