Dante Stella on the Leica M8:

At the end of the day, photography is about life more than anything else. It’s about capturing things that cannot be later reproduced. A good camera is one that you never think about. It is in your pocket when you need it to be. And good photograph is one that you enjoy twenty years from now.

I’m on record as saying I’m going to wait on buying an M8. I have three systems I’m working with for now:

1. Nikon D80 with the 24mm f/2.8 (supplemented by the 50mm, 12-24mm)
2. Nikon P5000 Coolpix at high iso in black and white
3. Leica M6ttl with 50mm or 35mm Summicron with C-41 film scanned with National Photo’s (Reisterstown Rd, Baltimore, MD) Noritsu scanner.

I’ve run the economic numbers many times and so does Dante: Dante’s calculation for me is about right- the Leica costs me about $20 a roll all said with film and developing costs. His estimate of 60% depreciation of the M8 over 3 years is realistic looking at the prices of 3 year old high end Nikons. Buy a US$5000 camera today, resell at US$2000 in 3 years- cost $1000 a year. 50 rolls of film.
I think that if I didn’t have the convenient film workflow, I’d be more inclined to use digital capture. But I like the imposition of non-linear chemical sensitivity in the workflow for it’s transformative capabilities. The M8 is a very accurate painter of the scene. Film stretches and compresses by itself. The transformation to black and white, out of my control, is another step away from the scene as presented. Even the wait to develop and view provides more distance.

There’s a pleasure in the unexpected transformation of film photography that is different from the immediacy of digital. For learning how to expose and light, digital is far superior. It is immediate and predictable. For me there is then a journey to transform the image to create the personal vision. My experience with film is different, it is one of experience and discovery.

I remember the day well.

I wanted to try out Zillow, but it would only run on IE or Firefox, not Safari. I downloaded Firefox, tried it out and never looked back.

Best was using the same browser on my Macs and the corporate laptop. With the Safari for Windows, I thought I’d try Safari again, since I could duplicate the browser experience across platforms once again.It seems the experiment is over and I’m back to Firefox.

The reasons?
1. The web editor for WordPress is flaky in Safari, rock solid in Firefox.
2. While both browsers auto detect feeds, only Firefox allows direct subscription in Google Reader, by current reader of choice (sorry Brett!)
3. OS X antialiased font rendering is great on the Mac. On Windows, it makes Safari look fuzzy. I saw it immediately.
4. Safari spawns new windows even when I tell it not to. Firefox obediently opens new tabs and rarely overwrites a page that I want to keep open
5. Both browsers are equally prone to memory leaks and have to be shut down prior to using memory intensive programs like Photoshop. Safari failed to provide any gain.
6. The bookmark sidebar in Firefox allows for rapid scanning of pages for new content within a window, especially on a large monitor. Safari only displays bookmarks in the main content window.
7. There are nice EXIF browser plugins for Firefox that let me see what camera David Allen Harvey is using today (D200, D70s or M8?). No such plugins for Safari.
8. Both browsers allow tabs to be reordered. Only Firefox allows dragging a tab into another window. It’s one of my organizing methods when I doing extensive research on the web.
9. Only Firefox has find as you type in the toolbar search box. It’s usefulness borders on the uncanny.

I couldn’t think of 10. Really.

I keep coming back to Safari for one reason. On the Mac, there is the new Inspector for webkit.  It allows you to browse styles while displaying the page. Select text and the synthesized CSS style is shown. Since I’m now engaged in understanding CSS for the first time, this is a very useful learning and troubleshooting tool.

tech ronin: To iPhone or Not?

The painful memories of looking forward to and being disappointed by the first Newton still affect my thinking on whether or not to get in line and buy an iPhone next week. I am an optimist and a technology enthusiast.

I know the feeling. I’ll never forget sitting in my car and staring at the Newton MessagePad screen that was almost unreadable in daylight. Some how I got used to it and perservered with my Newton for several years before switching over to the much more practical Palm Pilot.

Now I carry a Blackberry, required because of corporate mail. It’s a decent phone and a really good mobile email system. It has a tiny screen and can’t display attachments like my last Palm could, so I always need to travel with a laptop to read attached documents. It works as an EVDO modem with my corporate laptop (not my Powerbook). The calendar function works fine, syncing with the corporate Exchange calendar well enough. I’ve never been able to use it for note taking or mobile text database the way I did with the Palm. I blame this on it’s Outlook style Notes and Tasks which just don’t work for me. I use the Web browser for Weather Underground and Google Reader almost exclusively as they provide a pretty good mobile experience.

It’s on Verizon, so in Europe it needs to be synced from the laptop. I’d like to believe that I could switch to the iPhone, get global GSM, usable browsing, calendaring and note taking but I just don’t think the corporate integration will be their. I’d have to carry both the largish iPhone and the large Blackberry. I imagine that I could use the web access to corporate email, but I doubt I’ll get usable email and calendar integration. We use Blackberry. Otherwise you’re on your own. Like the iPod and Apple TV at their introductions, they will useful gadgets, but probably will take some time before they gain enough traction to force general integration.

If ever. I’m on the sidelines for this one. For now.

On Deciding . . . Better : Imagination as Simulation

Simple solutions to complex problems are usually wrong. Complex problems usually require complex solutions. In a complex situation it can be hard to know which variables are important. We tend to act from simple biases based on simple analogies once complexity becomes too great.

When decisions involve uncertainty, multiple goals and multiple effects technology can help amplify imagination. In my own life, I’ve been exploring how this technology can help me clarify my goals, understand my assumptions and help me act in a way that is most consistent with what I believe.

With my effort to set ODB 3.0 up on a new server, I was feeling a bit nostalgic. Via the Wayback machine, this was my first ever posting to ODB 1.0. My beard was black and there’s an energy in the writing that I now find admirable. I was learning about new domains of knowlege in Decision Theory. Having digested and incorporated them, I’m on to new challenges.

These days I find myself wondering about the border between awareness and . . . well whatever we’ll call the behaviors generated by the brain that we are not aware of as conscious experience.

If you believe it, the woman who posted this photograph on Flickr found, on Flickr, the photo that was taken simultaneously by the photographer depicted in the photograph. Two photographs taken independently posted and linked on Flickr.

Collusion? Conceptual art? Coincidence? You decide.

Statistical Modeling, Causal Inference, and Social Science: The backseat driver principle

The driver overestimates his control over the situation (including his own car as well as others on the road). The backseat driver (“Whoa–you’re taking that curve too fast!”) underestimates the driver’s control. As a driver, I listen to the passengers because they provide a useful corrective. Even if the backseat driver is sometimes annoying, it makes sense to listen.

My principle: There is no learning without feedback. Be open to every bit of advice, criticism and praise you receive. Evaluate it, but don’t automatically believe it.

This is image is for everyone who says that colors in Nikon D80 images don’t “pop”. I spent some time putting some of the Italy photos through the standard postprocessing for the first time. I had been hoping to have my new Macbook Pro by now, but it may still be “4-6 weeks” for delivery.

In order to get the look I want, images like this need to go through Photoshop where I can control curves and local contrast/luminance as I wish. I’ve been converting from RAW in Capture One, but I may give Nikon’s Capture NX another try once I have the new laptop.

Dave Rogers atGroundhog Day:

Image noise seems to be the “crippling defect” in most compact digital cameras. I guess it comes down to how “seriously” you view the hobby. Small sensors enable smaller cameras, which are easier to carry around and afford some very compact “super-zoom” telephoto lenses. But, the images often contain noise. I know what noise is, I can see it in an image, but honestly, the only reason I think it’s “bad” is because everybody tells me so! I mean, I understand why it’s undesirable, but frankly, I’m still just a little bit amazed we can even do the kinds of things we’re able to do with affordable compact digital cameras these days. So I kind of struggle with it. I read the photography sites because I want to learn what the more experienced people know, but then I have to listen to all the criticism of “noise” and then I start to feel as though I need a better camera. And I have a few. (Four, at the moment.)

Dave knows he’s being led by the Have crowd to believe that his compact cameras are “crippled”. You can do a lot with them, which is not to say that more amazing cameras aren’t in the pipeline. I think Daves right to use what he has and work on being a better picture taker.

Economist.com: :RNA | Really New Advances

All that was worked out decades ago. Since then, RNA has been more or less neglected as a humble carrier of messages and fetcher of building materials. This account of the cell was so satisfying to biologists that few bothered to look beyond it. But they are looking now. For, suddenly, cells seem to be full of RNA doing who-knows-what.

Another cellular signaling system is emerging based on observations of microRNA transcription. Another layer in the onion of biology.
Many years ago, as the complexity of intracellular signaling based on G-Protein coupled receptors, PI and cyclic nucleotides was being described, I wrote in a book chapter that it was as if the network complexity that exists in the neuroanatomy of brain was being mirrored inside each neuron, with branching, cross-talking, diverging and converging pathways. I’m no longer surprised, as this is the nature of complex systems and their networks.
My more recent insight is that the really interesting behavior of all of these complex systems is emergent, meaning that it can’t be deduced no matter how well one understands the behavior of the individual components and their behavior. It’s not hopeless as one does not have to know how aspirin works in order to use it. You have to know when and where to look for the effects, which is where knowledge of mechanism provides leverage for system knowledge at a higher level.

Reality Check.
Since I’ve seen so many images taken with compact digitals in black and white, I thought I should check to be sure that the expense and hassle of running C-41 process black and white film through a Leica was really worth while.I spent just 15 minutes this evening with the Nikon Coolpix P5000 capturing images at high ISO (800 or 1600) with the camera set to capture monochrome JPEGs.This is probably the best of the lot. Since I’m the photographer, it’s not surprising that it looks not very different from what I would have made with any other camera. It’s hard to tell from the small image on Flickr, but it’s clear that it lacks the tonal range of one of the Noritsu scans of the black and white chromogenic films. Film has extended tonal range built into it because of the chemistry and it’s sensitivity to light. The small sensor is short and clipped by comparison.On the other hand, the P5000 allows all the control one needs and vibration reduction as well. With the slower lens, I can handhold the M6 for the same EV as the slower lens in the Coolpix if it’s not at its widest setting (and thus at maximum aperture).
