Tidbits of the digital Chicago method Part 6 - Initiating selections and transformations in ProcreateWritten by Krisztián Vértes
Being able to do quick editing at the wall can be rewarding at times. We’d like to show you how to make precise selections and interact with the selected elements in Procreate.
Due to centuries of decay and abuse of the monuments, there is one apparent feature that stands out immediately when we look at tomb or temple walls today: the tremendous amount of loss of the original surface.
When we look at ancient Egyptian monuments, color is to be found everywhere. Documenting either tombs, temples or the smallest painted graffito, we must provide a reasonable solution for recording the painted remains of the surface.
Let’s talk about… Ears – stylistic attributes and visual representation guidelines based on carved and painted examplesWritten by Krisztián Vértes
In this new series of tutorials, digitalEPIGRAPHY would like to draw your attention to the importance of stylistic accuracy in epigraphic documentation by focusing on the representation of a common feature, the human ear.
One of the most understated requirements of digital inking is the ability to be in full control of line placement and line quality. Obviously, ink line quality can be altered by several aspects as is often dictated by the publisher’s requirements.

Using your studio computer in the field Part 2 – Providing remote access to shortcuts while drawing on the iPadWritten by Krisztián Vértes
In the second part of my introduction regarding using full-fledged desktop software in the field, I’d like to elaborate on the importance of creating the best possible workflow for our documentation needs.
Just a few years ago it wouldn’t have occurred to me to take my precious laptop to the temple, however in the last couple of years I grew accustomed to having the benefits of accessing desktop applications when working on certain field projects.
When inking large drawings with multiple layers, one can easily get lost in the details. This focus-oriented process often leads us to craft repetitive tasks manually, over and over, until our hands hurt.
Upon upgrading from Photoshop CC 2017 to CC 2018 there are a few differences to be noted regarding to the using of the standard brush tool. There are changes to the brush presets panel, allowing users to manage brush presets more quickly and easily...
As it was already explained in the first edition of the Digital Epigraphy manual, Photoshop is our choice of quintessential tool when it comes to digital inking in the studio. We paint most of our brush strokes freehand using very little artificial help.
There are two slightly different methods that can be introduced here: the artist can either delete from or add to the initial curves. They are both very effective and, once mastered, they can be useful complements to hand-drawn brush strokes.
Restored decorative elements and architectural features, when part of an inked drawing, are represented by a series of dashed lines, as we’ve discussed in Chapter 2, Section 3. Again, just as with dotted lines, drawing dashed lines digitally can be accomplished in more than one way.
Modeling is indicated by a stippled area in which the variety in dot density adds a certain dimension to the texture. As with dotted paint lines and dashed architectural lines, the artist is free to add all the dots individually, and this is probably the easiest way to do so, especially when the area to be modeled is fairly small.
There are two slightly diﬀerent methods that can be introduced here: the artist can either delete from or add to the initial curves. They are both very eﬀective and, once mastered, they can be useful complements to hand-drawn brush strokes.
Using the Pen tool is the most precise and most controllable way of drawing curved paths for brush strokes. Its main advantage over the Freeform Pen tool is that the artist determines the number and position of the Anchor Points he/ she wants to use along the path.
Changing the arc of a curved line is just as hard in Photoshop as it is on paper - assuming the artist is drawing freehand. The artist has to pay attention to keeping the smoothness, the thickness, and the sun-shadow transitions of the original line while carefully adding and removing extra brush strokes.
Astropad, like all Apps that create a bridge between computer and iPad, has a desktop version that provides the necessary connection. Upon initial opening of the Mac App, one has to decide what percentage of the computer screen should be allowed to appear on the iPad.
The best way to make local enhancements over smaller areas is by using the Burn and Dodge tools. The Burn tool can be used over light areas to make the pencil lines appear darker. When the artist uses the Burn tool, he/she has to be very careful
There should be some customization performed on the tablet’s button interface before putting it to work. When we click on the Functions tool, we see a picture of the left/right string of buttons with some commands already associated with them. These buttons are called Express Keys and can perform tasks associated with certain mouse clicks.
Layer Masks are one of those Photoshop features that beginners might find hard to work with, although the philosophy behind masks is very simple: masks enable the artist to hide or reveal parts of a layer.
As a final preparatory step to ready the digitally penciled drawing for studio work, the artist needs to readjust the scale of the drawing to match its original dimensions. Since downscaling was a temporary necessity, required only to match the iPad’s and Procreate’s current limitations, we need to upscale our layered psd file to the same pixel resolution as it first appeared on our Template.
The artist needs to execute a few modiﬁcations to be able to work with a color version of his/her drawing. The drawing is created in a grayscale environment, so any color that would be applied on it would show as a shade of gray.
The Magnetic Pen Tool is an option of the Freeform Pen tool that lets the artist draw a path that snaps to the edges of deﬁned areas on the drawing. We can set up the range and sensitivity of its behavior as well as the complexity of our path
Before the artist starts adding the collation sheets to the digital drawing, he/she needs to set up the current stage as a layer for future reference. Later on, when we need a before and after collation comparison, this layer will be the one to which all subsequent changes can be related.
Once the jpeg is imported and placed in the relevant project’s folder, we can move on to Procreate’s interface customization. There is not a lot to do here, but one should be aware of a few tweaks that could potentially help with work in the field.
Procreate lets the artist paint in high resolution using customized brushes in a multilayered environment. It has a simple user interface, with most of the settings and options tucked away in hidden menus, keeping the canvas uncluttered. On initial opening of the App, the user is presented with a series of sample artwork made in Procreate
Although the digital inking method that was specifically developed for documenting the remains of some late Roman murals will be explained in another chapter, the multiple ways in which data is initially captured at Luxor Temple justify a brief introduction here.
