  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

I'm going through some footage that I'm shooting and in one shot there is a single frame of what looks like gate flare to me. It flashes once and then is gone.

I'm asking you guys what it could be, not because I want to prevent it, but because I like it and want to control it :)
Any ideas how this happened? My only thought is that since I had a handful of bottle caps one caught the light just right to throw this on the frame. Should I look into developing a bottlecap gobo to repeat it or could it be something else?

The reason I'm not sure of that is this is much wider than every instance of gate flare I've seen:

Brian: Yeah, it's liquid shot through glass. I'm about 2.5 feet away.

EDIT: I have the bushing, just haven't installed it yet. I working up the nerves to mess around so close to my sensor :)

That's because, at 2K, it'll look wider.

He shot in 5K.

Liquids can spread a flare or a beam of light.

Not sure though since its just one flash frame....

It does like look gate flare, maybe in this case caused by reflection off the bottle caps. Most commonly the source is a hard light source out of frame, but reflections work as well if their exposure level is high enough. In a setup similar to your sample, you could try hitting the caps with hard front light above frame so they bounce light back onto the lens as they spin and drop.

Yup 5K. Hopefully it's not the liquid spreading the flare - that'll be hard to replicate :/ Guess I'll have to make time for some tests this week.

The gate flare will be as wide as the light source. Because it's not optical (it's a reflection off a flat surface) the gate flare can be as wide as the whole frame if the light source producing it is that wide. (When it's that wide, it looks a bit like flashed film.) I've seen it be very wide when coming from a window in an interior shoot.

If I were to guess, I'd suspect a reflection off the surface of the liquid, just out of frame.

It's not that big of deal, very easy process. One tip that I've seen Mark Toia mention, and I do it myself every time I change lens mounts or mess around with the camera in a way that something could fall onto the sensor, is to not allow such an opportunity. mount the camera on a tripod head or other means where it can be tipped forward. If anything happens to drop, it will fall away from the sensor.

A flashed film look is something I hadn't thought of using a flare for. Could be useful, thanks :)

Good thinking. I guess I need to get over it, considering I wanted the self-installed bushing so I can go back and forth as wanted/needed. Thanks for the tip!
