Part 4 – Project 1 – Exercise 4.1<\/h1>\n
Exercise 4.1<\/strong><\/div>\n
1. Set your camera to any of the auto or semi-auto modes. Photograph a dark tone (such as a black jacket), a mid-tone (the inside of a cereal packet traditionally makes a useful \u2018grey card\u2019) and a light tone (such as a sheet of white paper), making sure that the tone fills the viewfinder frame (it\u2019s not necessary to focus). Add the shots to your learning log with quick sketches of the histograms and your observations. You might be surprised to see that the histograms for each of the frames \u2013 black, grey and white \u2013 are the same. If there\u2019s not much tonal variation within the frame you\u2019ll see a narrow spike at the mid-tone; if there is tonal variation (such as detail) you\u2019ll see a more gentle curve. If you find the tone curve isn\u2019t centered on the mid-tone, make sure that you have your exposure compensation set to zero. You may see an unpleasant colour cast if you\u2019re shooting under artificial light, in which case you can repeat the exercise using your monochrome setting (a light meter is sensitive to brightness, not to colour). This simple exercise exposes the obvious flaw in calibrating the camera\u2019s light meter to the mid-tone. The meter can\u2019t know that a night scene is dark or a snow scene is light so it averages each exposure around the mid-tone and hopes for the best. But why can\u2019t the camera just measure the light as it is? The reason is that a camera measures reflected light \u2013 the light reflected from the subject, not incident light \u2013 the light falling on the subject. To measure the incident light you\u2019d have to walk over to the subject and hold an incident light meter (a hand- 78 Photography 1: Expressing your Vision held meter) pointing back towards the camera, which isn\u2019t always practical. If you did that each of the tones would be exposed correctly because the auto or semi-auto modes wouldn\u2019t try to compensate for the specific brightness of the subject.<\/div>\n

4.1.1.<\/strong><\/p>\n

\"\"<\/p>\n

As the exercise suggested the three items looks almost the same colour and the histograms are very similar.  This shows that if left to the camera, it will always try to make everything 50% grey or the mid tone.<\/p>\n

4.1.2<\/strong><\/p>\n

 Set your camera to manual mode. Now you can see your light meter! The mid- tone exposure is indicated by the \u20180\u2019 on the meter scale with darker or lighter exposures as \u2013 or + on either side. Repeat the exercise in manual mode, this time adjusting either your aperture or shutter to place the dark, mid and light tones at their correct positions on the histogram. The light and dark tones shouldn\u2019t fall off either the left or right side of the graph. Add the shots to your learning log with sketches of their histograms and your observations. Switching to manual mode disconnects the aperture, shutter and ISO so they\u2019re no longer linked. Because they\u2019re no longer reciprocal, you can make adjustments to any one of them without affecting the others.<\/p>\n

\"\"<\/p>\n

In manual mode, the shutter speed or aperture can be altered to get the correct exposure.  However, if you want the image to be darker and closer to the black range, you can slow the shutter or close the aperture until the midpoint on the camera moved to the left or (-) side.  The reverse is true if you want to lighten the image.<\/p>\n

Using manual mode gives you more control of the light that hits the sensor.  Of course you can also use the ISO to change this too <\/p>\n
