I have a problem with raw format of SD14 - Sigma in linux (Xubuntu 15.04). Do uou have plans to include foveon in your raw format camera collection?

Best regards

Sigma foveon Cameras

Hi

 

The Sigma Cameras are already supported. But there are problems as LightZone depends on the dcraw decoding library for RAW (They claim to support all the Sigmas). They have probems with their Colours (mostly red and green tint). We have few developer resources, so a solution is depending on the dcraw developers to find a way to make their Library working better with Foveon Sensors. I dont use a Sigma but this was what I could find about it. Is this your problem ??

 

A possible solution, might be to make your own Style (working with the tint of the three main colours). Lightzone is a RAW developer so it is a tool that can do it. If you then find a ballance between the colours that works most of the time, you can save it as a Style, and apply it all of your Pictures as a starting point for further adjustments. Another way is to save the Picture as a TIFF and then import it into LightZone.

 

Have a nice day

Hi,

Hi,

 

I'd love to support at least SD9/10/14 in LightZone v4.2. I've trying to create better colours from x3f these days, by modifiying both LZ and DCRaw's codes, but it is really difficult, especially DP series and SD15, SD1 and merrills.

 

 

As for current version 4.1, the best way to handle .x3f files is to export them into 16bit tiff with Sigma Photo Pro, and then open them with LightZone.

Sigma X3F processing alternative suggestion

Hello Masahiro,

You may have a look at the following by Roland Karlsson:

The problems you face are understandable. I appreciate your effort more for that!

Hello Sattva,

Hello Sattva,

Yes, I've once tried Kalpanika. I found it interesting, but I didn't have enough time to try it out. Thank you for the reminder. I'll look into it again.

Appreciate it!

Hello Masahiro,

Thank you once again for taking the time and the effort to work on implementing Sigma camera support in LZ!

To add to the conversation, i fully agree with your earlier suggestion that the best way at the moment is to process .X3F RAW files in Sigma Photo Pro and export as a .TIFF and then continue further with LZ. 

I have arrived at this workflow technique after quite a bit of experimentation with DCRaw. Which you may be aware is also capable of exporting linear gamma .TIFF files as Kalpanika...the linear output being my primary interest. BUT, what Sigma Photo Pro is capable of, no other software is able to...and inspite of the best efforts by some very intelligent and talented individuals, the inner workings of SPP remains a hit and miss affair...and a closely guarded secret by Sigma company!

So its SPP and LZ for me! And yes, i am happy :-)

Regards,

Sattva

Hopefully someday we'll be able to get Sigma to give us some support with their proprietary code so that we all can use other software  besides SPP to process their raw photograph formats. 

I too have an SD14, SD15, and a SD1m camera. They are great camera's with exceptional colour and resolution. I'm just peeved that I have to run SPP using Wine in Linux to get it to work for my needs 

as I don't subscribe to Windows whatsoever and their world monopolist views when it comes to software and intellectual rights to use such software. LightZone 4.1.0 works great on my Manjaro computer box and also on

another box that currently runs Fedora 21 which I will update here to F22 soon. Thanks for all of the hard work by the developers in making this software available for everyone to use.  It's a great program.

SPP 6.3 under Linux using Wine?

Hello Rich,

This is quite a late query to your post, still i am hopeful :-)

Did you get to make Sigma Photo Pro 6.3 work under Linux with Wine??

Any suggestions or pointers if you are indeed successful.

Regards,

Sattva

SPP 6.3 under Linux using Wine?

SPP 5.5.3 and earlier versions work in Linux 'Wine'. SPP 6.3 does not initialize. It installs but nothing works so far as I know.

Rich:)
