A funny yet informative beginner's guide to photography

Only people can have moods, the camera is so amazing it has all the traits of human beings and their eyes.

Talking about the digital camera (since the everyone is going digital)….

The angle of view depends on the type of lens we attach to the camera and the type of sensor present inside the camera's body.

Generally, our eyes have an angle of view to that of the 50 mm lens on a full-frame body.  Full frames are professional grade cameras.  Consumer cameras have cropped sensors by a factor of 1.5 to 2, that means they are smaller and the angle of view of the lens is multiplied by that factor.  Thus, a 50 mm on a cropped sensor body (DX in Nikon, APS-C 1.6x in Canon) has an angle of view of a lens of 75 mm or 80 mm on a full-frame body. [D-SLR camera bodies]

# Iris: Diaphragm of the aperture of a lens, made from several moving blades to change to size of the aperture as required.

# Pupil: The aperture through which the amount of light entering or the depth-of-field can be controlled.

# Lens: The lens of an eye can be compared to the focusing mechanism of a camera lens. To produce sharp results the lens needs to focus properly. Technically, the further the focusing elements of a camera lens the closer the object is and vis-a-versa.

# Retina: The focal plane or the sensor on which the image is created for recording, generally made from CMOS (Complementary Metal Oxide Semiconductor).

# Chemicals: If the eye is subject to extreme darkness or extreme brightness certain chemical produced help with the sensitivity to light. This is better known as ISO-Speed in cameras. The higher the ISO speed the better the camera can 'see' in darkness, with some side effects, of course.

# Eye-lids: Try blinking your eyes twice!  What happened between the two blinks? That is exactly what the shutter does, and that is how much light the sensor captures in the blink of an eye, yet producing perfectly lit and vibrant photos.  Have I mentioned the camera is an amazing thing?

# Brain: The processor and the storage media of a camera.

Please wait there's more…

The different moods of a camera are just like the faces of human moods, also called P-SAM:

# Auto:  Here is when the camera is most stubborn, like a child, will not change any setting related to exposure, will choose its own settings.  Wondered why they call the auto mode point-and-shoot?

# P (Programmable Auto):  This is a much co-operating version of the auto mode, here you can change the ISO-speed, and the aperture sometimes; but since the shutter speeds also change accordingly, the overall exposure remains the same.

# S (Shutter Speed) or Tv (Time Value): So after you have given the child some understanding of how you want things done, he agrees to you to co-operate a bit more, but only if you promise to do a few things for it.  This mood will let you choose the amount of time the shutter will stay open, that means the longer it remains open more the exposure to light the sensor will get, you can change the ISO-Speed here too, but the camera still controls the aperture.

# A (Aperture) or Av (Aperture Value): Now you exchange a few more things with the child, and you control a new thing, but you lose control over the former.  Here, you control the aperture, thus allowing how much light would enter through the lens, and control the ISO-Speed, but the camera retains the control of shutter speed.

# M (Manual Mode, Mature Mode): After learning and growing up about life, the child now gives up on all things held so dear.  Here, you can change the ISO-Speed, the Aperture as well as the Shutter Speed, this is when you have the complete creative control of your amazing child – the Camera.

Hope you have enjoyed reading a short analogy of the Camera and its Moods….
