... the lens from scratching and from accumulation of deposits and dirt. The UV filter also aides in sharpening the photograph under hazy conditions. Polarizing filters may be used in highly reflective conditions. If tungsten lighting is used, then a blue filter, such as an 80B, is commonly used to correct...

... surface without shadowing from the lens. When using a ring flash for macrophotography, the higher focal length macro/micro lenses have the disadvantage of having the flash at a higher angle of incidence for side lighting, which diminishes the side lighting effect. If side lighting is critical, a lower...

... at magnifications from 1 to 50 or 100×, it may be conducted by the unaided eye, a hand lens or magnifier, a low-power stereoscopic microscope, or a SEM. Macroscopic photography of up to 20× magnification requires a high-quality camera and special lenses; alternatively, a large magnifying glass may be used...

..., highly reflective surface indicates brittle cracking by cleavage or intergranular fracture. In addition, when intergranular fracture occurs in coarse-grained materials, individual equiaxed grains have a distinctive rock-candy appearance that may be visible with a hand lens. Surface roughness provides...
