expert, but I like to share what I know and if I am wrong I invite you to correct me.
Here I would like to share the basics of exposure. Before we start, if you do not know what an exposure meter looks like then take a look at the picture below. This is the built-in exposure meter (or something similar) that you will see in the viewfinder of your new camera (if you do not know what is a viewfinder, I suggest a trip to some pages on the User Guide of your camera will do some good).
You will see a plus and minus sign. This shows whether the picture you are trying to take is currently in the right exposure. Adjustments are usually made if the exposure is not centered on the bar.
3 main functions in a DSLR controls exposure. They are:
- ISO
- Shutter speed
- Aperture
These 3 functions control the exposure (amount of light) in different ways. ISO controls light by adjusting the sensitivity of the sensor/film. Shutter speed uses time to control the amount of light hitting the sensor/film. Aperture uses different opening sizes to control amount of light entering.
By varying these 3 controls, you can adjust for correct exposure.
Of course each of these controls have different effect on light, therefore it will be interesting to adjust for the right exposure and vary your settings to see what kind of effects you will obtain.
I hope you found this article useful. Have fun experimenting!
