In my last blog entry I talked about how the computer world has revolutionized the designers and illustrator’s work environment and, as I announced, today I would like to make a comparison between all time analog tools and digital ones. As I said in my former post, in the digital world there are still some important limitations for the artists taught in the analog world. Especially in terms of sensibility and physical control of the tools.
Let’s start by looking at the usual tools of a painter: a set of brushes, a palette with colors, liquid to dilute and clean (water or turpentine), and a canvas. All of these tools, except for the liquid, are still indispensable in the digital world and they have been replaced by digital tools. But the question is: did they really achieve the aim of replacing the original ones and did they really get any better?
Starting with the brushes and taking for granted that a graphic artist usually works with a digital graphic tablet and a graphic pen, as I do myself, the question is if he is satisfied with the trade. To be able to get a work environment comparable with the analog world, is necessary to have a professional graphic tablet, with a pressure-sensitivity with 1,000 levels, and of course a graphic pen of the same level of quality. On the contrary, the strokes won’t have the sensibility and nuances that one would expect from a regular pen.
But even working with such quality tools there are some gaps to be filled. When an artist draws on paper with a regular pen there are numerous factors that will alter the resulting stroke. For instance, how sharp the pen is, the hardness of the pen, and especially the angle and position of the pen while drawing. It is true that some of these characteristics can be reproduced with the modern digital technology, but not in real time and in a fluid manner. Just one simple of stroke with a pen that takes one second can contain numerous nuances in the intensity and angle of the line. It is possible to achieve these nuances with modern applications, by using certain brush presets. But the limitation in the immediate response of the tool is still considerable, even when the most advanced models of digital tablets and pens have tilt sensitivity. This is probably the reason why many illustrators still prefer to start our sketches in paper and later scan them to be converted to vector drawing. I would like to make a comparison with the world of music technology, which I am quite familiar with.
The same thing happened when the first digital instruments showed up. Especially in the world of synthesizers because an important part of the expression and capability of controlling the instruments in real time was lost with the coming of digital synthesis. To be able to change a sound or certain parameters and nuances, the musician was obligated to go through a slow process of skipping numeric banks by hitting the same button. Before, with the analog instruments, it was as easy as moving a knob. Fortunately, in the 90’s the first virtual analog synthesizers were commercialized, offering the same result but offering the advantages of the digital world (saving information, stability, etc). This way, the capacity of acting in real time by using simple knobs was recovered. The difference between changing a sound in real time with a simple and progressive movement of a knob and to be able to listen to it’s effect at the same time, and changing a sound by hitting the same button 40 times to be able to listen to it is just enormous.
The same thing happens with digital graphic pens. Is not quite the same to be able to change the angle and texture of a stroke in real time, than drawing a stroke and later edit it with different brushes. It’s a big loss in expression and in the simple joy of drawing. Our work becomes poorer.
This happens also with other tools, such as brushes. You can’t compare the experience and result of using a hair brush with a digital pen with a brush preset selected. The touch and feel of moving a brush and distribute the color in the canvas is not comparable to a digital pen. On the contrary, all these centuries of learning about the use of the brush by the best painters in our history would be worthless. It is true though that in the last years Wacom has developed some nice tools as an answer to this problem, and I would like to remark the 6D Art Pen, the Airbrush and the Ink Pen. The Ink Pen is similar in construction to the classic pen but with the significant feature that this pen has the ability to write or draw with ink on paper and translate the information straight on to digital. It would be interesting that Wacom would think of a similar pen featuring the original drawing ink pen’s point, so the artists can use the expression of the different positions of the pen. I’m sure that, like me, many artists are waiting for the day that we can use digital brushes that can be used in the same manner as the digital pens.
Another big limitation from digital technology is the application of colors. For instance, an analog artist can put in one brush several colors and apply them on the canvas with control, and also mix them with just one stroke. The result of this action means richness and expression in the work. On top of it, the result can change depending on the consistency of the painting and the position. In the digital world, this is far from reality. Some applications such as Corel Painter, give you the possibility of painting strokes and fills in gradients, but it’s not quite the same.
Other programs like ArtRage let you paint in brushes that imitate the oil painting stroke and other artistic tools, but it’s not really customizable. I wonder when are we going to be able to have a tool that allows us to use different colors in the same brush and apply them in a realistic way. If you know any please give me some clue. It is true that is possible to create your own brushes and feature different colors and shapes into it, with a lot of work. But this is the same case as the synthesizers, working so hard on just one brush kills the creative flow of the artist. If for each stroke he wanted to take he have had to spend some five minutes programming a new brush, then Van Gogh would have turned into a boring programmer, instead of being one of the masters of Impressionist painting.
The problem in digital technology today is that we can get amazing results, but the creative flow is lost by trading it with investigation and custom made programming. As I said before, it turns the artists into laboratory scientist, and as a result the artist trades creativity and intuition by the mere use of effective techniques and tricks in which he has previously invested a long time.
Finally, I would like to refer to the last one of the painter’s tools: the canvas. It looks like science fiction but computers made us take a step back in psychomotor coordination by making us draw in one place while looking at another. And this is just in case you work with a tablet, because I know good designers who still draw with the mouse. I think this is a regression in painting techniques, and it is completely unnecessary. The only reason why we have all been accustomed to it is because there were no other choices. Fortunately, Wacom worked on it and offer a digital canvas called Cintiq, on which the artist can work directly. It calls my attention that Wacom decided to launch this canvas as a vertical model. I think that most of the designers and illustrators, at least from the old school, are used to drawing on draftsman slopping boards, which allow you to keep a good hand position for freehand drawing. I would suggest to Wacom to think about the possibility of launching an horizontal board canvas that lets the artist place the computer monitor in front in order to save space. Personally I think that the future of the art technology is about this, and I hope that in a few years a digital canvas is developed that, in the manner of a portable projection screen, lets the artist expand it in different sizes and paint on it without the use of the monitor. These kind of tools are possible today, but I imagine that they are not developed due to a lack of demand in the market, which is most oriented to vector design rather than art. Possibly, these tools come alive only when big animation studios such as Pixar need to use them.
Anyway, for those artists who miss the traditional analog way, I suggest them to keep painting in the old way if they can. And if they need to work digitally, my advice is to invest time in creating your own color palettes, and your own tools (Brushes, pens, pencils, etc). And the most important: don’t be afraid of experimentation. At the end of the day, this is a real advantage from the digital world: experimentation doesn’t mean any more that you may have to throw all that expensive material to the trash.
