1. I definitely meant dramatic monochrome version of the color image.
2. following your logic, why should we postprocess images at all? Let me submit raw files instead and there are plenty of photo-editing software and plugins, that buyer may use.
Whenever I want to submit BW, it’s not because it’s better,
It’s because (at least in my opinion) it’s significantly different and average buyer won’t easily visualize this. That why additional format isn’t particularly useful option in this case
What harm is it going to cause if you have some monochrome versions along with color, as long as particular portfolio has reasonably low % of? posted in Duplicates - soon to be removed
