If I pre-process my HDR raw images in a third party app (and combine to get 1 HDR image) and get the HDR lighting just right, like an evening scene that looks like evening, then take it in APG... APG tries to turn it into a day scene by lightning everything up, and I wind up trying to post correct it back to a evening scene.
Yes... APG has a edit/Levels control, but that does not provide the control one needs to match the original processed HDR image.
Just wondering if any one else has run into this problem and how they solved it?

you need to switch OFF the auto color correction in this case, that's messing it up.
Set color correction to NONE.

and make sure your external software does not edit/change/delete EXIF data saved in your raws....
post/prepprocessing files often leads to changed EXIF data. After processing the images you can reiumport the exif data, e.g. with:

Could you explain EXACTLY what you did? There´s no HDR RAW images. Processing bracketed RAW shots to HDR: what kind of file do you save:
.exr, .hdr, .tiff 8, .tiff 16
Putting .exr or .hdr into APP/APG i think isn´t a good way.
Depends on what kind of files you need afterwards for which purpose.
Do you need .hdr as a rendered result?

Digipano:
Thanks. Tested. That works great.
Gkaefer:
Good point. Thanks for the link.
I know I'm jumping the gun, but how would you reiumport the exif data?
Klaus:
I need to pre HDR the images because I crash APG with 3 row, 8 images ea, with a 5 image HDR bracket per view (120 total images) (previous post). Plus I did not like the lack of HDR processing control in APG.
I use HDR "Photomatix", and final image is Tiff, 8 bit.

I'm doing the same thing, but in Photomatix Pro I'm using exposer blend mode (its called fusion in the latest release) Some where along the way the EXIF data is lost.
Here's my work flow, process the bracketed images in ACR with out any adjustments and convert to 16 bit tif. ACR is supposed embed the EXIF data when converting to tif. Then, depending how many images there are, I either do batch convert in Photomatix pro or manually select them.
I then bring in the HDR images to APP.
The image that APP outputs looks great, but if it had the EXIF data, what difference would I see?
In the folder I tell ACR to save the tif's files to, there are two files that say Bridge??? I assume that the EXIF data are in those files, how can I get the EXIF data back into the tif? A better question, why isn't ACR embedding the EXIF data in the tif's?

Mr. Moose, pardon my naiveitivity, but what is ACR?

Adobe Camera RAW is the Photoshop RAW image converter.

Hi Marv!
I always process my bracketed shots in Photomatix first and make them 16bit/Tiffs. (when you shoot bracketed you can use jpg without problems - 3 different exposed jpgs contain more information than 1 RAW).
After that i feed them into APG and after stitching/editing i render 16bit Tiffs in the end.
This way i can use the very, very good and helpful Color Correction with it´s anchors.
IF you really NEED HDR as output the way to go is to feed all bracketed shots into APG, stitch and edit them as bracketed layers WITHOUT Color Correction and render 3 bracketed layers (just add %L to the pano´s name) and save the three layers as 16bit TIFF.
These i feed into Photomatix and generate "real" HDR as output - without tonemapping/fusion - to be used as IBL in Maya, Cinema 4D and other 3D animators.
This procedere only makes sense when you need an .exr or a .hdr sphere for IBL (ImageBasedLighting) in 3D applications.
best, Klaus

Thanks for the great explination Klaus. You got me thinking about my work flow.
I only need jpg as final pano at this stage of life. However... I shall render in Photomatix 16bit Tiff (Du)... and try APG Tiff 16bit output and see what happens to web playback preformance on different devices.

reimport - my above first link is to a non freeware....
so here is a freeware that works also in batch to import exif:
http://freeweb.siol.net/hrastni3/
its an gui to the also fre cmd line tool exif tool.
mark all images you need to import exif data to...
export/import->restore metadata...

Gkaefer, thanks, that is a big help.
I just barely got it as he's shutting his site down. See msg below.
[i]"Notice!
Because I have switched to another internet provider,
I can't maintain these pages anymore. If you can still read this

As it seems, my new internet provider doesn't offer any

ExiftoolGUI and other projects I had in mind, are frozen.

BTW, I remember that one APP v2 goal was to be able to make some 'enfusing' inside APP. Alexandre, you talked about something like 1 -> n or n -> 1 stacking... Is it always planned? That would solve a lot of situations...

I saw it!
perhaps kolor could sponsor a wikipage to host this tool.
seems to be only static pages plus some additional (non project related images).
but on his website I did not see an hint to his email adress....
