Some MUWians have PM or FBied Ketam asking about settings and distance. For this trip was playing a lot with shallow depth of field....

f3.5 1/500 iso 80

f4.5 1/500 iso 80
for bigger nudis and more depth ketam would use f8. Shutter of 1/500 is the sync speed of the G10 and Ketam prefer to control the strobe manually.
For distance, it is based on the subject. The aperture will limit your focal length and you move the camera closer or farther from the subject until you get a good focus. Ketamnette got some images below.



Hope this helps.
