More from Albert

My first real non P365 blog entry since I started it :) But more photos! These are a few more panoramas from the Albert Nicholas Gardens yesterday which I stitched today.

First, here's a link to another interactive spherical panorama, but this one is different in an important way. This is the first "high dynamic range" (HDR) panorama I've tried. 30 second HDR tutorial: Cameras cannot capture detail in the whole range of brightness levels in a scene, and as a result highlights and shadows get 'blown out'. One way to get around this problem is to take a series shots (3 in this case) exposed correctly for highlights, midtones and shadows, and then merge them to get the best of each. This is tricky when panoramas need 6 shots anyway, so a HDR pano takes 18 photos, all which need to be stitched and merged.

The result, however, is worth the effort I think. When you have a look, notice how you can see a reasonable amount of detail in both the darkest and lightest areas:

Here's three more "flat" panoramas. Make sure you ckick on the images below to see them properly!
