Blowing dust

A smattering dust can really ruin a good scan. Watching the local film processing guy drop your neg on his putrid floor (imbecile!) can raise your blood pressure faster than you can say C41!

So I’ve been having problems with little smatterings of dust on most of my scans. And the scanner I use doesn’t have Digital ICE (it’s an old Minolta - keepin’ it real). After using a few of the available software-based anti-dust systems out there, I remained unconvinced. On the discussion boards, people were saying to do it by hand. For bigger bits, sure, but a billion tiny grains…?

I decided it was simple to do better. I wrote (in the loosest sense) a Photoshop action which reduces dust, but doesn’t remove all the grain from the photo.

It is does all this with a difference matte made from the original (dusty) image, and a version that has been run through the Photoshop Dust & Scratches filter. Old school like.

It aint fancy.

But it is fast and reliable. Also, it doesn’t get rid of all the dust (yep, paint it). But will remove all that cocaine you chopped up on your negatives the night before… Or if you are more like me, the baby powder that they seem to sprinkle all my negs with when they leave the lab.

See? The grain (mostly) survives. All that the matte is doing is revealing back to to D&S version of the image. Visually, it looks ok, and has probably saved me about a lifetime of manual healing brush time. Now you can get out there and shoot — post production is for the birds!

I make no guarantees this will work with your stuff. But have a go, it might.

Cameron on dimension…

There is a great interview in Variety with James Cameron and his perspective on 3D films (pun intended). Of course, what he says is quite convincing, and salient. I met him once. He made some convincingly salient points then too. Via Daring Fireball, via John August.

Lovely

It is always interesting when you take a diversion from concentrating on "visual effects" and go see what other people are doing with graphics technology. In many ways, the SIGGRAPH conference is a yearly fix of all things interesting, but you have to stop working to get there, and residing ...

The age of the plenoptic lens, etc.

May we all see like insects: light fields and plenoptic lenses. There could well be an interesting shift in specialised photography where extracting 3D data from digital images shot with either special lenses or sensors (and with a lot of post-processing/number crunching) become useful tools for VFX practitioners. (Full disclosure: ...

The truth and the chaff

It is interesting when you are scouring on the web for the newest thing™—be it the RED camera, or anything else—that so many reviews are now done by new owners writing on their own blogs. Some of them write excellent appraisals, some of them don't. "Traditional media" reviews can be ...

Pixar’s pixel people parley…

This is a very interesting (100 minute!) panel discussion featuring various computer graphics industry legends (details below), who pretty much have the Bay Area and Pixar in common... anyway, this is not a super-tech, jargon-filled discussion – rather it is more like an oral history of computer graphics. ...

Firefox 3 beta and broken site…

This site was horribly broken under Firefox 3 Beta, but I think I have fixed that now... I have no idea why, or how, but suspect that voodoo and some incantations helped greatly. Chicken blood never worked so well. I also suspect that a new layout/theme helped greatly too...

Muxtape

I can't remember where I saw the link to this... but it is a great way to share mix-tapes. Something to listen to when you are hard at work creating images: Muxtape. Created by photographer, Justin Ouellette or Chromogenic, who is in my flickr stream... maybe that's where I saw ...
