I no longer have ACR. I have Affinity with NIK tools as a plugin, which are still available for download. Affinity works somewhat like ACR and PS. It opens up into a basic editor like ACR then you can open the image into a "develop" program and do more work with layers.
I had to increase the black point, reduce the highlights, and increase the contrast and vibrance. I also did some sharpening, hopefully not too much. I am still getting used to the Affinity program.
I opened Silver Efex Pro and did the conversion to black and white. Then I played around some more with it. Using levels and curves. I used a layer mask to take down some of the dark in the dress after making an overall adjustment for her face. I could probably have done another layer mask and brought up the dress some more.
Anyway, It didn't take all that long to do. However, if you want a contrasty grayscale image with black, white and all in-between, it is best to start with an image that would represent that. Then just tweak it to your taste. If not, then you take the chance that the image will likely look way over processed. At least that has been my experience with image processing. I am still learning so this was good practice for me.
I tend to like contrasty images.
Adjusting the black point and/or using the 'dehaze' adjustment will help get you there. I think 'dehaze' works similar to the black point adjustment.
