Macro Oil Paint Brush on Canvas

Create an ultra-realistic macro photograph of a single artist paintbrush applying thick oil paint onto a stretched canvas. The brush enters diagonally from the upper right toward the center, with a brush_handle_color wooden handle, a worn shiny silver metal ferrule, and natural bristles loaded with paint_color_palette paint. Show exactly one paintbrush and one canvas surface. The canvas is angled in perspective, filling the frame, with visible beige raw fabric along the lower right edge and heavy impasto paint across the rest of the surface. Emphasize raised ridges, palette-knife-like texture, bristle grooves, wet glossy highlights, and small scraped edges in the paint. Use dramatic realistic lighting from the upper left, creating a dark soft shadow under the brush and crisp specular reflections on the metal ferrule and wet paint. Background should be dark and out of focus, with shallow depth of field, high-detail texture, natural color grading, and a cinematic close-up composition in a aspect_ratio frame. No text, no hands, no extra tools, no watermark.
