This is a question I've been asking to myself from a while, and especially after I saw this video from Thomas Heaton a few weeks ago, where he says that you can get away without ND and graduated filters, but you can't replace a polarizer, as the latter cannot be replicated in Photoshop unlike the other two. And I agree with him for the polarizer, and for the Graduated filters, which is probably one of the few times where I totally regretted buying them. I was excited about those at first, but after a while I realized that they were mostly useless, as you can achieve better results just using bracketing in your camera and using the graduated filter in Lightroom.
But can we say the same for Neutral Density filters? Can just take some photos and then merging them together in Photoshop achieve the same results as a proper filter?
Since I've been started to do long exposures a long time ago, I always used ND filters, first I started with very cheap Cokin filters, which were terrible, very easy to scratch as they were made with some cheap resin, they made any photo on the magenta side, and just forget about sharpness, that one goes straight to the bin.Read More
