4.10 … create turntable scans (continued)
In turntable mode the sharpness of the image is not defined by the
focussing on the lens but rather by the accurate position of the camera
on the bench. If the image is slightly blurred it is possible to move the
camera on the bench slightly during a scan to optimise the sharpness.
Setting the focussing distance on the lens has an influence only on the
zoom ratio and not on the image sharpness. It is therefore not necessary to
have a high precision is setting this value on the lens.
4.10.2 Software adjustments (continued)
• Macro tubes: defines the number and the
size of macro tubes to be used. In this
example one 16mm and two 52mm tubes
should be attached to the lens to obtain the
desired zoom ratio.
• Focusing distance: defines the focusing
distance that needs to be set on the lens.
Please note that the distance setting in “shoot
settings” is now removed. In turntable mode
the focusing distance is defined by the
software according to the zoom ratio.
• b-value: defines where to position the
camera body on the scale of the turntable
bench.
The object height corresponds to the size of the area to be projected on
the entire sensor i.e. 60mm. This means that if the entered value is 60mm
the zoom ratio will be 1. if the value entered is lower the zoom ratio will
increase and more details will be visible on the surface.
This means that the object height should be used to specify the desired
zoom ratio on the object rather than the effective object size.
When all software and hardware parameters are set correctly, press start to
