Depth of Field: Real and Simulated

Four versions of the same photo.

  • One taken with my phone, which has a deep depth of field.
  • One automatically “enhanced” by Google from that phone photo.
  • One taken with my phone in portrait mode, which simulates a shallow depth of field.
  • One taken with my ancient film SLR camera, with a low F-stop to have an actual shallow depth of field.

First Try With The Old Film Camera

We got the negatives and scans back from the two rolls of film we shot with the old manual film camera. Despite the damage to the case, it seems to still be light-proof, as the second roll of film came out about as well as the first.

It was an interesting experiment. We mostly took night/indoor photos with the tripod and handheld photos outdoors in daylight. He’s not used to focusing, so a lot of his photos are blurry. The light meter app on my phone seems a little off in sunlight, so our outdoor photos are all either over– or under-exposed. (The zinc-air batter has since shown up, so with luck we’ll be able to get more accurate light readings with the next roll.) But it gave some of the photos a retro feel.

Here are a few of the better shots, plus one of the light-polluted, smoke-filled skies of Los Angeles with enough stars to recognize Cassiopeia.

Sort of Blogging on the Fediverse

Over at Key Smash!, I’ve been helping beta-test the Pterotype plugin to hook up a self-hosted WordPress to the Fediverse. It gives WordPress an ActivityPub presence, so new posts and comments can be seen in Mastodon, Pleroma, and other ActivityPub-powered networks, and replies from those networks can come back as comments.

But Key Smash! is a simple test case. It’s at the top of the site, there’s no caching, it’s only got a handful of posts, and it hasn’t been bombarded by spammers for years.

So I’ve installed it on here. Older posts won’t federate, but new ones (starting here) should, and replies should show up as comments. With luck they’ll land in the moderation queue instead of the spam queue.

You may be able to follow the site by searching for this post’s URL in Mastodon/etc. Maybe. I need to report a bug in the handling of sites that aren’t at the top level: To find the site I need to search for @blog@www.hyperborea.org/journal – the first time. Then that search stops working, but I can find it at @blog@www.hyperborea.orgjournal instead. But that only works after I’ve searched for the first one.

Well, that’s part of why I set it up here: to help beta test.

High-Rise Night: Trying out “Night Sight” on the Pixel 2 Camera

Google has a new camera mode on its Pixel phones called Night Sight, for handling low-light conditions. The short version is that instead of taking a long exposure, it takes a series of short exposures and stacks them to avoid motion blur from hand movements (plus a lot of additional processing). The long version is fascinating.

My Pixel 2 already takes better low-light photos than I would have expected, but I couldnt wait to try out the new feature when I learned about it. When the updated Camera app finally hit the Play Store, I had to give it a try.

Two high-rise office buildings at night.

This is adjusted slightly to keep the colors from being too light. And it actually isn’t the best example, as it turns out the nighttime city scene already has enough light for the existing HDR+ mode. I’m going to have to try it on some darker scenes somewhere, but it’s still pretty cool. After the cut I’m posting a version with the phone’s regular mode, and the unaltered Night Sight photo. You can see they’re pretty close, but the Night Sight version picks up a bit more of the color, and it’s a little brighter.
