The Humboldt Exhibition Moves Online

Curator Eleanor Jones Harvey had completed the years-long task of gathering the art and artifacts for her Smithsonian American Art Museum exhibition about Alexander von Humboldt, which was scheduled to open in the spring of 2020.

Frederic Edwin Church, The Falls of Tequendama, Near Bogotá, New Grenada, 
1854, oil on canvas 60 7/16 x 48 1/16 in., Cincinnati Art Museum

Then the pandemic lockdown happened.

When the date was set for the staff to exit the building, she knew she might not be able to visit it again. So while she still had access, she had a brainstorm: why not document the show with a curator's tour? 

She found a videographer. Without time to prepare a script or dress up for the occasion, she did an off-the-cuff video walkthrough of the exhibition. 

It's an inspired presentation: coherent, eloquent, accurate, and concise, especially when you realize how spontaneous it was.   


The curators and education team produced videos and images for an online experience, which you can still see on their website.

One of them is a video focusing on Frederic Church's "Heart of the Andes." The video separates spatial layers and uses lateral parallax movements to create "an immersive journey."

Imitation vs. Representation

 

"Forsythia is pure joy. There is not an ounce, not a glimmer of sadness or even knowledge in forsythia. Pure, undiluted, untouched joy." —Anne Morrow Lindbergh


A plant like this forsythia is more than the sum of its flowers and branches. I have to invent a toolset of brush techniques for describing characteristics of the flowers, both in terms of the overall mass and the granular detail.


Complete imitation of every flower on a forsythia plant is probably not possible or even desirable. We have to recreate or represent the characteristic detail rather than imitate it.



Asher B. Durand, in his influential 1855 essays "Letters on Landscape Painting" draws this very distinction between imitation and representation. When painting something as complex as a tree, he says, “direct imitation is impossible." Instead the artist should strive to “represent this foliage in every essential characteristic, without defining the forms of individual leaves. To do this, some analysis of its structure is necessary.”

Painting Forsythia Flowers


I paint the flowers of a forsythia shrub using a limited palette of watercolor and gouache. I show how to start by capturing the overall gesture and silhouette of the whole plant and then subdivide the mass into smaller shapes.

Combining Pencil and Oil


 

Our boat brought us to a settlement of crested hadrosaurs and their human assistants, where we spent a few days drying out in the smoky attics of their houses" 

The painting is done in oil wash over pencil on illustration board, which has been sealed first with some workable fixative spray and then with a thin layer of acrylic matte medium. 

Dinotopian flight instructor Oolu holds a lightweight skybax saddle. 

This technique is fast, direct, and reproduces well. 

handeyeoriginals asks: "What do you thin the oils with to make the wash?"

Answer: Liquin (a fast-drying alkyd medium) and Gamsol (a mineral solvent). Note that both of those are toxic, so you need good ventilation and protection for the skin of your hands.

    joeybruceartWhat’s the advantage of an oil wash instead of watercolour?
    Colour? Vibrancy?

    Answer: It's workable for a longer period and it blends well with opaques.

Colexification

Colexification refers to a method of mapping the meanings of words.
 


All languages have words for basic emotions like love and anger and shame, but the words may not convey the same meanings in different cultures. 

This way of mapping visualizes the proximity of related emotion words and the connections between them.

These maps are used by scientists to speculate about whether the emotion concepts are genetically coded or are culturally disseminated.

Text Driven Manipulation

Suppose an art director looked at one of your pieces and said "Great, but could you make it more goth?" 

You'd know what to do, right? How about taking a cat picture and making it more cute or changing a tiger into a lion?

Computers, using large data sets, can accomplish such manipulations. In the top row of each pair is the input image. Below that is the manipulation. The phrase is the text prompt used to drive the manipulation.

The Lap Box

Eugen Dücker 1841-1916 painted this portrait—possibly a self portrait—in 1900, showing a portable lap box rig used frequently by plein-air painters at the time.  


The artist sits on a tripod chair with a wooden box open and the painting pinned or propped on the inside of the lid. There also seems to be a white umbrella folded up on the ground next to him.

The arrangement has several disadvantages: you can't easily stand up or back up from the work; the size of the painting is governed by the size of the lid, and unless you have slots cut into the top frame there's no easy way to store wet paintings.

How Do Our Brains Process Images—Decoding or Predicting?

For a long time, scientists believed that images were decoded in a bottom-up process.

It was thought that the image arrived on the retina and was sorted out in stages, starting with edges and shapes that were then assembled into recognizable objects, faces, or symbols by specialized areas of the brain.

You may recognize what this image represents just from the top of the picture; you may even guess who painted it.

The alternate way of understanding visual perception is the top-down predictive model. This idea suggests that the brain contains a stockpile of representations of reality that it imposes on what you see. You don't really see reality directly; you see your brain's prediction of what's in front of you. 

According to neuroscientist Andy Clark, "the brain is essentially a prediction machine." 

Most scientists agree that these two systems interact at various stages. Bottom-up constructive image processing meets top-down prediction throughout the hierarchy of image decoding from the most basic to the most sophisticated. 

This process moves like greased lightning until you run across a prediction error or an ambiguity.

Green lines are equal. Source

Optical illusions present anomalies where the top down prediction comes into conflict with the bottom-up construction. Sometimes this conflict happens at relatively basic levels of processing, creating estimation errors of perspective, shape, or overlapping.


This skull illusion creates an ambiguity of interpretation at a higher level of interpretation. 

It's good for us as image makers to be aware of how our eyes and minds work as we decode the world around us and reconstruct it for the enjoyment of others.
