White Balance Does Not Work The Way That They Say, Maybe Not For You, Definitely Not For Me

It’s quite common for photography writers to write something like, “The human eye… adjusts the colors you see,” whenever discussing white balance. I never encountered one of these articles that also referred to scientific research, and I am unsatisfied with the explanation.

For one thing: it’s not consistent with anything that I learned in physiological psychology or psychophysics regarding vision.

For another thing: it is extremely common for scientific-thinking people to disprove much of what photographers teach.

For another: it’s not consistent with my personal experience, which is more like this:

I don’t believe that my “human eye… adjusts the colours [I] see.” I am very aware of color temperature. I suspect that most photographers develop this awareness, and some people have always had it.

When I am in an environment with soft white light, that’s what I see, but it’s everywhere. It’s even affecting the color of the photos on my wall. If those were white balanced, then the light from the too-warm bulbs is affecting the colors of those photos exactly the same way that it’s affecting everything else in the room, so it’s tolerably similar, but not changed by my eyes.

I left that as a comment on a Picture Correct article on white balance, and Wendy disagreed, but her rebuttal is not actually inconsistent with my comment above. She wrote:

Some say it’s the “eye” that adjusts, some say it’s in the “brain,” point is, you DO adjust to a “normal” WB. If you’ve been inside with a bunch of tungsten–especially low-light, like in a theater–and then suddenly go outside, the world will be blue-shifted for a few seconds while you adjust.

I make temari (embroidered thread balls), and I’ve got one that’s got a design in blue and three shades of purple. Thing is, in dim light, your eyes will try to convince you it’s red, yellow, green and blue–that you’re just seeing it in a different “white balance” than you really are.

She gives an example of an adjustment here, but I am not convinced it is. To me it looks like an example of becoming aware of the different colors of light, but I am always aware of them, and people that think about light will be too.

The “human eye adjusts” isn’t a scientific explanation, it’s an expectation. Photographers think about white balance this way, because that’s what they have been taught, but in reality, they do see three shades of purple as non-purple, because there’s no real adjusting going on.

That said: adjusting white balance in your image is important, because the colors in your photo are affected by the light that you are viewing it in, exactly as much as every other color that’s in that same light. Your photos won’t look “right”.

On the other hand, by all means: monkey with white balance in order to meet your artistic goals.

My KISS Story

(Originally posted on 2016-06-08)

I went to see KISS at the Glens Falls Civic Center in the 1980s. My seat was on the floor (where the hockey ice would be) way in the back, the seats in front of me were roped-off and watched by security. This kid walks up to the security guard and starts messing with him. While he is harassing the guard he looks at me and says, “What are you waiting for? Go!” So I go up to the stage.

When the concert starts I get crushed by bodies, but I know all these KISS songs, because I used to play them on bass; Robert Pulsifer, a guitarist, made sure that I knew them. So Gene is in front of me, and I am doing air-bass identical to what he is doing. All the people around me push back, and give me room (weird), and now I can really pretend to be Gene Simmons right in front of him. He is singing and watching my hands. Between songs they switch places, but before-going he leans over the bouncer pit and flicks his tongue at me.

That’s what KISS fans were like. They will crush you to get closer to the band, unless you need room. Also, they will mess-with-security for a stranger.

So that’s what a tank slapper is…

(Originally posted on 2007-06-21 as /archives/22)

I experienced my first tank slapper on 2007-06-20.  That’s when a harmonic instability causes the handlebars to swap from side-to-side as far as they can go (AKA full lock).  I purchased a Suzuki SV650SA7 one month earlier (2007-05-19), and I already have over 1200 miles on it.   Anyway, I was coming out of the parking lot on the NE corner of Iowa and 23rd in Lawrence, KS after lunch.  These cars were coming at me pretty fast so I wanted to accelerate out-of-there.  I gunned it while I was leaned over.  First the rear wheel starts spinning, or I hit a false neutral, or who knows what (VROOOOOOM), and then the handlebars are doing a high speed dance (JIGGY-JIGGY-JIGGY), and left foot comes of the peg.  Afraid?  HAH!  Danger is my middle name!  Embarrassed?  You bet.

Here is a video of a tank slapper that looked like mine:

Here is a much-worse-ending one:

Air to Air with Justin de Reuck 2014

(Originally published on 2015-04-12 as /archives/10278)

Here is Justin de Reuck’s website.
Here is Justin de Reuck’s Vimeo channel.

I used to take photos from small planes (many times) and a balloon (once). Most of those were lost. What do I miss the most? My images of the Thousand Islands.

What am I afraid of? Heights. How much? Terrified. Did I go up in planes anyway? Regularly. Nothing like this though.

How does he hold the camera when the plane is upside down? They are doing positive-g aerobatics, so it feels the same regardless.

Here’s Tex Johnston doing a positive-g roll in a 707:

Here’s Bob Hoover, poring an ice tea, while simultaneously doing a positive-g maneuver. Amazing:

Find Your Next Job Online: Even In A Recession

(Originally posted on Apr 20, 2009 as /archives/2531)

I had this experience back during the dot-bomb bust. Obviously I need to paraphrase here, because this conversation happened long ago.

By Tulane Public Relations (Career Day Uploaded by AlbertHerring) [CC BY 2.0 (http://creativecommons.org/licenses/by/2.0)], via Wikimedia Commons
Recruiter:

“How are you doing your online job search?”

I then describe how I search for positions via friends, Monster, etc.

Recruiter:

“That will never work. Those ‘known’ positions potentially have hundreds of applicants. It doesn’t matter how good you are. There are just too many other applicants.

Here is how I find potential applicants. One of my clients contacts me directly to fill a position. These are typically not positions that are widely advertised. My client wants to interview a small number of highly qualified people. I go to one of these Web sites (she then shows me Monster).

Then I search on the keywords that are in the job description, the potential applicant’s location, etc. Then I contact the folks on the first page. I am almost always able to fill the position for someone near the top of my search results.

So, the most effective way for you to find a position is to be on that first page. You don’t look for positions, because too many other people are applying for those very same positions. You simply position yourself so that I can find you.

See this? The results near the top were edited recently. Make a resume. Put it on here.

Put all the technologies that you know on it, and update it every single day, even if you simply add a space somewhere. Editing it every day puts it near the top of the search results. This advice will help other recruiters find you. In the meantime I will see if any of my clients need you now.”

Needless to say, this turned everything upside down. My job wasn’t to look for a job. My job was to market myself.


The advice above eventually generated many leads over the next ten years: long after I stopped updating my resume online. So this plan did work.

That said, you never know where your next offer will come from. I met a Walmart recruiter at a Diversity Job Fair during the dot-bomb implosion.

The Dallas Metro area lost over 78,000 IT and Telecom jobs during the 12 month period prior. Many of those folks were at this job fair.

There were two extremely out-the-door lines to the only two tech companies present, and a lot of empty booths for non-tech companies.

One of the tech companies was interested in applicants with flight simulator engineering experience. The other said, “Go to our Web site. We are not taking resumes.” O… K… I was near the start of the line, so I let others know what I learned, and I heard a lot of, “Thanks, now I don’t have to waste anymore time here” in response.

So, I introduced myself to a Walmart recruiter at her empty booth, because why not? She took one look at me and said, “I am not recruiting computer programmers. I am recruiting night stockers in Dallas for the holiday season.” I reply with, “That’s OK I was a Night Stocker at Ames Department Stores. I like retail, and I like stocking shelves. Also, I would like to move to Bentonville Arkansas to be a computer programmer.” She took my resume, told me that she would bring it home, and give it to a tech recruiter. That led to the highest paid position that I have held.

Multiple Shot Panoramas

(Originally posted on 2016-05-08)

We experience the world in ultra widescreen; that’s how our photos should look.

Can’t I use a wide angle lens, and crop the image to make a panorama?
You could, but you will loose a lot of
detail. Even a perfectly exposed and focused image will look grainy (or blurry), if you don’t have enough resolution.

I have a lot more to say about this, and I will mostly do so when I share my own panos. In the meantime, here’s Richard Harrington’s take, and some of my comments:
https://youtu.be/QMR6nnPoeZ4

Handheld Technique
Do this instead of bracing the camera against your chest:
1) Look through the viewfinder.
2) Use the grid lines in your viewfinder to align your images. Also use them to make sure that you have at least 33% overlap between images. This is easy to do with the 3 x 3 grid.

On Tripod Technique
The distortion created by hanging your camera off the side is very difficult to deal with. If you don’t have an L bracket, then, yes, keep your camera in landscape orientation, and use a wider angle lens.

Loud Parties, Playing the Bass

The guy below me (at 30 Larnard St, Potsdam NY, in the early 90s), had a loud party, and played metal and classic rock records, real loud. Did he invite me? No.

Kids: if you are going to have a loud party, then you always invite the neighbors. In most cases they won’t come, but they will appreciate it, and they won’t call the police. Here endeth the lesson.

So I invited myself by plugging in my bass amp, and playing along with all of the songs. He eventually turned it down.

Did that end it? Not exactly: this started to become a regular thing, but at least he turned it down much quicker.

So one day his girlfriend stops me in the store, and says, “Hey, you’re the guy that lives above us. Every time that we have people visit, my boyfriend turns up the stereo, and then lowers the volume so that he can show everyone how you play the bass!”

All righty then…

Amanda & Jack Palmer: 1952 Vincent Black Lightning

(Originally posted on 2016-05-05)

Amanda & Jack Palmer cover Richard Thompson‘s 1952 Vincent Black Lightning if this video. The video is quite good. The art is by David Mack of Kabuki fame. Watch it.

I was aware of the Dresden Dolls, but I didn’t start listening to Amanda Palmer until after she married Neil Gaiman, because: Neil Gaiman. I suspect that this true for many people. Most of her music is pay what you want so there’s every reason to buy it if you like it, and pay exactly what it is worth to you.

Here’s what a stock Vincent Black Shadow looks like. The image is by brett Jordan:
