The 3 basic of Exposure:
- Aperture – The opening in the lens which light comes through. It is measured in f-stops.
- Shutter Speed – How long the sensor is exposed to light. Measured in seconds. Fast shutter speed makes a freeze fame image of motion, slow shutter speed makes blurry motion.
- ISO – Controls how much light the sensor needs to make the image. The higher you set the ISO more gain will be in your image.
Why using RAW pictures is better:
RAW captures all of the image information recorded by the sensor when you take the photo. Shooting in RAW is always better than JPEG because in JPEG the information is compressed and lost. RAW gives you a higher quality image every time. You can easily change the exposure, white balance, etc. with just a couple clicks when you open the file with RAW in Photoshop. The higher quality the file the more detail the file has. It is a way of non-destructive editing, that way if you mess up your file is not ruined forever. Plus RAW allows for a better workflow, why spend hours editing a JPEG when you can spend a minute or two editing a RAW file.

Research about Rule Of Third (Photography):
You break down a photo into thirds both vertically and horizontally. In theory to make your photos interesting you put your subject where the lines intersect. If you happen to forget about the rule of thirds while you are taking the photo you can always use the rule while you are editing your image.
