Lollygagging around this area the other afternoon…
Protip to one or two dopes in the comments sections of my favorite Kansas City blogger Tony’s Kansas City that there’s no special “star filter” for when the sun shines like this, it’s shooting with a narrow aperture (this was at f/16). When it’s that narrow the lens aperture blades refract the light in the same shape of the aperture onto the sensor (or film). You’re my community service for the day.
Next…
This was an f/10 aperture; you’ll notice the “starburst” look isn’t as pronounced now with a wider aperture and more protons flying through the wider aperture and onto the sensor.
^Did a symmetrical photoshop hoo-haa with it.
