Manual camera settings

The light meter
The light meter is used whilst taking a photograph to make sure that the image is correctly exposed, for it to be correctly exposed the arrow has to be on zero. If the arrow is below zero which is to the left this means the image is under exposed and if it is above zero which is to the right the image will be over exposed. To get the correct exposure the aperture, shutter speed and ISO all have to be correctly in sync whilst using the light meter to make sure these settings are correct to have the right exposure.

For this experimental task we looked at getting correct exposures using the cameras built in light meter.

First off I was asked to set my camera to manual and select the appropriate ISO for the lighting conditions, using the light meter to take a correctly exposed photograph. I started off by setting the shutter speed to 1/60, the aperture to f5 and the ISO on 800, whilst taking this photograph I made sure that the light meter was on 0 to make sure that this photograph was correctly exposed.

Then for the task I was set I had to under expose the image changing the aperture. Which I did keeping the shutter speed at 1/60, the ISO at 800 and changing the aperture to f13 which gave me this under exposed image by making the aperture smaller, to make sure this image was under exposed I have to make sure the arrow was below 0 on the light meter.






For the second task of this section I was then asked to over expose the image also changing the aperture only, but with the aperture on the highest it could go on I could not get an image over exposed by only changing the aperture, so i changed the ISO to 3200, with the aperture on f4.8 and keeping the shutter speed on 1/60, to make sure this image was over exposed I made sure that the was over 0 on the light meter.

For the next set of tasks I was asked to revert back to the correct exposure settings, then take an under exposed image changing only the shutter speed, I changed the shutter speed to 1/640, with the aperture on f8 and the ISO on 800, with these settings I was able to get an under exposed image by changing the shutter speed and making it faster which allows in less light.




Secondly I was asked to take an over exposed image using the same rule of only changing the shutter speed. To do this I changed the shutter speed to 1/30 and kept the aperture at f5 and ISO at 800 and with these settings I was able to get an under exposed image by changing the shutter speed to make it slower which allows in more light.

For the last set of tasks I was asked to revert back to the correct exposure settings and this time taking and under exposed image changing only the ISO. So using a shutter speed of 1/60 and an aperture of f5, I changed the ISO to 100 I was able to create the this under exposed image by only lowering the ISO.






Lastly, using the same rule of changing the ISO only, I was asked to take an over exposed image. To get this image I changed the ISO to 3200 with a shutter speed of 1/60 and aperture of f5.6 and with these settings I was able to get this over exposed image by choosing a higher ISO number.
