Panasonic TZ100

Just started using Lightzone again (last used in 2008). Any possibility that a raw tone curve for my Panasonic TZ100 can be added for the next build?

Hi.

Hi.

 

I don't know if it's already planned, but you could try to make your own RTC using the video tutorial available here :

Welcome back!

Yes, you could do that yourself, but let me look into it also.  I'm going to be doing some more profiles shortly for the next minor iteration, and maybe I can throw this one in (but understand we have to rely on both dcRaw AND Imaging Resource test images in order to produce the raw profiles...)

RTC for TZ100

Thanks Photonoxx and Tex.

On starting to create the RTC it was clear that the RAW conversion was not correct for colour and had significant distortion. I think that as I'm using a Mac I have downloaded v4.1.5 as there are problems mentioned with v4.1.6. This probably does not have the latest version of DCRAW that includes the TZ100 (or ZS100) which would probably account for the colour problems. It works fine with my Olympus E-1 and E-620.

The distortion may be a problem if Lightzone does not take the information from the camera to correct the inherent lens distortion which is really quite significant. 

I created the RTC anyway just to check the process but it will need to be redone.

The lens correction not yet

The lens correction not yet available in Lightzone but it should come, so it's normal you still get the distortion.

Alternatively, you can work on your picture in Lightzone and when you finish, use another software to correct this. It's what I use when I need to correct perspectives (hopefully, my lens does'nt have noticeable distortion), but you need to be carefull if you use crop rotate in LZ probably as distortion correction may be miscalculated.

The distortion on the TZ100,

The distortion on the TZ100, at least at the wide end of the range, is such that it would make editing the image difficult. It's one of the compromises with a compact camera and the manufacturer relies on the software correction to get acceptable results. For now I'll probably do RAW conversion in another program with automatic lens correction and transfer to Lightzone as a 16 bit TIFF (or linear DNG?) if I need Lightzone specific adjustments.

My dslr lens have very low distortion so I can use Lightzone directly for them.
