Lit with a bare, clear glass projection lamp having a 1 centimetre filament. Lighting angle and all other technical factors were the same for both photos. Note how much better the small source has rendered the specimen. There's more to making good close-ups than getting close enough to the subject, stopping the lens down, and keeping the camera steady.
Lighting is also an important factor.
Avoid flash mounted on the camera. You can't observe the lighting effects until it's too late. The single frontal-light source obliterates much of the detailed texture of the subject. The best lighting results in photomacrography are accomplished by using very small light sources and patiently manipulating them to enhance the subject's form and details. The result of the lighting should be observed through the camera viewfinder before the picture is taken.
