OK Michelle thanks.Leads me to what counts when making an image in Black&White.I see so many that look very good and wonder what settings they played with to get the best effect. whether it be mid tones or where you concentrate shadows. I have tried then just forget it and go to sepia. I like real grey tones without the blue in them.But still like keeping a lot of depth which is quite the challenge for me.Especially as you say for portraits.Sort of where you feel the colour,but it is in B&W
