Long time lurker ... first time poster.
Shot with orig Q + 01 w/ Bold Monochrome Smart Effect.
The light source from the top right corner is actually a horrible flare ... as I don't have a hood on the 01 (yet). The Bold Monochrome Smart Effects salvaged this shot.
This effect could have been done via post, but I may have very well missed that opportunity with this shot (might have dismissed this as a bad capture and either threw it on storage and ignored ... or worse, deleted).
And here is another (pet portrait) with same Q and lens as above ... with Blur Control + post effect in DxO FilmPack5
