Ive got yet another Photoshop question. Involving Panoramic
Submitted by meyer.dre on Wed, 2009-06-24 07:40.
Hi all.
Hope you can help me here. Ive made HDR pano's for a while now. But i did it the wrong way, I made every pic an HDR THEN i made the pano . Then i realized its better to first make the 3 exposure pano's THEN make the HDR.
Now here is my question:
After i made the 3 exposure Panoramic's I want to make an HDR, But all 3 photos have to be the exact same width and height. HOW DO I DO THAT?? I know you go the adjust image size and type in the width and height manually but that doesn't work as they are linked and as you adjust the width the height changes at the same time.
Thanks in advance for your help

I assume that your images are taken with auto bracketing and are perfectly aligned,
With PTGui you stitch the first set using standard controlpoint stitching. You then save the project file as a template and apply it to the next set of images and stitch without without any controlpoints and optimizing.
You should now have 3 perfectly aligned panoramas you can do HDR from.
With PTGui Pro you have HDR built in and can do everything in the stitcher.
Personally I always use Enfuse and I always do it on the individual images before stitching. It is much faster and you can do individual adjustments if you have a window in the pano with very large range.

Submitted by meyer.dre on Thu, 2009-06-25 07:15.Hi Hans and thank you very much for helping me here. I do use PTGUI and i knew about the save template thing but i was just to slow to think that, that is the solution. SO THANKS! :)
If you do the HDR before stitching then every pic is going to be a little different. Doesn't that cause some bad stitching? I want stop doing it because of that reason.
Enfuse VS PTGUI? what u think?

Submitted by Hans Nyberg on Thu, 2009-06-25 12:54.I have never had problems enfusing the individual images. Ptgui is very good at taking care of small differences in brightness.
The built in Exposure fusing in PTGui is also nice especially if your bracketed sets are not perfectly aligned.
Bracketeer is very slow to do the aligning.
But the stitching takes much longer time as you have to warp 3 times more images if you do 3 sets bracketing.
Enfusing the individuals is much faster.

I use Enfuse Droplets to composite my source images before stitching and they come out fine
The thing you have to do is composite the source sets with the same corresponding exposures and apply the same "tuning" to all the sets if you use one of the GUI interfaces that can adjust the blend

The other problem i find in doing the HDR proses first and copying all the tuning setting etc over to each photo. As you stated above. Is that if i do the "tuning" on a picture then those same setting will never work on the other parts of the picture if you have a sun/shade scenario with a 360 picture. So if you do it the other way around you will have a view of the entire 360 photo and do the "tuning" according to that.
I would like to hear your comment on that plz
Thanks so much

You should actually try it, instead of theorizing
The whole purpose of HDR or Enfusing is to compensate for dramatic bright to dark changes in a scene.
I start with the set of shots that has the "window view" that I'm trying to have show and then blend the photos with the same shutter speeds from the other sets.
Some times I get the "view" but the rest of the stitching image is darker than I want, so I just use Curves in Photoshop on the dark end of the scale, brightening it while have only a little effect on the bright part of the equirectangular projection
It all depends on how big the "Bright/Dark Range" is. A restaurant I shot a month ago, has dark carpet, dark walls and a dark ceiling and really big bright windows facing the street. I dout you're facing anything with this broad a Bright/Dark Range.
It came out fine doing what I described above

Submitted by meyer.dre on Tue, 2009-06-30 07:19.Thanks Douglas, the reason im theorizing now is because i dont have my VR tripod head, I should have it by Thursday. I have done some tests with my normal tripod but the stitching is to bad, that i dont want so waste time testing on it.
Thanks for sharing your information.
Thanks
