use a single coated lens instead of multi coated

the single coated flashes the shadows that would otherwise be clear so a little more detail appears

and

a post bath of borax

this will improve the shadows a little and is easy

if you mix up the D76 yourself alter to the Adox Borax MQ formula or ID68, D76 is too general purpose, a set of micro scales is cheap.
