Thanks must be given to Rainbow Camera Club member, Deirdre Dillon Malone, who gave the members present a very informative demonstration on the effects of using different Aperture settings.
As can be seen in the photo below, using a large aperture (a smaller "F" number) means that only a small range of the image will be in focus, whereas using a small aperture (a larger "F" number) means that more of the image will be in focus.
This effect is often referred to as the Depth of Field. So, to get a greater depth of field (perhaps when photographing a landscape) it will be necessary to close the aperture down (use a large F number - or F-stop). When you want to make one object stand out (with the rest of the objects in the photo being out of focus and therefore less distracting) you will need to open the aperture (use a small F number). This can be particularly effective when you are taking a portrait shot of a single person.
In next month's meeting Rainbow Camera Club member, Pat Mullan will give a demonstration to the members present on Shutter Speed.
Finally, just a quick reminder that the motivational theme for this month is "The Sky". A reminder about this will be emailed to members a week or so before the next meeting, which will be held in The Cabin, Rossinver, Co Leitrim on Thursday, 9th May 2013, from 8 to 10pm.
