What does OBL mean in MEDICAL

Oblique lighting is a photography technique in which one or more light sources are used to cast shadows in order to bring out texture, depth, and form in an image.

Oblique lighting helps create dimensionality by adding contrast and shading among objects within the frame of the photograph. The use of this method also allows for better separation between foreground and background elements, creating a sense of depth.

You can incorporate oblique lighting into your photos by positioning one or more light sources at angles relative to the subject being photographed. Try experimenting with different angles and distances for each light source until you get the desired effect.

The most important pieces of equipment when using oblique lighting are lights and diffusers. Appropriate types of lights include strobes, LEDs, tungsten bulbs, etc., while diffusers can be made from fabric materials like muslin or translucent plastic such as Plexiglas or acrylic sheets. A tripod is also highly recommended when capturing images with oblique lighting techniques so that the camera doesn't move during captures.

When doing makeup with oblique light it's important to pay attention to how light reflects on skin tones. You will want to consider factors such as color intensity and finishes when choosing your makeup products so that they look natural when illuminated from these angled light sources. Additionally you may want to apply blush or bronzer along with additional highlights for added effect.
