P1
quality
NO-HDR ISO 100
Duration : 36s
For all programs the exposure is read by the VR Drive Metric light meter and set via USB control
on the camera. The USB connection is also used to release the images, for release control and
for writing capture information into image metadata.
To guarantee large and consistent depth of field the aperture (f-stop) of the camera is always
fixed to f=11.
The indicated program durations are estimates and depend on available light. The above
examples are correct for daylight conditions (fast exposure speeds). When shooting indoors
image capture may take longer – depending on choice of ISO/ASA.
Capturing the images with low ISO/ASA provides better quality images (less noise). This
is a benefit when using the spheres for 3D measurement applications. For 3D
measurement projects please always use ISO/ASA=100 (P1, P3, P5 or P7 only).
We can provide special programs for image capture at higher ISOs. However, the
spheres created with such high ISO values will not be suitable for 3D applications.
Please contact us by email to obtain these programs and follow the instructions for
importing the programs provided in this instruction manual.
