Undo aspect ratio GX7?

Hi. I'd like to know that if I set 1:1 aspect on my GX7 and shoot raw+jpg, is there a way to access the uncropped 4:3 image? Have tried to search but I haven't found anything that works on either SilkyPix or ACR. Found the DNG recover edges plugin in AdobeLabs but AFAIK it requires Lightroom. Actually they state that it doesn't work with Panasonic cameras because the cropped areas are irretrievably lost even in raw. Can anyone confirm whether this is true?

I was always under the impression that the RAW file always captures the entire 4:3 image. Both SilkyPix and Adobe software forces the embedded lens corrections profiles so maybe it also forces the aspect ratio also. Maybe try another raw processor like RawTherapee or Darktable?

Funny - but I was sure that I'd been able to this for 1:1 RAWs in Lightroom....

Perhaps those times weren't when the image had been made using a Panasonic camera and a Panasonic lens.... as I now can't get it to work with a GX7 RAW, shot in 1:1, and one of their lenses!

Memo to self, to be sure to check.

I don't know about a GX7, but I just tried it on my GX9. I was expecting the RAW files to have the full sensor image, and they did. Affinity Photo didn't even know they were supposed to be 1:1 and showed the full image. So did the Mac's finder. The file sizes are also the same, which is a good sign. A 1:1 actual crop should be 25% smaller.

In Silkypix (Pro 10), I set the crop and I could drag the crop edges outside of the 1:1 frame and get all the 4:3.

You could try an application like FastRawViewer to see all the RAW data. Which also shows the 4:3 data for me.

I'm pretty sure for the GX9, the aspect ratio is just an EXIF note. It seems it's crop instructions:

Crop Top : 8
Crop Left : 656
Crop Bottom : 3896
Crop Right : 4544

I would be totally gobsmacked to find the GX7 did it differently.

If it does do it this way, you could mess with the EXIF data and Silkypix or ACR would be none the wiser.

Interesting. I always thought the same.

Maybe I’ll dig out my GX7 and try a few shots, with a couple of different lenses to see what happens. I have Capture One Pro 29, so maybe it’ll doing something different.

Also, I’ll try importing to my iPad Pro to see what happens.

Barry Twycross should have the right answer.

In case of RAW, no matter what is the aspect ratio been used, Panny camera will always save the image in full 4:3 resolution.

The following is a tested shot on RAW, but shooting at 1:1 format. Review of that RAW file on the back LCD of camera will show 1:1. However if that RAW was opened by a non related RAW converter to Panny, e.g. the Dark Table, we can see the RAW is actually in 4:3 format.

The following is a screen snapshot of that file under Silkypix:

Since Silkypix is a compatible RAW converter to Panny camera. It knows the file was originally shot at 1:1. The Red Box was the RAW file at 1:1 (same as review on camera), but we can actually use the cropping tool to reclaim the hidden area back to full resolution in 4:3 format.

But we can't revert a 1:1 SOOC jpg back to 4:3.

When shooting RAW at 3:2 or any other aspect ratio besides 4:3, with the GX7, that's what you will get in Lightroom. You can't recover the 4:3. With my GX80, it WILL show the full 4:3. when opened in Lightroom even if you have shot it in something else. I have both and wish it weren't so for the GX7, but that's the way it goes....

Your right.

Took out GX7 to test again, despite in FastStone it show the RAW in 4:3 (back stripes on both sides), no way to convert the RAW into 4:3 format as I can do so on GX85 and G85 RAW...

With RAW files from the GX9, reverting from square shape to the full 5184*3888 image in Lightroom is simple - just click "Reset" as soon as you've got the file open in the Develop module.

Odd that they didn't set all previous models (except those that actually shoot different areas - LX7, LX100 etc etc) to work that way, but - to be honest - I prefer shooting to the full sensor area, and then choosing my own crop!

to all for your input. I tried Raw Therapee to no avail. It seems that the 1:1 setting is irreversible, at least without some serious digging. Maybe I should add that I don't absolutely need the ability. I just experimented as the square format intrigues me. Having the view set to 1:1 obviously helped me compose for square but it might be better yet to have some kind of 1:1 frame superimposed on the 4:3 view. As the GX7 doesn't provide that, I'll try to make one to put on top of the screen. Tried Scotch tape. Was too ugly. Maybe try 3D printing for 1st time:-). Example of what I got out of my little experiment:

An obvious case of 1:1

Panasonic's/Silkypix' default idea of B&W seems to be sepia. I happened to like it in this case, so didn't convert to neutral. Also more flattering for people, I've found.

So far I found GX7 will not. Weird 🤔?

Would try the older models to see would GX7 be the only exception.

GH1, GH2 and presumably GH5s  saves the raws in the defined aspect ratio (4:3, 3:2 or 16:9) because of the multi-aspect-ratio sensor. I am not sure how 1:1 is saved (as 4:3 I guess).

I would assume that JPEG embedded to the raw file has the aspect ratio selected from the camera. In theory it is possible that the software is not actually working with the raw file, but JPEG (or even the embedded JPEG on the raw file).
