They don't look that stagnant to me? Each one seems to have multiple inlet/outlet pipes, and the next pond over has an aerating fountain. If they were truly stagnant the car wouldn't be visible.

I see them in my area on flightradar24, running very consistent grids like this one: https://www.flightradar24.com/blog/wp-content/uploads/2015/0...

Authors don't always have a final say on what the headline will be. Sometimes they don't have any say at all.

I wonder if there were any environmental or health issues associated with the manufacture and finishing/grinding of these lenses. The EU forced camera manufacturers to stop using leaded glass a while back because of worker's health.

Paulownia tomentosa. Known in my area as the princess tree, but also goes by royal paulownia, foxglove tree, kiri, and empress tree.

> indie music stores like Bandcamp are digital only

Many bands on Bandcamp offer bundles of vinyl, CDs, t-shirts, etc. with the digital download. One example off the top of my head:

According to the Times:

>Mr. Alles was told to develop an exit plan before the arrest of a Chinese woman carrying a malware-laced device at Mar-a-Lago, exposing holes in the security of the private club.

> how would I go if I wanted to harvest large numbers of "real" photos of "real" persons?

I guess you could just steal them from Flickr?

It is a Schlieren technique, but in this case a series of images taken over a textured background are then processed with software in a way that amplifies the differences in air density. This page goes into a little more detail:

Do you have a brand/model recommendation?

Compasses manufactured for the northern hemisphere have extra weight added to the "south" end of the needle because the "north" end is partially being pulled toward the ground as well as the north magnetic pole. So your compass probably just wouldn't work at all.

Very doubtful. The NYNJ system is not very high capacity, doesn't have an easy connection to passenger lines in New Jersey, the connecting lines aren't electrified, and would leave passengers in the far south end of Brooklyn.

I don't call the gas company, I call the fire department. They tend to take paper trails a lot more seriously.

It's silly, but I do carry around a notepad so I can make a list of things to look up later.

Just in case you didn't read the article, it makes no mention of the researchers' maintenance ability.

"According to the researchers, while the study was purely curiosity-driven, the results could be used to develop more efficient ways to measure rainfall or to develop a convincing synthesised sound for water droplets in gaming or movies, which has not yet been achieved."

It's actually a little less involved than B&W. You don't have to look up developer/film times and there are no agitation timing techniques to worry about, because the process is exactly the same for every roll. The only annoying part is getting the chemicals up to 100 degrees rather than getting room temperature water straight from the tap.

Cosina was the company licensed to make the Nikon FM10 and produced rangefinders under the Voigtländer name. All of those products were discontinued last year, sadly.

As far as I know, the F6 is the last one still in production.

Should a person not be impressed by being able to travel through two miles of incredible urban density in just a few minutes?

I think vehicular traffic is far and away the most depressing aspect of NYC. All of the noise, pollution, bad attitudes, and danger to pedestrians and cyclists and it's not even close to being a timely and efficient way to get around. The subway is a damn miracle compared to any other current form of surface transportation.

Another mixture (that I admit I don't understand) is baking soda with hydrogen peroxide. It obliterated a close range direct hit skunk spray on my jeans and sneakers with a 20 minute soak.

I think it's an interesting project. That's enough for me to consider it useful, or at least not worthless.

They used to be made in the same city as the factory in the article.

Good simulation, I guess...

In NJ there's a restriction from hunting within 450 feet of a building. In Idaho that's probably laughable, but here it leaves a lot of space where you can't discharge any weapons.

There's a parallel with the charge that the "Drug Free School Zone" laws discriminate against minority communities because everywhere you go in cities, you're within 1000 feet of a school.

I was just reading about Swedish prehistory and there was mention of a drastic climate cooling period.

It's not a simple solution, because it's not very effective. In areas with limited open space, hunting is very much an exclusionary activity. In Staten Island, the NYC Parks Department is performing an experiment in deer sterilization: https://www.nytimes.com/2017/09/22/nyregion/deer-vasectomies...

It worked on me, I'm looking forward to buying the book. Is this the first time you've come across an excerpt teaser on the internet?

I used to use a 200mm lens with a reversed 50mm on a Nikon D70, and the focus is difficult. It sounds like the photographer here is using a sort of "spray and pray" technique and using focus-stacking software later.

You actually don't need the telephoto, though. You can get a reversing ring that mounts a prime lens directly to the camera. I took this using a 50mm lens on a full frame body, no focus stacking: https://c1.staticflickr.com/1/498/19387253482_cfdb183b3a_c.j...

If you use a shorter focal length lens, you'll get a higher magnification. I've used a 28mm in the past but wasn't very happy with the image quality.

Same with the 2011 Virginia earthquake!

I'd rather see a comparison between two 30-second exposures at 1600 and 6400 than what was presented here. That would give a much better idea of how much detail you're losing from sensor gain.

Can I ask how old you are? Non-judgmental, I totally identify with you.
