The tree in early spring (The Gaza field in Karlovac) en plein air
Alfred Freddy Krupa, 1995
what to study here
It shows a clear three-band value plan and a contrast between crisp branch drawing and loose, unblended field strokes in a small outdoor study.
Look at how this study is organized into three value bands. The tree trunk and branches are the darkest note, near black. The field sits in the middle as pale cream and yellow-ochre. The sky is brightest at the horizon and deepens to blue at the top. Squint and the tree reads as one dark shape against a light field. The vision guide describes the branches as crisp, tapering strokes that reach upward, with a pinkish warmth in the trunk. Compare that controlled drawing with the field, which is brushed loosely in horizontal strokes with no blending, so the marks stay visible. The blue water accents are quick broken strokes that suggest wetness and echo the sky without describing detail. The sky edges are soft between blue and white. Notice how little is resolved: the distant hills barely register at the horizon, and the field stays simple so attention goes to the tree. For a plein air study, this shows how to put hard edges in one place and loose handling everywhere else.
key decision
The painter kept the tree as the only dark, crisply edged form and handled the field and water loosely with visible horizontal strokes and broken blue accents. This puts the focus on the tree.
recreation guide
This recreation guide addresses Alfred Freddy Krupa’s 1995 work 'The tree in early spring (The Gaza field in Karlovac),' an oil-on-board study executed en plein air. As a contemporary realist sketch, the work prioritizes the immediate capture of light and atmospheric conditions over polished finish. The process relies heavily on traditional oil painting principles adapted for outdoor speed and accuracy, specifically the use of a monochrome underpainting (grisaille) to establish value structure before applying color glazes and scumbles. This method allows the artist to manage the complex interplay of light and shadow inherent in early spring landscapes without muddying the colors, a technique supported by historical treatises on oil painting practice.

preparation
surface prep
Prepare a rigid board surface. While specific preparation for Krupa is not detailed in the sources, traditional oil painting on board requires a stable, non-flexible support. The surface should be primed to accept oil paint. The sources emphasize that oil painting on wood panel has been common for centuries, offering advantages in flexibility and color density (Source 2). Ensure the surface is smooth enough for detailed study but textured enough to hold the brushwork of a plein air sketch.
underdrawing
Begin with a charcoal drawing. Do not hesitate to hold the brush or charcoal against the subject (the tree/field) to ascertain lengths and proportions. Make the study slightly smaller than life to facilitate comparison. Use a dry brush to model the charcoal shading. Crucially, place the drawing alongside the subject, on a level with the face (or main focal point), and use a hand-glass to compare the drawing with nature. This obviates doubts about scale that arise when the picture is nearer to the artist than the sitter (Source 1). Make all corrections in the charcoal stage, as charcoal offers little resistance to a brush and none to bread (eraser). It is reckless to put down paint with obvious errors in construction (Source 1).
underpainting
Execute a monochrome underpainting (grisaille) using raw umber and soft white, thinned with turpentine. This stage establishes the value structure of the scene. The goal is to mentally extract red and yellow colors, translating what would be left in nature if those colors were not present (Source 3). This monochrome layer must be allowed to dry completely before proceeding. This technique provides a stable foundation for subsequent color layers, preventing the muddiness that can occur when mixing colors directly on the palette for complex lighting conditions.

composition
The composition is a plein air study, likely focusing on the interplay of light and shadow on the tree and field. While specific compositional elements of this painting are not described in the sources, the artist’s practice of painting from life suggests an emphasis on capturing the immediate visual impression. The use of a hand-glass during the drawing phase ensures accurate spatial relationships (Source 1). The composition likely utilizes the principles of visual ordering, where elements like line, shape, and value relate to each other to create a cohesive whole (Source 7).
step by step
underdrawing→underpainting→first pass→refining→finishing
underdrawing
step 01
Draw the scene in charcoal, making it slightly smaller than life. Use a dry brush to model shading.
Tip — Place the drawing on a level with the subject and use a hand-glass to compare proportions.
Charcoal drawing
step 02
Correct all errors in the charcoal stage. Use bread to erase if necessary.
Tip — Do not proceed to paint if there are obvious errors in construction.
Correction
underpainting
step 03
Apply a monochrome wash using raw umber and soft white, thinned with turpentine.
Tip — Focus on value structure, mentally extracting red and yellow colors.
Grisaille
step 04
Allow the grisaille to dry completely.
Tip — Patience is key; wet layers will mix unpredictably with glazes.
Drying
first pass
step 05
Glaze and scumble with oil, introducing yellow and red tones.
Tip — Apply transparent coats of color (glazing) and semi-opaque layers (scumbling) to tint the monochrome base.
Glazing and Scumbling
refining
step 06
Use complementary colors to intensify or soften hues as needed.
Tip — Surround an orange tone with blue to make it appear more orange; soften a red with green tones.
Simultaneous Contrast
finishing
step 07
Review the painting for lucidity and correct any muddiness.
Tip — Avoid excessive correcting in paint, as it can be fatal to lucidity.
Final Adjustment
critical techniques
Glazing
Applying a transparent coat of color over a dry underpainting to modify hue and value without obscuring the underlying structure.
Scumbling
Applying a semi-opaque layer of paint through which the underlying painting makes itself felt, often used to create coldness or grey blooms over darker grounds.
Simultaneous Contrast
Using complementary colors in juxtaposition to enhance the intensity of each other, or using similar colors to soften a pronounced hue.
Monochrome Underpainting
Establishing the value structure of the painting in a single color (raw umber and white) before introducing full color, ensuring accurate light and shadow representation.
common pitfalls
- →Putting down paint with obvious errors in construction or drawing, which is reckless and leads to fatal correcting in paint (Source 1).
- →Mixing colors directly on the palette without considering the underlying monochrome structure, leading to muddy results.
- →Ignoring the effects of simultaneous contrast, resulting in colors that appear dull or inaccurate in relation to their surroundings (Source 4).
- →Attempting to complete the study in one sitting; the process requires multiple passes (at least three or four) to achieve depth and lucidity (Source 1).
what the sources don't tell us
Where the corpus is silent, we say so rather than guess. These are the gaps a complete recreation guide would normally cover that our source passages don't.
- ·Specific details of the tree and field in the painting are not described in the sources, so the guide relies on general plein air techniques.
- ·Alfred Freddy Krupa's specific palette preferences are not detailed in the sources, so the guide uses traditional pigments mentioned in the texts.
- ·The exact varnish or medium used by Krupa is not specified, so the guide suggests traditional oil and varnish mixtures.

what the eye sees
A bare tree with upright, reaching branches dominates the left foreground, rendered in dark brown with pinkish warmth in the trunk. Its silhouette anchors the composition against a sky that transitions from deep blue at top to pale cream-yellow at the horizon. Flat wetland stretches across the middle distance, pale and cool, threaded with blue water passages that echo the sky above. The eye lands first on the dark tree mass, then travels horizontally across the open field toward distant hills barely visible at the horizon line.
value structure
The painting rests on a clear three-band value structure: darkest at the tree trunk and branches (near black), mid-light across the field (cream and pale yellow-ochre), and bright at the sky (deep blue fading to near-white at the horizon). Within the field, blue water accents create visual punctuation. Squint and you see the tree as one dark shape against the bright field, with the sky as the brightest plane overall.

edges and brushwork
Branches are painted with controlled, crisp edges—clean strokes that taper as they reach upward. The sky features soft, blended edges between blue and white cloud forms, suggesting atmospheric depth. The field is rendered loosely with horizontal directional strokes left deliberately visible; no blending smooths the cream and yellow together. Water accents are placed with broken color—quick blue strokes that don't describe detail but suggest wetness and reflection.
a working sequence
- 01
Establish composition and horizons
Lightly block in the tree's position on the left side, the horizon line roughly in the lower third, and the field's horizontal extent. Indicate the tree trunk as a single dark mass first—don't worry about branches yet. Mark where water passages will break the field.
- 02
Paint the sky broadly
Block in deep ultramarine blue across the upper portion, leaving cream-white at the horizon line. Use loose horizontal strokes to suggest clouds—don't blend them smooth. The blue should be deeper and richer at top, graying and warming toward the horizon where light breaks through.
- 03
Lay down the field foundation
Cover the middle ground with pale yellow-ochre and cream, keeping strokes horizontal and loose. Don't aim for smoothness; let brush marks show the landscape's flatness. Leave some white canvas peeking through in the foreground—this underpainting is part of the effect.
- 04
Paint the water passages
Use ultramarine and soft blue-green to suggest wetland and reflected sky. Keep these strokes broken and directional, following contours of the ground. Don't outline them—let them sit as color shapes among the field's cream tones.
- 05
Define the tree trunk and primary branches
Mix a dark—ultramarine + burnt umber, nearly black—and paint the main trunk as a strong vertical form. While still wet or on top, add the three to four primary limbs reaching upward and outward at slightly different angles. Keep edges clean and controlled.
- 06
Add secondary and tertiary branches
Continue subdividing branches as they rise, using slightly lighter mixes of dark brown as you move away from the main trunk. Some branches taper to delicate lines. Vary the branch angles so they don't look mechanical—they should feel like a living tree reaching toward light.
- 07
Warm the tree's lower reaches and shadows
Touch burnt sienna or dark red-brown into the base of the trunk and lower branches to suggest spring warmth and shadow. These warmer undertones make the tree feel rooted in the pale field rather than floating on it.
- 08
Final details and atmospheric touches
Add any small distant darks or details on the horizon. Consider adding a few dark brushstrokes in the foreground field to suggest vegetation or shadows. Step back—the painting should feel fresh and unfinished, like a plein air study, not labored.
where studies of this painting go wrong
- Overworking the tree branches until they look stiff or too uniform in weight; vary the character and let some taper convincingly
- Blending the sky into smooth gradations, which kills the freshness; keep cloud edges soft but not fused
- Making the field too detailed or busy; it should recede and stay simple to focus attention on the tree
- Losing the integrity of the water passages by trying to describe them; treat them as color accents, not landscape features

- beginner friendliness
- value contrast
