THESE ARE MY OWN NOTES/OBSERVATIONS THEREFORE IF YOU SPOT AN ERROR - PLEASE LET ME KNOW SO THAT IT CAN BE CORRECTED!
We have looked at 'A' on our camera (If you have this or similar) for Aperture. It is sometimes 'AV'. This controls the amount of light that comes through the lens. The higher the number the more you get in focus. The lower the number the less you have in focus.
Therefore if you want to highlight the foreground and blur the background use a lower number which lets in more light. If you want the foreground and background use a higher number which lets in less light.
This setting is good for: -
- portraits where it is best to use a smaller number - which blurs the background - ensure you get the eyes in focus!
- landscapes where it is best to use a larger number to see more background.
Have a look at this very useful web page
The higher the number, the more noise (grainy) the picture is. The lower the number the better the quality of picture. This setting affects the quality of light - use a higher ISO inside (especially when not using a flash). For sunset/sunrise try 100/200
We have also looked at S - Speed. On this setting your camera will determine what is the best Aperture.
- 1/4000 is fast and good for sport/wildlife/moving subjects/running water etc to make them look still.
- 30" (= 30 seconds) is slow and best on a tripod. Good for landscapes, show movement i.e. traffic, moving water shows as a mist, and light painting - which we had a go at with a moving candle.
To make water 'still' put IOS to 100 shutter speed to slowest (i.e. 30") however you will need to use a tripod.
