<span>1. Why is photographing lightning a difficult process?
</span>Some reasons which come to my mind for saying this are: 1) You get only one chance for the particular situation - it is not like portrait photography where you can go back in the studio if the photos didn't come out well; 2) lightning varies so much in brightness, intensity and location that guessing the proper exposure requires a lot of experience, as well as luck; 3) you are always at some risk when photographing worthwhile lightning; and 4) lightning is a point (line) source, and demands the most of the optical quality of your camera

2. What piece of equipment is helpful in capturing lightning photographs?
</span><span><span>SLR camera with B-shutter speed (preferably SLR; you might try using your digital camera, if it has B mode, but this is much more difficult)</span><span>lenses ranging from 28mm to 135mm at minimum. Fixed-focal lenses are preferred over zoomlenses. Aperture ranges should be f/2.8 - f/22.</span><span>sturdy tripod (metal or plastic doesn't make any difference whatsoever at all in safety - if lightning is so close by, you are in trouble anyway)</span><span>cable release, which can be locked</span><span>Slow-speed film: 100 or 200 ISO

3. Why is it important to mentally prepare for photographing lightning?

Answer:
Explanation:
try
clc
clear
close all
x=linspace(0,2*pi,7);
z=cos(pi.*x./3)
% the output on mine is to 4 decimals so it looks a bit different than what the output on your example is , but, I think if you change the format to decimal 2 it will look the same :)
