Visualize a close-up product shot of a toilet cleaner bottle, maintaining the iconic shape of the Harpic bottle but featuring the new brand name "Majumder" in the same typography. The image should be hyper-realistic, captured in 8K ultra detail, with a primary focus on the bottle's label and design elements. The background should consist of a soft gradient or light-colored surface that complements the bottle's deep navy blue and vibrant red label. Utilize a macro lens to achieve a sharp focus on the label, employing a wide aperture of f/2.8 to create a shallow depth of field, ensuring the bottle stands out sharply against a softly blurred background. The lighting should be soft and diffused, positioned to create gentle highlights that enhance the bottle's curves and textures, emphasizing the smooth, reflective surface. The label must clearly display "Majumder," with vibrant colors that evoke a sense of cleanliness and effectiveness. In post-production, include color grading to enhance vibrancy and apply a slight vignette to focus attention on the product. The final image should be a striking representation of the rebranded toilet cleaner, suitable for promotional materials.
