A simple CO2 sensor is often not enough for precise monitoring of indoor air quality. In this project I show the construction of a fully dynamic air quality monitor based on ESPHome. The special feature: The system can be completely re-flashed at runtime via...
This WIFI to Ethernet bridge based on the WT32-ETH01 module is ideal for cameras.
This article is about the development of ORWO UT-18 in the negative process as an alternative to ORWO C-9165.
This article is about the development of ORWO reversal films, here the UT-18, in currently available photo chemistry as an alternative to ORWO C-9165, which is based on CD-1. Chemical basis of dye formation in ORWO processes (e.g. C-9165) The essential difference between the...
Today we are devoting ourselves to research and understanding analog film processes. A particularly fascinating project is the development of the Kodak 5251 50t Eastman Color Negative Film - a historical film from the 1960s, which originally for the now outdated ...
The NP 3 is a very fine-grain recording material of medium sensitivity for outdoor recordings. The remarkable sharpness of contours and the high resolving power offer favorable conditions, e.g. for rear projection recordings. A short drying time is guaranteed by high hardening. To increase the antihalation protection, the...
As a standard material for indoor and outdoor recordings at high sensitivity, the NP 5 is characterized by outstanding image sharpness and low graininess. Thanks to these properties, it particularly meets the requirements that large-scale projection (wide screen, total vision, etc.) places on the recording material...
Highest sensitivity. For current film reports, especially for artificial light in the theater, at meetings, etc., but also for daylight under unfavorable lighting conditions. The base is colored grey. Format 70 mm, 35 mm and 16 mm code no. 84— at 70mm, 35...
PC 9 is a multilayer film consisting of three emulsion layers selectively sensitive to green, red and blue light. The two upper emulsion layers are stained with screen dyes to avoid diffusion halos. On the back of the film is a green antihalation layer...
PC 7 is a multilayer film consisting of three emulsion layers selectively sensitive to blue, green and red light. A yellow filter dye is embedded in the top layer to shield blue rays from the middle and bottom layers. On...
