laptop screen effect

Postby SJCorrectet » Mon Oct 12, 2009 5:23 pm

Been thinking about this for a while,

What visual effect sequence could you use to replicate the experience of having your laptop screen tilted too far backwards, when you're looking at it from too far below, and the contrast goes out and darker colors start to become vaguely vibrant, etc?

I realized the iTunes visualizer becomes significantly more visually paletteable when viewed from a low angle, and I'm bothered that I can't pinpoint exactly what's going on.

Thanks

Oddly enough, I think you can just fiddle with the brightness and contrast >_>

I don't think that it would take much more than tweaking the brightness and contrast, and if you're using vegas, phosphorescence in "tv simulator" will give you a more realistic screen effect. And use 3d to make it look more like a tilted panel if you'd like :up:

the thing is, I've played with the brightness and contrast and it doesn't quite capture it.

On a tilted screen, pure black becomes almost luminous, and colors darken but also blend and integrate.

I've vaguely approximated it in premiere by darkening and raising the contrast, followed by a luminosity invert blended with the original so that only around 20 percent is inverted. This I followed up with a large dose of unsharp mask. The luminosity invert and unsharp mask really pushed it closer to what I'm looking for, but it was still pretty far off the mark.

I'm not so much simulating a laptop screen as I'm trying to replicate the visual effect produced by an LCD screen when viewed from a low angle.

but yeah, tilting the image back would go straight to the heart of the matter I suppose. haha. :up:

Use "color curves" and raise the lower control point a little bit to stop it up. You cal also try just doing it with a single color like blue if you want a slight tint.

oh alright, straight up.

That's a good method, comes a lot closer
