Wikipedia has good description about it. It is also called  F-Stop . This pic is from Wiki. F-Stop = Focal Length / Diameter of the hole through which light comes (Aperture). In other words F-stop = F/A As the above answer explains well, 1 stop = double the light 2 stop = 2*2 = 4 Times the light 3 stop = 2*2*2 = 8 times the light So to change from ISO200->ISO400 is one stop. ISO200-ISO800 is two stops and so forth. Another way of showing stops is by means of focal length, as show in the pic one stop = f/5.6 two stop = f/4 three stop = f/2.8 Why is the denominator not the whole number? This is because it is the ration of area. And the ra...

Always youSince we met you give me your handTo embrance a new form of realityThe truth is, i dont know why i ignored itSide by side we walk together in this new land A new world full of dreams and oportunity You push me harder until i realise it What is corrected to me, to us and our love It was harder than everything before To look deeper into your blue eyes Understanding and forcing me to see a white dove In that moment i felt we are already far away from the shore Where i started to see and feel your tries Now we are connected and married as one Living our true magic by our true expression  Inside and outside of us we do everything unti...
