Highlight Tone Priority (which increases dynamic range by 1 stop in movie mode);

ISO selection (Canon ISOs or ML ISOs) – only used in movie mode;

Notes and tips for ML digital ISO, in movie mode only:

• Negative values will reduce noise, but may cause color issues in highlights (pink highlights).

• Positive values will increase noise, but in very dark scenes they will also get more shadow detail (at the cost of clipped highlights).

• Consider using negative ISO when you notice noise in shadows or when you want a smooth highlight rolloff.

• Try to use as much negative ISO gain as possible, but without getting pink highlights (-0.3 EV will probably work best; if you use HTP you may go up to -1 EV).

• For increased dynamic range, combine negative digital ISO (which reduces shadow noise) with the excellent Flaat picture styles (which are a very good approximation of log-gamma curves).

Shutter

Fine-tune shutter speed.

• When exposure override is enabled, you can adjust it in 1/8-stop increments (movie mode only).

• In photo mode, Magic Lantern displays integer shutter values without rounding them (e.g. 1/50 will be displayed by ML as 1/48). This is not a bug.

• In movie mode, shutter values are displayed with one decimal place (for example, in PAL mode, Canon uses 1/33.3 to avoid flicker).

• To use shutter speeds normally not available in Canon firmware (like 1/25 or 1/8000 in movie mode), enable exposure override.

Aperture

Adjust aperture. When exposure override is enabled, you can adjust it in 1/8-stop increments (movie mode only).

PictureStyle

Change picture style or adjust its parameters.

REC PicStyle

You can use a different picture style when recording (toggled automagically). May be useful with flat picture styles.

Exp.Override

This mode bypasses Canon exposure limitations (for ISO, Tv, Av). It enables:

• Manual video exposure controls in cameras without it (500D, 50D, 1100D).

• 1/25s in movie mode (24p/25p) → 1/3 stops better in low light.

• 1/8000s in movie mode, useful for slow motion.

• ISO 12800 is allowed in movie mode on 60D and 600D.

• Full-time DOF preview in photo mode, without blocking certain keys.

Settings:

OFF: Canon default exposure mode.

ON: ML overrides exposure values (change them from Expo menu).

Auto: ML enables it only when needed (that’s not auto exposure, but automatic decision of when you need low-level manual controls):

– For 500D, 50D, 1100D: in movie mode, to enable manual exposure controls.

– For 60D: in Manual mode with a manual lens, to fix the LiveView underexposure bug.

– For 550D/60D/600D/5D2: when you select a shutter speed, aperture or ISO value which is not available in standard firmware (e.g. 1/25s or 1/8000s in movie mode).

Side effect: in photo mode, anything slower than 1/30s will be underexposed in LiveView.

LV Display

Selects or displays LiveView display type:

Photo display, with exposure simulation

Photo display, without exposure simulation (for framing and for flash photography)

Movie display.

Overlay

Graphics overlays for LiveView or image review mode: histograms, zebras, focus peaking…

Global Draw

Choose when to enable Magic Lantern overlay graphics: (zebra, cropmarks, histograms, audio meters, ML shooting info…):

• in LiveView only;

• in QuickReview (photo mode outside LiveView) only;

Both modes (default);

Disabled.

If you use display presets, press Q on this item to switch the presets while you are in ML menu.

Zebras

Enable/disable zebra stripes, which indicate overexposed or underexposed areas.

Color spaces:

Luma: zebras are computed from Y channel only.

RGB: check overexposure for each RGB channel. Clipped channels are displayed in the opposite color (i.e. clipped red shown as cyan, underexposed as white and so on).

You may adjust thresholds for underexposure and overexposure, or you can disable zebras while recording.

Note: when using the Technicolor CineStyle picture style, luma will have values between 16 and 255; therefore, you will have to set the underexposure threshold to 16 or greater.

Focus Peak

Focus assist function. High-contrast lines will be marked by blinking dots showing which part of the image is in focus.

Methods:

• D1xy: computes first image derivative on X and Y and takes the max value. May work better in low light or on noisy sensors.

• D2xy: approximates second image derivative with a 3x3 Laplacian kernel. May be more accurate in good light.

Other parameters:

Threshold: how many pixels are considered in focus (percentage).

Color: either fixed color, or a color coding according to focus intensity.

Grayscale img: if enabled, LiveView will displayed as grayscale (but still recorded as color).

To see how it works, check this article from Luminous Landscape.

Magic Zoom

Displays a zoom box for focus assist. Can be used while recording.

Trigger modes (not all modes are available on all cameras):

HalfShutter: triggered when you press the shutter button halfway.

Focus Ring: triggered by turning the focus ring.

Zoom.REC: triggered by pressing Zoom In button while recording. If your camera has a LCD sensor, you may also cover it and press Zoom In.

FocusR+HalfS: triggered by turning the focus ring, or by pressing shutter halfway.

Focus+ZREC: triggered by turning the focus ring, or by pressing Zoom In while recording.

Zoom In (+): triggered by Zoom In button (overrides Canon’s default zoom modes). To bypass magic zoom, press both zoom buttons at the same time or cover the LCD sensor.

Always On: no trigger key needed. You can use both Canon’s 5x/10x zoom and Magic Zoom.

When ML believes you have achieved perfect focus, Magic Zoom will display a focus confirmation (customizable):

Green Bars

Split Screen: when the image is out of focus, the zoom box looks like a split focusing screen from old film cameras.

Split Screen with ZeroCross: will reverse the split direction whenever you achieve perfect focus.

Other parameters: size, position, magnification.

Notes:

• Zebras, focus peaking and false color are disabled automatically when the zoom overlay is active.

• Focus triggering only works with lenses that report Focus distance, or when you use follow focus / rack focus.

• In some modes, half-pressing the shutter may temporarily hide the zoom overlay.

Original implementation: Magic Circles by AJ.

Cropmarks

Cropmarks or custom grids for framing and composition.
