Shot from the Marin headlands, the Golden Gate Overlook and near Fort Point. I used an RX10 IV with an ND3.0 filter. Raw images were captured every four seconds with a one second exposure time. Edited with LRTimelapse and scored with Filmstro Pro.
I was expecting a pretty sunny day but ended up with regular showers and some pretty wild swings between sunshine and cold soggy overcast weather. I think the occasional raindrop and the mood swings work quite well, although the wind caused a bit of wobble on the long zoom onto the deck of the bridge.

Shadow Captain (Revenger, #2) by Alastair Reynolds
5/5
Excellent sequel to 2016's Revenger. If you tried to sell this series to me - runaway sisters become fearsome space pirates while trying to figure out various mysteries about the rise and fall of a far future civilization and some truly funky currency - I'd put them someone pretty far down my to do list. But in Alastair Reynolds' hands it's a space opera masterpiece. Can't wait for the next installment.
Thomas Friedman in the New York Times today: "Could we have our first four-party election in 2020 — with candidates from the Donald Trump far right, the old G.O.P. center right, the Joe Biden center left and the Alexandria Ocasio-Cortez far left all squaring off, as the deepening divides within our two big parties simply can’t be papered over any longer?". Here's my daisyworld analogy from 2010, and a write-up of an Intelligence Squared debate on the same topic from 2011.
Material Design brought bland consistency to the Android ecosystem. Every app had some sort of bold header and a floating action button. There is some value in consistency and at least some personality was retained. It's red, it's probably Gmail. Yellow, I must be in Keep. Boring but tolerable.
Material Design 2 solves mainly for the problem of knowing which app you're looking at. Colors have gone. Every Google app is now an oppressive black list with some oppressive black icons. To add to the misery the icons have a shade of stock-library amateurism and are just a little too heavy. Unless I look really closely or the what-icon-did-I-just-click region of my brain is on top form there is no longer any way to tell the difference between Google apps.
I'm pretty sure Material Design 3 is just going to be a command prompt. What Android customers really want is telnet or wget and some raw JSON.
A short but steep 2.2 mile loop in San Pedro Valley Park. From the parking lot go behind the toilet block and turn right to find the start of Montara Mountain Trail. After 1.2 miles winding slowly up you reach the junction with Brooks Creek Trail at a bench with views to the Pacific. Take Brooks Creek Trail down 1 mile to the parking lot, passing another bench with a view of the waterfall on the way down.

I have a 58mm ND5 filter that I bought to photograph the 2017 solar eclipse. It worked pretty well for that with my Sony RX100 V, but now I want to use it with an RX10 IV (which has the advantage of a 600mm equivalent zoom). The RX10 accepts 72mm filters and I want to try and photograph an ISS transit which is happening sooner than I can get hold of an adapter.
I figured someone must have done this before, but I can't find a file anywhere. It's a reasonably straightforward part - as the filter is smaller than the thread on the camera I just need a small cylinder which has a 72mm thread on the outside and 58mm on the inside. A step up adapter would be slightly more complicated to accommodate the larger filter size.
To build this I used OpenSCAD and this thread module. Open the thread module file in OpenSCAD and then you just need to subtract the inner thread from the outer thread like this:
This makes a simple 10mm tall adapter and you would just need to change the thread sizes to make it work for pretty much any combination of camera and filter (most filter sizes use a 0.75mm pitch as shown above). The vignetting is pretty extreme with the smaller filter and the size of the adapter. For this application I don't care, I'm only using the center of the image. If it's a problem for your application then it might be worth reducing the height of the adapter, at the expense of making it harder to detach from the camera.
After all that, I missed the transit by a couple of seconds. I thought the clock on my phone would be accurate enough but turns out it's 5 seconds off. So memo to self for next time - shoot over a longer window, or just take a video.
