New Mac Download Packages Available, And Also Linux And Now Also Windows

Posting rules: It shouldn't need saying, but... play nice. Please keep your discussions civil. You can disagree, just don't be disagreeable. And, of course, all of the usual stuff like no spamming. Tex adds: I'll be rigorously enforcing this as we go along. We're probably going to be a small community in a little lifeboat, so we can't have members at each others' throats. This is for the sake of the project as a whole. So when you post, pretend you're speaking in person with your very wealthy auntie who has always treated you wonderfully and currently lists you prominently in her will. I won't be tossing anyone out of the forums because we are all in this together (except spammers: immediate membership cancelation), but I'll delete suspect posts right away.

Masahiro has developed new Mac download packages that have fixed some problems users experienced.  Changelog is here . He has prepared Linux packages as well, but has had a little trouble with Windows this time.  Now Sorted!  Thanks also to Ron Goldthwaite for testing and finding some errors.  Nice to see you back, Ron!

Note for Ubuntu 16.04

I haven't update packages on LaunchPad PPA. Sorry about that, but please wait until this Friday. I'll post an anouncement here when I update the packages.



PPA packages are now
Limux Mint

Works great, however it needs libjpeg62:i386 in 64 bit.
I dont know if you can add an automatic dependency for the apt-get process

TZ100 support

Thanks for the update and adding support for the Panasonic TZ-100. Unfortunately, at least with my TZ-100, the raw tone curve is giving some posterization. I will try to find time to set a new 'camera default' RTC to see if I can get a better result.  

Great, great, great :-)

Great, great, great :-)

It starts with 10.6.8, it works so far with 10-6.8 and the preferences dialog seems to work again :-)

Thank You!!! :-)

4.1.7 Now also available for Windows

Tex could you add a post to make it clear that a Windows version of 4.1.7 is now also available - the websites main page still gives the impression that there are outstanding issues (you have to read the comments to see that the Windows version has in fact been released).

Yes, and thanks

for the reminder

Problem with dropdown menus in Snowleopard

While LZ 4.1.7 works really well on Snowleopard (10.6.5) I otherwise encountered a problem opening the dropdown menus i.e. "Blending Mode" in the Tool Stacks or the dropdown to choose aspect ratios for the Crop Tool. The dropdown menus won’t stay open – the menu is visible for a fraction of a second. Blending modes are still selectable via scroll-wheel, not so aspect ratios… this is reproducible in LZ 4.1.7 and 4.1.6.

The very title of this topic

now reflects the harsh, step by step, one OS after another, development of this version. Thanks to Masahiro, and also tex and also everybody else.

Colour space and printer profiles

Hi. I'm using 4.1.7 on Sierra and noticed that the choice of colour space profile for saving is only srgb now. Also the soft proofing is not picking up any printer profiles. I checked with version 4.1.5 and it picks up all the profiles.


This might not be the best place

for your question (and I, by the way, can't reproduce the problem neither on Windows or Linux), make a new thread under "General discussion".

Rob A
OK I'll do that, thanks.

OK I'll do that, thanks.

Hi, Does the new release still have a requirement on Java 6?

4.1.7 not launching

First of all, thank you so much for all the work you do to make this available to all of us!

It seems doing the Windows 10 Anniversary update broke my lightzone 4.1.7. I uninstalled and reinstalled on my Surface Pro 3 but it just refuses to launch.

Would appreciate any thoughts on what could be happening.

Thanks in advance!

LZ 4.1.7 on 10.6.8

Works nice and quickly, nice GUI,  but there´s a bug who doesn´t let me change the preferences in the boxes with a arrow.

It´s a pitty, so I can´t export my RAWs to TIFF.

Thanks to all for your work here!


Hi Sir you have a great software and I am glad I had the chance to experiment it. the only complaint is the your website is very dificult to read. too much on display. if I were you I would built more pages intead. For instance a single download page where people go just to download and a different coment page.
