Nikon 10.5mm / Samyang 8mm lens and D7100 or D300

Hi,
It would save me a lot of time, if someone could share NNP settings for above lenses and camera bodies on NN5L.
I'd really appreciate it. Thanks!

Thank you very much.
What is the easiest method I should follow to find NNP?

Hi,
I haven't shot panorama using NN5L in a few years and never with Nikon 10.5. How many shots around on DX camera and what angles do I shoot to get 360 pano.
Thank you!

Nikon 10.5 on Nikon DX (cropped) sensor body?

I use one of two shooting patterns:

1. Outdoors and in larger interiors: 6-around at about -10/-15 degrees (so that just the outer edge of the rotator is in the bottom of the frame), plus one or more 'zenith' shots at approx. +65 as this is more likely to provid a good link(s) to the main row that a +90 zenith. It's up to you how you deal with the nadir 'hole', do you have a Nadir adapter for your NN5L?

2. In smaller more confined interiors - 6-around as above plus a second row of 6-around at about +50. I know it sounds odd but it seems to work for me for such scenes.

BTW I do have Nadir adapter. I forgot how to use it also.

Hi,
Is there a way in autopano pro to limit number of control points? How?
Thanks!

Hi,
This nuts!
I can do better handheld than this pano on NN5. What's wrong? Please!
Thanks!

70 control points is hardly any for a whole panorama.

In what way do you wish/need to 'manage' CPs anyway?

A well shot pano should seldom require much if any CP editing.

Here's a pano shot with a Nikon 10.5mm FE on a Nikon DX body.

A main row of 6-around plus 'zenith' and APG found over 1,000 CPs.

What do you think is wrong with this - other than the obvious issue with the overhead wires, and lack of zenith area.

I meant 70 points for each image.
I've no idea why flag post and house are not stitching correctly. I spend whole gay shooting yesterday.
Thanks!

70 points for each image is not a lot with the CP detection system used by APP/APG.

It would be a lot if you were placing each CP manually in, say, PTGui; but APP/APG doesn't 'work' like that.

If you wished to share a reduced size version of the image set in JPEG format - dropbox is a good way to share files - I would be happy to take a look and see what I might be going on.

Meanwhile perhaps you would like to show us a screenshot from the CP editor - like that I posted - it may give us a clue.

...............

The flag is relatively close to the camera - the stitch issue here may indicate that your camera/lens is not set at the NPP? How confident are you that it is?

I think you may have to send an invitation via email for me to access?

I'll send you a PM via the forum with my email address.

OK - I received 7 images two of which seem to be the same.

1. The flagpole doesn't stitch properly because it is moving in the wind - see screenshot 1. This can be fixed using the mask tool.

2. Regarding the house - there's something odd about the two images that overlap over the house, it's as if the tripod moved or something, they just don't align well at all - see screenshots 2 and 3.

3. You appear to have used auto white balance and auto focus this will not help the CP detection system.

4. This is a 'tricky' scene for auto CP detection - a combination of large areas of relatively featureless road surface and a lot of foliage that's moving in the wind, I guess the clouds are moving too.

5. More consideration of where the seams/overlaps will occur might have made stitching easier.

Thank you so much for your help.
So, it's not Npp errors?
I'll try again soon and let you know. What kind of balance I should use, if not AWB. I'll use manual focus next time.

Hi,
Here is another shot at pano with 10.5. I know exposure is bad, etc., but stitching looks good to me. Even wires are okay.
What you think? I think NPP is good now.
Thanks!

Looks good at this size.

Wires are always challenging/tricky.

I wonder why the roof of the house near centre is not level.

Was your pano head levelled?

Any NPP parallax issues are more likely to be exposed shooting small interiors.
