In APG how do I add the shot looking straight down (that I shot when I move the tripod out of the way), to cover up the other shots with the tripod legs, etc? Do I have to go in PS and mask the other shots with the tripod legs, or is there a better way?

Marv this one is a great tutorial for adding Nadir shots

Hi Marv, I have been using the above alpha channel mask quite a lot recently whilst learning APT and noticed that you can drag/drop the alpha channel to other such images so you don't need to paint it multiple times. (Apologies as also a newbie to this area of PS for those that are saying this is obvious!) Not found out how to save the alpha channel as a mask for other nadir shots given it will show the pano head in a similiar position each time.
Digipano: I noticed that APT creates six cube faces for the tour. Is there anything against editing the nadir face post APT creation?

Basically: no. But i prefer working with higher resolutions and downsize them only in the end to be used in a pano/tour.
So i generate high-rez equirectangulars, generate cube-faces, edit the bottom or top face and make an equirectangular again to be used in APT.

I see. Same editing can be done but at a higher resolution. I see that KRPano Tools has a droplet to create hi-resolution cube faces. Is this what you use to create the cube faces?

Nope - i use CubicConverter (Mac only).

Many thanks Digipano and others. Works great.
BTW... I discovered a great program for HDR that gives you unlimited HDR control "Photomatix" http://www.hdrsoft.com/index.html
Just preprocess your HDR there first and then take the processed tiff in AP.

ENFUSE is another application Marv to give a try. Does exposure blending very naturally and it is freeware. There is also a GUI available for it. Just drop your bracketed images, select the output and away it goes.

ah yes - the newest version of enfusegui has the nice feature that if you drop 10x3/5/x bracketed images as result 10 enfuesd final images are produced. so no longer needed to do it step by step 3/5/x bracketed images of image1 -> enfuese than next braceted set...

Ok... I said the NADIR worked great and it did until I got it in APT Beta 6. When I look up at the ceiling the image rotates around the NADIR point (Pano #2) instead of up and where ever you want to look as in my first try (Pano #1) without the NADIR shot, where I just used 3 row x 8 images each. (I hope that makes sense).
My bottom view point works like it should in both #1 & 2... where ever you move the mouse... you go.
I did notice the following in the APT Beta 6 Panorama Properties box:
#1 try.
Compute Optimal Size: Partial Panorama Width 3770.
#2 try.
Compute Optimal Size: Cube Face Size 1200.
(Both were rendered with the same settings in APG).
What's going on here... Why is one a "Partial Panorama Width" and one a "Cube Face Size"?
I also see that on #1 there is a Box for "Nadir Patch" and a "Scale" box. What is this for?
Also interesting is that (keep in mind these are straight "test" rendered and not adjusted in any way (just dropped in APG and rendered).
#1. Center of image is my first shot.
#2. First shot is the 1st left image.

Well - maybe you could SHOW us what thew heck you exactly mean!? I can´t imagine your problem from "#1" or so when i don´t see "#1" . . . . . . . .
Besides: there are not really tons of APP/APG/APT tutorials - but the basics can be found.

Because APT 'sees' one as an equirectangular image with 360180 coverage - that's where you have the cube face size option - and the other as a partial pano with less than 360x180 coverage.

To allow you to specify an additional image that will be placed at the nadir - scale allows you to specify its relative size.

Klaus:
Thanks, but I blundered my way though and found it. Under "Data Field of View" the "Vertical" and "Vertical offset" had changed (on it's own), so I set both to Image #1 settings and all was fine.
Andrew:
[and the other as a partial pano with less than 360x180 coverage.] Correct me if I'm wrong... but what you are really saying is that inspite of getting enough rows of images to have full 360x180 coverage... you still need at least a nadir shot for it to count as a true 360x180 for APT... correct? If I am correct... and I'm not sure how to say this... but "So What"... they both worked, and look identical except a tripod is in one. Or did I miss something here?
Many Thanks.

No I'm not saying that at all.
If you use a spherical projection when stitching and set 'Preferred extend' to 'maximum projection range' then you will have a 360x180 as far as APT is concerned regardless of whether you have image data covering the entire pano FOV. In other words you may have 'holes' at the zenith and nadir but it would still be a 360x180 as far as APT is coNcerned.
OTOH if you leave settings at default which I believe is 'Clamp to panorama content' and you do not have image data covering the entire spherical pano FOV then you will not have a 360x180.
APP/APG creates a custom EXIF tag with data about the pano FOV (and other things) that can be read by APT to set those parmeters automatically. But...if you post-process stitched panos before Using them in APT then most post-processing software will strip out this EXIF tag and you will have to enter the correct Data field of view values, esp. in the case of partial panos, yourself.

Many thanks Andrew for your great explination... and the screen shots. A Big Help, and explains a lot.
Yes, I've made the EXIF tag mistake post croping in the past. I've never had a problem post retouching, or adjusting tones yet with CS4 (knock on wood).
