F stop. Each lens if fixed in the camera or removable depending on its characteristics has a number of F stops.

Basically an F2, for instance, is when the lens is opened up to allow the maximum light into the lens. Then the time the shutter is open to take the picture is very fast.

On the other hand F16 the lens is closed down to a pin point. To allow light in the speed the picture is taken is very slow.

F16 will give a greater depth of field. F2 the depth of field will be shorter. If you focus correctly on a subject then there is a distance in front and behind that point of exact focus where the background and foreground are relatively in focus.  The depth of field one third in front of the subject two thirds behind approx.

Each lens has an Fstop which is the best optics point and will produce the best in terms of quality of picture. My camera main lens is best at an Fstop of F11. There is a considerable difference in the quality of picture from F11 to one taken at F2.

However at F11 where light is not so good as say F2 the lens is open longer to take the picture and therefore camera shake enters the picture literally. This is where the tripod is necessary. Providing the subject is static you will then get an optimum picture. If the subject is moving then you will have to resort to the F2 end of the stops to take a picture with the lens open for a minimum length of time.

Hope that makes sense. Apologies for all those who are aware of these details. I am am not a skilled photographer however I ran at one time a video film making company. The principles are the same in video which is just taking continuous still photos at enormous speed.

On lighting. I have recently changed all bulbs in my model making dive to LED daylight (6000K (kelvin). This is a white light on the blueish side. Average domestic bulbs are approx 3000K and give a yellowish light. Colour matching is more accurate with the daylight bulbs. Added plus LED's last in the region of 50,000 hours and use less than 10% of an ordinary bulb.

Cheers Laurie, it's very helpful of you to explain what the numbers mean,
if I can quantify it I can understand it a bit quicker [smile].
