Personally, I have rarely if ever noticed any diffraction issues with my own images. What lens were you using that goes to f/45? I have film 4x5" View Camera lenses that go to f/45 or f/64, but for my 35mm film and digital cameras only macro lenses to f/32.

While looking for a tool I had mislaid I found this rock, with nothing else to do I shot a few images.
All three images are focus stacked, images 2#3 have 3mm an led inserted in a hole in the foam core back ground.
Last year I was doing a project where I need colored leds, I ended up with a lifetime supply of leds!!

You always find something interesting to share Frank!
