Does anyone know what I'm talking about? That red vertical lens flare/flash you see in videos? I would like to know who to manipulate this into photos. Here's an example of it, it's a short minute and a half clip from the snowboard film Pop. http://www.youtube.com​/watch?v=LPG5K1CypU0 (external link)
Do you think they add it in in post production or is that just typical lens flare? And how could i create something like that in photos?

i doubt that was added in PP...more to do with the sun and it's angle, i'd guess...

looks like an effect simulating 16mm film at the end of the roll
edit, maybe not the one i was thinking of but still looks like "fogging" of the roll
try searching for that

Are you talking about the reddish tone that the vertical edges of the image take in some portions of the video?

I made a gradient:

IMAGE: http://kirkt.smugmug.com/Photography/Photo-of-the-Day/gradient/711286205_e2nNS-XL.jpg

and dragged across the image on a new layer to overlay the gradient on the image. I set the gradient's layer to "screen" and adjusted the opacity to about 65% - play with the blend mode and opacity to get the interaction between the gradient and the image. I also created a mask for the gradient layer so that the layer was masked in the middle 3/5 and transitioned to full opacity on the edges. I played around with distorting the gradient by using the "Filters>Distort>Lens Correction" and making the gradient bulge with some barrel distortion - you can also mess with the vignetting in this dialog to break up the uniformity of the gradient.

Here's the random image I used for this test

I got:

Hope this helps, I am sure there are a million and one ways to do this.

I think Kirk is definitely headed in the right direction!!
I also think that in the video, the flare-ish things were added in PP.

kirk thanks for the little tutorial. i gave it a try but had a little difficultly make the custom gradient in gimp...couldn't get the two colors merging on each end into transparent...i'll keep pluggin away at it though...and i agree kyle, i think the flare in the video i posted is done in PP

^^^ This ^^^

It's meant to simulate an effect seen on film.

You can always film a candle and then overlay that on the video and throw some effects in.

Agree. Looks like what you get when a film isn't handled properly and exposed to light.
Looks like it's added in post here. Not too hard.

Kirk gave a good example. You might want to try some different blend modes (soft light, overlay)

The rick you see is a combo of two things. One called "flicking the gate" This is where the camera operator flicks the opening, called the gate, around the shutter block where the film runs between the lens and camera. That is the Flash, usually of white, you are seeing the red could be from the way the light affects the film. Coupled with this is the start up time of the camera. as the operator keys the camera the film does not always run at a perfect speed, this can also lend a hand to this effect. As for doing it in a photo i would use te tutorial above, tho it may not feel the same as what you see is in a moving picture and you are dealing with stills. The motion is what really brings this feeling to life. Hope it hels.


First step........ Take the lens cap off.
