Camera Troubles – Part 3

The Correlation Of Physical Human Vision And Photography Camera truly makes a lot of sense when the purpose of each part is clearly explained!

As we have studied in the last two blog posts (Camera Troubles & Camera Troubles – Part 2) the camera Lens is comparable to our Cornea, Iris and Pupil. The Lens glass is designed to focus and adjust for telephoto. The camera Lens is comprised of at-least two pieces of glass (I say “at-least” because there are “Prime Focal Lenses” and “Variable Distance Lenses” which we call “Zoom lenses”.), the first being the lens we can see and should refrain from touching; the second being capable of moving microscopic distances for the purpose of focusing.

Perhaps this is a bit more theory than anyone would choose to know. Although I would not be writing this series of posts if I did not believe this information would benefit you as you daily take joy in photographing your life and the wonderful moments with your loved ones.

In side the camera Lens is the Diaphragm adjusted in stops which we photographers call “f/stop” or “Aperture”. The solid and flat construction of the Diaphragm is a little hard to explain, but let me tell you about its purpose; it is designed to adjust the opening in small amounts to regulate the saturation of light to reach the Sensor. This is the same purpose that our Iris serves by regulating the size of our Pupil and allowing just the right amount of light to pass onto our Retina.

The camera’s Sensor is a sensitive piece of equipment because it is made to be able to see things in relatively low lit situations. In fact I would say that the Sensor is the most delicate pieces of a camera when subjected to light. If anyone remembers the days of film photography, the Sensor in our digital cameras are the modern replacement of film. Do you remember looking for the right “film speed” and handling one film set after another? Oh the questions I had; and the answers I received were such an education! The camera Sensor and its inspiration our Retina (even the original film) are designed to be sensitive to light, leaving temporary impressions to be received into our memory.

There is a notable difference between our Eye and a camera’s Sensor system. The difference is this, Our Eye sees things in continuous motion and high rates of speed (something along the lines of video), whereas the camera is designed to see things as individual momentary pieces of halted time.

This is a lot of fun to discover new things about our camera! There is more to discover about the camera and some specifics as to how we can get the best out of them. Stay focused; we will capture some more details later this week!

For the Thanksgiving press: “Aperture or f/stop?”

A quick word from our photographer at Foe-toss -LIGHT before we begin snapping photos of the next family gathering for the Thanksgiving holiday!

“As I take indoor shots of a room or the people in it, I have to be very careful to monitor my camera’s shutter speed. If I let the shutter slow 1/15 to 1/30 of a second I will find my photos becoming blurry. Here are a few ways that you can effectively change you shutter speed without going into a full manual mode.

Use the “AV” preset camera setting. “AV” stands for “Aperture Value” and as you use this preset it will adjust the other settings to properly expose the scene your camera receives. Let me explain what “Aperture” means: Aperture refers to the diameter of the opening of the diaphragm in the lens. This diaphragm is designed to open and close at precise increments to allow a specific amount of light through the sensor (which used to be film).

Each increment of aperture larger or smaller is described as an “f/stop”. Each “f/stop” will be shown in this format, “f/13 .”

* Note that the smaller the f/stop number (i.e. f/2) the larger the opening in the lens diaphragm and thus allowing more light into the camera. Likewise the larger the number (f/18) the smaller the diaphragm opening and lesser amounts of light entering the camera. *

The f/stop adjusts your depth of field, so be aware, that if you begin shooting with a smaller f/stop, be sure that your focal point is in focus. The smaller the f/stop means the more accurate you camera must be set for the focal object’s distance.

Light is the key to all good photographs!

Once you have the f/stop set at an acceptable place your shutter speed should change by measuring at what speed it needs to operate. (It may only change when you press the shutter button half way down to focus!)”

Thank you for reading and have a blessed Thanksgiving!

“Thank you Lord God for family to share the joys of life with and to comfort us in times of difficulty and trial. Thank you for friends who are willing to encourage us and be the friends we need! Thank you for a Savior who is family, friend and more than these to us that we may be adopted children to You and siblings to Him, Jesus the anointed lamb of God!”
