following nadir was made with:

1.6x crop camera
8mm SAMYANG Fisheye lens
in result 12,8mm focal length (35mm equiv)
Merlin / Panogear Panohead
TC Handcontroller calculated the pano pattern used so the merlin is not visible.
height of tripod & ballhead: 114cm
distance from tripod leg to tripod leg at the base/bottom: 61cm
the pano image is displayed with 100% - created with panotour pro 1.8
screenshot was resized to 50%
I placed the NPP exact 4,9cm from bajonett (eaxct on outer side of the golden ring of the Samyang 8mm lens)

maybe you post other setups & resulting nadir... ;)

Georg

PS: sorry for bad IQ (snowy winter day indoors at 5pm - not bracketed - 400 ISO - no single lights switched on - no flash...)

Hey Georg!

Good idea!

This is a Nadir from Panoneed with y Canon 5D2 and a Nikon 35mm lens. 45 shots @20% overlap, sphere shot in about 3 Min,
f8, 1/125, RAW.
Tripod was slanted @ about 30°. Vertical correction in APG - that´s why the Nadir isn´t in the center. That in no way does influence the
panorama.

See it here: http://www.360impressions.de/ArchivSchadowplatz/

Will post more.

best, Klaus

here's the footprint of av VRdrive2.
the image is the down cubeface of a sphere.

Not bad at all! :cool:

Which focal-length did you use? The Nadir becomes smaller with longer lenses - because you can have a steeper downlook. I guess you used 50mm?

Hi Georg...

I have been meaning to add to your list...

This again is the VR Drive II using my D90 with 10.5 fisheye. This is a before and after nadir. Using the VR Drive the nadir with this gear is very small so easily fixed in Photoshop using a patch. I did not capture a nadir image. I did not use the clone tool ether.. I will post a D800 nadir later...

Destiny..

yes, it's shot using a "normal" lens. for my Oly that is the Leica 25mm f1.4
since the lenses in the MFT system are rather small I don't think it would matter much if I'd used the 12mm or the 8mm fisheye.
I'll check it out some day later

Doesn´t matter at all as long as the Nadir-hole is smaller than the base of the head . . which Destiny´s example demonstrates most impressively ;)

Also yours and mine examples show the tripod´s base - so a smaller Nadir than the base itself wouldn´t give any advantage.

I realize the smallest Nadir-hole on a sphere when i use my 105 mm lens. Here the downlook-angle is the steepest one i have shooting a sphere.
And because of that the Nadir-hole using the 105mm is the smallest one.

Using the 8mm fe the hole will be larger.

best, Klaus

When your head produce a small footprint it matters how you align it vs tripod, tripod legs, knobs, cables etc.
I will do a comparison fisheye vs normal lens some day. I don't expect them to be very different in the case of MFT system.

It´s not depending on the sensorsize but on the focal-lenth COMBINED with the sensor size.

A 10,5mm on 1,6 crop is about the same as a 15mm on fullframe. So their Nadirs should be comparable - because of the lens-position
on the head which defines the downlook-angle in relation to the focal-length. The steeper the angle the smaller the Nadir.

best, Klaus

This is the nadir (down face of a cube) of my Nikon D700, 14-24mm f/2.8 lens @ 14mm, on a Panoneed head and Really Right Stuff TVC-34L tripod. I'm using a leveling base between the tripod and Panoneed, no ball head or center column, so it sits very low on the fulcrum for very good vibration dampening and stability outdoors and in the wind. It also means the tripod legs stick out a bit further in the nadir, but it's quite manageable. I'd lose the ease of leveling and stability if I added the optional center column, not to mention getting 4" off the deck for low wide angle shots without the robotic head (which I often do). Stitching with this thing is near flawless! I only miss the manual rig on long hikes. Robotic heads are darn heavy!

Great! Ahh, sorry: small! :cool::cool:

Retouching must be very quick i bet . . :D

I don't typically retouch in Photoshop for interiors. I usually use PTGui Pro and viewpoint correction with an off-axis nadir. Largely because I shoot a lot of tiled floors with multiple light sources, white balance, and glare. Photoshop just doesn't clone all that very well. Outdoor nature/scenic shots of course are much easier to just clone it out in Photoshop.

Leifs: one is a 35mm lens, the other an 85mm lens, different photos, different nadirs. I don't understand the question either?

Klause, you must have tucked two tripod legs underneath and leaned it against the railing by the looks? Much smaller without the bag underneath of course.

Well . . . . i added an 85mm Nadir to my 35mm Nadir - as you can read from what i wrote . . :cool:

Guess next week or so i´ll add a 105mm Nadir - if you don´t mind . . ;)

Made by someone who bought her first dslr and pano set a month ago and followed my instructions. I am so proud.

Canon 500 plus samyang 8 mm, Nodal Ninja 3 with Nadir adapter, from camera straight into APG and detection, placed 16 markers.

To make more challeging, I am working on an example with a 50 mm lens and a newspaper on the floor. Who can make a nadir where we can read the newspaper, also in the nadir?

As Always, commerciall work comes first, lot of it lately.

But the test is going well, already have decent pattern, already able to read the whole newspaper on the floor.
Hope to shoot a perfect pattern soon when business slows again. ;-)

Why do you react this way?? I´m always interested in adding informations and learning. That´s why i asked!! :|
