More Photography Updates

Read Time:2 Minute, 28 Second

With the realization that I’ve been doing it wrong, I’ve completely revamped my approach.

First, now that I truly understand how Dynamic Range in a Fujifilm camera works, I am shooting in DR-Auto again. As a practical matter, that means my images will be DR-100 or DR-200; I’ve never seen the camera select DR-400 on its own. Note that, when shooting night scenes with bright subjects (fireworks), it may still be necessary to shoot DR-400; I’d rather underexpose the shadows than overexpose the subject.

Additionally, my current generation of recipes and the two of the prior generation I kept have a few fundamental changes. First, I am setting my highlights and shadows explicitly, versus setting them to 0 or even -2. Second, I am no longer using Auto WB. Six of my current recipes are using either Daylight or Shade. One, that is still somewhat experimental, is using temperature.

The net effect of these changes is that I am seeing a more “filmic” look in my pictures. That’s one of the reasons I chose the Fujifilm ecosystem, and this is therefore perfectly fine with me.

And now for something else that I’ve recently discovered.

Exposure vs “Brightness”

I’ve been approaching exposure in the wrong way. I have no idea if this terminology is correct or not, but for lack of a better word, I’ve been confusing exposure and “brightness.”

Exposure is the amount of light allowed to hit the sensor and is a factor of a few things, including aperture and shutter speed. What I am calling “brightness” is a combination of exposure, highlights, and shadows. Because of this confusion, I have been adjusting exposure compensation to account for the amount of highlights and shadows, and this is contributing to over- or underexposed images.

I discovered this by observing the relationship between exposure compensation in the raw image and the Push/Pull setting in Raw Studio. I found that, by backing out my exposure compensation by adjusting the Push/Pull by an equal amount in the opposite direction, I can generally produce properly expose images without having to change my highlight and shadow settings. That is to say, if I shot the picture with an EC of +1.3, changing the Push/Pull to -1.3 restores a proper exposure.

Careful use of the EC feature in the camera is important in order to avoid irreparably over- or underexposing the pic.

To be sure, certain high contrast settings might require adjustments, or even force me to edit the raw in darktable. However, the effect of all these changes and careful attention to exposure has allowed me to start shooting raw+jpeg again, and I am rediscovering the fun of photography.

I still need to update the settings for Cleancros and actually write the settings for Eternaty. I also have five new recipes to document, all developed around the highlight, shadow, dynamic range, and WB changes I described above.

Lord, I’m terrible at keeping this site updated. Granted, for the last 10+ months, I’ve been a student at Western Governors University. I’m pursuing a Master of Science in Information Technology Management. I’m at the end of the program, and I’m about to have a lot more time on my hands. Let’s see if I can do better.

Using ILINet to track COVID19

Read Time:2 Minute, 12 Second

In my first writing on the COVID19 Pandemic, I mentioned that flu surveillance can be used as a way to track the spread and severity of COVID19. Let me take you through some of what appeared in the Week 12 edition of FluView (the CDC’s influenza surveillance product). I originally wrote this on Twitter.

This first image shows the prevalence of influenza-like illness (or ILI) present in the country for the week ending March 20, 2020.

It shows flu-like illness is elevated across the country. The percentage of visits for ILI is almost to the levels of the peak of the current flu season, and the amount of confirmed flu (positive tests) is way down.

This next map shows the ILI activity in each state. Keep in mind that we are late in the flu season, and we are past peak. The map is ugly; it shouldn’t be so red. I also do not know why Florida is showing low levels of flu activity. It should be much higher than that. Perhaps the data is lagging.

More troublingly, perhaps, is that pneumonia and influenza mortality (P&I) was above the epidemic threshold for week 11, the week for which we have the most recent data. Since the CDC does not count the number of flu deaths (except for children), P&I mortality is one of the proxies used to determine that.

At this time of year, P&I mortality should be leveling off and then declining. This uptick could point to COVID19 deaths that are not being reported in the official case counts due to inadequate testing. This is one of the metrics that will be used to estimate the actual number of deaths once the epidemic is over.

I want to stress that the official case counts are far smaller than the number of actual infections, and the number of fatalities are as well, though I don’t think either can be quantified at this point.

I will continue to monitor FluView and see if it shows us anything that might be useful in determining if social distancing measures are helping.

Note that I am not a doctor, virologist, epidemiologist, or any other kind of expert. Infectious disease has long been an interest of mine, and here I am simply applying my interpretation of public data.

A future post may talk about what we know of serious illness in young people, including the prevalence of acute respiratory distress syndrome (ARDS). We seem to be seeing quite a lot of that, and but for modern medicine, we would probably be seeing a much different type of mortality.

Armistice Day

Read Time:10 Minute, 53 Second

In the United States, November 11th is celebrated as Veteran’s Day.  In much of the rest of the world, however, November 11th carries a different significance.

On this date in 1918 (98 years ago as of this writing), the armistice that ended WWI was signed at Compiègne.  WWI was, perhaps, the least logical and most preventable war in the modern history of the world, and yet it was fought, and produced misery on an unbelievable scale at that time.  Sadly, part of its legacy was WWII, which increased the human suffering from war still further.

He Was A Great Guy (Texas and Red Dirt Country #4)

Read Time:12 Minute, 19 Second

Back on Tuesday the 17th, we lost visionary singer-songwriter Guy Clark. He was a huge figure not, only in Texas and Outlaw Country, but also writing songs that achieved popular success with singers such as Ricky Skaggs, The Highwaymen, Brad Paisley, John Denver, Alan Jackson, John Conlee, and many others.

His catalog is quite extensive, and any tribute I could try to do would be inadequate to the task. Nevertheless, I will endeavor to put something together.

I have chosen five of my favorite Guy Clark songs. I could have added others (“Texas 1947″ comes to mind), but I do need to limit it. I have chosen “Desperados Waiting For A Train,” “LA Freeway,” “My Favorite Picture Of You,” “The Guitar,” and “Dublin Blues.” Continue reading “He Was A Great Guy (Texas and Red Dirt Country #4)”

I Are A Star (Texas and Red Dirt Country #3)

Read Time:1 Minute, 11 Second

This post originally appeared in BattleRedBlog as a FanPost.


For this week’s installment, we have a song from one of the big names in Texas Country as well as a major songwriter for Outlaw Country (including some of Waylon Jennings’ hits): Billy Joe Shaver.

He has had an impressive career as a songwriter, with the following titles to his credit: Honky Tonk Heroes, You Asked Me To, Live Forever, Georgia On A Fast Train, I’m Just An Old Chunk Of Coal, just to name a few. At some point, if I continue this series, I’m sure I will get to one or more of those songs. However, in this post, I have selected Slim Chance And The Can’t Hardly Playboys, featuring fellow Texas Country artist, Kevin Fowler. This song tells the story of a very bad band, the Can’t Hardly Playboys, until Slim Chance came along and “played the songs that stick right in your head.” That’s not necessarily to say he was any good either. The band continues to play in Walmart parking lots, for instance. They still dream of getting dressing rooms when they play. It’s a very silly song, with a number of puns in the lyrics.
