Transferring Lens Maps between LDT-R1 Units
If multiple LDT-R1s need to use the same lens tables, the LENSDATA file can be
copied onto the root of each MicroSD card and the LDT-R1 will automatically read
them.
Note: ​ B ackup the LENSDATA file on the MicroSD card to avoid data loss in case of
corruption.
Lens Database
If the user decides to not use F-Map the lens database can be organised as a list or
as folders.
● List: LDT-R1 display.
● Folder: LDT-R1 creates a folder structure based on lens brand, type and a
single file for each lens in the root of the MicroSD card.
DCS suggests using Folder mode.
Shooting a Test
When shooting test footage, allow approximately one hour per camera type being used on
the production. A test will involve recording the metadata (internally or injected) with a
camera and recording a separate feed from the camera with an overlay to verify the data is
correct at the final stage of the test. We recommend using a zoom lens (if any are being
used during the shoot) in order to check all three axes.
To do a test:
● Encode a lens and test it (see "Programming a New Lens Table"),
● Shoot test footage in camera and record separate overlay feed at the same time,
● Extract the CSV if using injection recording (see relevant camera in Appendix 5),
● Merge the CSV files to the EXR,
Compare the metadata of the EXR file to the overlay footage.
