Caffenolcolor: March 2015
http://caffenolcolor.blogspot.com/2015_03_01_archive.html
Film photography. Optical, mechanical, chemical and other experiments. Thursday, March 26, 2015. But the metal of the round tin box is thick what will restrict very much the image circle. So I made a larger hole, 4mm diameter, and glued over this hole and inside the box a thin film of acetate with aluminium tape and then perforated this film and aluminium adhesive together with the 0,5 mm pin at the middle of the 4 mm hole. First version of my pinhole camera. Pinhole photo inverted with Photoscape.

Caffenolcolor: Split C-41 developer at room temperature
http://caffenolcolor.blogspot.com/2015/04/split-c-41-developer-at-room-temperature.html
Film photography. Optical, mechanical, chemical and other experiments. Thursday, April 23, 2015. Split C-41 developer at room temperature. Since a while I have been using Dignan's 2-bath C-41 developer. The color restitution depends more on the second bath, so I have been experimenting different solutions, and these are the results for a 5% solution of Potassium Carbonate anhydrous with 4g/liter of Sodium Chloride, table salt. The film I used was Fuji Superia 100, expired in 2002. Posted by Henrique Sousa.

Film photography. Optical, mechanical, chemical and other experiments. Sunday, February 22, 2015. Always learning something new. I have been getting these terrible surge marks on my B&W pictures.

Caffenolcolor: Interesting reactions
http://caffenolcolor.blogspot.com/p/interesting-reactions.html
Film photography. Optical, mechanical, chemical and other experiments. Sodium sulfite can be prepared. By reacting sodium carbonate with sulfurous acid:. Na2CO3 H2SO3 → Na2SO3 CO2 H2O. By reacting sodium hydroxide with sulfur dioxide gas:. 2 NaOH SO2 → Na2SO3 H2O. By reacting metabisulfite with sodium hydroxide. Na2S2O5 2NaOH - 2Na2SO3 H2O. Sodium Thiosulfate may be prepared, can be read here for instance*. By boiling a solution of sodium sulfite with Sulfur. Na2SO3 1/8 S8 → Na2S2O3. Can the reaction bet...

Film photography. Optical, mechanical, chemical and other experiments. Wednesday, April 1, 2015. 3 Great Free Software Programs to treat your photos. I have been looking for free software to treat my photos. The first I discovered was GIMP, The GNU Image Manipulation Program. I am still using it and there are additional plugins that may be added to the program, it is very good indeed but not for beginners. That has the essential tools to enhance the quality of scanned film pictures. And GIMP to spread so...
