This lesson our task was to set our cameras to program mode, then go out and change the levels.
this is an over exposed photo and as you can see the majority of the tone is highlight tone. This is made by turning the level up on the camera, to make sure it will be over exposed, look at the camera screen and see that it's more on the positive side.
This one is under exposedand as you can see by the histogram, the majority of the tone is in the shadow side of the tone measure. This is created by turning down the level on the camera, so that it shows on the negative side.
this photo is a fairly normaly exposed, although the tones are still quite near the shadow side of the tone metre, with a little amount over the mid-point. The only reason why it has more dark colours is because this was a close up. So if I would have just taken a photo of the college in over, correct and under exposure, the normally exposed image would have a roughly equal levels, so it would look reasonably balanced.
Evaluation
For this experiment I used a camera and a SD card. This experiment went very well, apart from when Photoshop crashed on me, but thankfully I'd saved my work three steps before that so, not too much work was lost. The part that went well the most was taking the photos, it really is so simple when you know how. I could have refined my work by using the high pass filter to enhance and sharpen the image. At the time I took this I wasn't aware of this refining technique, so that is why I didn't apply it.
