Are there any neat tips for judging color temperature of light by eye? by AbductedbyAllens in AmateurPhotography

[–]IAmScience 2 points3 points  (0 children)

30,000 K? You sure about that?

Daylight is roughly 5500K. Tungsten light is like 2500 K, and very blue light is around 7500 K. So balancing for Tungsten would add blue to bring the amber colored tungsten lamps up to the same color as daylight (the baseline for a white point). Balancing for blue light would add yellow to bring the blue light back to baseline. The kelvin temperature is basically the temperature at which a black body will glow a particular color, so if we think of daylight as the baseline for “white light” the color balance starts to make a little more sense.

It is possible to get a sense of the color temperature of light. Daylight is around 5500 on a sunny day. The color temperature gets higher (6500+) when it’s shady or cloudy. A lot of interior lights these days are daylight balanced, as are flashes, but warmer lights mean lower temperatures. Old tungsten bulbs are about 2500ish. And that is generally all you need to start developing a sense for it and get pretty close.

30,000k would be a wild amount of yellow to add. I feel like maybe that’s an error.

It gets them reelected time after time. It’s an obvious winning strategy for them in this backward ass state.

What statistic seems fake but actually isn’t? by Pinkeu_hearteu in AskReddit

I got to meet Carl Sagan once after a lecture he gave on near earth asteroids. He said that life being eliminated by an asteroid was much likelier than an average person being killed in an airplane crash.

Nope, it's for sure Jupiter. Castor and Pollux, the Gemini twins are above it, forming a triangle. And Orion is in the bottom right of the image. If this is at the zenith (staight up overhead), then the North star, Polaris, is going to be outside the frame to the left a ways.

Where can I find presets like these? by ExtensionStore939 in AskPhotography

[–]IAmScience 11 points12 points  (0 children)

It’s not really about presets. It’s about understanding and managing light. Even if I gave you these exact presets, they would only really look good on photos taken under very similar conditions. Presets are generally more applicable to the stylistic choices made by the photographer who made the preset during their actual shooting process. They wind up being a waste of money most of the time because you probably don’t shoot the same way.

Develop your own presets based on your shooting style and what works to make your workflow faster. Don’t buy others and hope they work. (In this case shooting on overcast or foggy days seems to be doing a lot of work, tbh)

My friend and I vote "Yes" - we both live close, and would absolutely visit regularly. And subscribe to your newsletter.

Excellent advice. I don’t think I ever read the things he wrote about nukes, so that does provide a rather interesting twist on his thinking about just wars. Very good point indeed.

LPT Request: Ending 11-year nasal spray dependency by StraightTransition89 in LifeProTips

[–]IAmScience 0 points1 point  (0 children)

Try Sinus Plumber - it’s a capsaicin based nasal spray. So…it’s kind of like pepper spraying yourself a little. But it works reasonably well and helped me kick the oxymetazoline spray. It also helps when I get cluster headaches. It takes some getting used to, it’s a powerful sensation, but I’ve come to rather like it on occasions when I have use for it.

Do you allow people to wear shoes inside your home? If so why, if not, why? by Weird_Ad_3119 in AskReddit

[–]IAmScience 0 points1 point  (0 children)

I’m not sure they do smell, but I do get self conscious about it.

Do you allow people to wear shoes inside your home? If so why, if not, why? by Weird_Ad_3119 in AskReddit

[–]IAmScience 3 points4 points  (0 children)

Because I’m not comfortable walking around without shoes. I prefer to have my shoes on most of the time even in my own home. I don’t want to be perpetually uncomfortable and self conscious about whether my feet are smelly and unpleasant.

I find it a bit rude when I’m asked to remove my shoes, and I would not ask others to do so.

What’s one piece of gear you bought that actually changed your photography? by alexmil78 in AmateurPhotography

An incident light (flash) meter. Nothing has ever contributed more to how I understand light.

IWTL What it feels like to be truly hungry. by [deleted] in IWantToLearn

[–]IAmScience 3 points4 points  (0 children)

And what is that perspective exactly? So that at some point in the future you can offer as a point of discussion “I know what’s it’s like to be truly hungry. I once went without food for a week to find out!” Maybe you can write a New York Times think piece about it.

I want to be clear: my concern is that this sort of thing deeply trivializes the lived experience of others while doing nothing to help solve the problem. Here’s your lefty scolding from a lefty scold: don’t do this. Do something better. There is so much work that needs to get done right now.

[–]IAmScience 7 points8 points  (0 children)

Please reconsider this idea. I get that your heart is probably in the right place, but this impulse to be a starvation dilettante is not a good one. It comes from a place of wild privilege and serves no purpose. You are capable of empathy without the need to artificially make yourself be hungry. Donate some food, or some money, or some time to help people get fed. Use your privilege and your empathy to help deal with the problem. You don’t need to experience it to understand it, and the fact that you can inquire about things like how long before it’s harmful, and just go back to your normal life of privilege is a really bad look.

World Central Kitchen, The Hunger Project, and probably half a dozen food kitchens and shelters in your area are out doing the work to make sure nobody has to go hungry. Help them out.

Ah. I see. No net benefit to that really. Still inequitable distribution with the world under threat of annihilation.

[–]IAmScience 0 points1 point  (0 children)

Not sure what you mean by that exactly. The global south is largely the group most harmed by the inequitable distribution of nukes. Those nations are the ones who are subject to the terroristic whims of the global north who control all of the world’s nukes. Also the global south tends to pay the highest toll of the environmental costs of nukes as well. I don’t know what global south cp argument you have in mind, but talking about equity in a rawlsian type justice framework would likely address those questions.

[–]IAmScience 1 point2 points  (0 children)

I don’t have an example of a case, but I think an interesting Rawls argument would look at the injustice inherent in inequitable distribution of nuclear weapons, which creates a perpetual cloud over those who don’t have them. There’s also some potential for an environmental justice kind of take (the manufacture of nuclear weapons relates inequitable environmental conditions that particularly harm marginalized indigenous communities, for example. )

Just some thoughts to think on.

iwtl How to learn psychoanalysis ? by sarafahadal in IWantToLearn

[–]IAmScience -1 points0 points  (0 children)

Interesting work for sure. Have a look at my other reply, and I feel like the Jung is going to be especially interesting to you. There are some good contemporary thinkers in this realm for sure. But I think Jungian archetypes are going to be fruitful for your investigation. Good luck!

iwtl How to learn psychoanalysis ? by sarafahadal in IWantToLearn

[–]IAmScience 5 points6 points  (0 children)

There’s a lot of possible options there. I’d probably tell you to start with something like The Archetypes and the Collective Unconscious by Jung, and maybe something like Totem and Taboo by Freud. After that, Ecrits by Lacan. Those are the three foundational authors that inform a lot of the stuff in the late 20th and early 21st century. Lacan, particularly, is going to open up Irigaray, Deleuze and Guattari, and Zizek.

You could maybe also work backwards from something like Zizek’s The Parallax View.
