It is rare for me to convert my digital photos into black and white. I nearly always use medium format film for my black and white photography of the details along both the coast and the landscape of the southern Fleurieu Peninsula in South Australia. I avoid the grandiose or the panorama.
However, as I have no b+w film at the moment, and the spare film back for the Rolleiflex SL66 that I used to use for my b+w broke when I was in Queenstown earlier this year and cannot be repaired, I have done a quick conversion of a digital colour image into black and white using Adobe's Lightroom.
I dislike the way that Lightroom converts colour digital files into black and white files. The tonal richness disappears and the image becomes rather drab and flat. There is no punch to them.
So, like many others, I've been using the Nik Silver Efex Pro 2 plugin software to process my digital black and white images in Lightroom. I was happy with what I was using, and I didn't bother looking for alternative software because I rarely converted my digital photos into black and white. Digital black and white photography didn't really appeal.
This is just a small step into the world of digital black and white photography. Though I will eventually buy more black and white film to use with the Linhof Technika 70, the new iMac (currently running the High Sierra O/S) is forcing me to think in terms of upgrading my Sony NEX-7 digital camera to a full frame mirrorless one, and updating my Adobe post processing software.
