 ETTR works best with Intervalometer. Set ETTR option "Always On". Adjust aperture or use ND filter to get exposure times above 0.5 seconds. Otherwise results may be impossible to deflicker in postprocessing. Don't forget Silent pic and Intervalometer are using the same default trigger. Change Intervalometer trigger to "Leave menu" to avoid this.
