EOS RP 1.6.0 Experimental Log and Shutter Angle Tests
Build tester-01

Before you start

Use a Canon EOS RP running firmware 1.6.0, a body with the Magic
Lantern boot flag already enabled, and a spare FAT32 SD card already
marked bootable for Magic Lantern. A stock body needs separate guided
setup before it can load this build. Skip the camera's Firmware Update
menu for this test.

For a fresh spare card on a prepared body, format the card as FAT32
and mark it for Magic Lantern with a card tool such as EOScard for
Windows. Confirm the selected drive is the spare card and that both
EOS_DEVELOP and BOOTDISK are set. Formatting erases the card.
EOScard is available at https://eoscard.pel.hu/.

Copy the contents of SD-CARD to the root of the prepared SD card, so
autoexec.bin and the ML folder sit side by side. With the camera off,
insert the card and turn it on. From the shooting screen, press the
Trash button to open or close the Magic Lantern menu.

Test Canon Log

1. Set the camera to manual movie exposure at 4K 23.98p with ISO 400
   fixed. Use the Neutral Picture Style at saturation 0 as a baseline.
   Saturation -1 was also tested. In Magic Lantern's Movie
   tab, set Shutter angle to Off. Use 1/50 s and fixed white balance for
   the comparison. Keep the aperture, framing, and light steady.
2. Record a short clip with Movie > Canon Log set to Off. Stop, open
   Movie > Canon Log, and press SET. If live view resumes, reopen the
   menu to confirm the Movie row says On. The row shows Starting while
   setup is in progress.
3. Close the menu and record a short clip promptly. Stop and
   record a second clip with Canon Log still On. This tests quick
   starts and repeat takes. Check that the live view stays clear of
   Log status text. Stop, switch Canon Log Off with SET, then record a
   final stock clip at the same exposure.

The RP records the experimental Log image in its 8-bit MP4 files.
Canon Log starts Off on each power-up. For an optional report after
recording, open Debug > RP test features > Save Log diagnostics and
press SET. Keep the newest ML/LOGS/RPLOGxx.TXT with the matching clips.

Test shutter angle

1. Set Movie > Canon Log and Movie > Shutter angle to Off. Stay in
   4K 23.98p manual movie mode with fixed ISO, aperture, white balance
   and lighting. Set Canon's shutter speed to 1/100 s and record a short
   baseline clip. Leave enough room for a brighter exposure.
2. With recording stopped, highlight Movie > Angle (deg) and press SET
   to edit. Use LEFT/RIGHT to select a digit and turn the dial to change
   it. Press SET to finish. Set 180 degrees, switch Movie > Shutter angle
   to On, close the menu, and wait for Angle 180 in live view before
   recording. The Movie row also shows 180 degrees active. At 23.98p,
   180 degrees is about 1/48 s, so the clip should be brighter than
   the 1/100 s baseline under the same light.
3. Stop between clips and repeat at 181 and 182 degrees. Close the
   menu after each change and wait for the new angle to become active.
   The range is 90 to 300 degrees in 1-degree steps. For a flicker test,
   keep the screen content, refresh rate and camera settings fixed and
   compare the bands between short takes at neighboring angles.
4. Stop, set Shutter angle to Off, and return to live view. For a
   diagnostic, reopen Movie > Save angle log, press SET, and wait for
   Saved. Copy ML/LOGS/RPANGD5.TXT and note the angle for each clip.
   A later save replaces that file, so copy it before another run.

Return to stock operation

Turn the camera off, wait for card activity to stop, and swap in an
ordinary unmarked card before restarting. The body boot flag stays
enabled. Keep autoexec.bin on the test card while it is marked bootable.
If the camera hangs at startup, set the switch to Off. If it remains
unresponsive after card activity stops, remove the battery and test
card. Reinsert the battery and restart with the ordinary card.
