| Technic of the Sequential Photography, Part 1 | ||||||||
| Early November 2002 I started the first sequence of images for the 'Day&Night'-series. At this time I used the 5-mega-pixel digital camera Olympus E 20P with a tripod and tripod head from Swarovski. The zoom lens together with the tele converter is adjusted to a focal length of 180 mm - compared to a 35 mm-camera. The horizontal and vertical overlapping from image to image is about 15%. To achieve the best possible transport from image to image and line to line I equipped the tripod head with precise graduated indicating.
Dependent on the size of the motive I make 25 up to 117 images per picture. The next step is a index print on paper with the image number as a subtitle. After cutting the index images, they will be sorted and pasted. The picture above shows such a work out of pasted index images. Especially if you want to try some alternative images to fit best, this technic of hand-mounting is a very good way. And you get a good idea of the impression of the final picture. The last step before starting the computer is to write down the numbers of the images onto a grid and to determine the vertical and horizontal centre lines. The eye-level I call the horizontal centre line and the middle of this line crosses with the vertical centre-line. When I started in December 2002 to compose the first pictures, I used WindowsXP and a Athlon processor on the main board with 1.5 GigaByte of ram. The only software I used was PhotoShop 7.0. Most of the professional photographers are familiar with this program and therefore I give a summary of my work in PhotoShop only. |
After calculating the size of the work-surface, the vertical and horizontal blue centre lines are set. The composing starts at the intersection and goes from there to the top, the bottom, the left and to the right. A precise alignment is important.
A big advantage of PhotoShop is the easy work with 'levels' and the 'free transformation' tool. It took me some time, but after composing some 15.000 images, I know how to deal with it. After the correct image alignment the transparency has to be set to 60%. The next image with 40% transparency will be moved on top of the first image to fit it. Using the 'free transformation' tool one can do a perfect 'stitching'. To do it even better the last image is cut with a free hand tool and a soft edge of 15 to 40 pixel. Increase the transparency of both images to 100% and test the correctness of color and brightness. Do not open more than 15 levels. |
