More model informationTest of methodology preparing for detail acquisition at Heritage Site. This an area approximately 25mm across. Acquisition with 4X microscope objective on full frame DSLR. 1068 images processed into 43 focus stacked images. Focus shift steps of approximately 0.15 mm. Lateral and vertical shifts for processing overlap of approximately 2.5 mm. Field of view with the objective lens onto the camera sensor is 14mm resulting in approximately 2.6 magnification onto the sensor.
This is a very fine sandstone with the lichen, in this case closely adjacent to the petroglyphs.
