Can APP handle a hand held bracket for fusion?

by Bmachine » Sat Oct 22, 2011 11:54 pm

OK, clearly, in an ideal situation, a bracket should be done on a tripod with a remote, etc... But sometimes when you are hiking out you don't happen to have one with you.

APP is excellent at stitching panos that were shot hand held. But what if I want to do a bracket for each frame ... also hand held? Obviously the bracketed images will not register perfectly. But since APP is so good at stitching hand held panos, how does it handle hand held brackets on top of that in order to create an Exposure fusion pano?

Obviously the best way to find out is to try and I have been working on that. But, as many others have pointed out already, the docs for fusion are sketchy at best or mostly non existent. So I have not been able to get anything to work in terms of the workflow described here:

http://www.autopano.net/wiki-en/action/view/LDR_/_HDR_-_Workflow_case_B

I think that many important steps are simply not written out in that tutorial.

But I digress.

Thank you

No way... its hard enough to get it right with a tripod... If its just one single bracketed shot, you might stand a chance depending on the exposure time... other than that.. good luck!!! Even more so in apg... LOL...

I did a lot of my panorama with HDR ( 3 brackets ) and totally handheld ( for 360° too ). Most of the time, you can still get quite good results, but some errors at hard edges will still remains.

maybe load them into autopano but do not group the photos by bracket. Helped me a few times when people were moving through the shots in brackets.

When doing handheld, you need control point within the stack, so disable the hard link option if selected.

UPDATE.

OK, I re shot my pano with a tripod and a Nodal Ninja 3 head and this time I did a 3 step bracket ( -2, 0 , +2 ).
I then redid the pano trying to follow the instructions as close as I could.
In "Group Settings" > Panorama, I grouped in layers by speed
In Render settings, I selected Exposure Fusion.
Then I set Multiband to -3. This, btw, unchecked the Exposure Fusion button.

Result? Excellent!
Now, since I use APP, I don't have fine control over the fusion but I find the resulting image really quite good for "out of the box" render.
So in my case, the problems I had were clearly operator error. Following a cleaner shooting process and following the instructions closely (especially re: grouping) solved my problems.

Thank you Alexandre.

A creek in the shadow of trees, with high sun burning some areas. A recipe for exposure disaster.

Hey... Is was that taken in Aus, look like it....

I have had susses in taking hand held bracketed shots but only using a normal lens with a bubble fitting on top of my Flash Shoe.... You can buy those in different arrays.. As for a fish eye lens hand held with bracketed shots, no way... apg will do a great job of stitching normal images but where possible most defiantly a tripod...

I like this shot but I think it needs more tone and and playing with... If you did all this in apg using fused images LDR then well done... Try putting your images into Photomatix... I think this images might look nice as a HDR too...

This pano was actually taken in a suburb of Los Angeles where I currently moved back to.

The image was not cleaned up and tonemapped. It is a straight 3 step bracket 7 images pano with all settings to default (except Multiband to -3 as suggested on the APP site) coming out of APP.
