David’s careful packing worked well:
Using the Nikon Z6
Published December 29, 2020 / by Kirk MartinezThe newer mirror-less cameras have a few features which make them ideal for use in RTI imaging. Apart from the lack of mirror-flip for each frame (and possible vibration) they tend to have faster memory cards (CF express) so the system needs to wait less for images to be flushed to the card. Live preview with zoom also makes it easy to focus. I used a F to Z converter for a 105mm macro, which is manual only and the converter acts as the mount point for the whole camera.
Settings I used were saved in U3: Manual socus and exposure, fixed 100 ASA, stabilisation OFF, Silent ON, fixed white balance (use grey card), Picture Control normal (all zero) and auto-playback off. I left auto-distortion correction on as the cameras tend to know the characteristics of each lens.
Dome13 completed
