Is LightZone Dead, Again?

Looks like there hasn't been an update in quite awhile and I don't see much, if any, new activity posted on the main page of this website so... Is LZ dead, again? I vaguely remember reading on this site some time ago that new functionality was planned. Is new development in the works? Anybody have any idea when we'll see a new "meaty" update?

Thanks!

No It's Not

The latest work on the project was april 15th, 2017, see the bottom of the Github website here --> https://github.com/ktgw0316/LightZone/compare/4.1.7...master by ktgw0316 AKA  Masahiro

 

Looking through the list, you can see the DCRaw was updated on May 14th, 2016 to the current version of 9.27.  My guess is that no further release to LZ will happen until DCRaw is updated to 9.28, whenever that happens.  Dcraw is the standard tool in many open source projects today.  Often they include new raw profile from new cameras not released in the old versions.

 

I forgot to point out the latest relase was actually 4.1.7 in 9/25/2017 (correction 9/25/2016), see --> https://github.com/ktgw0316/LightZone/releases/tag/4.1.7

Date Correction

I think you meant 2016 not 2017

Thanks Den!

I corrected in my post.

Not dead

The development is for periods of time quite slow. This is because we for a long time just have one developer. So development will be when he has time to do so. And life is thankfully giveng other things to do than programming. But there is updates and enhancements on ther way. If anyone can help with programming, translation or tutorials, it will be most welcome.

But having more activity here (and most of it positive, welcomming and friendly) on the site will for sure be very velcome. It could be about to achieve some effect or correction with LZ. How you are using the program. And sometimes just a showoff of what you have done. Unfortunately the site does not support pictures. Maybe a bit of ar paradox for a photosite.

 

Have a nice day

LZ Undead

Please allow me to stress that I'm not critizing...rather curious as to what may be happening and what we might see "down the road." I was a very early adopter of LZ and, though I don't use it as my primary editing tool, there is functionality in LZ (llike the Relight tool, for example) that I find extremely useful on some images. Therefore, I still turn to LZ for some projects and would certainly welcome new functionality; that is, new tools.

Steve - the last release on 9/25/2016 is nearly 7 months ago. In digital terms that's approaching eon territory! Just kidding, of course. I, also, know that releases of LZ can be tied to a new release of DCRaw, but updating of DCRaw to include new cameras, etc, is not IMO an update to LZ. I'm sure many current LZ users would like to see some new tools added...maybe, it's just me. ;)

larshenrikoern - Wow...sorry to hear there's only one programmer left...bummer! That would certainly slow things down!! I'm curious...given the meteoric rise in LZ interest back when this site first got some steam behind it, do you think interest has significantly dropped off and nobody really cares if LZ gets any new functionality?

A kitschy postcard

from a location near my cabin in the woods, where I have been lately spending most of my time. To add a photo to this forum.

https://app.box.com/s/jhvwrcch11bl5h0kvv1ubm5z014778qi

Three quick handheld shots (the strong wind was very cold, it was -10 degrees Celsius), developed to 16-bit tiffs with RawTherapee, merged with Hugin, finalised using LightZone.

Everything besides the sky should be white early in March, but because of the lack of the snow, the colours are a kind of weird. The grass and the broadleaf trees were not starting to become green yet. The sky looks over-edited, but so did the "reality" look to my eyes, Zeus has made it overly dramatic.

Our developer would certainly need some coworkers, but this is easy to say. By the way, did anyone recently build LZ from the master branch? It should contain some good improvements already. I might try, but I might not be competent enough for this. We'll see.

Re: A kitschy postcard

A nice shot nonetheless IMO! And, wherever your cabin in the woods is...I want one!! :) :)

Alan, Ah, the digital Age

The digital age is great but I come from the days where I would submit a job (card deck) to the IBM 360 mainframe and have to look at the queue and wait from my job to slowly work it's way up the chain to completion.  There was no instantaneous results like today.  Patience was truly a virtue.  Perhaps we need to have similar thoughts with the progress of LZ seeing how shorthanded the project is.  I wish I could help but do not possess the necessary skills to do so.

Re: Alan, Ah, the digital Age

sfink16,

I started my IT career back in the IBM 360 days. Job queue? We didn't have no stinkin' queue! ;) You read the card deck in, partitioned memory, fired up a job initiator, and prayed your job didn't abend with a SOC4 or SOC7. Heck, we still had many master files on paper tape! Hard to believe that nowadays I have more computing power in my pocket...and it can make phone calls. :)

Hi Jacal

Nice to a picture. Nice and big. First I thougt about if ligtzone could combine pictures. Never heard of that. Then I read on and could see you are using hugin. And that explains a lot. Why arent you using LZ to make the TIFFS ??

 

Hi Alan ?

There is some interest for sure. Otherwise nobody would answer your kind request. But the main problem is lack of programmers. They are ther people thath makes things happen. But there might be something on its way. Masahiro has recently begun to add support for Visual Studio. This might make it much more easy for new developers. And these might already be at hand.

 

Sfink

I completely agree with you. For me LZ can do what i need (and a lot more). That is what matters for me. And then there is the fun of talking and helping other users.

 

Have a nice day

larshenrikoern,

I have used RawTherapee for lens distortion and vignetting correction, which, in this case, wasn't really urgent. With neutral profile plus default colour noise reduction, nothing else. Quite dull images for a start.

 

Be well!

larshenrikoern
Lens distortion

Hi Jacal

 

Yes off course for correcting lens distortion. Correction for this is by the way still being developed for LZ. The backend library, which RawTherapee also uses, is lensfun, which by the way is calibrating for distortion using hugin. So someday you could as well use LZ for the task.

 

Have a nice day

You sure that RawTherapee

You sure that RawTherapee uses lensfun for lens correction?

Jacal
It does not,

it uses Adobe's lcp profiles.

Darktable, digiKam, ufraw/nufraw ... are using lensfun.

Trickortreat
Anyway, I find that

Anyway, I find that RawTherapee's lens correction module is far more versatile than lensfun because it can easily correct even those lenses that are not included in the library. That includes old manual prime lenses (that i use really much on my Pentax) and new lens releases which thake more than a year to get incuded (some even don't get included at all)..

larshenrikoern
If you misses a lens you can help Lensfun

Hi

 

If your lenses are not supported, You can help lensfun be taking a few pictures of a brickwall or something with straight vertical and horizontal lines, and sending it to their calibration service. Look here: http://lensfun.sourceforge.net/calibration/

Lensfun is opensource and depending on your and other contributing. Its fun and quite easy. You are helping yourself as well as others. Torsten Bronger who are the maintainer is friendly and helpfull.

 

And by the way. The tool that someday hopefully will be included in LZ will also contain manuel correction, so you can do it yourself. And then also bringing the creative tool for distorting an image.

 

Have a nice day

Jacal
I agree,

not because lensfun is actually doing better work with my Sigma lens on a Canon camera than the Adobe's sollution. Community-built software might be worth supporting for reasons, unrelated to our photography related needs. At least I like the idea.

Trickortreat
Oh.. nice. That's the part of

Oh.. nice. That's the part of lensfun implementation in Darktable i found lacking. I like manual correction because it's hard to correct some lenses via automated means.

Also, as you said - distorsion and lens flaws are not always a bad thing...

Sorry for the late reply.

Sorry for the late reply. LightZone is alive, and I've been working on the lens corrections and a film grain emulation feautures. Source code is available from my "distortion" repository so you can build and try it on Linux if you interested in it, though it is still an unstable draft version. Specifications may change without notice in future release.

 

I enjoy coding and learning a lot of things through this project, but my free time is limited these days. Thank you for your patience.

We know, we know

Thank you Masahiro.

 

I am my self with small kids. They and my wife is the most important in life. So that you are capable of managing doing something more than that and your work is great. I look much forward to the new features.

 

Have a nice day
