BitCam 2 is live! A complete rewrite and upgrade of this classic 10 year old iPhone 1-bit camera app: Greatly expanding the Camera mode, adding a brand new Editor mode full of pixel-perfect surprises, and full native support for iPad/macOS Free download! bitcam.app

If you’re not a giga camera nerd, all you need to know about the iPhone Duo main camera is that in terms of physical sensor size it’s between the 13 Pro and 14 Pro 14 Pro has identical sensor size as the 18 Pro, btw

Many film cameras have inspired me over the years, but only 2 digital cameras have made me feel like they're something truly special (talking about hardware + output here; sadly even on those, the software is nothing inspiring...)

I know there's only like 7 of us using the Apple Music Classical app but the mismatch between icons in 27.2 is just adding insult to injury

The real sign that HomeView fits perfectly within Apple’s home devices strategy is if gen 2 comes in 2031 with just a chip upgrade, price bump, and new colors

One nice thing about maintaining several apps is that you can use the smaller/lesser used ones as sandbox for experimentation before committing to big design directions on the larger/more popular apps. Trichromy fans, there aren't many of you, but there's a cool update coming :)

The app’s screenshots have been unchanged for dozens of updates, literally the same for several years now, and all of a sudden App Review decides they’re not good anymore 🙃

If the iPhone Duo has the main camera sensor of the 17e, purely in terms of size (1/2.55”), that’ll put it on par with the 11 Pro & 12 Pro If it has the sensor of the Air (1/1.56”), that’ll put it between the 13 Pro (1/1.7”) & 14 Pro (1/1.28”)

Updated my iPhone Pro camera reference chart Another year with a 1/1.28" Sony 90X sensor, we know what to hope for for next year...

Bayer Cam lets you set the variable aperture on the 18 Pro at four distinct values, like the default camera app does; but you can also set it to be continuous

Bayer Cam now lets you pick which RAW decoder you want to use- including the ML-based v9 people have been hyping all summer It is quite a bit slower than v8, and the difference is subtle in most shots - so I get why v8 is still the default. Still, if you shoot a lot in low light, might be worth it!

Little details: the processing knobs in Bayer Cam reflect what they control, based on the value they’re set to the HDR knob glows brighter than others based on how high it is set the MONO knob renders the color spectrum to match the selected contrast filter

Up to 20% faster processing speeds in Bayer Cam 2.1 and because the interface displays a technical readout on every capture, you don't have to take my word for it: users who pay attention will see the actual numbers :)

Just released Bayer Cam 2.1! Lots of new things in this update. - Variable aperture support for iPhone 18 Pro. Like ISO & Shutter Speed, you can leave the control on auto, or lock it to a specific value - other controls adjust as needed. Start chasing those sun stars!

Another new processing setting: HDR, with 4 different intensities (& off). I'm still a bit skeptical of HDR - but experimenting with it over the last few months, I've found that it can create absolutely gorgeous black & white results. You should definitely try it!

And finally a nerdy one, but Bayer Cam is a tool for camera nerds: you can now set which RAW decoder to use Default is the classic v8; on iOS 27, you can pick the much hyped v9 (better denoising with Machine Learning at the cost of slightly slower processing) Or experiment with the older v6/v7

2.1 brings a bunch of new processing additions: a MONO processing option for black & white processed shots, 4 different color contrast filters to choose from.

To look at photos together, instead of huddling around a phone, use a lightbulb computer to make them large and put them somewhere everyone can see

Tbh as an image quality nerd, this is one of the demos I had the most reservations about - but in practice, reviewing large photos together is fun! Even if color fidelity takes a hit if you're not projecting on a perfectly white surface.

“Hey lightbulb, show me an award winning book from a female author I haven’t read” Modern computer vision models can read detailed everyday scenes almost instantly & with high accuracy - this enables a lightbulb computer to understand the world around you, and quickly answer complex requests.

While I was working on Lightbulb Computer over the summer, I learned that some people use projectors to help with cutting & sewing fabric. Very cool!

A lightbulb computer lets you pin notes, timers, and other widgets in the world around you You can stay focused on what you’re doing, no fussing with a screen (especially nice with wet or messy hands), and everyone in the room can see it too, and join in

We can build a world where people do things with digital information together, in the real world, without tiny screens or awkward smart glasses

Planning a trip on a table-sized map with someone; pinning recipes, timers, and widgets to the kitchen wall while cooking with messy hands; asking my bookshelf to highlight a book I can’t find; and more - all without a phone or smart glasses.

I’ve been asking non techie people recently what they think of foldable phones, and if they’d consider getting one - and a common response I get is “Bigger screen sounds nice but I’m too afraid it’d break”

I keep hearing iPhone camera reviewers ask why Apple did not include ISO in the Pro controls My best guess: the iPhone processing pipeline works by fusing multiple frames, with different exposure parameters, to form a final image with much better sharpness/contrast/noise reduction/etc.

Shutter speed is same; but you can't accurately replicate the exact characteristics of a slow shutter speed exposure in processing like you can w/ grain This makes shutter speed control a bit more special & Apple has confirmed that if you set shutter speed manually, the capture uses a single frame

This results in an image with significantly different characteristics, as reviewers have been observing For a true single frame workflow that lets you set ISO, shoot Bayer RAW - with Bayer Cam :)

So the notion of a single ISO value doesn't make sense in a computational pipeline like it does for film/single digital exposure If you want grain in your photo, this is why Apple added Grain/Texture control

Apple has high-level APIs that make building UI automagical But when experimenting with new hardware I like to rebuild everything from scratch to understand the fundamental building blocks An old habit from when I was a UI prototyper in Apple's Hardware org, with only basic firmware to work with 😄

On every iOS device until the Duo, the camera sensor orientation matched the screen orientation, which made the elegant design of 65x24.app possible On iPhone Duo this isn't true anymore, and it's going to be a bit of a pain to solve. Luckily, I have lots of ideas...

Camera app on iPhone Duo fills the front screen- but the camera sensor has a 4:3 (1.33) aspect ratio, whereas the Duo is 1.45 This means there's about 10% of the image's horizontal dimension missing from the preview An odd decision, but I guess they preferred that over having 170px of black edges?
