It has been quite rightly pointed out that there is no suitable place for non-beginners to discuss ways of improving their picture taking and camera technique. So here it is! For more basic help and encouragement of beginners, please continue to use the Help and advice for beginners board.
Hi....progressing ok. I have seen some folk use low f numbers for landscapes. This seems a little counterintuitive. What are the advantages of using ..say f /3.5 for the situations ( over , say f/8 ?

It depends on which format (sensor size) they are using and what effects they wish to achieve.
For example, many photographers now use cameras with a Four Thirds sensor, which is roughly a quarter of the surface area of a sensor used in a "full frame" camera. Generally, the smaller the sensor, the greater the depth of field at any given f-stop. With a Four Thirds camera, apertures tend to have similar depth of field characteristics to those with two numerical f-stops higher on full frame cameras. Thus, f3.5 has approximately the same depth of field as f7 and f4 the same as f8.
However, there may be a reason for using a large aperture (small f-stop) with a full frame camera. Rather than seeking sharpness throughout the whole scene, a photographer may decide to blur, say, the distant mountains but keep in sharp focus the foreground flowers/grasses/rocks/stream in order to emphasise these features. It might not be the traditional technique associated with the classic landscape view, but who's to say we can't try to be creative?
