How dare you!

What do you mean "garry23 had to struggle in the very beginning".

I'm still bloody struggling 

@f.javi.pz

Too many questions in one go ;-)

Have a look at my latest script, DOFIS, for some ideas to help you.

Cheers

I've now added in a figure of merit feedback to give an appreciation of resolution loss as one focuses and stops down the aperture:

Not strictly DOFIS related, although this post uses the DOFIS model to give some rules of thumb to photographers seeking to get the most out of hyperfocal focusing: http://photography.grayheron.net/2020/10/the-hyperfocal-distance-understanding.html

I just tried editing as well, ie logged in OK.

Could edit, but not save.

I got this error message:

Security Token did not match. Possible CSRF attack.

Wanted to edit/clarify the ML DoF section.

I'm pleased to announce that DOFIS now fully supports the macro shooter: http://photography.grayheron.net/2020/10/dofis-now-for-macro-shooters.html

In case some are interested. https://blog.yifangu.com/2020/10/09/canon-eos-r5-thermal-mod/

Another short post for pano photographers.

Some background stuff to help with DOFIS, ie find the pupil magnification of a lens: http://photography.grayheron.net/2020/10/a-poor-mans-optical-bench.html

More fun with ML and DOFIS. This time perfect '3 degree of freedom' bracketing: exposure, focus and composition:

More insight for the photographers using DOFIS: http://photography.grayheron.net/2020/10/more-on-pano-pivot-point.html

Another little bit of the DOFIS story. This post with generic value to those seeking perfect panos.

@srsa

Thanks for the insight.

BTW I looked over on the CHDK site and now understand the limitations of Canon Basic.

I didn't make myself clear enough.

I was suggesting that maybe having access to Basic might 'satisfy' those of us that script, rather than waiting for a Lua implementation.

As I say, I was thinking out load and will now stop thinking 

Yes, I get that, but I have no idea of the time/effort to get a useful Basic scripting API up and running, vs a 'stable' full ML environment.

I was only thinking out loud.

I've been watching these developments with interest and much ignorance, but with high hopes.

What I think I see is a 'quick' way to get a scripting environment running, ie before, hopefully, we have a rich/full ML environment up and running, ie with menus etc.

Assuming, once again in ignorance, a Basic scripting API can access/control, ie set/get, key functions, eg shutter, aperture, ISO and, ideally, focus distance etc, such a scripting environment will be very handy for photographers.

I could imagine converting major parts of my DOFIS Lua script to a Basic script, ie giving focus DoF and focus bracketing feedback. Crude, but, I suggest, useful low hanging fruit.

But, as I say, I may be talking in ignorance of what is achievable via a Basic scripting feature.

'Finally', as promised, here is the latest version of DOFIS, that now uses an asymmetric, split lens model.

This latest version gives the correct field of views (horizontally, vertically and diagonally) as the lens changes focus, ie fully modelling lens breathing.

It also 'correctly' estimates DoFs from macro to the deep far field, although DOFIS only reports relative DoFs greater than a mm

For the pano photographers, DOFIS now estimates the position of the pano pivot point, ie relative to the sensor.

The latest post and info on DOFIS may be read here: http://photography.grayheron.net/2020/10/dofis-now-supports-macro-and-pano.html

In this post I cover the model for next major uplift to DOFIS, which will account for lens asymmetry, ie to cover the macro and pano photographers:

http://photography.grayheron.net/2020/09/dofis-start-of-major-update.html

This post shows how DOFIS helps with virtual Medium Format photography:

http://photography.grayheron.net/2020/09/dofis-and-pseudo-medium-format.html

I went to the open collective page, but it's not clear if we are 'active' yet.

I'm ready to support

A quick post for the photographers, especially those seeking to get more out of your post processing:

http://photography.grayheron.net/2020/09/dofis-dual-iso-16-bit-floating-point.html

This post should be of interest to those photographers seeking out a 32 bit based workflow, when undertaking deep focus and high DR capture, ie beyond what a single image can achieve, even with Dual-ISO 

http://photography.grayheron.net/2020/09/dofis-indoor-test-of-32-bit-focus-and.html

If you still don't see the oppurtunity

What!

Of course I do.

No more on this now.

Over and out.

@Danne

If you´re lucky maybe you get someone to do the dirty work for you

Just to be clear, I was never looking or expecting anyone to compile for me. I'm looking for a tutorial that lays out the steps on how I can compile, today, on a Win 10 PC.

Cheers

Garry

@Danne @names_are_hard

Fully understood.

Cheers, and stay away from the pestilence and stupidity
