Hello everyone, i am new at photographing musical instruments such as a saxophone. The lacquer on the instrument makes it extremely difficult to take the picture without a glare. I notice that professional photos of saxophones (like the manufacturer yamaha) uses all have in common this black line that goes through the instrument where the glare would usually be. does anyone know if there is a photo technique that is used while taking the picture that causes this black line to appear throughout the instrument? Any suggestions and or comments would be greately appretiated. thank you!
