Couple from a Fourth of July fireworks show.
I like to use an old Fujinon 55mm F1.8 for fireworks as it has a lot of aberrations used wide open on a digital sensor and it produces some stunning images. As you can probably tell I really don’t care too much about realism for these shots, so I left a uv filter on the lens to exaggerate any effects. The red orb shot has the exposure dropped about 2/3 stop and the black level dropped a bit more, slight clarity boost and I think a fairly strong contrast curve if I remember correctly. The other was just a slight exposure drop and black level drop and resized in lightroom.
