    When I first studied B&W (black and white) photography, I knew that one set the proper exposure either by using a spot meter (I used a special one) to select what looked like 18% gray or else measured exposure using an 18% gray card (which I often did): en.wikipedia.org/wiki/Gray_card&nb sp;Will
open in a new tab or window So, in this collection of hand-held photos, I first set the shutter speed to 1/60 second, which is good since the Nikkor lens is a VR (vibration reduction) lens and pointed the camera south towards Alice Pratt Brown Hall and fiddled with the f-stop (fine tuning it to 18% gray) until I found something I was happy with and that turned out to be f/16, which gave me great depth of field. If I do this correctly, then the sun, and reflections will look to be close to natural as they are in this panorama (in other words, if done correctly, everything else falls into place). Note: in the *Keck Hall: Winter Light and Golden Brick* GigaPan (www.gigapan.org/gigapans/40583/ ), I missed the exposure a bit, and adjusted it using some Nikon software and the result is *Keck Hall: Winter Light* Gigapan (www.gigapan.org/gigapans/42462/ ), which looks good but not as dramatic as the unaltered GigaPan. Proper exposure can be very difficult to attain.

    What prompted my question is that according to the stitcher notes all the images were taken at the same exposure (as is normal of course) but I would have thought that if you expsoure was set so that the sky near the sun wasn't completely blown out (as it is not) then some of the foreground would be nearly black which isn't the case. So I was wondering if you had brightened the foreground, but it would seem not. Interesting.

    I'm pleased with this panorama and have created a on-going series of fountain panoramas taken in the Houston area: www.gigapan.org/gigapans/most_popul ar/?q=houstonfountain Regarding your question, in all my panoramas, there are only three that I have had to apply an exposure correction to, and this is not one of them ... just natural Texas light is all that I used and *no* correction. I always look for unique natural light effects as demonstrated in this GigaPan: www.gigapan.org/gigapans/42462/snap shots/120943/ Why do you ask about processing the images?

    Nice shot! Did you have to process the original images to brighten the ground?
