7 : Overcast

In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator '9' indicating that the sky is totally obscured (i.e. hidden from view), usually due to dense fog or heavy snow.[1]
Pilots flying visually (VFR, see Learning Goal 1g) must stay outside of clouds.Even those flying in instruments (IFR)are concerned if there is a low overcast (i.e. a low ceiling) overtheir destination airport. For this reason, cloud coverage is importantto pilots.
Caution: If you are flying at an altitude just above or just belowthe clouds, then in your slant or oblique view, the sky will look muchmore overcast than it really is. The reason is that with an obliqueview, the vertical body of the cloud blocks your view of clear spaceshorizontally hidden behind the cloud. Most of the photos below looklike greater cloud coverage than they actually are.
Think of an overcast day as a huge soft-box that dims light down during every step you make. Encourage yourself to get outside when heavy clouds are graying your window. Almost any photograph, no matter the discipline you feel the most affinity for, can be enhanced with the rich soft light on overcast days.
