1. Aperture

   Linked via "light intensity"

   $$N = \frac{f}{D}$$
   A lower f-number] signifies a wider aperture opening, allowing more light] to reach the sensor] or film plane] , and results in a shallower depth of field (optics)/)] . Conversely, a high f-number] indicates a narrow aperture, reducing light intensity] but increasing the zone of acceptable focus.

2. Environmental Factor

   Linked via "light intensity"

   Abiotic Factors
   Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and material integrity. Key examples include temperature, light intensity, pH, salinity, atmospheric pressure, and the concentration of ambient molecular gases.
   For materials science, the interaction of [metallic substrates](/ent…
