PANASONIC DMC-G7

I made a curve for my camera, and i'd like to share it, but the forum says I can't upload attatchments. Can i email this to somone so they can upload it?

tex
That's odd

I haven't tried to do an attachment recently---maybe it has to do with recent security changes we've made.  I'll test it today.  You can email it to me if you wish, through the contact us link in the menu bar.

Thanks.  I will upload it and/or forward it to Masahiro.

Current situation camera profile and DCRAW support for DMC-G7

Hi there,

I am new here and for the first time I think of working with RAW files and also found this way my way to Lightzone, which looks a great tool.

 As far as I understand it looks like there is no camera profile for the G7 and that it is also not yet supported by DCRAW.

The first RAW picture from the G7 that I intended to work on has a terrible magenta cast in the edit window of Lightzone.

After searching the forum and the Internet in general, this seems to be a common issue and seems to be linked to the missing camera profile and/or DCRAW support.

Is that correct? If yes, anyone an idea when these issues might be solved?

Many thanks. Kind regards, Mike

dcraw

Panasonic DMC-G7 is on the dcraw's list of supported cameras, and it's RW2 files can be opened in LightZone, although without RAW Tone Curve. You can try to make one by yourself or wait for the one, made by dans79, become available. It might come with the next LZ version or even sooner.

Have a nice day!

Thanks a lot Jacal.

Thanks a lot Jacal.

I will wait for the update.

Nevertheless, I have created (with the help of Doug's tutorial) and saved my own raw tone curve and a raw colour adjustment as a "Style", but still I face the teribble magenta cast when opening the raw file in the editing window.

Doug
Magenta tint is dcraw

If you're getting magenta, dcraw is the problem, not the raw tone curve. Is it possible that you opened those Raw files in LightZone before updating dcraw? Try clearing the LightZone cache to clean out old conversions.

Mikey62
Doug, thank you.

Doug, thank you.

I 'll try your suggestions tonight.

Update:

Hi Doug,

it turned out my LZ version was outdated. After the update the issue was solved. I also uploaded the raw tone curve that I have created. Hopefully it oky for use.

Bye.

dans79, tex,

is the tone curve, dans79 has made, good enough to be linked here for testing?

(And, Mikey62, you could make your version available, why not?)

tex
I don't know, but...

The camera is on a list of 18 cameras Masahiro sent to me that I need to make RTC's for.  I hope to be starting that process tonight and through the next few days---new release coming (not sure what's in it, but hopefully these will be.)

Jacal
Thank you

and good luck, this is the real work to be done. Perhaps it would be easier in an Ottoman restaurant ...

Mikey62
Hi Jacal,

Hi Jacal,

I will also try to upload the raw tone curve that I have created, but I am not sure that it is good enough, as I am new to all of this.

Cheers.

 

Update:

the file has been uploaded to filebin: https://filebin.net/q8gp1m95zfo42cpa/Camera_Default_PANASONIC_DMC-G7.lzt

Hopefully it's good enough to use.

Does not seem good enough, I'm afraid

(Filebin looks to rename file names with spaces and semicolons, not a real problem, can be avoided by putting the *.lzt files to a .zip or .7z archive by yourself.)

I have tried your Raw Tone Curve (both versions, in fact) with two raw photos from Imaging Resource,

http://www.imaging-resource.com/PRODS/panasonic-g7/G7FAR2I0100.RW2.HTM

and

http://www.imaging-resource.com/PRODS/panasonic-g7/G7hVFAI00100.RW2.HTM

With your curve, images seem to look a little better than without it, but the colours are still way off, it might be worth waiting for the new version of LZ with updated dcraw.

Jacal
LightZone 4.1.6 now comes

with raw tone curve for this camera, but the City Hall image looks a little weird, with a teal-to-blue transition in the sky. Manually lowering the second from bottom locked zone (unstretching, if this is a word, the most stretched zone) in the raw tone curve, makes this particular photo look better. Perhaps this tone curve will need additional testing, possibly by users of this camera model.

In darktable and rawtherapee, the sky is blue.

Have a nice day!

I confirm the Jacal notice.

I confirm the Jacal notice.

And notice the "Raw Tone Curve" tool name doesn't have the "RAW" in capital which make LZ recognize it as a RAW Tone Curve like the XT-10's RTC I test this morning.

tex
Thanks for checking

I will take a look at it again and try changing it.  I'll also correct the title.

Mikey62
new RAW tone curve

Hi Jacal,

with the new version 4.1.6 I built a new file. The value of the different zones are only 1 off the ideal values. Perhaps this can serve now. Cheers

Switching from "RGB" to

Switching from "RGB" to "Luminosity" will fix the color problem, if my understanding is correct.

Photonoxx
I just test and it seems

I just test and it seems switch to luminosity mode fix the color problem for this photo at less.
