Capturing Memories at Neptune Memorial Reef: Photography Tips

Equipment Preparation

• Camera Selection: Use a waterproof camera or housing that suits your diving needs. DSLRs and mirrorless cameras with underwater housings are ideal for high-quality images.
• Lenses: A wide-angle lens is recommended for capturing the expansive underwater architecture and marine life, while a macro lens can help you focus on smaller details like coral and invertebrates.
