INSTA PRO 2 = DNG/JPEG HDR MODE / PT GUI ?

[Brice Genevois]

Hi,

wanted to know why my DNG bracketing shoots with InstaPro2 are not recognized by PtGuiPro like HDR shots ?

in JPEG is the same

could you help me please ?

thanks

[PTGui Support]

Hi Brice,

First of all make sure you are running the Pro version of PTGui (see
Help - About).

Secondly, the exposure should be loaded in a repeating sequence. For
example:

Shot1 -2 EV
Shot1 0 EV
Shot1 +2 EV
Shot2 -2 EV
Shot2 0 EV
Shot2 +2 EV

I think the InstaPro uses a different ordering by default (first all
-2EV shots, then all 0EV shots, or similar). You would need to re-order
the images.

If you can't get it to work, please post your project file here (after
loading the images).

Kind regards,

DNG is a container format, which usually contains raw image data. Once
PTGui processed the images they are not raw any more. Use TIFF instead.

Erik, is it possible to have PTGUi keep the processed stitched images in with all the container format?

I cant edit my drone 25 DNG individually, so I pass it to PTGui to stitch first, then use my photo editor to do the edits. That's why my question above.

[PTGui Support]

Hi Philip,

DNG output is on the wish list for a future version. But you can just as
well use TIFF, there's no technical advantage in using DNG for processed
images, it's not a raw image anymore.

No. The DNG files contain raw sensor data, which needs to be converted
(some say "developed") in order to be processed by PTGui. If you feed
the DNGs directly to PTGui, Libraw is used for this purpose. See also
https://ptgui.com/support.html#3_7

If your photo editor can't open DNG files, it wouldn't open them if they
where produced by PTGui either. However, if you create your panorama as
16bit TIFF, you should have enough latitude to do the necessary edits.
If the DNG files are in HDR mode you can also stitch to EXR or 32 bit
TIFF, to maintain the full dynamic range.

It wouldn't be beneficial to do individual edits on the source images
anyway, since PTGui needs them all the same to process them correctly as
also stated in the above linked FAQ article. Please read it thoroughly...

Hi everyone
Tiff is just a photoshop format
We need DNG to edit our panoramas using the “native Raw way” wich is essential for photographers
Example: Using Insta Stitcher I can export JPEG + DNG Raw for each panoramic picture

Maybe you dont understand my question.

I have 25 DNG photos that I shoot from my drone.  I can't edit each file individually until I have stitch them together.

That is why I save the 25 DNG as TIFF, pass it to PTGui to stitch.

After PTGui is done stitching, I WISH it retain all the RAW container.  I even save it as PS (Photoshop format).  Its no use.  The dead giveway is now the Temperature is now -100 to 100, instead of 2K to 5K.

[PTGui Support]

Hi Philip,

Yes I think I understand why you ask. But please keep in mind that
stitching (and many other image processing tasks) require demosaicing
and color space conversion first. A panorama cannot be a RAW file
anymore, stitching requires developing the RAW files first.

Now the DNG format allows embedding non-raw image data as well, and I
think Adobe are treating this the same way as RAW files. It's not RAW at
all, there's no image quality advantage, I think it's an artificial
thing in Photoshop, but I understand why it would be useful to have.

As I said it's on the wish list.

TIFF is much older than photoshop, created by Aldus (which was later
acquired by Adobe) and DNG is also just an Adobe creation. And as a file
format it's basically TIFF with some meta data.

The "native raw way" would be to work on raw sensor data, which by
definition is not altered in any way, especially not interpolated or
warped (which a panorama always is). Of course such an image can be put
inside a DNG container, but it's not raw anymore.

[Brice Genevois]

Hi Erik
you mean that is not possible to get a DNG panorama after stitching ?
And I get them with insta 360 stitcher why ?
this software is really not performant but I got DNG wich is more important than stitching

Outputting to DNG should be possible. It's not a RAW image, there is no
quality advantage, it's just that Adobe requires you to use DNG.

Brice, You can open TIFF and JPEG files in Camera Raw.  Enable in Camera Raw preferences.

[PTGui Support]

Thanks, I wasn't aware of this!

Actually you can create a TIFF panorama with PTGui, open it in Photoshop
and then do Filter - Camera RAW Filter. This would give you the same
options as if PTGui would create a DNG.

That option doesn't appear to be available in CS6 so wouldn't be an option for me.

You also can pass any file to Camera Raw from Adobe Bridge.

Camera Raw filter is available in any PSD readable Layer

you can even create a smart layer from the Pano Layer and apply camera raw filter to it. and Adjust, Adjust,....

To have all available Tone (color) Information, 16bit or even 32bit could transport it
32 bit is a bit more difficult to handle...

and this might be not available in older version of PS

CS6 is a bit outdated .... some 10 years old.....

Indeed it is old, certainly, but it continues to work well - now with Windows 11 - and does everything I need.  I do need to make use of the DNG Converter to maintain compatibility with newer cameras.
