E is for Exposure – #AtoZChallenge – 2020

E is for Exposure

Exposure is a general sense for how much light that reaches photographic film (or an image sensor, in the case of digital cameras). How much light that reaches the film is affected by:

  • shutter speed
  • aperture size
  • amount of light illuminating the subject

Faster shutter speeds reduce the amount of light hitting the film. Larger apertures result in much more light reaching the film. Low light scenes do not put much light onto the film.

A photographer must balance these three variables with the sensitivity of the film to optimize the amount of light getting into the camera in order to get the ‘perfect’ picture. Many modern cameras (including those on cell phones) automatically adjust each of these.

D is for Depth of Field – #AtoZChallenge – 2020

D is for Depth of Field

Depth of field describes the distance in front of and behind an object that is in focus at the same time that the main object is in focus.

We are, in general, familiar with this. If something is close to us and we focus on it, things in the background will be out of focus. Or, when we focus on something in the distance, things in the foreground become blurry.

Depth of field is slightly more specific in that it actually quantifies the space in front or behind an object that will be in focus. The construction of the lens has a strong effect on this. However, depth of focus can also be affected by the size of the aperture. As an aperture gets smaller, the depth of focus increases.

Depth of field can be used to create interesting photographic effects. It’s also important to control depth of field when photographing objects for professional publication or study.

C is for Camera Obscura – #AtoZChallenge – 2020

C is for Camera Obscura

The words “camera obscura” are derived from the Latin meaning “dark chamber.” In general, a camera obscura refers to an image formed as light passes through a tiny opening, like a pinhole.

Many original camerae obscurae were simply a darkened room with a small hole in a wall separating the darkened room from a well-lit space. People would gather inside for entertainment to watch took place in the illuminated space.

Today, pinhole cameras are a more common camera obscura that people may play with. People may also take advantage of pinholes to project images when solar eclipses occur.

B is for Bellows – #AtoZChallenge – 2020

B is for Bellows

Many older cameras possess bellows, an expandable dark chamber connecting the lens of the camera body to the camera body where the film is.

Polaroid Land Camera – The 800. 1957-1962

By being expandable, the position of the lens relative to the film can be changed to focus the image.

The Brownie Automatic. Also called the No. 2A Folding Pocket Brownie, Model A. A folding camera manufactured from 1910 to 1915.

More practically, being able to move the lens means that a camera can be folded up to a smaller size, therefore making it more convenient to carry.

Jiffy Kodak six-20. 1933-1937

A is for Aperture – #AtoZChallenge – 2020

A is for Aperture

The aperture is the opening in a camera through which light passes to get to the film. It is adjustable much as our own pupil expands or contracts with changing light conditions.

In photography, the size of the aperture not only affects the amount of light that gets into the camera (and onto the film) but also characteristics of the focus of the object being photographed.

A smaller aperture allows less light in. However, the resultant image is more likely to be in sharp focus. Larger apertures result in reduced focus, as anyone who’s had their eyes dilated will tell you!

With April comes the annual Blogging from A to Z Challenge. This year, Animal’s Place Creative Studios joins the fray with a series of blog posts related to cameras and photography.

The A to Z Challenge is to write a blog post every day in April (except Sunday) with a letter of the alphabet as a prompt.

Here are the letters for Animal’s Place. Links will be provided as the month progresses.

  • A is for Aperture
  • B is for Bellows
  • C is for Camera Obscura
  • D is for Depth of Field
  • E is for Exposure
  • F is for f-stop
  • G is for Grain
  • H is for Hotshoe
  • I is for ISO
  • J is for Joule
  • K is for Kelvin
  • L is for Lens
  • M is for Macro
  • N is for Negative
  • O is for Opacity
  • P is for Pentaprism
  • Q is for Quantum
  • R is for Rangefinder
