Hi Michael,

I'll take a look, could you post your project file?

Hi Joost,
thank you, that was exactly what I found out, but: "The
editing of all the 'false' exposure times can be lenghty...." Because
the software doesn't have a "TAB"-function, so you have to edit let's
say for a set of 3x3 pictures 9 values by clicking and typing a.s.o.
PS actually keeps the EXIF's, only by some circumstance the values may

hello,
I've been thinking about having part of a 360 panorama made up of lots
of photos and the rest just 4 photos say.
Would I have to scale up the "low resolution" photos so that the
content was the same size in pixels as the many smaller photos ?
Otherwise it's a pain to take lots of photos all around if they really

... i tried a lot. - ghosting.

its getting me mad, those ghosts.
since i have to do a couple of outdoor panos i am looking for a good
(or any possible) solution for the ghosting problem.

problem:
couple of panos shot with 5d and 15mm on 360precision and nodal ninja.

- lots of moving branches and leafs -

Re: Yet ANOTHER Nadir question...

2009-11-25T17:15:32Z

Marcus, If you output a blended + layers psd file, you should be able
to discover the origin of the hole fairly easily. (Maybe bring the
nadir to the centre of the output area for convenience). If you have
covered the nadir adequately in all your shots, then obviously there
should be no hole if the blender is doing its job correctly.

Yet ANOTHER Nadir question...

2009-11-25T16:49:26Z

A small mystery that I've tried to work out myself, but haven't. I use
John Houghton's nadir method of making masks etc. All drops into place
well. BUT, I often get a small gap in my nadir. This is easy to patch
when shooting on grass, tarmac etc but obviously gives problems when
there is a lot of detail. I have always thought it must be something

A few google searches have turned up plenty of info - (and more than a
few flame wars) about the difference between exposure fusion and HDR.
What I'm really not found is much in the way of discussion about under
what kinds of circumstances and shooting settings one should consider
when choosing between processing between the two, and I suppose by

Hi Michael,

You can edit the values in the Image Parameters tab (in the columns
Exposure Time, ISO and Aperture). If you enter the correct values there
PTGui should to recognize your bracketed sets.

It sounds like PS did not save the EXIF data with the edited photos.
You may have to add it back in so PTGui can read it.

Hello,
I have tried to stitch a set of bracketed photos with the same
bracketing sequence. I wanted to erase the tripod from the nadir
photos and edited them in PS. After saving them as TIFF and loading
them into PTGUI the software did not recognize them as a common photo
set belonging to the others and therefore did not start the hdr

Hi Joost,

I think the benefit to Erik wouldn't be one of a technical kind, but
of a workflow kind. E.g. to fix ghosting, alignment, etc. issues or
selectively choosing particular bits of a layer (a bit of sky that
happens to have a flock of birds in it that the default blend got rid
of but actually looks nice if kept in). Right now Erik would have to

Hi Erik,

This has been on the wish list since Luzern..
But I'm not convinced of the benefits; photoshop internally uses cropped
layers so the disk space usage will be about the same. And the blenders
will need to blend approximately the same amount of pixels.

Re: [PTGui] HDR corner case issue, single valid data above/below white/black threshold in alpha masked bracketed set

2009-11-25T10:05:02Z

Hi Dave,

The HDR merger in PTGui was not designed to be used with partially
masked images, so this is not surprising. But I'll see if this can be
improved.

HDR corner case issue, single valid data above/below white/black threshold in alpha masked bracketed set

2009-11-25T05:14:45Z

I am working on a HDR panorama. Unfortunately, there are a bunch of
people in this one. Thus, there is a significant amount of movement
between the different bracketed images which causes ghosting. I have
been attempting to reduce/eliminate this by alpha channel masking the
LDR files on all images. In this set there are 6 bracketed images.

Hello Joost,

Can we have a "merge non-overlapping images" option on Create Panorama tab?

I'm currently experimenting with a large mosaic shot handheld (from
multiple viewpoints) and I almost drowned in layers.

For now I did it in photoshop manually and reduced 62 layers to 7 this
way, but this is pretty tedious. But I think it would be beneficial for
