Image: Comparison of Healthy and Problem Raspberry Leaves

This high-resolution landscape photograph presents a clear, scientific-style comparison of healthy and problem raspberry leaves laid out neatly on a smooth, medium-toned wooden surface. The composition is simple and balanced, emphasizing both clarity and contrast. On the left side of the image, two healthy raspberry leaves are positioned side by side. They exhibit a rich, uniform green color with a smooth matte finish. The veins are clearly visible, forming a symmetrical network typical of Rubus idaeus (raspberry) foliage. The leaves have well-defined serrated edges, intact margins, and a fresh, slightly raised texture. Their petioles (stems) are firm and straight, and the overall impression is one of vitality and optimal growth. The lighting enhances the leaves’ three-dimensional structure, with gentle shadows accentuating their natural contours without overwhelming the image.

On the right side, two 'problem leaves' provide a striking contrast. These leaves are similar in size and shape to the healthy ones but display clear signs of stress or disease. The coloration has shifted from deep green to a patchy combination of yellow, pale green, and brown, with irregular spots scattered across the surface. The discoloration patterns suggest possible nutrient deficiency (such as magnesium or nitrogen), early fungal infection, or environmental stress like overexposure to sunlight or drought. The leaf edges show curling and slight crisping, and the veins appear less pronounced due to chlorosis (yellowing of tissue around the veins). Some areas near the tips and margins exhibit necrotic browning, where the leaf tissue has dried out or decayed.

Above the leaves, clear black text labels identify the groups: 'HEALTHY LEAVES' on the left and 'PROBLEM LEAVES' on the right. The typography is bold, sans-serif, and evenly spaced, ensuring immediate comprehension. The labels provide a visual guide for side-by-side comparison, making this image ideal for educational use in agriculture, horticulture, or plant pathology contexts.

The overall tone of the photograph is warm and natural. The wooden background adds subtle texture and color harmony, complementing the organic subject matter without distracting from it. The lighting is even and soft, likely diffused daylight or studio lighting designed to minimize glare. The image’s composition and clarity suggest it was intended for documentation or instructional material, highlighting the distinct visual symptoms that differentiate healthy plant tissue from affected leaves.

This photograph could be used in scientific publications, gardening guides, pest management tutorials, or agricultural extension resources. It captures both the aesthetic and diagnostic aspects of plant health observation, serving as an informative visual reference for identifying early signs of leaf stress or disease in raspberry plants.
