hiya gang
over the last few nights while on 12 hour night shifts i have been reading this book
http://www.waterstones.com/watersto...igital+photography+-+an+introduction/7246522/
now then the book is split in to chapters and each page/secetion of the chapter deals with a diffrent aspect of photography
now the first chapter is called the fundermentals and the third aspect is called focasing and depth of field
now while i have been reading this i have been taking notes on what i have learnt now i just want to check that i have picked up what he (the auther) is saying correctly, so what i am going to do is right my notes out and i just would like to know if they are correct or i have miss understood.
now
aperture: means the size of hole in the lens which light has to travel though in order to get to the sensor and its recognised measure is F now if the above is correct the smaller f is the further away a subject appears I.E the further you have zoomed out this also means that the hole in the lens will be alot bigger because you have zoomed out and f is smaller.
i.e the hole in the lens which the light has to pass through is bigger
now if all of that is true and i really have learnt it correctly that must mean that depth of field means the distance between the top blurry bit of the picture and the bottom blurry bit of the picture. Now i appreciate that not all pictures have a top blurry bit and a bottom burry bit but i find that, that is the easiest way to understand depth of field, if i am correct.
is this correct so far
