Hey dmilligan,
thanks a lot for your tip. I optimized the script now. It is working perfectly:

    else
        property.ISO.handler = nil
    end
end

config.create_from_menu(skipbadiso_menu)
skipbadiso_update(skipbadiso_menu.value)

The only thing which I am struggling with is the menu. I tryed it but so far I have no clue how this is working. By using my approach it is not relevant what arrow key is pressed on the camera, the menu selection every time selects the next value like in a circle. This is working fine, but it would be much nicer if I could use the arrow key to directly select the entry.

A little example:

   Off
> On
   Only 160s

If I want to select Off I have to press a key twice, because currently the state machine is: Off > On > Only 160s > Off > On > ... and so on.
It would be much nicer if I could use the arrow up key to directly select "Off". But I do not know how to implement this. Does this have to be a Submenu? Or could I also get it to work without a submenu?

Hi dmilligan
thank you for your tip regarding the many if statements. You are right, your approach would be much cleaner. As I am totally new to coding I have some questions:

I coded (but not tested) this:

1 Would this work this way ?
2 Can I definde my local variables (including the tables) in this way ?
3 Can I use "break" like I used it, or do I have to use "do break end" instead to skip the rest of the for statement ?
4 Can I access table values by using table_var_name ?
5 Can I get the table length by using #table_var_name ?
6 Do I use the for statement correctly ?
7 Do I need to initialize also the counter i as local via "local i" ?
8 Is there some way to test lua scripts on the PC ?


Here is only the relevant part the questions are for:

Code Select Expand


local old_value = camera.iso.raw
local new_value = camera.iso.raw
local ISO_step_up={77,77,85,85,93,93,101,109,117}   -- ISO values skipped to when increasing ISO
local ISO_to_skip={72,75,80,83,88,91,99, 107,115}   -- ISO values to skip
local ISO_step_dn={77,77,77,77,85,85,96, 104,112}   -- ISO values skipped to when decreasing ISO
local table_length=#ISO_to_skip
local i=1

function iso_mode_handler(self,value)
    old_value = new_value
    new_value = value

    for i = 1, table_length, 1 do
        if new_value == ISO_to_skip[i] then
            if old_value < new_value then camera.iso.raw = ISO_step_up[i] end -- ISO increasing
            if old_value > new_value then camera.iso.raw = ISO_step_dn[i] end  -- ISO decreasing
            break -- exit "for" statement
        end
    end

end


Many thanks in advance,
Chris

Hm, yes this may be possible. As I do not use video mode at all I do not have any experience there.
Currently, if I want to use ISO50 (never used it, but who knows) I first have to switch to ISO AUTO and then up to 50 as the switching levels are:

AUTO > L(50) > 160 > 320 > ...
... > 320 > 160 > AUTO


And here is the final version - tested on a Canon 6D 1.1.6. For a better robustness I changed the initialization of the local variables:

And by the way, sorry, I think this section of the forum is only for PicoC scripts. So if someone would be so kind and could move this thread in a LUA section? Thanks

@a1ex
Thank you very much for your tip regarding the LUA scripts. This was brilliant.
I managed to write such a script which skips unwanted ISO values in phot mode as well as in live view mode when set through the Canon ISO button + scroll wheel.

Do you think it would be better writing this in "PicoC" ? Would it be faster or less resource demanding? Is it even possible in PicoC to monitor for ISO changes like it is in LUA by using the handlers?

Best regards,
Chris

Here it is: http://www.magiclantern.fm/forum/index.php?topic=17110.0
...not bad for my first LUA scripting ever :-)

Currently I have only one problem:
When I am decreasing the ISO values I can not switch from ISO125 or ISO100 to ISO50. This does not work:

Code Select Expand


if (value == 72  and old_value > 72) then camera.iso.raw = 64 end -- ISO 100 gets ISO 50
if (value == 75  and old_value > 75) then camera.iso.raw = 64 end -- ISO 125 gets ISO 50


It always jumps to ISO 100. So I currently decided that I will switch into AUTO ISO instead. This works fine. Does someone have an idea why I can not jump into ISO50 mode?

Ok, this one works at least in the forward direction:

Now I have to save the previous values to be able to reduce the ISO levels again, once I increased them. Any ideas?

Hello together,
I am totally new to LUA scripting, but my goal is to write a script which is able to skip several ISO values when setting the ISO values via the canon scroll wheel (pressing ISO button + selecting ISO via scroll wheel). I started by trying to alter the copy2m.lua script. config.lua is also present in the script directory. Currently I have this code which does not run yet. I try to dig deeper. But I think currently I'm struggling with the handler concept. I do not know what the handler values can be and how I could find out this. Maybe someone could help me a little bit with this. my preferred way would also be to set the camera.iso.value istead of .raw, but I think the handler maybe in raw format. I don't know.
For the Canon 6D I read out the ISO RAW/VALUE/APEX data, which you could see below. When trying to read out property.ISO and property.ISO_AUTO it only displays "table: p" but I do not know how to look into the values of this table.

The idea behind:

When ISO is set to auto or any value not mentioned in the code above the camera will stay at this ISO value. But if the ISO is set to 100,125,200,250,400,500,1000,2000 or 4000 it will switch to another ISO value by it's own.

Is it possible via LUA script to change the ISO settings?

Ok, good. Please, can we leave the discussion about DR & noise for a moment. Fact is that there are no big gains or losses between ISO 100 & 160. But the shutter speed is better by using ISO160.

Yes I'm shooting RAW. But even with ETTR I get substantially less noise in the darker regions using ISO160. And beside all noise and DR discussions (which is always very subjective), ISO160 gives me simply a better shutter speed, which sometimes could be very important when shooting non stabilized lenses. So I really would like to have such a possibility to skip certain ISO settings when setting the ISO the Canon way. If this could be established be a LUA script I think this would also be fine for me. If it would be implemented into ML, even better.

Hi a1ex,
currently I use my Canon 6D exclusively for taking photos. And in 99% I'm not in LiveView for that. And I change my ISO not from the ML menu but directly by pushing the ISO button and selecting the ISO value by the scroll wheel.
Maybe I can try the LUA script approach. Do you think this one will work? I think about something like:

- read out the current ISO setting whenever the ISO is changed
- if the new ISO is an unwanted ISO, set the next higher ISO step

Currently I am totally unexperienced in LUA scripting. But I think this one is the right reference to look at: http://davidmilligan.github.io/ml-lua/
Or are there other, better, references to start with?

...will wait for that until the lua_fix is merged.

My suggestion:
A possibility to deselect the ISO levels one do not want to use.
e.g. on a 6D with 1/3 ISO steps the ISO sequence when setting via the ISO button on the camera is:
100  > 125 > 160 > 200 > 250 > 320 > 400 > 500 > 640 > 800 > ...

Now it would be nice to have a possibility to deselect some ISO levels. e.g.:
125 / 250 / 400 / 500 / 640, so the new ISO sequence when setting via the ISO button on the camera is:

100 > 160 > 200 > 320 > 800 > ...

Would this be possible?

I'm currently struggling getting the RAW Histogram to work.

Cam Settings:
- Image Quality: RAW only
- Image review: Hold
- ML Histogram Settings: RAW-based (RGB), ETTR hint, Log scaling, Clip warning

Now there are three scenarios:

1) Live View
Here the RAW Histogram works

2) View recorded images (Play Button)
Here the histogram is not a RAW histogram. It is based on the JPG preview and the Picture Style settings

3) Quick Image Review after taking a picture
Here I would expect that the same result as in LiveView is displayed. But this is not the case. This also seems not to be a RAW histogram. It is even worse. It seems like I'm getting a clipping warning way earlier, even before the JPG image goes into clipping. So e.g. I get a clipping warning in the QuickReview after taking the picture, and when I then hit the play button to view the picture the histogram has plenty of room to the right?!

I would have expected that at leat scenario 1 and 3 would show the exact same result, so that it would be possible to judge the RAW histogram without going into live view every time. If scenario 2 is also capable of displaying RAW data, I don't know. But as I have said, at least in the QuickReview I would like to see the real RAW histogram.

Any suggestions?

Best regards,
Chris

Good evening,
is it possible with ML to setup the 6D, so that only ISO 160/320/640/1250/... can be activated by the ISO button? Like the 1-stop feature in the original firmware but instead of switching from 100 -> 200 -> 400 -> 800 -> ... the Canon 6D would switch in the order 160 -> 320 -> 640 - ... ??

Best regards,
Chris

Ok, I read a lot about ML and the Canon 6D with V1.1.6 . Now I really want to test it ...BUT... one thing remains: Until now I couldn't find a final answer to the following two questions:

1) Is it possible to disable the bootflag of the Canon 6D once it has been enabled - and if yes, how?
2) Is it possible for Canon or anyone else to detect if ML was installed in the past after disablind the bootflag again? So, is every single bit of the cam firmware set to the original value once the bootflag is disabled again - or are there also other changes to the original firmware/memory of the cam?

Many thanks in advance,
Chris
