This is contrary to standard practice in the printing world, where darker inks are always applied on top of lighter, and black is naturally the last to go on.

Now, it was “merely” a question of slowly working in the color in the lower layer. Several aspects came to light. In the first place, it is clear that, in real color photos, there tend to be very few large areas of uniform color. Even in this image, with its rather flat sky due to over-exposure in the original, we can give some life by putting in some slight gradient, especially in the parts that are at a distance.** | Now, it was “merely” a question of slowly working in the color in the lower layer.

**As can also be seen from this detail, both the rock surfaces to the right and the terraced fields to the left are composed of various colors: dark green trees and shrubs clinging to the rocks, the rock surfaces themselves as a light, creamy, limestone, and other types of vegetation such as grass or cereals in the fields. Careful use of the airbrush with a choice of several (2 to 4) colors for each type of terrain may be of help here. | **As can also be seen from this detail, both the rock surfaces to the right and the terraced fields to the left are composed of various colors: dark green trees and shrubs clinging to the rocks, the rock surfaces themselves as a light, creamy, limestone, and other types of vegetation such as grass or cereals in the fields.

Even wide expanses of mixed vegetation near the tops of low mountains in the background will need some grading. To the right side of the complete image, I used several shades of green in wade bands. Actually, these were laid down using a completely opaque crayon, and not the airbrush. To blend horizontal bands in together, I then used one of Krita’s “wet knives” to move the color, to blend and mix as if it were wet oil paint.** | Even wide expanses of mixed vegetation near the tops of low mountains in the background will need some grading.

+ | Comme nous pouvons le voir aussi dans ce détail, les surfaces rocheuses de droite comme les champs en terrasse de gauche sont composés de couleurs variées : le vert sombre pour les arbres et les broussailles escaladant les rochers, le calcaire clair et soyeux des rochers eux-mêmes, et d' | ||

**In this same detail, we can note that the presence of the trees in the foreground make coloring the mountainside rather more difficult. Instead of drying the background around the branches -- which would be quite impossible due to the sheer amount of wood in the foreground -- I painted the lot over in the colors of the mountainside grass. Then, a clearer shade of wood color was used, with a fine airbrush, to change the tone of the trees. Some bleeding has occurred in places, but the end result is rather life-like. | **In this same detail, we can note that the presence of the trees in the foreground make coloring the mountainside rather more difficult.

Our choice of colors for vegetation and natural formations is rather limited: grass will, in general, be green, tree limbs will have a wood color, and rocks will each have their own colors within a limited range of possibilities. Choosing colors for these parts of the image is, thus, rather easy. If in doubt, using a modern photo taken of the same place may put us on the right track and, even, allow us to open both images in Krita and choose colors directly from the recent image and transfer them directly to work on the black and white photo we are coloring. However, things are more complicated when man-made objects may be more complex.** | Our choice of colors for vegetation and natural formations is rather limited: grass will, in general, be green, tree limbs will have a wood color, and rocks will each have their own colors within a limited range of possibilities.

**The roofs in this image are quite clearly ceramic tiles, which at that time must have been some shade of terracotta, from brick-red to pink or even yellow ocher. However, nobody alive could tell us which colors the shutters of the houses were. A certain variety of shutter paint colors is to be expected; however, assignation must to some extent be a subjective choice. I simply did try to follow usual practice, and assign similar colors to each shutter of the same building, and different colors to neighboring houses. In the same way, the lettering of the hotel name on its gable in the background must have stood out from the background. But, was it red, green or blue? That could be anyone’s guess. | **The roofs in this image are quite clearly ceramic tiles, which at that time must have been some shade of terracotta, from brick-red to pink or even yellow ocher.

In the next part of this series, we will change subjects. We’ll work on an early 20th century image, a studio portrait. Paul Trappen, presented as the world’s Strongest Man, was photographed and the resulting prints sold as a postcard. The result is now available on Wikimedia Commons at address https:// | In the next part of this series, we will change subjects. We’ll work on an early 20th century image, a studio portrait.
