A cinematic and photorealistic image captures an epic fantasy battle scene set in a vibrant yet desaturated forest. Amidst the sharp and clear lighting, a paladin stands in intricate, gleaming armor, holding a subtly radiant sword and shield. Next to him, a mysterious wizard in a hooded robe adorned with arcane symbols grasps a staff topped with a softly glowing orb, his face obscured by the hood. On the other side, a vigilant ranger, wearing a detailed leather cloak, grips a longbow, ready for action. They confront a colossal three-headed dragon, its richly textured scales in muted hues. The forest backdrop, with its natural, understated colors, highlights crisp details, while the tridimensional perspective draws viewers into this epic clash.
