Editorial
The photos on theses pages were created with an Olympus C-5060WZ camera and an Olympus FS-FL50 flash, and processed with Paint Shop Pro 7. The large distances and dim lighting conditions, particularly in the lecture halls, put a severe challenge on the camera's auto-focus which was exacerbated by the rather dynamic behavior of some speakers. In addition, I had to resort to digital zoom in many cases to get close-up shots of speakers. Therefore, I have to apologize for some of the pictures being not optimally focused and/or grainy, which, in addition to the effects of digital zoom, was also caused by the inevitable under-exposure if the objects were beyond the flash's working range (which was the case more often than not). Unfortunately, the automatic flash operation, which employs a few pre-flashes to set the proper exposure and white balance, causes a delay of a few tenths of a second between pressing the shutter button and the actual exposure; a time long enough for some people to move more or less out of the image area...
Both issues, the auto-focus problem and the exposure delay, might have been overcome by using manual focus and manual flash operation, respectively. However, under the conditions given, I decided to stick to the automatic modes since they improved the chance of getting reasonably well focused and exposed images even if the distance to the object changed quite significantly from one picture to the next.
Copyright: Although I hold the copyright to all photos on these pages you are free to use them if you want to. I would appreciate to be credited, though, at least for the nice pictures. (You need not credit me for the less beautiful ones ;-) .)
In any case, I will be happy if you like my photos, and I hope you don't blame me too much if I did not get you from your most beautiful side. (There was that delay between pressing the shutter and the exposure; and, anyway, I have put on these pages only 193 of a total of 270 technically acceptable pictures because I had my doubts that you might have liked the remaining 77 ones.)
