Vdub Filters and over exposure of sun in film

The blue spots are "flare" from shooting towards the sun without a lens hood to keep the glass of your lens in the shade. As the scene moves, you'll probably notice that the flares move too, across the frame. If your camera was on a tripod, and the flares don't move, then you might be able to reduce or eliminate them, though leaving artifacts, by using something like a delogo filter in VirtualDub.

no suggestion

As was pointed out, a delogo type filter might work, if the relative position in the frame is pretty constant, however you will probably just replace it with a blurry section instead. There is no easy or convincing way to eliminate the problem you have.

i like lens flare myself...i always point my cam right at the sun...which the manual says never to do.

[Lileman]

hmm

[zoobie]

Actually, when lens flare happened in old Hollywood productions, they considered the scene ruined.
ha ha!

Try the MSU filters, but don't expect much.

That guy in the shot must be very tall...
All I can see on my monitor is his feet.

SirScrub124,

[Shrink Mode] Where are you in this? Have you accepted that you near totally screwed the shoot and are now ready to hear about salvage? [/Shink Mode]

First hint. You need to shield sun flair out of the shot. Second, stop down sky with ND filters even if you need to heavily light the subject.

This looks like a consumer level camcorder. Next step up has ND filter wheels and a luma knee to keep sky from dominating.

Not to say a consumer camera can't do the job with proper exposure control. It takes more skill to make a consumer camera work to pro standards.

thanks

Do you want to improve your technique or defend your amateur assumptions?

The last one was too boring for words. Did you link the first above?

[Lileman]

thanks

i dont think i screwed it up, it 1 of many perspectives. it actually looks great with the different filters i added. Is it amateur, yes but im damn proud of it. When its all done ill let everyone comment but what you have seen is before any of the filters are added. wait and see...could it have been done better, yeah, could i have bought a better cam, yeap but i lack the funding. I have another film, http://www.youtube.com/watch?v=DJ0d04GTaRI
done with a cam from 1992

The last hour before dawn? I must be playing the video backwards because the sun is going down not rising. The last hour before dawn.... wouldn't the sun be coming up?

I agree with edDV. lol

Good luck.

no longer need the help and outdated information

[zoobie]

steadycams are cool
keep working with it and let us know how it turned out


PS - I'm on dialup and left the comp d/l'ing your video. I came back 15 minutes later and it was still on the sun...and now it's going the wrong way...I'm like...wtf?!

[Scorpion King]

ok, i watched the whole thing and I still don't like it. I don't understand it either.

He takes drugs. He gets drunk. He watched TV... then blows his head off in the shower....

I don't get it.

...to explain a bit more, the camera wasn't pointed directly at the sun. true i shot in the direction but not directly pointing at the sun. Look at the picture.

I am looking at the picture. It wasn't "centered" like a bulls-eye on the sun, but it was pointed at the sun. To get flare, you have to be within a few degrees (I'm guessing up to ~45° off of dead on) to have the lens' optics catch the glare and BEND it into the imager. BTW, it's the reflections of the different optical pieces/boundaries that makes the flare's glow have "echos".
That's why there are lens hoods. You can even make one up yourself cheaply.
Nonetheless, it's better (and more professional) to be able to understand what's going to happen in the shot (before it gets shot), and be able to decide whether a particular outcome is in line with your artistic vision--or whether you need to do some feats of engineering to avoid problems with the shot so your artistic vision doesn't get messed up, THAN it is to just shoot something and look at it later and try to figure out how to fix something you weren't expecting.
This is regardless of whether you like it or not (sometimes I like flare, sometimes I don't).
