Wk 5 - Evaluative metering

We've been working in manual mode for a week.  I must say i do miss the priority modes because of their automatic functions.  I feel like such a newbie , i'm still finding my feet with all the functions of the camera i'm really glad we have the internet to dive into.  It's been a great tool to use paired with class content.  This way of learning is really beneficial to me.  My two go to sites are Digital Photography school which have heaps of tips and tutorials from a wide range of photographers and Eric Kim's Blog which provide a lot of tips, information and inspiration especially for new photographers.  I stumbled onto Eric Kim when i was doing research on my one of my weekly artists.  

With my photos, i've been sticking with the evaluative metering mode.  We have been asked to try out some of the other metering modes.  On the camera i am using - Canon EOS 1100, there are three metering modes, evaluative, partial and centre weighted.  Others have a four option called spot metering.  When in these modes the camera gives a meter which measures the reflected light.  To get the right exposure you need to ensure to place the arrow on to the 0 any numbers before the 0 will equate to an underexposed shot and any numbers after the 0 will equate to an overexposed shot.




The photos below are low angle portraits of my subject infront of the sun using the different metering modes:

f/5.6, 1/320, ISO 100
f/5.6, 1/320, ISO 100

Evaluative metering mode -The meter divides the scene up into zones, then analyzes each zone for highlight and shadow.  Then it takes an average for all the zones and determines the exposure based on that figure.

The subject is placed with the sun behind her.  In the evaluative metering mode the front of the subject is lit well.  The background seemed balanced and the rim light on her hair is very apparent.

f/5.6, 1/320, ISO 100
Partial metering mode - The light in a smaller part of the scene is measured and the exposure is set based on that reading.  Effective when the background is much brighter than the subject. 

The readings were the same as the evaluative metering mode.
f/5.6, 1/800, ISO 100
f/5.6, 1/500, ISO 100
Centreweighted-Average metering mode - metering is weighted at the centre and then averaged for the entire scene.  This metering mode focus' attention to correctly exposing the subject.
