Exposure control in the mirrorless camera era: Perfect the image in camera

I took a walk in the woods yesterday and carried the Leica Q2. It actually was Craig Mod who sold me on the value of a light, autofocus full frame camera with a fixed lens that has the same field of view as my iPhone. That’s right, the iPhone and the Q2 have 28mm (equivalent) lenses. While I’ve always been and probably always will be a 50mm normal lens photographer, the 28mm provides what we now think of as normal view of a scene now that we see so much of the world through the iPhone lens.

One of my adjustments has been to go into image making with the idea that I may crop the image. With my usual 50mm view, I can usually own the frame and almost never crop. But the 28mm view and high resolution of the Q2 makes cropping a different way of seeing and perfecting the image.

Making the images reminded me of how I resolved my struggles with digital capture exposure control. If you search the net you’ll see a confusing range of views including expose to the right, expose to the left, ISO invariant exposure, and dynamic range- blowing out highlights vs noise in the shadows.

Ignore it all. Greg Williams who also uses a Q2 would tell to adjust exposure in camera to properly expose your subject. I was happy to pay for his course which goes into detail on his shooting methodology. It’s worth it to learn about how to take photos of friends and family that capture emotion and personality.

But Greg is happy to share his approach across instagram and multiple interviews across the internet. Here’s a nice one: Martini Collaborates With Greg Williams To Help You Take Better Photos – Cocktails Distilled

Your best camera will always be the one that’s with you! While I of course use professional camera equipment, I also shoot on my smartphone everyday. Get to know the functions you are working with – for example, when taking photos on a sunny day, the auto exposure might overexpose your subject. You can manually control this by using the exposure function and you will immediately see how your friends truly become the subject of the photo . The important thing is that you expose for the subject, which very often means overriding the auto exposure in either direction.

You’ll fine videos and articles showing Greg using an iPhone for celebrity shoots. Or the Q2. Or the Leica SL2 with a 75mm or 90mm. All autofocus and all mirrorless. You see, when you shoot with a rangefinder like my Leica M10 or a DSLR like my old Nikon D850, you’re looking through an optical viewfinder and see the camera’s point of view, but not what the camera sensor is seeing. When you use a mirrorless camera, you view the scene through a screen that’s either on the back of the camera or a little screen where the viewfinder used to be. And because you’re seeing what the sensor input will look like after processing by the camera’s electronics you’re not previsualizing the image (as Ansel Adams put it) you are actually seeing the image. Now most of us will save the image in RAW format which is the sensor data suitable for post processing, the data is optimal for recreating what you saw on the camera screen.

So now it becomes more or less useless to outguess the camera’s electronics and exposure system. I’ll usually shoot in aperture priority mode and let the camera choose shutter speed and ISO. Then as Greg suggests, I use the exposure compensation dial to get the subject right. If its a bright patch of light in the forest, I dial the exposure down until I get the balance I want. If I have the Q2 and I’m in a monochrom mood, I can set the image filter to monochrome and visualize the composition and exposure in black and white. The iPhone camera has a simple on screen control to change exposure.

If you look at Greg’s images, not only are they full of light, but they are shot under the most difficult lighting conditions. I think he gets away with it because he doesn’t care. He points the camera, adjusts exposure for the subject by using the in camera processed image and captures unique impressions of people.

We often like to over complicate our process, but in the world of mirrorless cameras its as simple as seeing, adjusting and capturing.

Steps toward Deciding Better

Now that I have a working method of collecting notes during the day and publishing, I’m thinking about how to store and possibly curate these notes. They get transferred to DEVONthink as markdown. Then what?

It turns out of course that my old friend Tinderbox can split notes by delimiter. So I can move my Journal entries into Tinderbox, divide by headings or horizontal rules then process and summarize! Summaries can be sent back out Drafts as Markdown to publish.

Back in 2003 or so, there were a few us besides Dave Rogers who were exploring how to blog or supplement blogging with Tinderbox. I had forgotten about Jazz and Tinderbox

It’s hard to edit a manuscript when you’ve just scratched the surface of so many subjects. I get distracted by bringing in more examples, more explanatory concepts.

In the chapter I’m editing about uncertainty, I introduce systems theory, chaos and emergence. Along the way, its interesting to think about our current machine learning algorithms are providing insights into complex systems that can’t be solved analytically. Protein folding is an example of a problem domain where our brains run out of power to analyze and analytic methods fail. But modeling works well. For example DeepMind says it will release the structure of every protein known to science

Via Sean Carrol’s podcast, I learn about a rigorous approach to defining emergence using time and prediction, called Granger Causality.
168 | Anil Seth on Emergence, Information, and Consciousness – Sean Carroll

The behavior of the flock seems to be more than the sum of the behavior of the individual birds. In some interesting way that leads us to say, “Oh, it’s a flock and it’s not just birds flying randomly all over the place.” Or, birds flying in some sort of super fighter jet formation where they’re very rigid and there’s no interesting dynamics going on.” So my challenge then was, how do we measure that? Let’s say we have a simulated bird flock. What’s a way of applying a measure so that we get a high number when it looks like a flock and a low number when it looks like the birds are just randomly doing their thing, or flying in a rigid formation? And the approach then that I took was to use a method that I’ve been using in neuroscience for a bit, called Granger Causality. And this is… Speaking of terrible names, this is another terrible [laughter] name ’cause Granger Causality has nothing to do with causality, it’s to do with prediction.

So now I have a whole new idea to play with in trying to explain why our ignorance in the face of complexity makes deciding hard even when systems have strict rules. And how shifting to an ecological mode of thinking allows deciding better as part of the system rather than maintaining some illusion of control.

How Twitter Stole Blogging

I continue to think about this rebirth of blogging idea. We want open systems where we can talk to each other while owning our content without needing to monetize ourselves or feed tech giants. In that period of 2003 or so, we had an established ecology of RSS and ping-backs to create conversations. Discovery was from referrers or via search engines. Then Twitter created its integrated microblogging platform and used retweets, mentions and hashtags to create a unified service that did what we had, only much more conveniently. As Twitter scaled due to the network effects, it swallowed the distributed architecture we had running across websites. Even now, the most prolific, dedicated bloggers have to leverage Twitter to maintain the relevancy of their sites. Most just give up on the external site and blog directly on the Twitter platform.

We need to replicate the Twitter affordances with an open model, restoring RSS discoverability ping-backs and blog specific posts in unified tools for discovery, reading, writing and conversation.

Blogging

I’ve got a daily workflow that’s clearly working. I think I’ve written every evening for a week. It feels like the work is already done and needs editing because I’ve got a set of notes in a Drafts document.

Today I added a step of pushing the files to DEVONThink Pro and and sending them to the Drafts Archive once I’ve pushed the file to WordPress and published on the site. So that’s a daily inbox, editing and publishing workflow.

So do I process these daily notes further? They are nicely searchable in DEVONthink but as daily note entries they are a mix of topics. I’m think that maybe I need to start accumulating some notes on themes for a bit of synthesis. I should focus on editing the book manuscript. Today I finished my first pass through Chapter 3 on Values and printed out Chapter 4, the introduction to uncertainty. The focus of these first chapters is exposition of the main aspects of decision theory but recasting options, values and probability as subjective, personal judgements rather than anything external or verifiable.

Art

I’ve often thought that the true test of art is whether it lasts in the mind, provoking recollection and reflection. For example, Mr Corman on Apple TV seemed interesting, but I had trouble getting through the first episode. It felt like it had pretension to art, but struck me as dreary and dislikable. Like one does with art sometimes, I gave it a chance and now that it’s done, I find myself reflecting on it from time to time. The show’s theme of living after failing to achieve the dreams of youth is a powerful one. It’s something everyone deals with in their life’s journey, but a subject not often depicted so honestly. And even the most successful people, Joseph Gordon-Levitt included I have to assume, have not done all the things they aspired to.

Most of us won’t make a living from our creative practice. We create for ourselves and share the product for validation and ego. I respect Cal Newport for this. He’s a working academic but has long put in enormous effort into writing and adding positively to the public discourse. I think the work suffers when it becomes a brand and disconnected from the life. The best journalists are working on understanding history as it happens, not simply gaining audience. I think we’d rather have a few students or even some disciples rather than an audience.

Evolution depends on variation

I find that discussions of evolution focus on selection and the adaptation of organisms to their environment. It’s important to remember that selection can only occur when there is pre-existing variation, so that successful species will have genetic variability that expresses itself as individuals that differ one from another. It’s our differences that have enabled our survival.

The complex systems that we deal with every day like forests, corporations and cats are there because they are stable. A virus that rapidly infects and kills every one of its hosts is successful for only a very short period of time. The virus that infects, kills a few of its hosts but makes the rest stronger will hang around for as long as the ecology lasts. It the stability of complex systems that keeps them going long enough that we can actually observe them.

While stability is the key to survival, predictability is not. If a bug responds the same way to each stimulus, it’s predators can anticipate the response every time. Organisms build in unpredictability.

I heard this today: “I take it for granted that everyone would like to function at a higher physical, mental, and spiritual level. Do you really need a plan to get there or just a desire to show up and do the work?”

Notes and Notes

It’s easy to push interesting ideas and articles into drafts all day long using the share sheet across my Apple products. It’s becoming habit. At the end of the day I end up with a page of collected notes. Just bullet points and links. A quote or two. The process is to sit down for a bit at the end of the day, cllean ’em up and publish the blog.

I’ve adopted some of the Zettelkasten principles in my note taking for specific projects. With back linking being all the rage in the new generation of note taking apps, I think the point is being missed. The power of the Zettelkasten is in the processing of notes and writing higher level summaries that link down to the individual items being considered. And when summarizing items, drawing the link to a similar idea directly. But this is linking with awareness, not creating a rat’s nest of linkage.

Brain

To understand how we decide, it’s necessary to understand how the brain creates feelings about options and the odds of different outcomes. It’s not a rational, algorithmic process, but one driven by imagination and emotion. That emotion is coded in deep parts of the brain known collectively as the limbic system, but areas distinct from those representing sensation, language and action of the cerebral cortex. Feeling, desire, need or more broadly positive or negative valence is evoked by those representations. Our brains get into poorly functioning states like depression, anger and anxiety that can flood all sensation and action, blinding us.

So it was nice to see the Washington Post illustrating the struggle of college students with mental health in the pandemic on their app with a brain.

When I saw mental health represented by a brain not a face or abstraction, it gave me hope the the idea of embodied cognition is catching on in popular conception, with acceptance that our thoughts and emotions are based in physical events in the brain. Mental health is brain health. Healthy mind in a healthy body.

Learn the art of the pleasant but firm rebuke. When, in casual conversation, I hear vaccine or public health misinformation being shared, as a physician I feel obligated to correct it. But its hard to relay to others that this is really important, the science and medicine matter, and that even though we have lots of uncertainty and lots to learn we need to work to separate the honest truth from the tales told to inspire fear.

Apple News

Apple announced its new MacBook Pro with higher powered Apple Silicon chips.

Things are kind of pathetic over at Intel even before the latest. My son’s gaming and streaming computer has an AMD Ryzen processor and NVIDIA graphics.

But I’m betting that the 14″ MBP with the M1 Max I ordered is as fast or faster than that huge hot box. And I finally have a laptop with a notch! Arriving in a week? Outstanding work, Apple.

I was hoping to replace my Mac Mini with a faster one, but no announcement. It will probably come later, but for now I’ll consolidate with a fully decked out laptop, something I’ve avoided in the last few years wit more mobile computing generally being done on iPad. Like this casual blogging I’m doing at the moment

Confusion reigns regarding Apple’s Apatial Audio. Apple isn’t helping. In fact, they seem to be fostering the confusion to move product. They confused everyone again in the announcement today.

Spatial Audio works with any headphones, not just the Apple iPod Pro and Max. Those apple products automatically switch it on with the default settings. When I’m using my fancy Sennheiser or Dan Clark headphones through an external DAC, I just need to manually switch it on in Settings. I actually have a shortcut on my iPhone to switch because sometimes my iPhone feeds a DAC connected to speakers. But on my iPad, it’s always turned on since I only ever use digital out for headphones, never speakers.

Om expresses my thoughts on the iPad Mini. Early on there were lots of small tablets that were best used hand held. My iPad Pro is an extremely flexible, portable device. The mini is more special purpose, great for reading and scribbling.

Rules for Casual Blogging

Rule 1: Streamline your workflow. Then refine it some more. Repeat until there is no friction and a thought is a post

Rule 2: Capture that thought like you’re bullet journaling. Don’t wait until you’ve written the well researched, fully argued discussion. This is a blog not an Atlantic article or your Bloomberg column. Those are written, edited and re-edited to drive clicks and ad revenue

Rule 3: Write for yourself. The audience may or may not show up. It’s for you, not for them. Forget search engines and SEO. There’s no magic algorithm that’s going to gain you readers. Only community and participation in the conversation.

Case in point is Dave Rogers putting off a post and breaking Rule 2.

So, a couple of ideas for long-ish posts. Probably going to take a few days to pull together. The risk is that they ultimately never come together

Dave Winer is also a cyclist. I agree with him that, for the cyclist on the public roads in America, car drivers suck. As Dave points out, sometimes they honk as they approach you. Sometimes they honk as they pass you. Sometimes they throw litter at you. Sometimes they sideswipe you. A good rule (I’m full of rules today, it seems) is to take over the lane clearly and unambiguously when it is not safe to pass and move over toward the right only when its safe and they have room to go by safely. It turns out that traveling by bike is very safe by most measures even though sharing the road with distracted drivers in multi ton vehicles can be stressful

Craig Mod tells a cycling tail.. One of the pleasures of blogging is having a way to publicly appreciate the work of hard working, talented artists. Craig is the real thing. Check out Craig’s site. Subscribe to his newsletters, buy his book, and if you like it, support his work.

In other news of Japan, my 2022 Hobonichi arrived from Jet Pens. More gratitude to Jet Pens for importing so much cool Japanese stationary and thanks to the fountain pen and notebook community for uncovering and publicizing these products. All enrich my life.

Plotter is launching its products in the US. This is a loose leaf style system from the folks at Midori who make the MD great notebooks and the Traveler’s Notebook system. I’ll pass for now, even though David Allen has said that the best GTD system is a loose leaf notebook. My best GTD system was the Palm Pilot and I mostly try to emulated using plain text editors on Mac and iOS.

One last great product is the Birkenstock Arizona EVA Sandals. I bought a pair this year after reading this Wirecutter rave. In the fall, I switch back to my Boston clogs, but I can see wearing the EVAs into the fall with socks.

Cycling

Dave Rogers and I are having a conversation about cycling.

I’ve been a cyclist all my life really, but in my mid 60’s am now in my most intense period every. I can’t be sure whether I’m faster now than ever before or more fit than ever before since age becomes such a huge factor at this point. In the last few years its become a much bigger focus. I was riding when I had my paper route for the Hudson Dispatch in Fort Lee, New Jersey. In high school I had a Sears 3 speed which I frequently rode over the George Washington Bridge into Manhattan to circle around the Cloisters. I picked up riding again in Medical School when I bought a classic Raleigh Gran Prix which I rode out to the now rather infamous Stone Mountain. During my years here in Baltimore, I’ve ridden on our local roads pretty consistently when family and work responsibilities allowed.

About 3 years ago, when my internist suggested I get a bit more regular cardiovascular exercise to supplement my weight training, I began this latest phase of seeing just how well I could perform on the bike. After starting out with some training plans from Zwift for use on a smart trainer, I ended up with a local coach, Mike Birner and a serious commitment to riding.

This morning, the schedule was for 3 hour ride. I rode with a small group from our local bike club on the flatter terrain west of where I live.

I mentioned having finished the Foundation Trilogy yesterday. For some reason, I’ve been re-reading a few of the classics. This year I read the Hobbit and the Lord of the RIngs trilogy and the original Dune trilogy. They all hold up very well. We don’t seem to read Heinlein anymore. I wonder how Larry Nivea’s Ringworld books would hold up. I was a big fan of Phillip Jose Farmer’s Riverworld books. Some streaming platform will probably try to adapt them at some point I suppose.

I don’t see making a series out of the Foundation books. There’s no villain and no conflict except history itself.

I’m hoping for a Mac Mini from Apple tomorrow that supports my two monitor setup. I really need a replacement for my current mini with a bigger internal hard drive, but the first Apple Silicon version was too limited in monitor support to use.

Last night I had some sad dreams. Old friends and mentors acting totally out of character. Lost items which disappear in greater numbers the harder you look until nothing is left. Interestingly, the few prospective studies of the emotional content of dreams have shown about equal positive and negative emotional valence, but this is biased by recall of dreams from just before awakening. The functions of dreams and sleep continue to be guessed at but seem central to preparing the brain for another round of activity in the waking state.

Dreams are passive creations of the imagination. Awake we have a drive to create things separate from ourselves. Blogs, bookcases and fancy cakes. Is this a way of creating a legacy? Something to outlast ourselves, independent from ourselves? In the end, becoming better versions of ourselves has to be our most important act and our greatest legacy.

I finally got around to watching Marvel’s Black Widow. Not bad but mostly just the usual parade of set pieces including car chase, fighting the invincible robotic bad guy. Felt transitional and not as emotionally deep as the studio’s best.

Also finished Azimov’s Foundation Trilogy this afternoon. Amazing how well it holds up as science fiction written in the 1940s. One reason is that it uses technology gimmicks sparingly, needing faster than light travel between worlds, but leaves vague communication methods and mostly deals in what people say and do. Not at all cinematic like most contemporary sci-fi but does have the modern technique of cutting back and forth between story threads, making it feel modern in that non-linear way. Now I can watch the Apple streaming series without it affecting my view of the original, although I understand the streaming series is very loosely based on the story.

It’s hard for me to place Foundation as written in its time period, although like The Hobbit and Lord of the Rings, national power and the importance of the individual are themes central to the stories. Always about people, institutions and making choices.

I added back a link to Amazon for the book just as an affordance for you dear reader if you want a quick way to get it on Amazon or read on Kindle.

Blogging more means reading less. For the most part its just a time constraint. There’s work, physical activity, household needs like shopping and cooking. This morning getting some editing time in on the book manuscript was my priority.

I’ve found the most powerful productivity hack is simply routine and having just a few priorities. Then, I just trust that what needs to get done will get done.

I did read this early this morning in a newsletter:

In Novardok (Yeshiva), they repeated a million times: you are not responsible to ‘finish”. Reb Yisroel Salanter (b. 1809 – d. 1883) said: just “do”, don’t ‘complete”

I’ve found that if you release some of that urge to control and step back a bit, you get way more done with lower stress.

Or as Dave Winer says “Keep Digging”.

Capture Everywhere, Read Everywhere, Write Everywhere

Dave and I chatted on Twitter today. You do that and you drive views to your site. But we don’t want views, we want community and conversation.

I’ve been describing my Drafts to WordPress blogging flow for these daily notes.

Dave wants an app for mobile that would be similar but a flat outline that he can edit and deploy as needed.

I think we agree that Markdown is a fine way to structure plain text documents. In most text editors like BBEdit or Atom, Markdown is recognized as a code syntax and it’s easy to fold and move blocks marked off by Markdown headings. Of course FoldingText was designed to do this in a slightly different way. We eventually got TaskPaper which has been updated more recently but with its own todo oriented markup.

The only mobile app I have that does folding based on Markdown is Editorial but its not kept up with current sync methods like Cloudkit or iCloud folders.

That’s creating structure within a file. I see my nested folders as an outline with the bottom layer being individual files. And in general, I’m fine with one file at a time for reference or writing.

But with this resurgent environment of note taking and blogging, I’m hoping for some new solutions besides the big note taking back linking systems of Obsidian and Notion and Craft which seem so closed to me.

Outlines mostly live on in the form of mindmaps. From David Allen:

I f you’re concerned about your ‘work-life balance’ I’d encourage you to grab a pen and paper and draw a mind map or a list of your Areas of Focus, both personal and professional. Then you may see which parts of your world you have been too focussed on and which deserve more attention. Whenever I feel a sense of imbalance I ‘pop up’ to visit this horizon

Another category that died was the Reader like Pocket and Instapaper. I use Safari’s Reading List now or quick capture to drafts, but that’s bookmarking. What I’d like is an app to open on my iPad that would be like the Kindle app but give me webpages, PDFs, email newsletters and RSS feed articles all integrated. While the ways these reads get to me are different, in the end its all reading. You know we used to have books and we used to have magazines and we used to have newspapers. Now it a torrent from every direction leaking through every crack it can find in the information environment.

Time to read a book now.
