Try a contrast ratio somewhat less than 10,000,000:1.


Form,

The atomic fire shining through the window is probably somewhere around 'Sunny 16.'
At ISO 800 and f/3.2, it is ~8 stops overexposed. Zone 13 or so. Not quite Edgerton territory, but getting there.
Immediately bordering this photonic blast, you have some dude wearing a dark suit. Add a few more stops to the local contrast ratio.

And you wonder why you're getting a bit of flare and scattering?
No commercially viable anti-reflective coatings will suffice under these conditions.
