Depth of field in Canon Powershot SX30 IS?

I always use aperture priority. That is A on the dial. Then use the lowest f number it will let you use, for instance f4.5.Make sure to use a medium to long zoom for increased blur of background, provided it is far back from your subject.

DOF - Depth Of Field DOF is the area (plane) of the photo that is in sharp focus. For landscapes, we usually want a a very deep DOF, so that everything in it is in focus. For portraits, we usually like to have the person in focus, while the background is blurred.So you have a plane that is in focus - and it can be either in the foreground (so the background is blurry) or in the background (so the foreground is blurry).

To achieve a shallow DOF (for background blur and/or bokeh), you need the following : 1) a lens with a large aperture (f/1.8 or f/2.8 work best) 2) longer focal lengths - the longer it is, the stronger the effect becomes 3) distance - a subject that is CLOSE, a background that is further away. Often people ask how to achieve with a small P&S camera, but unfortunately that is not something those little things are very good at because of their VERY TINY sensor. Even some of the better bridge camera still have MUCH smaller sensors than a DSLR does.

If you have manual controls, use the biggest aperture. If you don't, try setting it to the portrait setting which makes the camera choose the biggest aperture it is capable of. Make sure there is some distance between you, the subject, and the background.

You can also attempt it on Macro setting - that may work to a certain extent. For further reading, check out this Wikipedia article: http://en.wikipedia.org/wiki/Depth_of_fi….

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
