Have you explored a Lua script?

@Mefist

Are you seeking to bracket just macro shots or landscape shots?

The ML focus bracketing covers macro, my focus bar and other scripts have been written cover landscape focus stacking needs.

Two separate and radically different use cases.

Raw Video Postprocessing / Re: Debayer without interpolation?
« on: July 18, 2018, 06:29:16 PM »
Just to add another perspective to @Danne.

I wrote a script to auto create a set of images for super resolution processing: http://photography.grayheron.net/2016/12/a-new-technique-for-super-resolution.html

My approach was to be on a tripod and use refocusing to generate the frame to frame differences. You could simply IS jiggle, refocus or do both at each image.

Had some fun for a while but didn’t develop the technique further.

Focal length  ;)

Be careful if going ‘very’ wide.

There is also this post to read : https://www.magiclantern.fm/forum/index.php?topic=21602.0

Plus remember dual ISO comes with a little cost, As a1ex says:

General Help Q&A / EOSM Auto Bracketing ‘light’
« on: June 10, 2018, 02:20:53 PM »
When use auto bracketing the self timer lamp on the front and the power lamp on the back of the camera light up and stay on when taking images.

Is there a way, through ML, to switch these two lights off?

The problem is, when shooting through glass, you risk getting the front lamp as a reflection. Also if taking single images the power light stays on and I am seeing a ‘colour cast’ in my IR converted camera and am hypothesising the power lamp might be the cause, ie internal reflections.

Postscript

Having spoken to the guy who did my EOSM conversion, to 720nm, it looks like the EOSM sensor has an asymmetry that results in colour cast down the left hand side.

Apparently the EOSM3 has this as well. Not sure why? Tolerancing in the glass maybe? You see less of the effect if you convert to a full spectrum filter, ie less glass.

If you process in B&W you won’t see it.

If you process in false colours you will, especially if you push the colours, eg with a heavy debase.

You can reduce/eliminate the colour cast in LR, but it will require a bit of extra post processing.

Just a warning if you are thinking of using an EOSM for IR imaging.

Cheers

@arch80

Intrigued. Why have a 5D3 and 'limit' your photography to medium RAW?

@Kanakori

Video, helped by ML, should be easy. In fact a non-ML video should also work.

'All' you need is an IR converted camera and some channel swapping.

Pick up a cheap EOSM and get it converted  ;)

I personally don't do video.

Cheers

For those that like 'playing around' in the IR bands: I've just posted about ML-enhanced IR photography at: http://photography.grayheron.net/2018/05/infrared-post-processing-in-lightroom.html

As a flavour: here is one of the handheld images I took today with my trusty IR-converted EOSM:

My twopenth, as a stills photographer, is follow @a1ex’s advice, unless, you need the F/8 focus ability, as I do with my x2 extender on my 70-200 F/4L.

The 1.2.3 works with all my Lua scripts  :)

Thanks for the insight.

I’ll work around things ;-)

@a1ex

Had a look at 'disabling' the setting but no luck.

Had a look at things via GUI events and I attach the screen dump; after I switched off all my scripts.

The last two lines are associated with the right button on the EOSM.

As you can see, the JOY_Centre button, which I pushed previously, seems to be picked up, ie 11. But I don't know what all the numbers mean.

General Help Q&A / Re: ETTR and Auto Bracketing
« on: May 24, 2018, 07:27:59 AM »
The reason for the original post was that I didn't want to trigger ETTR via the SET, which does allow me to access AB as well.

I've now decided to work around this, i.e. use SET to trigger ETTR.

Scripting Q&A / EOSM RIGHT/LEFT Keys
« on: May 23, 2018, 11:59:39 PM »
Have just noticed a strangeness on my EOSMs.

I've been looking at keys, ie the number returned.

UP, DOWN and LEFT return the expected number.

RIGHT does not return a key value to Lua.

On the EOSM the right key is used to toggle between exposure and aperture. I wonder if this Canon 'control' overrides the Lua side and thus the right key is not accessible in Lua?

Can anyone, eg @a1ex, throw some light on this strangeness?

General Help Q&A / ETTR and Auto Bracketing
« on: May 23, 2018, 08:38:37 PM »
@a1ex

I wonder if it would be possible for you to make ETTR and Auto Bracketing work together a little better.

My use case is simple. I always have ETTR on via half double press. But if Auto Bracketing is on I can’t access ETTR.

What I ideally would like is to have both ETTR and AB active, with ETTR active from the half double press and AB being triggered via, say, a full press.

What do you think?

Cheers

Scripting Corner / Only to be read by EOSM Photographers ;-)
« on: May 12, 2018, 04:15:31 PM »
If you have an EOSM you may be interested in my latest blog at http://photography.grayheron.net/2018/05/eosm-script-set.html

These four scripts have been tuned for the EOSM, ie with its limited buttons but an active screen.

The scripts are:
- 1m is a Toggler, that allows you to control access to the other scripts and core ML functions such as ETTR, Dual-ISO and Auto-Bracketing;
- 2m is the Focus Bar;
- 3m is a Hand Held Helper script;
- 4m is a ND Helper script.

As I have written about these on past posts, I won't regurgitate how to use them here.

@50mm1200s

I have looked at bracketing, however, with my IR converted EOSM, I find I don't need to bracket.

The reason I like having my IR camera with me is the fact the 'best' time to shoot is in the middle of the day and I usually find there is enough IR light for a single capture.

Cheers

In case there are any ML based IR photographers out there, I thought you might like a read of the last two posts on my blog: here is the second one http://photography.grayheron.net/2018/05/tent-rocks-in-infrared.html

First, ML is a great aid in IR photography, eg ETTR and my IR sensitive Focus Bar script; and second the latest release of LR allows you to carry out channel swapping via a LUT based profile, without having to go to Photoshop.

@dmilligan

This isn’t the exact script, but it’s 99% close: https://gist.github.com/pigeonhill/cd1dbe0191ca1264fc0aa07aaafb515d

BTW one project I have is to rewrite this script, as my coding is a little better now;-)

@dmilligan

I reminded myself of the education you gave me here: https://www.magiclantern.fm/forum/index.php?topic=16677.msg162535#msg162535

You also hinted at a few ideas:

Quote
There are a couple of things I might could do with the backend that might help some of this:
1. More info about the semaphore timeout (like what CBR it was that was trying to execute, and what was blocking it)
2. Long running API calls (like camera.shoot) should "give" the semaphore while they are executing.


Bottom line: I will have another look at my code to see if I can minimise the semaphore timeouts, but I also will stop 'worrying' about them ;-)

Cheers

Scripting Corner / Re: Semaphore message
« on: April 26, 2018, 02:20:27 PM »
I appreciate my previous post is rather unstructured.

The bottom line is: how could I narrow down the part of my script, and when, that is generating the semaphore message; when I don't have QEMU?

Cheers

« on: April 25, 2018, 06:52:57 PM »
I hope someone can point me in the right direction, as I can't work out why I'm getting these messages; as they don't appear to stop my script running.

I’m running the latest Lua experimental version on my EOS(M).

Cheers
