Why Three Views are Necessary

Why Three Views are Necessary

We live in a three-dimensional (physicists may say four, fantasists say more) world. To visually represent that, one needs to meld length, width, and depth. Absent any one and the result is a bizarre view of the world.

Hence, we can start with something as seemingly complex as this flat, 2-dimensional—up and down, left and right—drawing . . .

And get something that looks a bit more real-worldly with not only left-right, up-down, but also front-back.

What if one dimension is missing?

Archaeologists, historians, and other scholars have for years been wondering what the Confederate submersible H. L. Hunley really looked like. The historic vessel was discovered a number of years ago, has been raised, and is currently under minute excavation and discovery in Charleston, South Carolina. Many questions have been answered, especially what she looked like. (https://hunley.org/) Here is a link to the most recent detailed (extremely!) analysis of the vessel by the Underwater Archaeology Branch of the Naval History and Heritage Command. (https://www.history.navy.mil/research/underwater-archaeology/sites-and-projects/ship-wrecksites/hl-hunley/recovery-report.html)

But before this, to envision the boat, historians had to rely on a written record, no known photographs exist. There were a few sketches and one watercolor wash painting by R. G. Skerrett, which gave a fair idea of her form, but they—as is all art—were reliant on the artist’s eye and especially, hand. What is real? (Naval History and Heritage Command)

One of the early references was this two-view tracing of a predecessor boat, the “Rebel Submarine Ram” Pioneer. It was from a contemporary 1864 Civil War report from U.S. Navy Fleet Engineer William H. Shock to the Assistant Secretary of the Navy. (National Archives and Records Administration)

The upper drawing shows a side view of the ram, with some interior details. The bottom drawing shows a top view looking down of the vessel.

There is nothing, however, to show us the third dimension, a front view. The illustrations below will demonstrate the impact of that missing third dimension.

All the views you will see were made with this set of lines that I pulled from the original drawing. The only thing that is different between the pairs of renders is that in one, I let the original drawings determine the final shapes, and in the other one I assumed the third dimension to be curved.

These are the top views of the two versions, the lower has many more lines because those are necessary to draw the curves in the 3D rendering of these lines. Note however that the external lines of each part are identical. This reflects the lines’ origins from the lines pulled from the original.

This shows  the resultant 3D render.

Similarly, here are the side views, again with the lower drawing and render showing the addition of curved lines.

And this drawing shows the resultant third dimension, the front views, based on the base (left) and curved lines.

Here are the resultant images in full 3D.

Note that, both 3D renderings match the original 2D drawing. Which is correct?

While that is certainly obvious, this is just an illustration of issues that can occur in the absence of information.

This rendering further illustrates the need for three views. Notice the two highlighted areas.

Many times with all three views provided, even that information is not enough. Sometimes it is a confusion on the part of the original craftsman with regard to how a particular line should be depicted in each of the three views. More often, however, lines are hidden. These require either additional drawings, or better yet, a perspective drawing of their intersections. No examples come immediately to mind, but I am certain at least one will crop up on an upcoming drawing. I will address that when it happens.

This final rendering shows the curved 3D version over the original lines. The other version would similarly line up.

 

 

 

 

 

 

Photography as Photography

Photography as Photography

Thoughts on viewing a photographic exhibit at the Everson Museum of Art

First off, so you know where I am coming from, I have been a professional photojournalist for more than 40 years. That means I’ve gotten my hands wet with chemicals, mixed my own chemistry, got really sick from licking a ferrocyanide brush, and placed the Hand of God between many an enlarger lens and print-to-be. I’ve had six years of college education in photography and journalism, and another ten years or so apprenticeship under some of the world’s greatest unknown photographers.

My photography has always been nuts and bolts. Four to six assignments a day, and at times many more, spot news when it happens and all with a deadline looming overhead. Call it photography’s version of meatball surgery. So although I had six years of learning, working, and honing the niceties of the craft (operative term), my profession called for a lot of short circuits to deliver a photograph to the daily doorstep. Fact: some negatives lasted no longer than the first printing. They were processed so fast that the first exposure to enlarger light killed them.

All this is a long way of saying I know a little bit about photography.

My slice of photography is recording the moment. It is not the “moment” that high cotton photojournalists describe and write books about. My moments are that 1/125th of a second of someone’s life and the 30-second exposure of a snippet of a city’s life. At Syracuse, my fellow neophyte shooters would discuss their “style.” We would talk of the masters—Cartier-Bresson, Weston, Eisenstadt, Stieglitz, Smith, Lange, Capa, Feininger, Adams (Ansel, not Eddie), Cunningham, Penn, and the then young guns such as Mark, Erwitt, Winogrand, Warhol, and many others. After six years, I left school with no style in hand. I was a loss. So I went to work. It was only after about five years I discovered I did indeed have a style, but it wasn’t quite a style. It was a philosophy.

I came to have a deep rooted faith in the camera as a tool to provide the single most important, accurate, and—if you will—perfect record of a specific instant in time. Regretfully—very regretfully—I now have to include the phrase “in the hands of an ethical person” to this belief. When that shutter clicks (or used to) everything within the four walls of the (then) film frame were captured for all eternity (if the black-and-white film was properly processed). As a photographer, I was an instant historian. Over time I came to see that in everybody’s photography, not just those of us who were paid for having the fun and excitement of that process. Indeed, as a columnist, my mantra was for everyone to dig out their shoebox archives—for that was the storage medium of choice for negatives and prints—and preserve and share them with family members to identify as fully as possible names, locations, and situations. With the passing of each generation, those very salient pieces of information so critical to the significance of the image are lost forever.

The bottom line of all this is photography is an art and a craft. It is very much akin to baking. A negative needed to be exposed to a specific amount of light for optimum image capture. It then needed to be processed at a critical temperature for an exact amount of time to have that image properly developed. It further required critical steps for “fixing” the image against further light exposure and its permanent preservation. Similarly, the print required the same critical steps. Any deviation from time and temperature resulted in a less than optimum image, which is readily apparent to one who has walked the walk.

So this distills to an image that looks like what the photographer saw.

This brings me to an exhibit I saw this past weekend at the Everson Museum of Art in Syracuse, New York. This is not to be seen as a condemnation of the Everson or the artist. Just an observation on my failing to understand the artist’s communication.

This is the display. It is an amalgam of numerous photographs, approximately 150, on an approximately 62 1/2-feet long, by about 18- to 20-feet tall wall. Each of the prints was about 5×7 inches.

As individual images, there was no craftsmanship displayed. The image quality was poor, at best. There was no evidence of individual treatment. Most of those that I could see—for it was absolutely impossible to view those that were mounted more than eight feet or so above the floor—were snapshots; i.e., they had no discernible composition or point of focus. Subject matter was all over the map: a wine rack, a shop front, a pair of nude men, footprints in sand, dirt. There were groupings of two, three, or more images, again with no seeming relationship.

The artist also appeared to have little care for his/her presentation as image borders were not completely trimmed (see red box).

Art is a tremendously important and effective means of communication. That process, however, to be successful, has five basic elements: the sender, the message, the medium for transmission of the message, a recipient, and feedback from the recipient to the sender. The lack of any one means communication has not occurred.

This is a failed communication. What is the message? We can identify the sender (artist), medium (photographs pasted on a wall), recipient (museum visitors). Feedback is also easily determined—what the hell am I looking at? And why am I looking at it?

Don’t Waste Your Money or Time

Don’t Waste Your Money or Time

Bambari How to Draw and Paint Aircraft Like a Pro

you could try this out by Andrew Whyte

Zenith Press, 2008. 160 pages.

 

This is the first book I have ever purchased that I feel to the core was simply a waste of money. If I didn’t abhor book burning, this would be a pile of ashes in my backyard.

The title would lead one, or at least it led me, to believe that there would be tips, tricks, and techniques. That belief was wrong. This is all about hawking the author’s work.

I never like to leave a book with a bad thought, so my happy thought for this one is that it looks good. If you want to look at it, go ahead. But looks only go so far.

Good but overpriced

Good but overpriced

Gemini (Space in Miniature, Number 2)

By Michael Eastman and Michael J. Mackowski

Space in Miniature, 1990. 36 pages.

 I got what I expected.

The overprice is because of the publication’s rarity and not based on an expansive and detailed presentation of the spacecraft’s physical details.

Designed for modelers, it touches all the bases. If you are building a Gemini capsule, this should be about all the info you need. You will have to balance cost vs. value.
