Dear Will.

Apologies for discussing a non halide issue.

I understand that you have recently purchased a scanner and are delving into the digital world to show your results. The photos you posted appear to be in a Photoshop format.

The use of .jpg or JPEG files is more common and will enable more people to see your excellent results.

Keep up your excellent work and posts.

Emulsion.

PS: I am very interested how you achieve 40ASA without the need for sensitisers. Can you post your process if it is non-commercial?
