What happens when you twist your lens' focus ring while shooting long exposures of fireworks

#photography

It's an imperfect technique; it requires a lot of trail and error (and twisting). For ever 20 frames you might get a good one if you're aimed in the right place. I find the most interesting images come from starting out-of-focus. Also shoot with a wide aperture for big bokeh.
@Nick_ulivieri “trail and error” I see what you did there
@Nick_ulivieri i like that picture a lot!
i did something a bit similar to add a halo bloomish effect onto a handheld tele long exposure that i was doing. the focus pull hides the shakiness somewhat.

@Nick_ulivieri A happy accident!
@Fernhead It was very deliberate. I basically shot an entire 4th of July neigborhood fireworks show using this technique. Lots of reject frames for sure, but a few were really stellar
@Nick_ulivieri well the results are stellar.
@Fernhead Thanks! If you've taken enough 'normal' firework photos, this is a fun way to shake things up
@Nick_ulivieri Was never curious about that until I saw this.
@Nick_ulivieri WOW 🤩 what an amazing shot!!

@Nick_ulivieri Twisting the focus? Or the zoom? Is this on it's side?

Having trouble figuring how this works. Is this one very out of focus, and then comes more into focus later in the shot (hence narrowing of the bokeh?)

@naught101 not the zoom, only the focus. And you’re right. This starts out or focus and comes into focus (nearly) at the end of the exposure. That’s they the bokekntightens up as the exploding embers expand outwards.

@Nick_ulivieri @naught101 I did it with zoom and broke a lens!

Love what you've achieved here!

@Nick_ulivieri

This might explain what goes on in the optic nerve on LSD.

@Nick_ulivieri That's very cool. I do love a great photo. :-)
@Nick_ulivieri Wow, beautiful! I don‘t dare to ask how many shots you missed until this beauty appeared.
Given the shapes I guess you had to start defocused and then just hit the spot while fireworks were flying, right? Incredible.
@tanuva Maybe 1 of 15 hits with something interesting. I was shooting neighborhood fireworks in the city on the 4th, so I had a couple hours. But, yes, I start defocused and rigged up a little focus index 'stopper' with a couple paper clips at ∞ so I'd end the exposure as focused as I could get given the situation
@tanuva The challenge was always knowing where the fireworks were coming from. I had an 180° views and they were coming from all over. Some people were more active but then would rest and another group would start firing. Half the battle was getting the camera pointed in the right direction as I head the 'thud' of the mortar fire from its tube
@Nick_ulivieri @tanuva
I thought there must be some sort of tactile marker for "target". Also guessing this is a manual/mechanical focus ring, rather than the "focus adjustment" rings you get on fully electronic lenses.
@Nick_ulivieri Ohhh...I wonder if the makers know/knew this?
@Nick_ulivieri Well, the Japanese word for fireworks, hanabi, literally translates as “flower-fire". Spot on.

@simone__marini @Nick_ulivieri

very cool photo!! 😍

similar in chinese! i am nowhere near fluent in mandarin but did happen to learn recently how to say 'fireworks' which translates literally to 'smoke flowers' 煙花 (had to look up the characters just now 😅) and in looking those up, i've now learned that firework (singular) is 'blazing fire' 焰火 💥 languages are fun 😊

@CuratorOfCosmicDust @simone__marini Thanks for sharing! This is an interesting tidbit!
@Nick_ulivieri Wow. Just wow! That is brilliant.
@Nick_ulivieri this is so gorgeous. Do you have a version of this/similar photos available as a wallpaper?
This looks awesome!
@Nick_ulivieri ok yeah that's fukn cool
@Nick_ulivieri HOLY SHIT that's mindblowingly beautiful and ingenious.
@Nick_ulivieri This is absolutely beautiful.
@Nick_ulivieri fantastic! How do you move the rocus ring without introducing motion blur?
@constantgeekery A sturdy tripod helps, but you don’t, really. If you look close you can see some slight serpentine wobbles in the ‘jets’ as the expand outwards. Adds a little interest.
@Nick_ulivieri beautifully done! 👏 ❤️

@Nick_ulivieri

Beautiful!

I've often twisted teh zoom ring, but not the focus...

@Nick_ulivieri I used to do this with sports action shots. It was tricky to keep the center area in focus, but when it worked, it was a great effect. The shorter exposures made the zoom blur a bit shorter and gave a tunnel effect to the action.
@Nick_ulivieri Looks like generative art

@flintpope @Nick_ulivieri it is: art generated by a human experimenting with an artistic instrument.

what you might be referring to is actually "derivative imagery": images derivated by large language models from millions of works of art generated by humans who did not consent to that processing and derivation.
