i have this intrinsic revulsion to cutesy aesthetic small beanisms but am also deeply drawn to things that require a lot of care, detail, and nurturing which rubs up directly against those types of people often. Seeing people invested in my hobbies but they're doing it to be like #cottagecore is like such a perversion of the thing. Puppeting its lifeless corpse around for monetization purposes. Spending hours carting around your tripod to get the perfect shots to present yourself as if you are living in the moment enjoying the beauties of the world. Its honestly tragic.

1 AM is the perfect time to try to revive this laptop that doesn’t function due to windows bloat (presumably)

Last time I tried to login it froze for an hour and when I finally got in and tried to open anything it would freeze up completely.

Let’s see if it works

People seem to lack a sense of “obsolescence.” Something old might not automatically be garbage even if something new and better has come along. The older thing that is no longer in use might have been genuinely bad, but it’s very possible that it worked and maybe even worked quite well in its time—it may still work quite well now—but the new thing is still better or more effective. This is a question of societal and personal values and it has practical consequences.

I am trying to research vintage (and replica) rifle scopes right now, and it is extremely unhelpful to read people say that such and such thing is “garbage,” because I don’t know if that means garbage for its time, subjectively bad to the person speaking, or simply inferior to a modern high quality optic.

To give an analogous example, I have a pair of WWII binoculars. They’re clearly well-made, durable, good materials, and when you look through them, you can indeed see a thing that is far away as though it were closer. But my younger brother has a good pair of modern binoculars and when you look through them not only is the image better resolution than real life, it is brighter and I’m pretty sure you see colors invisible to the naked eye. It’s insane how good they are.

The old binoculars are still perfectly functional. The new ones just do the same thing much better.

Have another crappy and rough sketch of my oc

[transingthoseformers]

Oh yeah! Btw, this is my working sketch with the spinocon Harlequin, their initial concept was based on harlequin rabbits and animal chimeras. Now, like all the other spinocons, the pronouns are technically all pronouns but with heavy preference towards they/it. In my notes, they are described as "The therapist from Hell" not because of them being mean to patients, but from their demeanor on the battlefield or during interrogations, being a Decepticon tried and true.

Yes, I'm working on properly transferring the spinocon notes as I have a good 3,800 words in my working document— most of it dedicated physical description.

This is a great breakdown of phone cameras and worth a read if you do most of your photography with a phone.

Phone cameras are comparable to or better than many point-and-shoot digital cameras (especially older generation cameras, and this has been the case for several years now). But there is no such thing as a "pro" phone camera, just like there's no such thing as a "pro" point-and-shoot.

You can get really great photos and they can absolutely serve your needs. It's a fantastic solution if you're not in a position to carry extra gear with you.

But they are not "pro".

They can also be a perfectly acceptable tool for photography as an art form. You use the tools and explore and maximise their capabilities as you feel driven to. You certainly limit yourself in major ways with a camera phone, but that's part of the art. ALL photography is bound by the limits of your tool, and the entire point is to work within those and push your craft to see what you can do. So you can use the camera phone AS a pro (i.e. someone who understands the tool and principles of photography), but you have to understand the tool for that.

If you want a pro camera though, get a real camera.

Also, you need to identify the type of photography you like or want to do in order to choose the right camera.

I do a LOT of handheld, low-light photography w/o flash (museums, early or late hiking, etc.) so the sacrifice of low light quality in these cameras is the wrong decision, to me. But I also have a real camera which specifically caters to what I do. You just need to choose the tool or work within the bounds of what you have.

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.

Integrated NDE Solution in Pune: Pioneering Positive Material Identification for Quality Control and Safety Compliance

In the modern industrial landscape, ensuring the integrity and composition of materials is crucial for maintaining quality control and safety compliance. Positive Material Identification (PMI) is an essential non-destructive method used to verify the chemical composition of materials. Integrated NDE Solution in Pune offers comprehensive PMI services, utilizing advanced technologies such as X-Ray Fluorescence (XRF) analyzers and Optical Emission Spectroscopy (OES). This article delves into the intricacies of PMI, its benefits, and the cutting-edge services provided by Integrated NDE Solution.

Understanding Positive Material Identification

Positive Material Identification (PMI) is a non-destructive testing method used to verify the alloy composition of materials. PMI ensures that the materials used in manufacturing processes meet the specified chemical composition, thereby maintaining product quality and safety standards. This verification process is crucial for industries where material composition directly impacts performance, reliability, and safety, such as aerospace, oil and gas, power generation, and pharmaceuticals.

Importance of Positive Material Identification

Quality Control: Ensures that materials conform to the required specifications, maintaining the integrity and quality of the final product.

Safety Compliance: Verifies that materials meet industry safety standards, reducing the risk of failures and accidents.

Material Verification: Confirms the correct alloy composition of materials, preventing mix-ups and ensuring proper material usage.

Regulatory Compliance: Helps industries adhere to stringent regulatory requirements and standards.

Cost Savings: Prevents costly material failures and recalls by ensuring the correct material is used from the start.

How Positive Material Identification Works

Positive Material Identification is typically conducted using two main technologies: X-Ray Fluorescence (XRF) and Optical Emission Spectroscopy (OES).

X-Ray Fluorescence (XRF) Analyzers

XRF analyzers use X-rays to excite the atoms in a sample, causing them to emit secondary (fluorescent) X-rays. These fluorescent X-rays are characteristic of the elements present in the sample, allowing for a semi-quantitative chemical analysis. The key steps in the XRF process are:

Preparation: The surface of the material is cleaned to ensure accurate readings.

Excitation: The XRF device directs X-rays at the material, exciting the atoms within the sample.

Detection: The device detects the emitted fluorescent X-rays and measures their energy levels.

Analysis: The energy levels correspond to specific elements, allowing for the identification of the material's composition.

Optical Emission Spectroscopy (OES)

OES involves exciting the atoms in a sample using a high-energy spark or arc, causing them to emit light. The emitted light is then analyzed to determine the material's composition. The key steps in the OES process are:

Preparation: The surface of the material is cleaned and sometimes ground to create a flat, uniform surface.

Excitation: The OES device generates a spark or arc that excites the atoms in the material.

Detection: The emitted light is collected and passed through a spectrometer.

Analysis: The spectrometer measures the wavelengths of the emitted light, which correspond to specific elements, allowing for precise material identification.

Benefits of Positive Material Identification

Non-Destructive: PMI does not damage or alter the material being tested.

Accurate: Provides precise and reliable identification of alloy composition.

Quick and Efficient: Delivers immediate results, enabling rapid decision-making.

Versatile: Applicable to a wide range of materials, including metals and alloys.

Portable: PMI equipment is often portable, allowing for on-site testing.

Durani's work is collected on medium (including a 1st movie review)

the archived wapo article https://web.archive.org/web/20211028185525/https://www.washingtonpost.com/outlook/2021/10/28/dune-muslim-influences-erased/

Dune discourse is uniquely annoying because there's a bunch of extremely obvious, in-your-face orientalism perpetuated by the main characters that's being discussed at nauseum and is very easy to dismiss and completely overshadows any actual issues with the movie, like the refusal to use recognisable arabic phrases or the hiring practices. I'll be charitable here and assume that people have a rightfully negative reaction to how those images of white people, particularly Jessica, are used as marketing material, instead of just not getting the point, and with how often concerns like this are overlooked, I can understand why they aren't receptive to "no this thing that media does uncritically all the time is meant to be bad THIS time actually trust me bro just read this 1000 page book".

Seemingly the entire film crew having cold feet about including references to real world anti-colonial movements or just normal Arabic would always be concerning, but especially given the current situation in Palestine and it's all overshadowed by the colonisers in the book acting like colonisers because every other issue is more complicated. Dune, as a text, still believes in noble savages and "hard times create hard men" nonsense. I'm really not coming at this from a "don't criticise the thing I like" angle, but debates about Jessica's outfit have made me learn nothing besides occasionally seeing really cool pictures of real arabic clothing, while reading Haris A. Durrani's dissections of the books and the current adaptation has actually tought me a lot of stuff about both the book and the real world.

If you haven't seen his Dune essays, you can find a collection towards the bottom of this page: https://history.princeton.edu/people/haris-durrani

https://acoup.blog/2020/01/17/collections-the-fremen-mirage-part-i-war-at-the-dawn-of-civilization < This blog post isn't specifically about Dune, but it uses the Fremen as an example to discuss the historic origins of the noble savage trope (Acoup is generally a cool history blog, mostly focused on greek and roman history)

I love Dune but it's so problematic, just not for the obvious reason and dissected Frank Herbert's actual politics and the strange intersection of conservatism and anti-colonialism is fascinating. You should criticise Dune, I would just like the criticism to be better, especially because focusing on the thing that is framed as bad in the story gives every chud an easy way to dismiss criticism of the text as bad media literacy

If anyone ever wonders, because the cost difference, if migraine tint glasses are different from just a rose/pink tinted: I think so. I just got a replacement migraine glasses and a pink one to try out. The pink makes things look noticeably......pink. I think the migraine glasses keep colors clearer. I think you'd have to get a fairly cool tone pink to have it be effective. I think lavender is too cool toned.

I really don't know if I believe the specific shade, but I do think the tint on the migraine ones is better than normal tinted glasses.
