There is this coffee business in at the office.  We are about 500 individuals in this building.  The lady-barista told me they use three pounds of coffee daily and four on busy days.  How much coffee co-workers consume at this vendor?

If one pound = 460 g and 1 cup of coffee requires 10g, therefore they sell between 130 to 180 8-ounce cups of coffee on a daily basis.  That’s equivalent of 523 homo sapiens collectively consuming 1.25 cups of coffee on a weekly basis.

We are not taking into account the coffee that is consumed away from this coffee idle, i.e. french press enthusiasts [like myself and other colleagues] as well as the coffee that the company offers at the braking rooms and other DIY individuals.

This is very, very low if you compare that the global weekly consumption is ~6 cups a week.  According to the same source the weekly consumption on Guatemala is 2.5.

Trinitarian thoughts on the volcanos Agua, Fuego, Acatenango:

How does it look when it is photographed with frontlight as opposed to soft diffused light? Or does it look best with sidelight? This is a project you can keep doing throughout the year to see how the light changes over seasons.

The point is to understand how the light affects your subject.

To continually improve your photography, become a student of light. Even when you do not have your camera, be aware of the type of light in your surroundings and how the light changes. Take notice when sun changes to shade or, even better, when shade turns to sun.

Seens that not only wind is a friend of spec but also light.

With this criteria I could also begin a light analysis of the pictures included in this post of Pics for Presentations; all of them performed by me.

Aperture

The aperture also determines how many of the incoming rays are actually admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time). In the human eye, the pupil is the aperture.
