I'm Still Out Sick, Here's a Quick Reading Supplement to Your Film Today

AP - Please check Canvas to see what your grade is for your "One Idea" assignment.  Also check the Comments for this assignment to see if Punkt was added, or not.  We'll be discussing and sharing these photos with one another next week when Digi Photo 1 & 2 are out shooting.

Please follow along with the other two classes the reading assignment posted below, to refresh your memory on how the Manual Functions on the DSLR camera work.

You'll be staying in today to watch this documentary with the other two classes.

Today you'll be watching the Netflix film, "Night on Earth", using state-of-the-art digital camera technology that turns night, into day, through the lens of the camera. There are many ways this technology works, but one of the ways is directly related to a not-so-distant-future lesson plans that we'll be diving into later this semester, that relate to the Manual Exposure Functions on the DSLR cameras you'll be using in class.  Consider the information below as a primer to those lesson plans.
Read this information below, and then click on the link at the very bottom to read a short article that relates to one of the main technologies used in today's film.

(NOTE: The footage in this documentary that looks like a negative image, is a different thermal technology, that doesn't relate to these manual functions below.  The footage that looks like it was take during the day, uses advanced ISO technology, which DOES relate to the manual functions you'll be learning about in this class.)

There are 3 ways that a DSLR camera captures light when you hold the shutter button down to take a photograph.  To control the look of a photograph, these 3 manual functions are Aperture, Shutter Speed, and Film Speed (ISO). All images capture on a DSLR are capture on the CMOS sensor.  This is the digital version of analog film.

1.       Aperture – Like the iris of our eyes, the Aperture is a round opening that expands and contracts to control the AMOUNT OF LIGHT that enters the camera. The Aperture is housed in the lens.

2.       Shutter Speed – Setting the speed of the shutter determines the TIME THAT THE LIGHT is exposed to the CMOS sensor, where the image is capture in the DSLR Camera.

3.       Film Speed (ISO) – This determines how quickly the LIGHT IS ABSOREBED in the sensitivity of the CMOS sensor on the camera.  When you are in low light situations and your Aperture is opened as far as it can be, and can’t let in anymore light, setting the ISO to a higher (faster) number will allow you to properly expose your image.  The trade off is that the higher (faster) the ISO, the quicker light is absorbed, and this sacrifices the quality of the image.  ISO of 100-800 (slower) will give you a crisper, higher quality image. ISO of 1600 -12,800 will give you a grainy image.

Here's a useful chart for all of you visual learners out there:

Please read this short article that further explains more about how ISO works.  These digital film cameras in the documentary you'll watch today, use ISO the same way that digital photography cameras use them.  We'll discuss this further when I'm back from being sick.
