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.

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 much the same; but usually more space limited in publication, so they are not as in-depth or obsessional as the non-traditional media. The key difference between mainstream reviewers and bloggers is that they don’t actually own the thing they are reviewing. Bloggers usually have used their own money.

So when you read blogs about the latest big thing, in my case recently, the Sigma DP1, you are usually getting the opinion of someone who really, really wants this thing to be good. Even if it is not.

The DP1 looks like a marvel on paper. The (Foveon) sensor is giant-sized amongst its rivals, which means it should be less noisy, and have better dynamic range than most. By all accounts, it seems to. The optics seem reasonable. It is quite a capable camera. People are comparing them to SLRs, and suggesting the DP1 is more like an “affordable” digital rangefinder. The wheels start to wobble when you find out that the focal distance (minimum 16cm) is quite limited and the lens is only f/4.0—especially when compared to rival cameras. Image-wise, it should be better than its rivals, but it doesn’t seem to be significantly better, and new images would suggest that it is amazingly better. But some things are pretty disappointing, like the very slow write times. Up to 12 seconds a shot… perhaps less with a faster card.

But everyone wants it to be good.

Enter Carl Rytterfalk, blogger. You can’t say that he isn’t enthusiastic about the DP1. His posts cover a range of excitement, disappointment, workarounds, and excitement again. Luckily, he is posting informative stuff on the camera… and some entertaining videos (he also blogs about the Sigma SD14, similar sensor but in an SLR body). The nice thing about his reviews are that he is unapologetic in his enthusiasm, but he doesn’t ignore the problems:


Btw, as someone said at the forum already – turning off quick preview makes the DP1 faster between shots. And I also tested a normal SD card that came with another camera – it’s SOOOO SLOW! It really takes ages. So please. Use fastest card you can find, it’s a huge difference!

Timed save times RAW (light blinking):

SanDisk Extreme III 4GB: 2.5s

Canon SD SDC 32MB: 10s

Time before you can take another shot (single mode): 3.8s and quick preview off.

If you look at his site, you’ll see he’s thorough. He even compares it (somewhat tenuously) to the RED Mysterium sensor.

It is also worth considering that so-called “bloggers” could be paid shills for whatever company they are promoting. Ever wondered how some of these guys get their hands on stuff way before everyone else? On the other hand, now that bloggers “get there first” with reviews, you have to wonder at the number of posts that are less to do with reviewing and more about soothing buyers regret. People like Carl Rytterfalk, excepted.

And the camera? Its quirks guarantee it will be a cult hit.

Kubrick — via Bagelturf — shooting in candlelight using a modified Zeiss f/0.7 lens originally intended for spy satellites. I don’t think I saw the f/0.7, but I am pretty sure the f/1 Zeiss he had modified to mount onto a Mitchell camera was at the Kubrick exhibition in the ACMI (Melbourne) last year. There is an extract from American Cinematographer about it at Visual Memory (they also have a trove of additional Stanley Kubrick archives).

Current fast lenses include the Leica Noctilux-M 50mm f/1, VFX Supervisor Tommy Oshima has one… as do quite a few others… current version is $6k USD new. There is also the discontinued Canon EF 50mm f/1.0.

Greyscale Gorilla’s review of Aperture 2.0.

When Aperture 2.0 came out. I was pleasantly surprised to see that apple had dropped the price to $199. Early reviews of the software claimed that the speed issues were also solved, and the the new version was super fast. So far, so good. When I go take a closer look at the specs however, I am astonished to see that Apple Aperture still had no Curves. Thanks right, after all the criticism, Apple still decides to leave out the most flexible color correction tool available. I understand that Aperture is not supposed to be a full replacement for Photoshop. I don’t expect Aperture to have some esoteric Photoshop feature like Gradient Map, or be able to execute complicated layer based photo editing, but I am talking about Curves here.

And the follow-up:

Why did I decide on Aperture over Lightroom? It was the ease of use, and overall feature set that brought be back to Aperture over Lightroom. The full frame mode is GREAT. I can flip through all the images and quickly rate and process the best ones checking for focus. The full RGB levels editor in Aperture is actually MORE flexible than Lightroom’s curves. HOW? The ability to adjust the “quarter pointsâ€� on the levels graph allows one to emulate curves. It’s a little tricky to get used to, but after I figured it out, it all became clear. And, with the ability to adjust the red green and blue separate, I can do 90% of what curves can do.

And a different review going the other way:

I spent a couple of days with it and to be honest couldn’t see anything that would stop me pushing ahead with my migration to Lightroom. Ironically some of the new search options (â€�have adjustmentsâ€�) actually made it easier to manage the data migration. And whilst speed had improved, it still wasn’t snappy in the same way Lightroom is.

It seems to me the number one Aperture plug-in would be a curves tool. Number two would be Noise Ninja (or similar). And if only there was a way to save “looks” like there is in Lightroom, although someone has developed a work-around… (can’t find the link, but basically it was making a library of your favourite photo’s with their preset looks, and lifting and stamping from them – simple, but workable).

200803131020.jpg While I stand in my kitchen, sipping my morning coffee, a couple of junkies outside are locked in the slowest verbal jousting I have ever heard. Each side seems to take a little nap between responses… I hope they finish before noon.

They probably wouldn’t be arguing if only they knew that details of the Canon 5D MkII have been leaked/rumoured/invented at the Digital Photography Review forums (and further comment here). Supposedly there will be an official announcement April 22.

Features (allegedly) include:

  • A new full-frame sensor with fancier noise reduction
  • Weather sealing like the 1D series
  • 15.3 MP
  • ISO 12800 (hmmm)
  • Micro lens fine adjustment
  • EOS Integrated Cleaning System
  • Live View (meh!)
  • 6/3 fps continuous shooting for up to 68 frames
  • MSRP $3499 USD, available June 2

This covers my wishlist, so much so, I am willing to believe. Anyway, it must be true, I read it on an internet chat forum. It does seem like a plausible response to the excellent Nikon D3 – what a happy day for digital SLR-ists.

I think the junkies outside must have heard. Argument finished.
