Import unsupported camera RAW files into Apple Photos

Many years ago, I decided to migrate my photo library from Apple's now-defunct Aperture to Photos, so I could take advantage of Apple's iCloud Photo Library (don't worry, I still have three full complete local backups, plus a separate cloud backup besides Apple's iCloud originals).

One pain point is RAW support. As camera manufacturers add new models, their proprietary RAW codecs are updated, and software vendors like Apple, Adobe, and Microsoft have to update photo editing tools to work with the new camera models.

I don't envy them this task, but as Photos was Apple's official successor to Aperture (a pale shadow to be sure, but it has its merits as a semi-decent library organizer), they've generally done well supporting new camera models. The compatibility list for macOS Sonoma, iPadOS 17, and iOS 17 is a testament to that effort.

Photographing the 2024 Total Solar Eclipse

On April 8, there will be a Total Solar Eclipse covering an large swath of the US, offering hundreds of millions of people the opportunity to witness one of the most spectacular displays of our sun.

I wrote two blog posts about the recent 2017 eclipse, as well—check those out:

For this year, I was considering going all-in on a custom Raspberry-Pi-based solar tracking system, recording video and images... but Will Whang already built a custom solar imaging setup that would put anything I build to shame.

Testing Raspberry Pi's new Global Shutter Camera

Today Raspberry Pi launched their new Global Shutter Camera.

Outwardly it is almost identical to the 12 Megapixel High Quality Camera, and like that camera it accepts C and CS mount lenses, or most anything else with the appropriate adapter.

But flipping it over reveals a black plastic cover over the back of the board that is not present on the HQ or M12 HQ Camera:

Raspberry Pi's Camera Module 3 adds autofocus and new Sony sensor

Raspberry Pi just announced their new Camera Module 3, which comes in four variations (standard and wide angle, normal and NoIR for infrared use), and costs $25 for the standard versions, and $35 for wide angle.

Raspberry Pi Camera Module 3 varieties - standard, wide, and NoIR

That's a step up from the older Camera Module 2, which cost $25 and only came in a 'standard' focal length.

I posted a video reviewing the Camera Module 3 on YouTube, and you can watch it here:

Autofocus on a Pi - ArduCam's new 16MP camera

ArduCam with other Raspberry Pi Cameras - v2 HQ and Autofocus 16MP

ArduCam recently completed a successful crowdfunding campaign for a 16 megapixel Raspberry Pi camera with built-in autofocus.

The camera is on a board with the same footprint as the Pi Camera V2, but it has a Sony IMX519 image sensor with twice the resolution (16 Mpix vs 8 Mpix) and a larger image sensor (1/2.53" vs 1/4"), a slightly nicer lens, and the headline feature: a built-in autofocus motor.

Autofocus performance

Getting right into the meat of it: autofocus works, with some caveats.

First, the good. Autofocus is quick to acquire focus in many situations, especially in well-lit environments with one main subject. Using ArduCam's fork of libcamera-still or libcamera-vid, you only need to pass in --autofocus and the camera will snap into focus immediately.

Modeling my Grandpa with 3D Photogrammetry

Today I released a video about how—and why—I 3D Printed my Grandpa and put him on my bottle of ketchup. Watch it here.

I sculpted a bust of my Grandpa in high school, gave it to my grandparents, got it back after he died and my Grandma moved out of her house (I wrote a tribute to my 'Grandpa Charlie'), and I kept on moving it around my office because I didn't have room for it:

I decided it had to go, but asked my extended family if anyone wanted the statue (thinking it would be sad to destroy it). One enterprising cousin suggested he could 'copy' the statue in smaller form using photogrammetry:

Beautiful 3D Print time-lapses with my Nikon D700 and Octolapse

After seeing GreatScott's video on creating great 3D Printing timelapses, I knew I had to make better 3D Print timelapses using one of my DSLRs.

I had already tried using my pi-timelapse script with a Pi Zero W and the Camera Module v1 and v2, but the quality is just so-so, plus it's not synchronized with the 3D printer, therefore at least on the Ender 3 V2, the printed object goes all over the place:

What I wanted was a stable and sharp timelapse of the entire process with high enough resolution to use in HD videos I produce for my YouTube channel.

So how did I get it working with my old but trusty Nikon D700? Read on...

I'm switching from Nikon to Sony mirrorless

First let me be clear: I'm not, nor have I ever been, sponsored by Sony, Nikon or any other camera manufacturer, and all my photography gear has been purchased with my own money (usually used since I'm not made of money).

With that out of the way, after waffling on the decision for over a year, I'm selling all my Nikon FX DSLR camera gear, and switching to Sony's APS-C mirrorless camera system.

But why?

For me, there are two major reasons:
