    [17:49:56] matt [wronka.org]/Merch Interesingly, where I had service dark areas with the LG/Google Nexus 4, the Nokia N900 has reasonable UMTS reception.

    [21:41:47] matt [wronka.org]/Psi.cor Slightly longer review of the Lytro Illum camera: http://focoro.com/Articles-uwronka/lytro-illum
    [21:42:49] matt [wronka.org]/Psi.cor I'm keen to see if the refocusing does help with street photography. It does help with dogs.

    Lytro Illum: 30 second review
    [08:59:53] matt [wronka.org]/Psi.cor I finally picked-up my Lytro Illum Camera after its shipment delay (due to "technical difficulties at the fulfillment center") and found enough time to write-up my initial impressions after fooling around with it for a short time. Since I haven't really tried to take any real shots with it yet—the camera on paper is about on par for 2-D photographically with a 2001 Canon EOS-1D or a 2003 Nikon D2H. ISO at 2300 looked (subjectively) as good as the 2006 Canon EOS 20D at 1600 as a rough guide at noise control (although the much newer Leica X2 also doesn't like shooting above ISO 1600).
    Lytro Illum: 10 second sofware review
    [08:59:58] matt [wronka.org]/Psi.cor The on-camera software is the part of the Lytro Illum about which I find myself most pleased. There are four programmable buttons (labeled for auto-focus, auto-exposure lock, hyperfocal-distance focus, and a generically labeled "function" button), as well as one non-programmable "Lytro" button which toggles—basically—focus-peeking. Of course focus peeking on a Lytor camera is a bit different, but it's still quite nice. Zooming and focusing rotation direction are both controlled by the same setting toggle which is reasonable.
    Lytro Illum: 10 second hardware review
    [09:00:00] matt [wronka.org]/Psi.cor The hardware has oddly been compared to—if not called—a "DSLR". I guess in this case that stands for "Digital Single Lens Refocusing" camera. It is much larger than I expected, and it is much bigger than my Olympus OM-D E-M5 set-up. It doesn't feel unweildy, though—in fact I'd have preferred a slightly larger body as my right hand does feel a little cramped. I find it natural to handle the camera as if the LCD were a waist-level viewfinder. The camera feels quite natural.
    Lytro Illum: 10 second desktop software review
    [09:00:01] matt [wronka.org]/Psi.cor The desktop software is the oddest bit. It's better than the version 1 of the software I last used. It has basic controls for exposure, and exposes tilt-shift dials (although given the Lytro focus on style and integration, I'd have expected something a little fancier than two sliders to control this—I'm not sure if I should be happy or dissappointed though). While the camera looks like it was designed by photographers, the software looks like it was designed by software developers who hadn't developed raw images. There's no way of selecting a custom grey point either on the camera or in the software, so you're stuck sliding the temperature and tent which is an inexcusable oversight.

    [08:51:47] matt [wronka.org]/Lilith Apparently the camera still hasn't shipped, but the charge had posted five days past.

    Monday, August 11 2014

    [19:05:35] matt [wronka.org]/Lilith According to the eMail Lytro sent me on the first, my Lytro Illum camera should ship today (8th-11th; pending as of noon).
    [19:08:08] matt [wronka.org]/Lilith Looking at the diagrams on the Lytro Web site for the Illum camera, it actually looks quite nice, with both a manual zoom and a manual focus ring.
    [19:10:08] matt [wronka.org]/Lilith The sensor in the Illum camera is a bit smaller than I had expected, approximately the same size (and density!) of that in the Nokia 808 Pureview mobile phone. We'll see how that impacts dynamic range.

    [19:31:18] matt [wronka.org]/Merch U.S. Airways baggage deskm at ORF was very helpful with our lost luggage.
    [19:33:04] matt [wronka.org]/Merch "Don't worry this happens all the time. [Where are you staying?] Oh, yeah, we deliver stuff there all the time."
    [19:35:06] matt [wronka.org]/Merch Despite waiting on the tarmac for 22 minutes, apparently anyone transferring in PHL from BOS didn't get to retrieve bags at the other end.
    [22:33:54] matt [wronka.org]/Merch After calling US Air and getting a Web site to check, we were able to find no additional information. At 21:40, it still only told us that our bag had been acquired, was en route, and had arrived at the airport at 1500.
    [22:35:15] matt [wronka.org]/Merch At 2220, the page had been updated to indicate that our bags would be delivered no later than 8pm.
    [22:36:19] matt [wronka.org]/Merch With poor cell coverage, we also noticed a recent voicemail requesting we return a call. By 2230 we had our bags.

    Ubuntu 13.10 and Darktable
    [10:15:31] matt [wronka.org]/Trip Unfortunately, the Darktable developers package the latest versions for Ubuntu, which means it's simply easiest to use that distro. Installing 13.10 at home at least avoided the issues 13.04 had at work with filesystems not being mounted during init (like /tmp), but oddly switching from 12.10 to 13.10 30-bit dual-head became unstable and lost acceleration. 13.10 seems to work alright (or at lesat with accelration) when connected do one output to the Haswell card, but connecting two leads to instability and a lots of acceleration. The same computer, swaping the boot drive, works fine with dual-head 30-bit on 12.10 so this appears to be a software regression as opposed to a lack of general support for the configuation.

    Otherwise, upgrading to Darktable 1.4 from 1.2.x has been positive. (Back on 12.10), it feels much faster, especially when turning-on level and curve controls (it seems to have already calculated the luminosity distribution which used to take an annoyingly long time to appear), and more controls can be instanced—this is particularly useful for levels to be used like an ND grad (better than the default ND grad control) and spot removal which can now blend to just affect spots when cloning dust.
