Vignetting effect on RAW file with Panasonic Lumix TZ70

[Theon]

When importing RAW files from my Panasonic ZS70, there is a vignetting effect which makes the RAW image useless to edit.

I do understand this camera is not supported.  Though, it is an incredibly popular camera and I'm frankly surprised by this of a company of your size.

Is there any way around this problem or any word when this camera's RAW image import might become usable in Affinity?

 

Thanks.

What Operating System are you using?

Which Camera do you have? the TZ70 or the ZS70

You could use Adobe Raw Converter to convert the RAW file into a Raw DNG file

Thanks for the response, Firstdefence.

I'm on a Mac High Sierra 10.13.6 and the camera is the ZS70.

Thanks for the Adobe Raw Converter tip.  I am unfamiliar with DNG files. Some questions:  Are they the same quality as a RAW file? If I convert them, I'm assuming Affinity will have no trouble reading them? 

Thanks, again.

I had the same problem. Affinity uses Lensfun for lens correction (the same library/database as darktable uses). The problem is that this model was introduced on 3 different model names: TZ71 in Germany, TZ70 in rest of Europe and ZS50 in North America, while TZ60/TZ61/ZS40 also have the same lens, but in Lensfun only TZ71 and TZ61 are associated to this profile, so with other model names autodetection won't work.

I know that this question is old, but I copy the solution for it, if anybody else still have the same issue:

You have to find the Lens Profiles folder, in Windows it's c:\Program Files\Affinity\Photo\Resources\Lens Profiles\ with the basic installation. In this file add the following to the list of camera profiles:

    <camera>
        <maker>Panasonic</maker>
        <model>DMC-TZ70</model>
        <mount>panasonicTZ71</mount>
        <cropfactor>5.58</cropfactor>
    </camera>

This is for TZ70, if you have ZS40, ZS50 or TZ60, then add that model name into <model></model> tag.

I missed the filename:

compact-panasonic.xml

Now I see, that this is about ZS70. However, this workaround may work with ZS70 too, as it is the successor the cameras I mentioned, and as far as I know, the lens is the same one, at least its specifications are the same.

Hi. another question! On the same issue though I think. 

I'm having the same vignette issue with my lumix tz90 camera. I view my images in photos on windows 10. I've downloaded the codecs so the raw file is visible on this basic built in viewer. 

I use both photoshop and affinity to edit. Photoshop seems to auto correct the image but affinity and photos on Windows do not. 

The camera has been in for repair and assessment three times and eventually DK audio, the Panasonic specialist my retailer uses, said they have given me the benefit of the doubt but as they can't replicate the fault on their kit its still back as no fault found, pretty much accusing me of deceit. 

They checked the camera, cards and eventually said it must be a software fault. My system has been completely refreshed in store, new copy of Windows 10 and everything else removed from the hard drive so in a brand new condition with no clutter. 

The problem still persists. 

The really confusing bit is next. 

I went on holiday. I came home and put the memory card in the pc. I transfered the images. I reviewed the images. I noticed the issue had started mid morning in the middle of the holiday. 

One image was fine, the hext had this vignette effect and every subsequent image has the same. 

An hour between a good photo and a whole raft of poor, unusable raw images. 

The camera has a great exposure bracketing setting and is fantastic to use for HDR images and Affinity has the best HDR merge output of my editing suites so really I am stuffed. 

 

Any ideas to help would be greatly received, I'm going mad with this. The people in the shop can see the fault but the people in DK audio think I'm a liar. 

 

Thanks in advance. You could be a life saver.
