MUlti Shot Image Capture script

MUSIC
(MUlti Shot Image Capture)
MUSIC helps you quickly create bracket sets for various use cases, eg: noise reduction (NR); super resolution (SR);
people removal; ND simulation; Hand-held (HH) bracketing; FRSP and Zero Noise bracketing.
MUSIC works by taking the requested number of images according to the needs of the use case. Simply toggle through the various use cases until you find the one that fits your needs.
SR and HH use cases assume you are handholding to create the bracket set. Most other use cases will normally be triggered from a tripod (but it's your choice).
In NR mode, eg addressing high ISO shooting, your (photon) signal to noise increase will simply be sq-root(n), where n is the number of images you take.
Note, that if using NR mode to recover high ISO images, 4 would be a minimum and a sensible maximum number of images would be 16, giving a SNR increase of 4.
In some use cases MUSIC can exploit Full Res Silent Picture capture but you do need to respect some limitations:
- AF must be switched off in FRSP mode
- Shutter speed should be limited to between 0.3s to 15s (ML, not Canon, values)
- There will be 'time gaps' between FRSP frames, so if you can't tolerate these, then don't use FRSP mode
You can request the script to create a dark, bookend, image. This is useful in post to differentiate your bracket set. In FRSP mode, if your shutter is less than a second, the
bookend may not stand out well (but it is there).
Music only works in LV other than for HH bracketing, where you can enable triggering via the normal shutter, ie outside of LV, looking through the VF.
HH shuttered trigger does not have a bookend option.
HH ISO invariance limit should be set for your camera (change in UC1).
Note you don't need an AF lens or for AF to be on: in fact for FRSP AF must be off.
MUSIC has a Quick Access mode that allows you to retrigger the current use case by doing a long press of your selected QA button and time (change in UC1)
Canon review should be set to OFF. Switch ExpSim and Expo Override on - MUSIC handles switching these off and on, if required.
The usual caveat applies: the script was written for my workflow and enjoyment, and 'only' tested on a 5D3 and an EoSM with ML build Lua Fix (2020-12-28 18:15)
