General Help Q&A / Quick Shooting Screen
« on: February 11, 2021, 08:11:14 PM »
@a1ex

I'm in the process of adding a feature to my focus bracketing script (DOFIS) that will provide user feedback in the Quick Shooting screen (on my 5D3).

However, I've noticed a strangeness, that could be a 'ML bug'.

Here is a screen capture:

VRAM9q" border="0

As you can see, I'm adding a bar at the top that shows some focus info and changes colour according to focus overlap with the previously taken image. In the above the bar is white, but it can also be red or green.

All seems OK, however, as you can see the ML enhanced battery value has taken on the colour of my bar, and the battery colour changes according to my bar's colour.

None of the other ML enhanced info fields, eg colour temp, changes, just the battery field.

Just thought I would let you know.

Cheers

General Help Q&A / CBR Error
« on: February 09, 2021, 02:59:07 PM »
@a1ex

I get random console messages, ie not every time, saying "CBR Error not enough memory".

The script seems to keep running OK: 5D3 with latest Lua fix.

Without wishing to waste your time, have you any general guidance regarding this error message.

Cheers

Many thanks for the reassurance that there is nothing going ‘wrong’.

All

I’m embarrassed to admit that the focus info outside of LV missed me, reinforced by me continuing to read the old/current Lua documentation.

Agree with you about coders not being necessarily accountable for doc updates.

Not a straightforward thing to sort out when ML is a volunteer based community.

OK an update.

As Walter said, if I switch the Debug console request off, obviously I don't get the console.

But with the console on, I see the messages, which just look wrong to me.

I get these if no script or no modules are loaded.

Yes, I’ve tried multiple combinations and still get the messages above.

As I say, this started all of a sudden.

References to auto ETTR and intervalometer seem weird to me.

Yes, keep switching console off, but it always comes back on at start up.

@a1ex

I am more than willing to support updating words, as I have been doing on the wiki terminology piece.

The issue is, I don’t know what I don’t know  ;)

I’m embarrassed to say I hadn’t spotted the focus uplift.  >:(

I guess a point for the future is, that whenever code gets changed and uploaded to all, the code creator/changer should also look to changing any documentation. Easy to say, but not easy to impose.

All of a sudden the console always comes on at start up, ie something was triggering it: 5D3 latest Lua fix.

I have switched off all modules and still get this at start up, which confuses me:

image0w" border="0

Can anyone suggest what's going on?

I can't see how I have references to ETTR is I haven't loaded that module, and what's the intervalomter ref mean?

@a1ex

Just a few more thoughts on MLU.

The current ML MLU seems to ‘just’ switch the Canon MLU feature on or off on my 5D3.

This means that for my shutter triggered, hand held bracketing use case, this means I get a shutter-up, image shutter-down, then I enter LV and get a shutter-up, then script runs bracket capture, then exit LV for a mirror down. Works, and I’ve coded it as an option in my script.

As long as we can’t hijack the full shutter press, the above will have to do.

At the back of my mind is another weakness of the current ML-Canon set up: not being able to access focus info in non LV mode. The use case being using the VF and getting ML, ie a script, give you focus feedback.

Do you think it could be possible to remain in LV but do a mirror-down, so you can get the benefits of both modes, ie use the VF and keep getting focus info fed to Lua?

Just switching the camera on.

Tried several times.

Pulled the battery and retried: same.

Pulled battery and card with ML on, then restarted: ok.

Reinserted ML card seems ok now.

As I say, I don’t think I’ve ever had an error 70 message.

Fingers crossed all is ok now.

I posting this as I don't usually see Err 70 messages, but this occurred three times in a row, ie after pulling battery etc.

5D3 using latest Lua build.

Not sure if it's me causing it (eg one of my scripts) or core ML:

Scripting API suggestions / Potential Lua API additions
« on: February 07, 2021, 01:06:21 PM »
This is my humble attempt to start a list of user requested API ideas/enhancements/additions to Lua.

I suggest anyone posting here attempt to suggest their idea in a format that mirrors the ML Lua API documentation (see mine in this post).

I suggest this thread is not the place to debate the worth or even practicality of the API suggestion. Let's leave that for another place, once a Lua API 'uplift project' gets going. This thread is about ideas/needs/wants. Having said that, I suggest anyone posting here think about their need or use case, ie let's try and be sensible ;-)

The following are a few of my personal suggestions to get us going (note I have deliberately kept formatting simple, ie not complicating the posts with HTML:

----
lv.spotmeter(x,y[,width=10[,height=10]]])
  Returns the currently spotmeter value at the LV x and y position
  Only works in LiveView.
Parameters:
  - x int LV x position of centre of spotmeter box
  - y int LV y position of centre of spotmeter box
  - width/height int size of spotmeter’s width in LV units. Min = 5, Max = edge of LV_reached (x and y)
Returns:
  Requested spotmeter value, as set in the ML spotmeter menu, eg Ev units etc
----

----
lv.histo(x,y[,from=0)
  Returns the currently histogram % value between the requested x and y values
  Only works in LiveView.
Parameters:
  - x int histogram start (0,255)
  - y int histogram end (0,255)
  - from (0 or 1). 0 full LV, 1 from spotmeter box
Returns:
  Requested histogram % value
----

----
Camera.shutter.[class=raw].ettr
  Gets the current ETTR shutter value, according to the class selected
  Only works in LiveView, controlled by settings in ETTR menu
Parameters:
  - None
Returns:
  The shutter sub-class value according to the class used
----

----
lens.mf(value=0)
  Sets/gets manual focus, ie switches/overrides lens-set AF, ie MF on and off irrespective of lens physical setting
  Only works in LiveView
Parameters:
  - 1 = on, 0 = off
Returns:
  (bool) whether the operation was successful or not
----

----
camera.mlu(value=0)
  Sets/gets whether mirror is up or not
  Works outside of LV
Parameters:
  - 1 = up, 0 = down
Returns:
  MLU state
----

Thanks for the LV suggestion, I’ll look into that approach.

How about a new sticky link under scripting

Thumbs up for the FRSP vision  :)

My use case is when I’m handholding, eg super resolution bracketing or exposure bracketing, where I’m not in LV, ie using the VF.

But fully understand what you say and recognise ML priorities at the moment.

BTW I’m personally keeping a wish list of possible Lua API enhancements, I wonder if we should have a sticky link for capturing such API thoughts?

Scripting Q&A / MLU
« on: February 07, 2021, 10:09:45 AM »
@a1ex

I’m trying to understand how ML’s MLU work, eg on my 5D3, using the latest Lua fix build.

Seems to work ok in single shooting.

What I’m wondering is, would it be possible, from a Lua call, to enable it and activate it, ie move the mirror, then call shoot() as many times as needed, then switch off MLU, ie lower the mirror.

I appreciate this ‘request’ will need to be added to others and only enabled in the future when priorities allow. Just asking if you think it is possible.

In this post I discuss Use Case 6: MUSIC's (optimum) hand held, exposure bracketing feature:

https://photography.grayheron.net/2021/02/music-use-case-6-handheld-optimum.html

In addition, I discuss the new shutter-triggered option in UC6; that allows you to access UC6 from a normal shutter, ie using the VF.

UC6 gives you three exposures when hand holding:
1. An ETTR (base) exposure for the highlights, at the lowest ISO you can use
2. A second exposure taken at the slowest shutter you can use and the lowest ISO, ie to maximise the photon capture
3. A third image at the slowest shutter, but at the ISOless setting you have set in the MUSIC script, eg ISO 1600 on my 5D3.
