This is what it looks like when day and night meet in a single image. Including the prep time, it took photographer Chris Kotsiopoloulos thirty hours to capture the hundreds photos needed to stitch this together. The shot was taken in Sounio, Greece. It got so cold at times that he had to use a hairdryer to keep the lens from fogging up. See the full post for more details!
This image has captions, and will give you a little more information about each sequence:
And here's Kotsiopoloulos in his own words -
"I started taking photos with the camera on a tripod facing east "The 'day part' is composed of a dozen of shots covering the landscape from east to west and the Sun's course from sunrise to sunset. The Sun's position was recorded exactly every 15 minutes using an intervalometer, with an astrosolar filter adjusted to the camera lens. In one of the shots, when the Sun was near it's maximum altitude, I removed the filter in order to capture a more 'dramatic' shot with the Sun's glare.
After the sunset, I took various shots with the camera facing west - northwest in order to achieve a more smooth transition from the 'day part' to the 'night part' of the picture. The 'night part' is also composed of a dozen of shots covering the landscape from west to east.
After the 'transition' shots I mentioned above, I took a small startrail sequence, with approximately half an hour duration, and the camera facing northwest. Then at 19.13 local time, I turned the camera to north and I started taking the all-night startrail which lasted almost 11 hours. After the 11 hour startrail I turned the camera to northeast and I shot a half an hour startrail, and finally with the camera at northeast and east some 'night to day' transition shots."
