Re: [hugin-ptx] 2010.0.0 on OSX 10.6.8?

I stitched this panorama  
using Hugin 2012.0.0-RC3 (while having older versions available on the 
same machine).

That version works great on my Intel Mac / 10.6.8


I have run into problems when trying to install/compare multiple versions -
I suspect newer versions of Hugin don't play nicely with older versions
of PTBatcherGUI (or vice versa) which is why I've been slow to upgrade
beyond one that works for me.


Just use the PTBatcherGUI version that comes with the respective Hugin 
build. As long as you keep both in the same folder everything should 
work fine.


If you have more than one version (I often do that for some tests) 
double clicking projects won't necessarily open the latest version. You 
also might see a message that the stored prefs don't match with the 
current version.


But the thread was about images not being displayed in the control 
points tab. I suspect this is a temporary memory glitch on that 
particular computer but still don't know if this happened more than once 
on that Mac. Seeing a .pto file and an error message (from console.log 
maybe?) would be great.

Re: [hugin-ptx] Re: Visualize seam

[JohnPW]

It looks like Stephan Peter made the fix. But I guess it was a functional 
error rather than a fatal one as described in that thread.
In this case it appears to be the cause of the stoppage. But perhaps 
there's more behind the stoppage than just this bug.

 Read the Enblend manual about the following options:
`--fine-mask', `--optimize', and in particular `--visualize'.
Together
they might take you close to where you want to get.

Re: [hugin-ptx] Re: Hugin -> Faux Exposure Brackets -> enfuse

[JohnPW]

Yes, that's what I was alluding to.
But what about what I'm asking below?
Theoretically tiff 16 bit tiff brackets converted from a 12 (or 16 bit) RAW 
file contain more information than a single one. But in practice is there 
really much difference between enfusing them and making faux bracketed 
images from that single 16 bit tiff using this technique.
How much difference, theoretical and practical, is there between the two 
groups of intermediate images?

Hmm . . .
Google tells me that this is a problem that some of you (Gnome Nomad, kfj, 
et al.) have seen and fixed before. A bug that sets the compression 
incorrectly:
As seen Here: http://markmail.org . . 
.

Perhaps calling --visualize (Im using "2012.0.0 built by Harry van der 
Wolf" on OS X 1..8.2) brings up a similar coding problem from a similar but 
different place?

Re: [hugin-ptx] Re: Hugin -> Faux Exposure Brackets -> enfuse

[JohnPW]

Actually, I was curious how using this script on a high bit depth tiff 
extracted from a good RAW file would compare with:
enfusing 6 tiffs extracted from the same RAW file at 6 different exposure 
levels.

In other words, given RAW and tiff files with similar depth of information 
how does the sigmoidal contrast setting compare to RAW conversion?

Clearly RAW conversion isn't even an option on jpegs. But I'm curious about 
how similar these two approaches are both theoretically and in actual 
practice.

My understanding of basic concepts of image manipulation is not great, and 
my initial thought is that the approaches are totally different. (the 
intermediate files don't look like different exposures in the way actual 
bracketed shots do.) But after reading what little I found on sigmoidal 
contrast and considering what little I (think) I know about RAW files, I 
start to think that the manipulation may not be so different as I initially 
thought. Perhaps the destinations these two winding roads lead to, are 
nearer each other than I thought!

The main thing I notice with this process is that the highest of the 
highlights seems to get slightly blown. But is this a result of the 
strategy itself or just the finer points of it? Perhaps some adjustments 
might make a difference, say the sigmoidal contrast settings — perhaps the 
contrast factor needs to be edged down bait? Or maybe the weighting of the 
enfuse settings should be different from the defaults? Or is it inescapable 
with this process because of a simple principle of image manipulation 
theory? Or maybe it's inescapable even with full access to a RAW file?

I don't know, I'm just curious. To me it's an ingenious process in any 
case.  :-)
If anyone can tell me, or point me to a good resource, I'd love to hear 
about it.

John

RAW should (potentially) have a little more data available than a JPEG,
so the results

48-bit RAW has 16-bits per color channel. JPG only has 8.

[hugin-ptx] "degrees of view" always for equidistant fisheye?

[Torsten Bronger]

Why do the "degrees of view" in Hugin's "Camera and Lens" tab always refer 
to rectilinear or equidistant?  I can choose stereographic, equisolid, 
orthographic ... I only see the FOV for the equidistant case.

Hi,

the latest hugin 2012.0.0 works great on Intel Macs with 10.6, so just 
download the new version if you don't use a PPC Mac.

http://hugin.sourceforge.net/download/

If you're on a PPC Mac: Hugin 2011.4.0 works on my G5 (PPC)


I think I also saw the phenomenon you described once or twice but don't 
remember the solution. It might be related with the format of your image 
(JPG? TIF?). Does your project contain a large number of images?


Have you tried resetting your preferences?

Do you have some other programs running at the same time that may 
consume larger amounts of your RAM?

Today I started to work on a backlog of summer photography -- lots of
panorama sequences. I ran across one troublesome image and wanted to
tweak the alignment points manually. As I recall, the way to do this was
to bring up the Control Points screen, which displays 2 images at a time
(selected from the menus above each display area). I used to be able to
adjust alignment points quite precisely using this interface.

Today, to my surprise, the images are not displayed below the menus. I
can select the images (and the menu is sensible, i.e. matches the image
names), but no image is displayed: most of the screen remains blank.

Is this because I am using an old version of Hugin? My OSX is a bit out
of date too, so I'm nervous about upgrading blindly to the latest greatest.

[hugin-ptx] Re: colors and brightness change when stitching

[kevin360]

Michael,

Something else you can try, add "--no-ciecam" to the commandline for 
enblend and enfuse, see if that makes a difference.

Ciao Michael.
I'm an avid fan of hugin, but for stitching microscope photos I recommend
http://www.xuvtools.org/, which is especially adapted for this task.


Michael,
If the limitations of xuvtools make it unsuitable, try hugin again, but  
set the EV for each image to be equal to the highest EV of your set of  
images. I have had some success with that approach for some problems.


Cheers,
