Here you can find some examples of one of my favourite hobbies: photographing. The pics on these sites are a factor 4 smaller than the images scanned. This is partialy for saving transfer time (the larges images are more than 2 MBytes in size), and partily for saving space on my home page (T-Online allows only 10 MBytes of web space).

Images in Bits & Bytes

The images were taken mostly with an EOS 5 SLR body and two lenses with 28-105mm and 75-300mm zoom range. The normal zoom lens is of the high-quality series from Canon with internal focus and ultrasonic motor (USM). The tele zoom is of the low budget series from Canon and pre-USM, its focus is driven by an ordinary micro motor. But in image quality it is useful, at least at an opening less than 1/8. Since start of the year 2001, I have exchanged these two lenses with an EF 28-135 IS USM and an EF 75-300 IS USM, and I also got an EOS IX SLR body, which uses the more modern APS image format. A digital chassis like the D-30 would be fine, but in the moment it is a little bit expensive (~3000 Euro) and has a image size smaller than the APS, which means that an other zoom lens with 17-35 mm would be required to fit to the camera and deliver a wide angle to normal lens zoom range. Togeter with other useful extras for such a digital camera, I would have to spend some 5000 Euro in my photo equipment, and that is a little bit too much for me in the moment - in addition, the CanoScan FS 2710 I use produces more than three times as much pixels per 35mm image as the EOS D30 does from a shot (probably next year Canon will sell a 5 megapixel chassis for the same money the D-30 costs and the D-30 will be available for half the price).

The pictures on this web site have been generated by different means: Some of the older ones have been scanned from a print by a flatbed scanner. This delivered a relatively poor quality, because the scanner used was one of the cheaper ones. Since summer 2000 I own a film- and slide scanner from Canon, which scans slides and negatives with up to 2720 dpi resolution. This results in a far better quality. The pictures taken with this scanner have been scanned with maximum resulution, for presentation they have been scaled down to 340 and 680 dpi.

For the view on the web pages the smaler images have been used, by taking a relatively good compression ratio, the images are only 10 to 20 kBytes in size - they load within some seconds. These images have been taken as a link to the larger pictures, saved with a smaller compression rate and being double the size of the smaller images. They are between 30 and 120 kBytes in size, but they have by far more details to be viewed.
