A computer cheat defeated

In my previous post Judy wrote that may be using a computer amounts to a "cheat". She is right to a certain extent. Vermeer  and Ingres didn't have Photoshop. However, they *did* use devices. Click on either painter's name  to see what they were up to.

But just as an example. The other day I visited the Huntington with my dear friend Molly Lipsher. While we were there, a painting caught my attention. I am not particularly fond of it, it's very nice and all but what attracted me to it was the subordination of the whole painting to one note of very saturated color. This is exactly the kind of thing a "garyscale map" in Photoshop might not resolve if taken from a photograph.

Here is the original "The Last Gleanings" by Jules Andre Breton.

And here is the Photoshop treatment of the painting as I explained in my posting before.  In the grayscale version you would never guess the prominence the red sun in the real painting. The chromatic saturation stands out more than the tonal value so while the whole painting hangs on that touch of red ,tonally speaking, it's not even an accent.

Ah, but that's not all there is. In the image bellow I used the "levels" adjustment in Photoshop to eliminate all the middle and low reds, basically leaving only the top saturated reds. Not surprisingly, the sun glows now  like a traffic light. Sold!

Values made easy...with the computer.

How do you manipulate images in the computer to obtain a grayscale tone map.
It is very easy in Photoshop or any other paint package with similar functions. You can do this to any image you want to paint to aid you in discovering the true tones or families of related tones.

Let's start with a random image. Here is one of a Motel in L.A.

It is a not a very complicated image but it can be tricky to determine  what are the prevalent tonal values just by looking at it.


First , let's discard the color.
Image > Mode > Grayscale (discard color info , yes, but do not save the image over the old one)

Second, let's posterize . There are infinite ways of doing this.
Posterize just removes all gradations and returns an image with the amount of levels you specify.
Image >Adjustment> Posterize (level 3)

Because it's a little grainy, let's blur it a bit.
Filters>Gaussian blur.

Fourth :
Posterize yet again

And there you have it.The Motel reduced to grayscale. I bet you didn't guess the sky was closer in value to the asphalt.

Preconceptions as teachable moments.

Except for a few boy and girl geniuses, we've all asked silly questions at some point or another. Actually, it is true there are no silly questions except when they are repeated . I saw a funny t-shirt that aimed to answer common questions asked to plein air painters from people that walk by and have the blessed curiosity to ask.  This got me thinking about innocent, annoying or just plain repeated comments  uttered by painters and workshop attendees. Many of them based in preconceptions.   I've made similar comments so this isn't meant to embarrass anyone. It's about seeing the humor in their recurrence.

SOLD IT! Gone to a good home.
All in capitals. Like the ding ding ding of a casino slot machine. While sales are a wonderful validation and it is so very  hard not to share your success this has to be the worst offender on Facebook.  At least I find it a bit off, may be I'm wrong.  Unless you are a gallery owner  showing off your market prowess or the lucky seller is taking us for dinner I wonder what  purpose loudly announcing sales really fulfills.  Is it just just braggin'?  Creating the impression that you better hurry or you'll miss out if you are a patron?  If the announcement is accompanied by the  actual monetary value, I'd say that would be great information, I am not advocating any sort of  "discrete classiness", being an artist is a business too. This business aspect of being an artist interests me greatly, what about sharing your business plans? What about sharing your struggles, monetary or otherwise? Now THAT would be worth reading abbout.  As for the "good home"...what are you selling...puppies? You know you'd sell a painting to a mafia overlord/lady  if he/she came knocking.

What colors did you mix to get that color?
The eternal search for the recipe. It takes time and color charts to know your colors. Moreover, a color is meaningless unless another color sits beside it. The same grey can be a shiny green in one canvas and a neutral mud in another. While color mixes can be interesting, it is not a paint by numbers world. The formula that makes a good painting for one is the kiss of death for another. That's why we practice incessantly.  
Similar to this is the issue of  priming colors.  "I always prime my canvas bright red (or any other color)." Self-imposed habits and rules are great but there has to be a why behind them. Similar formulas abound. For example:  "Adding people sells paintings.".People and human figures add a certain scale and narrative accent to paintings of landscape. But like highlights on a glass bottle, the more you abuse this formula, the more you start to rely on  it and things go downhill in a hurry. People, highlights, they all  are compositional elements, not something to be "added" to guarantee sales.

"I hate to paint cars/cows/people..."
I think when people say they hate painting something specific like cars what they really are saying is: "I don't know how to see cars as a painter yet, I still see them as things and not as light and shadow." This is actually a great opening for teaching.   Of course our hearts go to certain subjects, cats, flowers, women, banks on fire, the devil in high heels... but the "hating" of a subject or its difficulty lies within the painter's knowledge or experience of painting itself, not it's inherent beauty. A scene can be complex or simple but the objects in it have very little to do with  whether they would make a good or a bad painting. The other side of this is that the public has similar prejudices and might not go for   a superior painting based on subject matter alone. Similar to this : "The light at noon is too flat". "It's not sunny so I can't paint."etc...

Do I need to know perspective.
Yes. You do. Especially if you are going to paint buildings, interiors, even still lives . The good news is that painters don't need to calculate orthographic projections like a scenographer  would or cast shadows mathematically. The perspective you need to know as a painter is very easily understood but nevertheless essential. Where's your horizon, your vanishing points, your choice of p.o.v....done.It's hard to teach this on the field but it's the perfect homework assignment. Same thing with anatomy. We need a certain level of  anatomy education to paint the figure.

"I'm just experimenting. "
A failure is a failure, not an experiment. Nothing to be ashamed of..Failure is expected, even desired. An experiment limits the variables to test an unknown outcome but has a purpose. An experiment requires preparation and method. In other words, an experiment takes even more time and effort than just humming along.  A train wreck is not an experiment. Move on.  to the next painting or try hard to figure out what went wrong and seek advice. Failures can be as powerful or more than great paintings if we don't dismiss them as experiments.
Similar to this : "I need to finish this painting" and the very famous "The light changed so (my painting went south)" Start a new one and don't linger. It's the light changing that makes painting outdoor a challenge . Commit to a light situation and memorize it. Can't use that as an excuse.

I didn't bring  sun lotion. It's your skin.

A book to go with it.

In anticipation of my solo show I decided to squeeze some time to make a small book showing a bit of everything I've been up to in the last two years. I am happy with it even if I might modify it a bit now that I have it in my hands.
