Measure Sunglasses Size

measure sunglasses size
  • (sunglass) a convex lens that focuses the rays of the sun; used to start a fire
  • Sunglasses or sun glasses are a form of protective eyewear designed primarily to prevent bright Sun light and high-energy visible light from damaging or discomforting the eyes.
  • Glasses tinted to protect the eyes from sunlight or glare
  • spectacles that are darkened or polarized to protect the eyes from the glare of the sun; "he was wearing a pair of mirrored shades"
  • Ascertain the size, amount, or degree of (something) by using an instrument or device marked in standard units or by comparing it with an object of known size
  • any maneuver made as part of progress toward a goal; "the situation called for strong measures"; "the police took steps to reduce crime"
  • how much there is or how many there are of something that you can quantify
  • determine the measurements of something or somebody, take measurements of; "Measure the length of the wall"
  • Be of (a specified size or degree)
  • Ascertain the size and proportions of (someone) in order to make or provide clothes for them
  • cover or stiffen or glaze a porous material with size or sizing (a glutinous substance)
  • the physical magnitude of something (how big it is); "a wolf is about the size of a large dog"
  • (used in combination) sized; "the economy-size package"; "average-size house"
  • Each of the classes, typically numbered, into which garments or other articles are divided according to how large they are
  • The relative extent of something; a thing's overall dimensions or magnitude; how big something is
  • Extensive dimensions or magnitude

The three elements are: ISO - the measure of a digital camera sensor’s sensitivity to light Aperture - the size of the opening in the lens when a picture is taken Shutter Speed - the amount of time that the shutter is open The Window Imagine your camera is like a window with shutters that open and close. Aperture is the size of the window. If it’s bigger more light gets through and the room is brighter. Shutter Speed is the amount of time that the shutters of the window are open. The longer you leave them open the more that comes in. Now imagine that you’re inside the room and are wearing sunglasses (hopefully this isn’t too much of a stretch). Your eyes become desensitized to the light that comes in (it’s like a low ISO). There are a number of ways of increasing the amount of light in the room (or at least how much it seems that there is. You could increase the time that the shutters are open (decrease shutter speed), you could increase the size of the window (increase aperture) or you could take off your sunglasses (make the ISO larger). Ok - it’s not the perfect illustration - but you get the idea. Another way that a friend recently shared with me is to think about digital camera exposure as being like getting a sun tan. Now getting a suntan is something I always wanted growing up - but unfortunately being very fair skinned it was something that I never really achieved. All I did was get burnt when I went out into the sun. In a sense your skin type is like an ISO rating. Some people are more sensitive to the sun than others. Shutter speed in this metaphor is like the length of time you spend out in the sun. The longer you spend in the sun the increased chances of you getting a tan (of course spending too long in the sun can mean being over exposed). Aperture is like sunscreen which you apply to your skin. Sunscreen blocks the sun at different rates depending upon it’s strength. Apply a high strength sunscreen and you decrease the amount of sunlight that gets through - and as a result even a person with highly sensitive skin can spend more time in the sun (ie decrease the Aperture and you can slow down shutter speed and/or decrease ISO). neither metaphor is perfect but both illustrate the interconnectedness of shutter speed, aperture and ISO on your digital camera. NB: A third metaphor that I’ve heard used is the Garden Hose (the width of the hose is aperture, the length that the hose is left on is shutter speed and the pressure of the water (the speed it gets through) is ISO. written by digital-photography-school

Field Bag
The contents of my field bag. Most of my traveling involves going from city to city or from town to town so I'm generally more equipped for an urban setting. However, I have been out in the city and then off into the country as soon as one of my friends says "I have this cool idea." Many a time, I have been mocked for carrying such a bag of infinite possibilities, but when my friends are in need and their eyes light up when I produce the 'thing' that they need - I'm usually not mocked twice.
