He does give some context? Skimmed the video yesterday and won’t go looking for timestamps but he did mention that those monitor specs allow you to simulate the viewing of large prints at what he considers appropriate viewing distance. Wasn’t there also a mention of proofing/evaluating sharpening at 50% zoom with the aforementioned monitor setup?
edit: wow almost deleted the comment but managed to get it back…
Now that I’m here I have to say his images are really not my cup of tea. Far into the realms of kitch.
