First Meeting 1-11-09

What a great day.  THANK YOU TO EVERYONE who came!  Way to go... we're bursting out of our first room... 

Our Club Calendar:

JAN 11 White Balance & the Exposure Triangle

FEB  8 Portrait work and Family Settings/Shots

MAR 8 Travel & Architecture/City Life Shots 

APRIL 12 Flowers/Fauna Shooting flowers like a pro (maybe a road trip to the tulip fields in the Skagit Valley)

MAY 10 ACTION SHOTS sports etc.  Learn to pan etc.

JUNE 14 TBD

Here are some facts we covered in today's class:

White Balance: 

AWB/CUSTOM/TUNGSTEN/FLOURESCENT/DAYLIGHT/FLASH/CLOUDY/SHADE 

what's the right one to choose for your setting?  Is it ok to let the camera be automatic on this one?  Yes it is.  I would say 90% my camera picks the best one.  But the other 10% I end up choosing something different becuase the camera is metering off of something I don't want it to. 

 

Exposure Triangle:

1.   Aperture...lens opening...f-stop

2.  ISO...film speed...the higher the number the faster the speed of your film/sensitivity of your         sensor to light.  The lower the number the slower the speed of your film/sensitivity of your           sensor to light.  100 (speed) Bright Sunlight  2600 (speed) dark 

3.  Shutter Speed...the amound of time your shutter stays open during your exposure.

These 3 factors are called the Exposure Triangle.

With film, you were stuck with a constant film speed depending on the film you placed in your camera.  In digital you can change your ISO setting for each exposure.

Aperture and shutter speed function reciprocally.  Each doubling or halving of aperture or

 shutter speed represents a one stop change in either aperture or shutter speed.

So Bottom Line:

APERTURE:

stepping down (more light in) f1.4  f2  f2.8  f4  f5.6  f8  f11  f16  f22 stepping up (less light in) 

maller depth of field range                                                                     larger depth of field range

SHUTTER SPEED:

stepping down (more light) 1/4  1/8  1/15   1/30  1/60  1/125  1/250 1/500 (stepping up) less light

more blurred moving subjects                                                     less blurred moving subjects

Don't forget Brad's great analogy of the PIE shape.  Split a pie 3 ways.  If you make one section of the pie smaller (like the Aperture) the ISO or the Shutter Speed have to become bigger to continue to make a whole pie.

Thanks again for a great class everyone.
