crop_rec and derived builds / Mmmm, this code tasts yummy
« on: January 28, 2021, 02:36:26 AM »
As you may or may not be aware, "official" ML development has slowed significantly in recent times (background reading).

There have been contributors to the project who have continued to develop in their free time, and this section is dedicated to those contributors who develop and release builds.

Three core considerations when using this section.

They may work perfectly fine, they may melt your camera in half. They may appear to work, until you develop the footage and discover you just wasted an entire day. The onus of responsibility lies solely with you if you decide to use these builds. Don't use these builds in any sort of professional capacity unless you are sure of your workflow.

  • The usual caveats apply. If your camera breaks in two because of the code given freely here, you get to keep both pieces of your broken camera.

Other experimental builds / Latest Lua updates + fixes
« on: January 28, 2021, 02:15:08 AM »
Latest Lua updates (details).

Includes many other backend changes, e.g. focus, menu, Q button handling, fonts etc.

Therefore, it's important to give it a good try on all functions, not just Lua, so we can include it in the nightly builds.

Also includes lens.focus_pos and dynamic-my-menu.

Other experimental builds / Non-CPU lens info
« on: January 28, 2021, 01:50:51 AM »
Set lens name, focal length and aperture for manual lenses. Lua script.

Download / Source code / Technical discussion

If we can assign lens focal length and name for non cpu lenses, ( like using nikon lenses on a canon with an adapter) then I can use this data in post processing to identify what lens was used and which lens profile I should apply for distortion correction.

Other experimental builds / Pre-recording with half-shutter triggers
« on: January 28, 2021, 01:47:54 AM »
Should work on top of latest nightly build.

Download / Source code / Technical discussion

I was trying to film dogs catching Frizbee the other day, and was thinking, I wonder if there's a way to add a buffer record to Raw_Rec module, like have it record to buffer but not to file for the certain amount of frames the user chooses as a buffer, then when the action you want happens, you press the shutter and it records the buffer to video file?

Other experimental builds / ISO experiments (iso-research)
« on: January 28, 2021, 01:38:13 AM »
Experimental builds based on CMOS/ADTG/Digic register investigation on ISO.

Just a small improvement in dynamic range in photo mode (around 0.3...0.5 0.8 stops). We were able to fine-tune the amplifier gains in order to squeeze a little more highlight detail.

Download / Source code

Feel free to discuss build related issues in this thread, and if you would like to contribute with some more technical related things, the original thread is probably best suited.






Some other experimental work is done by timbytheriver, Cleaner ISO presets.

Scripting Q&A / Take a photo at each ISO
« on: September 27, 2018, 02:49:42 PM »
Code: [Select]
function test()
    camera.iso.apex = 5
    camera.shoot()
    camera.iso.apex = 6
    camera.shoot()
    camera.iso.apex = 7
    camera.shoot()
    camera.iso.apex = 8
    camera.shoot()
    camera.iso.apex = 9
    camera.shoot()
    camera.iso.apex = 10
    camera.shoot()
    camera.iso.apex = 11
    camera.shoot()
    camera.iso.apex = 12
    camera.shoot()
end

keymenu = menu.new
{
    name = "ISO photo bracket",
    select = function(this) task.create(test) end,
}


I found the apex values by running this script.  Is there some documentation somewhere that explains apex and raw values?

Forum and Website / Dropbox changing public folder to private
« on: March 10, 2017, 01:44:08 PM »
This means all previously linked images in public folders will now be dead.  I'm pretty sure most of my content on this site is from my public folder.
Feel free to pm if you're reading content and need the image links updated in my posts, and I'll find the time to do so.

Scripting Q&A / LUA resources
« on: January 26, 2016, 02:38:17 AM »
Sticking this here as a reminder.  Feel free to throw info at this thread and I'll make it look pretty as time permits.


Quote from: Original Post
There are also countless programming resources online. You might consider learning some basics in an easier environment, something with a nice IDE, syntax highlighting, debugger, auto-complete, etc.

Do you or others have some suggestions?

I'll try and compile a useful sticky thread, and suggest to the powers that be that we retire everything picoC related and relegate Scrips Writing to LUA.

Camera-specific Development / Canon 60D
« on: March 16, 2015, 04:49:49 AM »
Installation:
1) Format the card from the camera.
2) Make sure you are running Canon firmware 1.1.1.
3) Copy ML files on the card and run Firmware Update.

Uninstallation:
1) Run Firmware Update from your ML card.
2) Follow the instructions.





Discussion thread for the 60D.  I don't own this camera, so if there is anything you feel is important for this camera and should be in this opening post, please let me know.

General Help Q&A / Stable build | Latest builds
« on: January 11, 2015, 12:51:28 AM »
The very old "stable" build of Magic Lantern has been removed.  That build of Magic Lantern was over two years old and still contained bugs that were missed during testing at the time.

Magic Lantern now works on a rolling release development model.  The nightly builds can be considered somewhat stable.  The features in the nightly build have been well tested, with untested development moved to an branching system for testing before being included in the nightly builds.

Some of the features that have been developed since the "stable" version. Thanks dmilligan

General Chat / XISF Version 1.0 Specification
« on: December 22, 2014, 03:00:31 PM »
http://pixinsight.com/doc/docs/XISF-1.0-spec/XISF-1.0-spec.html

Quote
Extensible Image Serialization Format (XISF) is a free file format for storage, management and interchange of digital images and associated data.

XISF has been originally designed and implemented as the native file format of PixInsight, an image processing software platform designed specifically for astronomical imaging, and developed by the company Pleiades Astrophoto S.L. However, our hope is that XISF serves as an efficient tool for the development of imaging software, including not only software specialized in astronomy, but image processing software in a wide range of technical and general fields.

Two key elements in the design of XISF can be found in its title: extensible and serialization. Extensibility is crucial to adapt the format easily and efficiently to the requirements of present and future software applications. The architecture of XISF has to facilitate the development of extensions to the core format specification, and for this purpose XISF headers are standard XML documents. Serialization denotes the ability of XISF to store not just image data, but also data structures associated with the environments where the images evolve as living objects. These data structures can be deserialized to recreate the images along with their working contexts. We formalize the resources to store data structures and objects as properties of a variety of predefined data types. XISF properties can be directly associated with images, with entire XISF units, or be defined as standalone components.

Finally, XISF is a free format open to the contributions of anyone interested, including users of PixInsight and other applications, as well as individuals and groups from other development teams, institutions and companies involved or interested in image processing software.

Forum and Website / How to use the forum search feature
« on: October 20, 2014, 03:59:21 PM »
Using the options below, you should be able to narrow your search results down to useful results, without having to wade through a bunch of irrelevant search results.





The blue circled search box is a thread search.  When inside a thread, you can use this box to search for words inside that thread.
The red circled search word is the main search function.  This is a dumb search.  Enter a word here, hit search, and it will list all posts containing that word.
The green circled Advanced search is where the real power lies.  See  below.





This advanced section, opens up some more useful search features.
You can search for words by a user, simply enter the forum username.
Define the search order.
Search in the topic subjects only.  ie:  Thread titles.
Define the age of the posts to search.  ie:  Only search for the word in posts not older then 3 days (or 5 days, or whatever you define).
The red underlined option also allows you to define which sections of the forum to search.  See below.

General Chat / Lens effects on photons
« on: October 15, 2014, 11:51:11 PM »
Topic split from http://www.magiclantern.fm/forum/index.php?topic=10111.msg131472#msg131472



In the first graph, you can see the 5D3 and the 60D are just as good. That is, if you would use a 80mm/2.8 lens on 5D3 and a 50mm/1.8 on 60D, you would get the same results (same framing, same low-light performance at high ISOs).

I know you used these lens as example, but you must also consider lens diameter.  That is, two 300mm/2.8 lenses with one having a diameter of 50mm, and the other having a diameter of 100mm, the larger lens will let through four times the light.
Rodger Clarke makes small mention of that here.

I believe that DxO measures ISO without a lens attached, so I only mention the above for completeness.

Pixel pitch seems to play some role also.
