Potted plant – Chrysanteme – Macro pano

Last Sunday I did a pano of a potted chrysanteme plant. The pano covers a FOV 60″ x 40″ and it is a planar pano with 9 x 4 image positions. The challenge was the use of a 85mm lens and to get the lens only 40cm in distance to the plant. Finally it needed 1188 images to get this pano!

How ti works: To reduce the focus point (despite the usage of f8) I had to use a 13mm distance tube between lens and camerabody. In consequence the focus distance is very small. To get one sharp image which is sharp in front to rear I had to take 11 images on each position each set with different distance. I used the distance units printed on the lens: 1.0m, 1.2m, 1.5m, 1.7m, 2m, 2.5m, 3m, 4m, 7m, 15m and infinity. And finally to raise the hyper dynamic range of the images (and to reduce differences between shadow and light parts) I took each of the above mentioned images with 3 different exposures: 1/1000s, 1/100s and 1/10s. So in total to take the 9 x 4 x 11 x 3 = 1188 images (crop 1.6) it took from 10:59 – 14:56 on sunday. To reduce the manual work of taking hundrets of images I used my merlin pano head (pattern & pano head driven by the T&C handcontroller and the HDR part was done by the promote control device – I used a step of 3.3 EV). I did shoot eleven panos with different distance values. The 3 HDR bracketed images got fused with phtomatix pro and 11 focus images got focus stacked by zerene stacker. The finally 36 images got stiched with autopano giga and the tour was created by panotour pro. The final pano is around 250 megapixel (17982 * 14591 pixsel) in size and has a filesize of 600mb (tiff 16bit). The tour online is 90mb (jpeg) in size.

Festung Hohensalzburg / Schloss Freisaal

On September 13, 2011 I took a pano looking from South of Salzburg in direction Festung Hohensalzburg. The pano covers 190 degree and shows the Festung, Schloss Freisaal and also the Stift Nonnberg. The bike and Joggers way passing the Schloss Freisaal is the Freisaalweg. Behind the pano on the other side of the roas the Freisaalweg is changing to the Hellbrunner Allee an around 2500m long Joggers paradise ;-)

The pano is made of 270 images, on each imageposition 5 brackets, 27 image positions on each of two rows. I used a focal length of 85mm and used aperture f8. The final pano has an size of 298 megapixel. I fuesd and stiched the images with autopano giga and the tour was made with panotour pro. The google maps radar is not working correctly, I think because of a non-spherical pano format.

The pano does contain many stiching errors (I did not optimize a lot) and also fusing brakcet images of buildings does work very well but trees will result in bad image quality (finally zooming into max. you can see it…)
