In this part of this series, we will commence work with a simple landscape, a photo of the castle of Foix in southern France about the turn of the century. With the passage of time, this photo is now stated to fall within the public domain, has already been digitized by the Rosalis project of the municipal public library of Toulouse, and may be downloaded from Wikicommons at address: https:// | In this part of this series, we will commence work with a simple landscape, a photo of the castle of Foix in southern France about the turn of the century.

Once we have this file opened in Krita, the first thing I like to do is to rename and save it in Krita’s internal format. We will be using layers, which are not supported by the picture’s original JPEG format. By changing the format, we can ensure that layers are kept separate (and not fused together). We also make sure we are working on a new copy and not on the original file, which may be stored for further reference if needed — or if disaster strikes for whatever reason.** | Once we have this file opened in Krita, the first thing I like to do is to rename and save it in Krita’s internal format.

**Returning to layers, I then set up a new layer. It will, initially, be transparent. All modifications that imply adding color -- painting, spraying -- will be done to this layer, and not to the original image. If any serious errors are made, they can be wiped off on the new layer, without affecting the original. Giving each layer a (significant) name may be of help. Please note in the screen capture that the new layer is placed above the original, so that changes will be readily apparent. Also, note that any changes made will be to the layer that is currently active — the new layer in this capture. | **Returning to layers, I then set up a new layer. It will, initially, be transparent.

Let us begin with the picture borders. Most defects are to be seen around the top edge, and affect the sky. We can cover them with a paint color similar to the sky itself, making them disappear. Choose any brush you feel comfortable with; Krita has a large selection, comprising both pencils, felt-tips, and an airbrush. This latter is my personal choice, with a low opacity setting and relatively small size — both of these are configurable with horizontal bars set just beneath the top menu bar. ** | Let us begin with the picture borders.

**Begin by right-clicking on a suitable piece to sky to copy that color and make it your brush’s active color, and then proceed by applying small touches. Brushing ever more lightly and with many applications to build color is the ticket. In passing, the same technique may be used to wipe the sky of its ungainly black dots. The end result is not perfect, with its very uniform appearance, but it is still rather more pleasing than in its original state. | **Begin by right-clicking on a suitable piece to sky to copy that color and make it your brush’s active color, and then proceed by applying small touches.

As can be seen above, the extreme left of the image has a thin row of dark pixels running from top to bottom. Partly an artifact, and partly due to the original photographic process, this defect can be resolved in part by painting in details, thus reconstructing the scene by extending the visible part of the image left towards the edge.

We are left with a rather better edge all round, except for the dark spot in the extreme lower left corner, and the lighter blemish around it. | **All along the lower edge of the image, we find a similar dark strip that can also be cut out by cropping.

To clear up the light-colored blemish, a natural tendency would be to use some dark color on it. But it is clear that applying color directly would only create a dark mass, with all details lost beneath it. To avoid this mishap, we can create a third layer. This time, its mode of combination with the layers beneath it should not be “Normal”, | To clear up the light-colored blemish, a natural tendency would be to use some dark color on it.

**In this part of our series, we have set up our image in Krita, and used two new layers, one a covering layer to hide defects beneath new paint, and the second a darkening or overlay layer to darken the original details and set the overall density of a specific area back to an acceptable average. I encourage the reader to practice some or all of these techniques on this image, or any other of your preference, and we will be back in the next part to try solve the issue of the dark castle and trees to the right of the photo. Until then, take care!** | **In this part of our series, we have set up our image in Krita, and used two new layers, one a covering layer to hide defects beneath new paint, and the second a darkening or overlay layer to darken the original details and set the overall density of a specific area back to an acceptable average.
