Technical details how the pictures were scanned and stored in Archives

Color pictures were taken by Pentax K-1000 camera with SMC Pentax-M 1:2 50 mm, Phase 2 CCT (?) 1:4 70-200 mm, and JCPenney 1:2.8 28 mm lenses. Black and white pictures were taken by a Russian camera Zenith E.

The pictures were scanned from 4 x 6 or 3.5 x 5 color prints with 150 DPI resolution and with sharpening filter. Resulting images have size approximately 880 x 580 x 16 Million (from 4 x 6 prints) or 840 x 510 x 16 Million (from 3.5 x 5 prints). The images were saved in JPEG format with medium quality option (3, using Photo Shop on Mac or 6 on PC). They occupy 100 KB in average (between 60 and 300 KB).

After March of 2003, pictures are taken by a digital camera Nikon D100 with Nikon 24-85mm/1:3.5-4.5 G EDIF AFS Nikkor Zoom lens. After February of 2004, some of pictures are taken by a long-focus lens Nikkor AF 70 - 300mm 1:4-5.6D ED. After September of 2005, some of pictures are taken by a wide angle lens Sigma 15-30mm f/3.5-4.5 DG. After March of 2008, some of pictures are taken by a macro lens Sigma 105mm f/2.8D DG Macro. After January of 2009, some of pictures are taken by a lens Nikon AF Nikkor 24-85mm 1:2.8-4 D, while 24-85mm/1:3.5-4.5 G is no longer used. After 2009, some of pictures may be taken by a lens Sigma AF Super Wide 24mm 1:2.8. After 2005, some pictures were taken with a flash "Nikon Speedlight SB-50DX". After 2009, some pictures were taken with a flash "Sigma EM-140 DG Ring Flash". After August 5, 2010 the camera was upgraded to D300. Images are uploaded with 38.4% size reduction (1155x768 image size), 300/0.2/0 unsharp mask, and "Save for web"-(40-60) options. Average file size is around 200 KB.

Pictures are stored in directories 1-333 corresponding to the total number of developed rolls of film (rolls were numbered in chronological order). Digital pictures are grouped in directories with numbers 334 and larger, mostly 26 pictures in each directory.

Reduced-size slides were created from original images by executing Mathematica program. (it crops original images to square, resizes them to 360x360 pixels and surrounds by a frame). Pictures were indexed by another Mathematica program. For each slide, a HTML-document was created by means of a Mathematica program (it scans directories, extracts picture captions and composes individual HTML-documents with linked pictures). Captions are stored in captions.txt data files. Links were inserted automatically from links.txt data file (the list of links can be viewed). Background color hue was set to an average hue of the picture, luminosity was set to 1/4, and saturation to square root of saturation of the picture. For more maintenance programs, see this directory.

Relatively few pictures were selected, saved into a separate directory (with higher compression), and were provided with captions. Technical details how the pictures were selected and stored are available too.

Image viewer for full size pictures was copied from "Web Gallery of Art" web page.
