+==== Aperture flicker ====
+Unwanted effect in time-lapse recordings caused by small variations in aperture actuation from selected aperture number. \\
+Every time a pic is taken, aperture blades will move from "open" to selected aperture and back. Consumer lenses with electronically controlled aperture blades are generally not able to repeat aperture actuation with infinite precision. Thus small but noticeable variations in exposure may result in displeasing flicker.
+Workarounds to avoid aperture flicker:\\
+- Use manual lenses\\
+- Use electronic lenses wide open only. (No aperture blades moving -> no aperture variation)\\
+- Use electronic lenses but twist lens in mount while DOF preview is activated. Aperture blades will be locked in position -> no aperture variation. Take care to avoid lens getting completely unlocked and falling off the camera.

 There are some major diffences how PowerShot and EOS have to be programmed and that is why there are 2 different project teams.\\
-It may confuse some people that there are a few EOS M cameras not handled by ML but CHDK. And there are 4 PowerShot cameras not located in CHDK realm but ML. Those cameras run code contrary to their names!\\

 EOS M3, M5, M6, M10, M100 work with PowerShot firmware and are therefore handled by CHDK.\\
-PowerShot SX70, SX740, G5 X Mark II, G7 X Mark III work with EOS firmware and can be ported to ML.

+==== Event Procedure ====
+A function in the Canon firmware that can be called by string value. They can be executed with [[#canon_basic_scripting|Canon Basic scripts]], through [[#usb|PTP]], or through the //call// function in C. Internally, these are known as //evprocs//.

 Physically accessing UART in older cams required opening cam and maybe even soldering wires to camera's cirtuit board. Later cams have a UART connector on board for easier access. \\
 On some of Canon's Digic 7, 8 and X cameras this UART is accessible without opening the camera by just removing a reusable rubber cover.
+==== USB ====
+Generally used for debugging. Information is transmitted over the Picture Transfer Protocol. Canon
+has added several commands alongside the standard ones, such as the one that can be used to write the [[#bootflag]] (See https://github.com/petabyt/mlinstall)
