I have a friend who has a good body of work, spanning quite a few years, in her black and white child photography portfolio. She has a recognizable style, and her customers hire her based on that style.
She depends on labs to print her work. When she started, she shot on film, and there were good commercial printers available that would print at a reasonable cost. Then, the reasonable cost commercial printers transitioned to a lightjet workflow, so she transitioned to a film plus quality lab scans plus digital post workflow. The lab quality scans then became more problematic, so she made the decision to move to a digital capture and Silver FX workflow, with lightjet printing.
The emulation software has enabled her to maintain consistency of style while adapting to the changing realities in commercial labs.
