In photography, how does one attain the depth of field?

In photography the aperture controls the depth of field of an image. The aperture is the size of the opening of the hole created by the iris. The iris works in the same way the one if your eye does.It closes to make a smaller hole and widens to make a larger hole.

The aperture openings are logarithmic in nature. They are measured in f-stops The larger the f-stop number the smaller the aperture is.So an aperture of f-11 is one stop smaller than an aperture of f-8. However and aperture of f-8 lets in twice as much light.

The smaller the aperture is the greater the depth of field is.So if you need a great depth of field, you need to stop down the lens. You then need to adjust shutter speed and ISO sensitivity to get good exposures. Both he Sony Sony NEX-5 with 1440-7200mm Zoom Lens and a 50mm 1.2 lens use the same aperture controls for depth of field.

Comparing these two lenses is like comparing a Ford to the Space Shuttle. The Sony lens opens up to an aperture of 2.8 and the other lens to 1.2 so they are one f-stop difference in the widest aperture but they both stop down to f-64.

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.
