A cinematic and photorealistic image captures an epic fantasy battle scene set in a vibrant yet slightly muted forest. The focus is on a paladin dressed in intricately detailed armor, wielding a subtly glowing sword and shield. Beside him stands a mysterious wizard shrouded in a hooded robe, adorned with complex arcane symbols that weave across the fabric, holding a staff topped with a gently luminescent orb. The wizard's face remains hidden by the shadows of the hood. To their other side, a ranger is seen wearing a finely crafted leather cloak, skillfully poised with a longbow. They confront a formidable three-headed dragon, its scales textured richly yet with subdued colors. The forest's lighting is sharp and pristine, emphasizing the crisp details of both characters and surroundings, while maintaining natural, understated hues.
