The image just above is my template or aesthetic target for new portrait images I'm working on these days. I'm referencing things like the skin tone and the range of all tones; from white to black. So much depends on the lighting. So I'm working on that as well.
My current portrait system is a FujiFilm XT3 and the 60mm f2.4 macro lens. But it's the lighting and the post processing that will make or break the image creation.
I guess I'd better get used to working with the cameras and lenses I already have in house as I just read on DPReview that Canon's CEO is currently predicting an upcoming Photography Apocalypse that will result in no future non-phone cameras to ever be made again after the first day of 2020.
