I’m using the Nik Collection tools for a while now, but for whatever reason I didn’t know that they have some good webinars on their website. I stumbled across that when I was watching one webinar of them on Youtube, the one about Silver Efex Pro:
You can find around 75 webinars there around their products. I love their Silver Efex Pro Plug-In for my Black & White conversions, so I’ll digest that now.
Hope that helps you as well!
