Perhaps it is all just like shutter speeds that show up in Exif

I also found this after a bit of a search. Could however, completely confuse the issue - but it does make sense after a few reads through!

The aperture is the hole situated in the lens of the camera that controls the amount of light that is allowed to reach the sensor. Certain modes on a camera allow the user to change the size of the aperture therefore changing how much light is allowed through.
Apertures are represented by a series of numbers called f-stops, and, in reverse of what you might think, the larger the number, the smaller the hole. For example, an f-stop of f/2.8 would represent a large aperture and an f-stop of f/32 would represent a small aperture. As you can see from the illustration below, the largest hole is represented by the smallest number. Each subsequently higher f-stop number lets in half as much light as the previous number.
The f-stop of a lens is a number that represents the aperture opening. A large opening is a small f number, and a small opening is a large f stop. Lenses are rated in the range of f-stop numbers they can be set to. Pay particular attention to the lowest number. If a lens is rated, "f3 to f22," the f-3 is what you care about. This represents the lens' ability to pass light. The smaller the number the more light the lens can admit which improves the camera's ability to capture images in places with low light. Some of the best 35mm film cameras have lenses that are rated at around f1.2 and f1.8. In digital cameras you will do well to get a lens in the area of f2.8.
Simples eh!

From what I have read, contrast control, (where the output of two or more flashes is controlled) is only available when the flash unit(s) are hard wired with off camera flash cords etc

When I lived in the Maldives I used to keep my kit in a wardrobe with a 60w lightbulb on inside it. Just enough to keep the mould at bay!
Comment by mayday posted on Humidity and Fungus any ideas on how to reduce either? at 04/02/2010 - 11:34
Hi Tom,
That looks to be an excellent job - get it patented!! I expect Wimberley would say you nicked their idea though. I am sure you could make a few of these and members here would relieve you of them, because there are not too many "Good" gimble heads out there at a sensible price

I think I'd rather have the K 2000mm lens that mostly seems to have existed in the Pentax price lists. It looks like a waste paper bin with a K mount on one end!
