My wish is to share my experience on topics that I think usefull to those who stitch panoramas from photographies for pleasure or for a living.

Foreword: while being widely used by many, the word "Nodal Point" happens to be not correct in the meaning that is intended here. Entrance Pupil or NPP (i.e. "No Parallax Point") should have been used -in most cases- instead of Nodal Point

1. Locate the nodal point of a fisheye lens.

Nodal point of the SIGMA 8mm f:4 EX FishEye.

2. Get the best accuracy from your Pano-head.

3. Get started in PanoraMacrophotography.

4. Let's put our camera on the pole position...

5. How to better insert the Nadir shot.

6. Probably the slimmest indented rotator for a panorama head

7. How to make a pano from only three slanted shots with the Sigma 8mm on a monopode (to be translated soon from French)

8. Entertainment: "Monster Garage" could have made this weird looking panohead

9. Impossible challenge: To make and render a complete 360x180deg perfect panorama with only three photos and Realviz's Stitcher 4

10. An accurate but home-made Spherical Panorama Head.

11. Smart-Crop your source images to get sharper Panorama: Tutorial.

12. A little Quiz and some do-it-yourself experiment.

13. Comparison between two panographer's fisheye lenses: Sigma 8mm Vs Nikkor 10.5mm

14. Work around the lack of aperture ring on the Nikkor 10.5mm lens when it is adapted to a Canon EOS camera.

15. Automatic Stitching: a short report on comparison testing of Stitcher 5.5 Unlimited and PTGui 5.8

16. Another (no very scientific) blending applications comparison study.

17. Auto-stitching of two hemispherical images: three S/W Comparison test.

18-a. Test results preview of the Tokina 10 -17mm fisheye zoom lens and an intricate panorama making with it. "How to" for a clean shave of the sun shade.

18-b. Comparison of intricate panorama making with one FF camera (EOS 5D2) and two fisheye zoom lenses (Tokina 10-17 mm and Canon 8-15 mm); AutoPano Giga and PTGui Pro were used to complete the comparison.

19. Study of the influence of light wavelength on Chromatic Aberration (C.A.) for fisheye images + comparison of TCA on different fisheye lenses. A detailed study of C.A. on a special case (Nikkor 10.5 mm fisheye + Canon EOS 5D).

20. Lateral Color a.k.a. Transverse Color Aberration (TCA) myth and reality.

21. Three different Flash editor / players for panorama publication

22. Plea for Double-Shot rehabilitation

23. Very short focal Fisheye lenses and Stitching/Blending Double-Shot (DS) images (3 parts article)

24. One-Shot cheap solution?

25. What's the possible ultimate image quality of a panorama made with 2-shots?

26. What is the minimum Angle of View required from the circular image to make 2-shots?

26. Some panoramas shot in very tight places: In the kitchen, the tureen . More to come...

27. Put an easel on your giant pole to help shooting steady a subject at close range.

28. Review of the new Samyang 8 mm fisheye lens (aka Polar 8 mm, Bower 8 mm, Vivitar 7 mm, Falcon 8 mm, etc.)

29. The No-Parallax Point theory is not applicable to fisheye lenses: a Least-Parallax Point (LPP) theory is therefore introduced.

30.The limit line between stitched images of a blended panorama may be not where one thinks them to be.

31. The shape of the in-focus zone for fisheyes is drawn on a color coded 2D map.

32. Possibly the fastest way to set the LPP with a Laser Level or with a Laser Pointer.

32. Five blenders facing a single (oddly exposed) image.

33. Adjusting the location of the vertical arm of the panohead (the camera being switched-off)!

34. A short page about the new extremely wide-angle Samyang 14 mm standard lens.

35. The Entrance Pupil moves also in standard lenses as well...

36. To make full panorama of very high Image Quality with a rectilinear lens and only 8-9 shots!
