Media Preservation Monday

Yeah, yeah, as of this original post it's actually only Wednesday but hey, take this as a sign to take some initiative, and keep to it each Monday at minimum if you're actively writing!

What's Media Preservation Monday, you may ask?

MPM is your reminder to back up your writing at least three ways at least once a week or whenever you make major changes to your document(s).

Here's some incredibly easy ways to back up your writing:

One your Master Document(s), put a date on the file name, and every day you make changes, "Save As" the Document and change the date. Do this every time or day you make major changes.

Example: You start writing your Novella November Story on November 1st.

You name your master document "Novnov Project 11-01-2024"

The next day, you write some more, and at the end of your writing session, you go to save your document, and instead of simply hitting "Save" you choose "Save As" and save the new copy of the Document as "Novnov Project 11-02-2024".

You now have two copies of your project, and if you keep this up throughout the whole month, you will have a live snapshot of your writing progress.

Each day or after each major writing session, open up the folder containing your document, and back it up. The Easiest and simplest way to do this is to simply email it to yourself, but you can also create multiple backups by:

Save a copy of your dated Master Document(s) to different locations on your Hard-drive, to an external hard-drive, to a thumbdrive, etc.

If you're writing offline on a writing program like Libreoffice, upload a copy of your Master Document(s) to your preffered Cloud-based Writing Program of your choice.

Vice Versa: if you write on a Cloud-based writing program, download it to various offline-based locations.

Download the base document as well as download it as various ebook formats and send them to your ebook library on your phone or kindle or nook or reading app.

Make a personal discord server and upload the document/epub form of your Master Document(s) there [this is also a good way of making a kind of personal journal / diary etc]

Whatever you do, do not be complacent and assume nothing can happen to your writing. Back it up. Preserve it.

Don't have all of your hard work go down the drain because of one tiny unforeseen accident.

When it comes time to clean up your hardrive, always assume you don't have it backed up. Before deleting anything always take the time to copy it over to another physical drive or a cloud drive.

Explaining a Supernova’s ‘String of Pearls’ - Technology Org

Explaining a Supernova’s ‘String of Pearls’ - Technology Org

Physicists often use the Rayleigh-Taylor instability to explain why fluid structures form in plasmas, but research from the University of Michigan suggests that that may not be the full story about the ring of hydrogen clumps around supernova 1987A.

The simulation shows the shape of the gas cloud on the left and the vortices, or regions of rapidly rotating flow, on the right. Each ring represents a later time in the evolution of the cloud. It shows how a gas cloud that starts as an even ring with no rotation becomes a lumpy ring as the vortices develop. Eventually, the gas breaks up into distinct clumps. Image Credit: Michael Wadas, Scientific Computing and Flow Laboratory

In a study published in Physical Review Letters, the team argues that the Crow instability better explains the “string of pearls” encircling the remnant of the star, shedding light on a longstanding astrophysical mystery.

“The fascinating part about this is that the same mechanism that breaks up airplane wakes could be in play here,” said Michael Wadas, the study’s corresponding author and a graduate student in mechanical engineering at the time of the work.

In jet contrails, the Crow instability creates breaks in the smooth line of clouds because of the spiraling airflow coming off the end of each wing, known as wingtip vortices. These vortices flow into one another, creating gaps—something we can see because of the water vapor in the exhaust. And the Crow instability can do something that Rayleigh-Taylor could not: predict the number of clumps seen around the remnant.

“The Rayleigh-Taylor instability could tell you that there might be clumps, but it would be very difficult to determine their number,” said Wadas, who is now a postdoctoral scholar at the California Institute of Technology.

Supernova 1987A is among the most famous stellar explosions because it’s relatively close to Earth at 163,000 light years away, and its light reached Earth at a time when sophisticated observatories existed to witness its evolution. It is the first supernova visible to the naked eye since Kepler’s supernova in 1604, making it an incredibly rare astrophysical event that has played an outsized role in shaping our understanding of stellar evolution.

A near-infrared image of the remnant left behind by supernova 1987A, taken by the James Webb Space Telescope. The hydrogen clumps known as the “string of pearls” appear as a ring of white dots around the teal center of the stellar remnant, still shining brightly due to the energy imparted by the supernova shockwave. The number of clumps is consistent with the Crow instability having caused them to form. Image credit: NASA, ESA, CSA, M. Matsuura (Cardiff University), R. Arendt (NASA’s Goddard Spaceflight Center & University of Maryland, Baltimore County), C. Fransson (Stockholm University), J. Larsson (KTH Royal Institute of Technology), A. Pagan (STScI)

While much is still unknown about the star that exploded, it is believed that the ring of gas surrounding the star ahead of the explosion came from the merger of two stars. Those stars shed hydrogen into the space around them as they became a blue giant tens of thousands of years before the supernova. That ring-shaped cloud of gas was then buffeted by the stream of high-speed charged particles coming off the blue giant, known as a stellar wind. The clumps are believed to have formed before the star exploded.

The researchers simulated the way the wind pushed the cloud outward while also dragging on the surface, with the top and bottom of the cloud being pushed out faster than the middle. This caused the cloud to curl in on itself, which triggered the Crow instability and caused it to break apart into fairly even clumps that became the string of pearls. The prediction of 32 is very close to the observed 30 to 40 clumps around the supernova 1987A remnant.

“That’s a big piece of why we think this is the Crow instability,” said Eric Johnsen, U-M professor of mechanical engineering and senior author of the study.

The team saw hints that the Crow instability might predict the formation of more beaded rings around the star, further out from the ring that appears brightest in telescope images. They were pleased to see that more clumps seem to appear in the shot from the James Webb Space Telescope’s near-infrared camera, released in August last year, Wadas explained.

The team also suggested that the Crow instability might be at play when the dust around a star settles into planets, although further research is needed to explore this possibility.

Smartphone cameras are NOT getting worse. (See below for phone photography tips)

I've now seen 3 pro photographers reviewing the iPhone 16 and complaining the cameras are "worse" and blaming Apple for not including revolutionary new camera technology.

And I suppose this is partly Apple's fault. Their marketing and hype machine always goes overboard. But also, that's just how marketing works. Samsung has a "200 megapixel" sensor and Sony has a "Zeiss" lens. And I think it is unrealistic to expect smartphone companies to say "This product has entered the iterative phase and each new model will only be marginally improved over the last one."

Smartphones (from any brand) have become an appliance. You don't buy a new model of microwave every year. And you don't expect every new model of microwave to have new revolutionary technology. And that is pretty much the expectation you should have with most computer hardware from here on out.

And in some ways, that is a good thing. That means the design of the phone has pretty much been perfected and it will last you a long time if you take care of it. You will not be left behind and your phone will be able to handle any new software for most of its lifespan.

So, is Apple getting lazy or is there a reason their hardware is stagnating?

It seems that neither money nor marketing can change the laws of physics.

They cannot make transistors much smaller. Phones and computers are about as fast as current hardware designs can make them (unless there is a shocking scientific breakthrough). From here on out, heavy compute tasks that are beyond your phone or computer will be done in the cloud on giant computer clusters. Thankfully computers and phones seem to be plenty fast for the majority of tasks we ask of them.

I remember Katrina telling me her new computer didn't seem any faster. And I explained the computing tasks she does regularly were not really affected by the increased power and speed of her new computer. If something took 0.1 seconds before and now it takes 0.05 seconds, that is twice as fast. An increase in speed that looks fantastic in advertisements. But it is hard for our brains to perceive. She just didn't do anything on her computer that took it long enough for her to notice. But having a faster and more powerful computer/phone will increase its lifespan and resale value, so it is still prudent to get the best things you can afford at time of purchase.

And I'm afraid smartphone cameras are hitting their own hardware limitations. They can't make the sensors much larger to get better depth of field and low light performance. And cramming in more megapixels doesn't actually add much more detail, if any.

It's physics.

Again.

You cannot get any more performance out of a small plastic lens. Why do you think pro photographers haul around 10 pound lenses still?

There is a formula for detail that never seems to be explained in any camera marketing.

Here is the simplified version...

Detail = Sensor x Lens

Let's say 1 is perfection. You have a sensor that performs at 0.5 and a lens that performs at 0.2.

The total detail will be 0.1.

But in the new model you increase the performance of the sensor to 0.8. WOW! That's so close to 1!

The total detail will be... 0.16.

Now let's imagine we've discovered a magic, physics-defying tiny plastic lens that performs at 0.8 as well.

The total detail jumps to 0.64!

But we all get sucked into a wormhole because we violated the laws of the universe.

Even if you were to design a near perfect (perfect is impossible) sensor that scores 0.99.

Without that magic plastic lens... 0.198

This is why I put Samsung's "200 megapixel" sensors in quotes. Because when paired with the same tiny plastic lens, there isn't much improvement. And that's why a 12 megapixel DSLR from 10 years ago with a giant honking lens can still capture more detail.

Most of the quality from smartphone cameras comes from the computational software processing. Phones actually take many photos at once and combine them to get you a decent image.

While that is still improving a little bit each generation, those improvements are stagnating as well. Until image processing can do a better job of inventing more detail realistically, smartphones are going to have to obey the laws of physics.

So... why are photographers saying the iPhone cameras are worse?

First, the ultra wide angle lens looks softer in low light.

And if you zoom between 1x and 5x, the images look less detailed.

But neither of those things make the cameras *worse*. In fact, the cameras are better for the most part. It's just that Apple decided to compromise on one aspect to improve another. Probably due to market research telling them most people prioritize certain things over others when taking photos.

They increased the resolution of the ultra wide angle sensor to match the detail of the main sensor, but that seems to have lowered the low light performance of the ultra wide. So in good light, you will see an improvement in sharpness. But they could not increase the sensor size to compensate and smaller pixels can have trouble with dim conditions. They probably discovered that people mostly use that lens in good light and they would appreciate the bump in detail more.

But pro photographers often photograph in more challenging lighting conditions because you can capture a more artistic shot. I don't think I could have gotten this shot on a smartphone.

But photo normies are just taking pics of their kids doing weird kid shit.

They aren't really trying to push the limits of their ultra wide angle lenses.

And they increased the zoom of the telephoto lens to 5x from 3x because most people never used the 3x. So images at 5x look great now, but unfortunately if you use anything between 1x and 5x, your image will be *digitally* zoomed. Which is never as good as optical zoom. They basically crop the photo, zoom in, and add sharpening.

So they prioritized people having longer reach and more zoom at the expense of that middle zoom range. Every camera system makes tradeoffs and compromises.

And I hate that I always feel like I am defending Apple, because they do have misleading and dishonest marketing regarding a lot of aspects of their tech. But hating on Apple gets more clicks so content creators also make misleading and dishonest claims.

And so we are just surrounded in a circle of hyperbole from all sides.

Now, if you know these limitations, you can change your approach to photographing stuff to keep them from being an issue. You can reap the benefits without dealing with the new compromises.

Here are some tips to help owners of the new iPhone, but also everyone else too.

Smartphone Photography Tips

Whenever possible, try to use the main 1x camera at only 1x zoom. This has the largest sensor with the most detail and works best in the lowest light. Only use the ultra wide or telephoto if you cannot get the photo otherwise. If you aren't sure you have enough light for ultra wide, take the photo, and then as a safety, take two photos with the main camera side by side and stitch them later with a pano app.

"Zoom with your feet" and don't use "in-between" zooms. Let's say your lenses do 0.5x, 1x, and 5x zoom. Even though you have the option to use other zooms, like 2x or 3x, that is going to compromise your picture quality. It is essentially going to crop your photo and enlarge it, which causes a loss of detail. If fact, if you use 4.5x instead of 5x, your picture will probably look like trash. You are always going to get better results if you can move closer or step back so that you are using the native focal length of your chosen lens. For example, let's say you are taking a photo and you judge the best framing to be at 4x. But you still have 10 feet of space behind you. If you back up and then zoom in to 5x, the phone will switch to that lens and you will get a much clearer picture.

Rule of thumb...

1 to 3x... try to move closer.

4 to 5x... try to move back.

If you hit a wall and end up at 4.5x, you might see if you have a panorama mode and try that instead. Switch to your 5x and do the pano. Or you can take two photos and then stitch them together with software later on. (Stitching panos with an app later will give better quality than pano mode, especially in low light.)

Low light needs stability. Get some sort of stabilizing device for low light photos. Either a phone case that lets you stand up the phone on its own or a mini tripod.

This thing folds to the size of a credit card.

Your phone will detect when it is stable and not being handheld. It will then automatically extend its shutter speed allowing it to drink in more light and give you a better picture.

Tripods are photography magic and will improve your low light photos quite a bit. Motion blur of moving subjects can still be an issue, but photos of a cityscape or landscape will look great.

For selfies, shoot a little bit wide and then crop in. This goes a little contrary to my earlier advice saying cropping lowers detail, but this is specifically for shooting a face. The 0.5x and 1x lenses on smartphone cameras are fairly wide angle. This can cause unflattering proportions with human faces. Wide angle lenses exaggerate distance. Near things look very near and far things look very far. To a wide angle lens, the tip of your nose looks like it is super close but your ears seem like they are a mile away. And that's why you may look a bit "alien" in your selfies.

People's natural instinct is to "fill the frame" with a face. The outer edges of a wide angle lens are more distorted than the very center. So try to keep faces away from the edges of the frame.

And one other trick you can do for selfies and pictures of faces is step back a few feet. Sometimes this is hard, especially with selfies, as your arm is only so long... but if you can take your face photos from just a little bit farther back, you will almost entirely eliminate unflattering distortion. In some cases, just stretching out your arm as far as it will go is enough.

Then you just crop the image with the framing you originally wanted, and your facial proportions will look great.

An example...

Here the distortion is bad because I am not in the center and the lens is too close to my face. The lens thinks my nose is really close and my ears are in Canada.

But when the lens is farther back the edge distortion is less prevalent and my nose and ears (relative to the lens) seem roughly the same distance away. So my proportions look great, but I don't quite have the framing I want.

But with a little cropping...

For social media there is still plenty of resolution to crop in. Cropping isn't bad, it's just always better to use it as a last resort or in a special circumstance like this. I get roughly the same framing as in my wide angle shot, but I don't look like I'm behind a door's peephole trying to sell you the Good News.

I wish they made a "mini" selfie stick that only extended a foot or so. With the main camera that is usually all people need to undo any wide angle issues. I have one of those mini tripods and that works well, but there is no activation button so I have to do a timer. Mirrors work great to help you get some selfie distance.

In any case, all cameras have limitations and compromises. Clickbait titles saying something is WORSE THAN THE OLD ONE are frustrating and wrong.

And people upgrading phones every year are silly. All current name brand smartphones have promised at least 5 years of software updates. I think Google and Samsung are offering 7 years on some models. And Apple has always just let you use your phone until it literally will not work with new software. Which has worked out to 8 years in some cases (with a battery swap).

Phones are now appliances. For now, hardware will improve 10 to 15% from generation to generation until physics breaks. So if you want a 50% improvement, wait 5 years and you'll think your new phone is awesome. If you upgrade every year, it is going to be difficult to see the change.

I hope to be starting a little course on smartphone photography in the near future. All modern phones are capable of taking amazing pictures. And as long as you understand their limitations you can mitigate or avoid them. And that is what I plan to teach.
