Features & Capabilities

The Art of Foto project was established in 2011 and adheres to the analogue black and white photography. Our application helps users working with large-format cameras as well as other film cameras:

  1. Time calculator To perform operations with time, what helps when developing films using The Zone System and sensiometry with compensation for contraction development (known as N-) and expansion development ((known as N+), using large-format cameras etc.

  2. Bellows extension Exposure compensation calculator based on bellows extension.

  3. Conversion 35 mm Conversion focal length of the medium and all famous large format cameras lenses into the 35 mm format.

  4. Calculator of developer Calculator of developer and water proportions for High concentrate film developers such as pyro.

  5. Reciprocity Calculation of exposure, taking into account the influence of the Schwarzschild effect.

  6. Negative camera Camera for viewing black and white and color negatives in real time.

  7. Viewfinder For film shoots, especially large format. Now you can evaluate a possible frame without taking out the your camera, determine which lens is more suitable for a given scene, see the frame in black and white and in color. All major film formats are available, the non-film part of the screen can be made hidden, and of course, you can take a photo that will be saved in the gallery. One can zoom using fingers, on devices with several cameras, switching occurs automatically. Focal lengths are switched by tapping on the current focal length indicator (upper right corner), formats - by tapping on the format indicator in the upper left corner of the screen.

  8. Process Timer

Timer for the manure and printing of photographs. Light radiated by the device can lead to light, reduce the brightness of the screen to a minimum and be sure to test photosensitive materials before use.

  1. Light Table

A light table for viewing transparent materials on the lumen, for example, films for evaluating the quality of the manure, when there is no more professional device at hand.

  1. Exposure Meter

Measurement of exposure based on data from the device camera.

  1. Spot Meter

Pointed light frozen (exposure in the reflected light).

按了拍照没办法存图,只能截图吗?

I use this app all the time to calculate the bellows extension factor of my large format camera. It is super easy to use! I often do long exposures so the reciprocity tool is equally as useful. I just wish I could edit them or add custom films - some film stocks reciprocity times seem different than the film’s data sheet (but still close - like Ilford Ortho).

I stumble upon this app after seeing a video on YouTube about the Bellows extension. I shoot Hasselbald V 6x6, Hasselblad Xpan, Rolleiflex TLR, 6x9 on my Large Format, 4x5, 8x10 and the calculations are Dead On. Makes adjusting for reciprocity Failure a very simple task. Same for Bellows Extension on any of my cameras and it has and easy lens conversion from all the popular formats back to the 35mm angle of View. On top of that they have a Developer measurement calculator for the darkroom. It’s really simple and well thought. A must have if you are serious about film photography or just starting into this realm. It’s a joy to use.
