Canon setting the AF and Drive modes

In the past, auto focus <AF> did the job, but I had to click and recompose numerously to get the focus at the location I wanted.

Now, I choose to practice using manual focus <MF>! In cases when autofocus fails with special subjects that are difficult to focus, I will be adept at getting the job done. One new thing I learned is that when you manually focus while pressing shutter button halfway, the focus indicator lights up when focus is achieved.

That being said, having a strong knowledge of the AF system seems to be essential in sports photography, where the subject moves at an unpredictable speed and rate; a fast and accurate focus lens may capture that once in a lifetime action. Thus, I made Anki flashcards on chapter 3 of eos 5d camera instruction manual, which you can download here > canon::AF and Drive Modes

Note: deck excludes topics in AF sensor, lenses and usable AF points groups A-K, customizing, and AF micro adjustment.

If I were to pick 1 diagram to practice muscle memories with, it will be this.

History of Psychiatry

Intro: What are the pros and cons of Psychology and Psychiatry? How can we integrate both models into one?

Depression, one of the leading cause of blah blah blah, dates back to ancient Egypt 1550 BCE. However, the new psychopharmacology is a very young discovery.  History has proven that we humans, regardless of intelligence, wealth, power, are prone to make mistakes that have drastic consequences on society for years to come. For example, look into the Salem witch trials in 1724, the discovery and treatment of Drapetomia (disease causing negros to run away) & Dysaethesia Aethiopica in 1851, the development of lobotomy that won Nobel Prize in 1949, and DSM’s declassification of Homosexuality in 1973, as well as Gender identity disorder in 1980. 

Without further ado, here is the timeline and the key players.

we shall conclude this blog entry with an excerpt from TedTalk by Andrew Solomon:

The opposite of depression is not happiness, but vitality. Anxiety is the feeling all the time, if you have if you’re walking and slip or trip and the ground is rushing up at you, but instead of lasting half a second, it lasted for 6 months. Its sensation of being afraid all the time, but not knowing what it is that you are afraid of. Is depression a chemical problem or psychological problem? Does it need a chemical cure or a philosophical cure? I do not know. Maybe we are not advanced enough in either areas for it to explain things fully, the chemical and psychological cure both have a role to play. Depression is something that was braided deeply into us that there was no separating it from human character and personality. The treatments we have for depression are appalling, they are not effective, extremely costly, carry innumerable side effects, they are a disaster. But I’m so grateful to be living now and not 50 years ago, when there were almost no treatment. I hope that 50 years from now, people will hear about my treatments and be appalled that anyone endured such primitive science. Depression is flaw in love.…But the truth lies. Delusional perspectives….“Well, that’s west african and we’re in east africa, and our rituals are in some ways very different, but we do have some rituals that we have in common with what you are describing….We’ve had alot of trouble with Western mental health workers, especially the ones who came right after the genocide… they would do this bizarre thing, they didn’t take people out in the sunshine where you begin to feel better. They didn’t include drumming or music to get people’s blood going, they didn’t involve the whole community. They didn’t externalize depression as an invasive spirit. Instead what they did was they took people one at a time into dingy little rooms, and had them talk for an hour about bad things that had happened to them.”
