Theme
I've chosen this panorama because I really like the light and it reminds me of a very nice trip to Ljubljana. It shows Planinska jama (The Planina cave) which is one of the longest Slovenian water caves.I was able to visit this cave at the annual PanoTools-Meeting 2015. Thanks again to Boštjan Burger for organising and hosting the meeting. Be sure to check out Boštjans contribution to the WWP event water, which shows the same cave.
Making Of
As the lens is a fisheye lens, four pictures easily cover 360°. To capture the large dynamic range of the scenery I took three exposures in each direction. I used a custom lens bracket on a tripod. The exposures were 2 f-stops apart. The exposures were blended in Lightroom and exported to be stitched with PTGui Pro. Zenith and nadir were retouched by hand in Photoshop.- Camera: Sony ILCE-6000
- Lens: Samyang 7mm/3.5 UMC fisheye @ f7.1(lens hood shaved, MFT lens adapted for Sony E-mount)
- Mounting: Custom-made lens bracket mounted on top of a tripod
- Software: PTGui Pro, Smartblend, Photoshop CC, Pano2VR
- Images: 4 pictures @ 90° (each image was rendered from 3 bracketed exposures before stitching)
- Exposure: 0.4 seconds, 1.6 seconds and 6 seconds @ ISO 100
