Flash Jello

Though it makes perfect sense, I was surprised to see this particular rolling shutter effect. This is a still taken from video shot with the T2i. Somebody else uses a flash camera, and of course the rolling shutter only picks up a portion of the flash. This particular still is not unusual or distinct; same damn thing happened over and over.

Yup! I shoot a lot of live music events and when the lights start strobing it goes nuts. Slowing the shutter speed down helps sometimes, even down to 1/30. Then it's nore likely the whole frame is flashed than a part of it.

That's why you see all those "no flash photography" signs at live video events.

If it bugs you, in post you can flash the entire frame 86
85-100% white, the next frame like 35-50% white then nothing on the third frame. It will feel more like what our eyes see. Bright white that blinds us and then out eyes quickly adjust back. I usually leave it alone though.

Yup, it'll happen every time with an electronic flash. When I want a flash like that I have a whole bunch of antique single use flashbulbs which have a longer decaytime and will fill the sensor without this rolling effect. Not always the best logisitical choice (sometimes gotta live with the electronic flash), but for certain gags they work wonders.
