A couple of days ago Trena posted an mono abstract of an Agave (attached)At first I wasn't sure that B&W works for plant shot, but then I though it might be a good candidate for split toning. So with Trena's permission I've had a play.
So what is split toning? Split toning is an old film effect where the image comes out somewhere between black & white and colour. Often, when film photographers decided to use sepia toning, they found their image to have not completely bleached and this left a multi toned style image which was given the name split toning - typically with a cool/blue tone in the shadows & warm/sepia tone in the highlights (example attached) . With the digital darkroom you're not limited in the colours you choose
As in all things digital there are many ways of split toning & I've spent the morning having a play with some of the options which I'll write up in the following posts
