Effects of Exposure on the Quality of Photographs.
Exposure is an extremely crucial factor in digital photography because it is one of the main determinants of what will be recorded in real-time on the image sensor of a camera, and ultimately the shot which will be captured and produced.
The exposure of a scene to be captured is represented by a combination of the values of the above three elements and the resulting value from this combination is known as the Exposure Value.
If the setting of one element is adjusted, then it will impact on the working of the other two settings. This is because the shutter speed, aperture and ISO work dependently. Therefore, if you adjust one setting it is necessary to adjust one or both of the other elements so as to get the correct exposure value.
To become a professional in photography it is essential that you know how to control these three elements by adjusting the settings in a manner which enables the exposure to be optimum for capturing the best quality image.
In the meantime, whilst you are learning how to make the adjustments to the three elements of exposure, you can always use the automatic mode feature of your digital camera. This means that the camera does all the work for you, although you are a little limited if you want to create any special effects.
This post has been written with the purpose of helping you learn how to manually adjust the settings to achieve a quality shot.
Working with different Settings on the Elements.
One of the great advantages of having a digital camera is that you can experiment with the settings until you’re heart is content. As I have mentioned before, experimenting with different settings for yourself is one of the best ways to learn how to achieve an outstanding shot.
Whilst experimenting, keep a notepad handy (digital or old style) to write down which exposure settings that you used with each shot and then experiment with different adjustments.
Photography is the art of observation. It has little to do with the things
you see and everything to do with the way you see them.
Dr Halls Notes on Exposure
I think the secret of good photography, is buying a really good camera, and good big lenses. I have a canon eos 7d mark2, and a 70-200mm lens, which I love. People ask me, are you a professional, and I’m not, and I don’t care. It’s just a great camera, that I leave on automatic nearly all the time. Another secret, it is to take a lot of photographs. Be snapping them all the time, and throw away most of them, but you just never know where the best and most interesting things are going to be.
