Park Panorama

[Kamil]

Hi, this one I made last year. It´s an almost spherical panorama made with GRD. The combination of tripod and the interval shot function is very cool, although i would like to have a wider exposure bracketing for DRI / HDR.
I suppose, it´s not possible, to include the .mov file into the thread, so here´s the URL. It´s approx. 4 MB large and, you´ll need Quicktime to see it.

Simply click and drag to rotate the view.

Nice pano kamil!
28mm or with wide angle adapt.?
How many images and row angles, portrait or landscape, % of overlap???
Did you use a pano head, if not which software used?

Hello Luis, many questions, let's go:
- made with 28mm
- don't remember exactly, but it were more 30 images
- camera was set up in a selfmade pano head in portrait mode
- overlapping... maybe 20 %
- 3 rows (bottom, middle, top) + 2 crossed images for the ceiling
- software was all freeware, based on the hugin GUI with the needed additional freeware programs, hugin needs

With 28mm (4:3) more than 30 images will result in mutch biger overlap, with 9 shots per row you will get something like 33% overlap, which is fine!
How many ajustable axis have your selfmade pano head, you have shot in portrait so i will bet in one! Can you post some pics of the pano head?
I have one in mind, a simple plate, just 1 axis for nodal point adjust in LANDSCAPE position, the problem is that it will rotate out of the nodal point when you tilt it for the up and down rows, here's a sketchup:
(I think this will work for outdoor panos but the out of nodal point rotation will give problems in small indors)

Ok, here are some pics of the three angles I used (maybe it's not exactly the same setting. just for demonstration).
I know, this so called "pano head" looks pretty silly
It's also not very robust, but it rotates the lens very good around the nodal point, so there is no parallax when overlapping the pics.
I built it on a boring sunday just before I made the park panorama. It was adjusted by trial and error but in the end it works quite good. The camera is normally fixed by a strap or something. The rotation around the vertical axis is done via rotating the tripod's head, also around the nodal point.

Great pano Kamil! I would like to see you in the park when you take the shots with your "crazy" pano construction :lol:

Opsss, Sorry! I made a wrong interpretation of the word "PORTRAIT"!!! Its the quick/diagonal read sindrom/efect...so,

With 28mm (4:3) more than 30 images will result in mutch biger overlap, with 9 shots per row you will get something like 33% overlap, which is fine!

The quoted text is true for LANDSCAPE!
PORTRAIT 28mm (4:3) with 10 shots per row you will have an horizontal overlap of 22%!!!
My simple Plate just works in LANDSCAPE and the tilt is done in the tripod ball head this will result in an out of nodal ponit rotation but with some tests i can get the correct nodal position for the tilt angles and mark it on the plate (i've to edit some text in the other post... )

Your head works and with proved results, its a great mechanical work, congratulations!!!
(And its really small when compared with the manfrotto pro head)
Whats your tilt angle, 45º?

There are some disadvantages with this metal thing. The first one is, it only fits the GRD, but as I don't use another cameras and also don't do much panos, that's ok for me. It's also hard to reach the shutter button, when the camera is mounted, so I start the interval mode, before mounting the camera and on the first few shots you can see my head or something while mounting the cam. The construction also tends to vibrate when it's windy, so wind and long exposure times are not the best combination for this kind of construction.

I think, the tilt angle was 45 degrees. On the pics there's one tilt position missing, when the camera is pointing directly to the top. I used horizontal, +-45 degrees and 90 degrees for the park pano, as I remember.

Great pano Kamil! I would like to see you in the park when you take the shots with your "crazy" pano construction :lol:

Hehe, it looks unspectacular. I'm just standing there and rotating the tripod head every 5 seconds or something.
