I'd like to send a variety of versions of the same image to a lab to look at differences in stock, contrast and sharpening. I know I'll be able to tell the difference in stock by the information on the back of the print, but I need a way to tell the difference between a number of quite subtle variations in image on the same stock.
As these images are for my own testing purposes alone, the most useful way I can think of would be to have the name of the image added in text to each Virtual Copy as a watermark. So Ideally each image would have a watermark made up of:
{image name} {copy name}
Looking at Lightroom CC's watermarking features, I can't see a way to dynamically generate the text from the Virtual Copy's filename and copy name.
What is the best way for me to achieve this?
