Saturday morning fun: Photography thread!

Let's have fun with different lenses, zoom, and framing!

I'll quickly teach how lens and focal length can make a huge difference.

#photography

1/ This is the view from my balcony, (i love #Vancouver !!), and we're not gonna leave here, but our lesnes will take us all over. At 70mm, this is about "what the eye sees" in terms of zoom and detail.

2/ Just panning to the north intersection, uhoh! Fire trucks are here for an incident!

3/ To the south, Granville Island and the Sunset. We're gonna have some great photos here. At 70mm, you can really capture the "whole scene," without making the viewer feel small or insignificant.

4/ Let's walk through zoom levels, so you can see how camera lens and focal length can REALLY CHANGE the types of photography and scenes you can capture.

Let's ZOOM OUT.

5/ At 14mm, we're basically "ultra-wide-angle." This can be really helpful for landscape (realtors can use it to make rooms seem bigger, because it really stretches out the corners). In exteriors, however, it makes everything seem small.

6/ At 24mm.

You can see the fire trucks... I guess... but without the framing of a zoom, there is nothing to draw your eye there. Basically, it feels like just another city shot, despite there being a CAR THAT WAS ON FIRE in the intersection.

7/ 50mm is often called "the nifty fifty" because of its versatility. It's great for portraits, landscapes, urban shots, and pretty much everything in between, and the lenses are often the smallest and most portable.

Check out the variety of what you can do at 50mm:

8/ Let's start zooming in, where *Framing* (making sure the thing you want highlight is properly placed in the photo) becomes important.

This is the sea at 150mm.

You can't even see any buildings, and I've hidden all of my balcony obstructions. Right down the middle.

9/ At 200mm, I start to be able to choose to focus on very specific subjects in the distance. Looking out to sea, I can choose between the penninsula or the open ocean. Here, I chose the penninsula.

10/ At this zoom, I can more easily draw your eye precisely to the thing I want you to see. It's pretty hard to not see the incident now!

11/ At 400mm, I actually have to choose! Do you want to see the car that was on fire? or the fire truck?

12/ 600mm!

Now this is when you can be creative even from one point. The next photos will all be from one spot on my balcony, at 600mm, fully zoomed in. Each has its own focus and theme, and I can completely direct what is framed and what your eye will see likely be drawn to.

14/ "Stop Speeding, You Don't Look as Cool as You Think"
by Tyler Black, 2021

(and yes, he was significantly speeding, and yes, at 600mm I fully have his license plate information)

15/ "Sing me a Shanty"
by Tyler Black, 2021

16/ "The Gull that Thought it was an Eagle"
by Tyler Black, 2021

17/ "I'm Sure I'll Go Tomorrow"
by Tyler Black, 2021

18/ "I Could Bike to Work Too!"
by Tyler Black, 2021

19/ "In Flight" (this gull was about 1.2km away!)
by Tyler Black, 2021

20/ "Oh Canada"
by Tyler Black, 2021

21/ "The Shore"
by Tyler Black, 2021

22/ "The Loop"
by Tyler Black, 2021

23/ For all you photographers out there, get creative with those zooms! Use your lens as a tool to frame your subjects, and recognize that there are always opportunities to work on this hobby :)

Share YOUR favourite zoom/lens differences with me! "same spot, different look"

2020 US Suicidology Update:

3 new states (HI, ND, NJ) have been added to the total, all showing decreases from 2020. I added Cook County IL (oct-dec) to the list and removed Howard, IN, though its in final calculations. To keep the list down, I have to sacrifice small for big.

1/ At this point, my scan has captured almost 87M person-years, about 1/5th of the US. Because it is a nonrandom sample, it can't yet be used to estimate, however, the skew is on and clear - no major increases in 2020, most states and counties showing decreases.

2/ There are no surprises at this point - we are seeing clear and consistent trends across the nation.

It is with fairly high confidence that I repeat:

"The data does not support an increase in suicides in the US during 2020, in fact, if anything, it supports a decrease."

#Bullying Thread:

It's #PinkShirtDay2021.

Let's do some teaching on bullying!

Some people who could help will wear the #pinkshirt on this day and do nothing else.

Even worse, many bullies will wear them.

To reduce bullying we actually need **to do substantial things**

1/ Bullying has 4 main components:

First, it's between peers, but an imbalance exists (socially, physically) between these peers.

**This is important.**
Teachers can't bully kids, that's ABUSE.
Bosses can't bully employees, that's ABUSE.

2/ Second, bullying is designed to cause harm or fear.

Third, bullying is repetitive, and the repetition further enforces the imbalance that already existed.

Fourth, it is an attack that can be physical, verbal, psychological, or social.

Suicidology 2020:
Subgroup analysis (youth, sex, race)

I was able to access a data set from a Cook County, Illinois. Cook County is home to 5.2M people and includes Chicago.

It's the 2nd largest county in the US
/cont

1/ In total, there were 438 suicides in 2020 in Cook County, compared to an average of about 480 in the past 3 years. During the pandemic spikes, suicides decreased.

All in all, it was a below-average year for suicide deaths.

2/ Black residents died by suicide at a much higher rate (42% increase). This increase was occurring before the pandemic as well. During the first wave of the pandemic, it worsened, second wave it lessened.

A much higher year for Black suicides: 97 vs. an average of 68 in 5y.

Friday Update for Suicidology Data/News regarding 2020:

We have new data on Oregon has layers of detail. Suicides overall in 2020 were down 10.6%, from 910 in 2019 to 820.

(recommend you assume Nov goes up a slight amount, dec a little bit more, and Jan significantly)

/1

Importantly, more evidence to the pile that the reporting on suicide presentations to the ER are MISQUOTED and MISATTRIBUTED. It is generally not true that presentations are up (both nationally and at state level data).

/2

Here, suicide presentations to the ER dropped off and overall were lower than 2019, but not as severely as visits for other reasons, making the *proportion of visits higher*. So it is not true in Oregon that "presentations for suicide were up".

@CDCgov

I am glad so many are seriously considering suicides in school-aged children as more than just about "mental health."

Recognizing that school may be a factor in youth suicide is very important.

Here's 1999-2019 in America, prior to COVID.

Source: @CDCgov

Let's make sure we don't pretend that we will solve the problem of youth suicide by "getting back to normal."

We will all need to continue to focus, on a national level, to our children's wellbeing and work to remove stresses, barriers, stigmas, and structural inequalities.

As any person who works with kids in an emergency department, mental health centre, crisis call centre, or psychology/psychiatry department will tell you, school and its surrounding stressors are a MAJOR CAUSE of youth distress.
