Leon Warnerke was a Polish engineer and inventor in the field of photography, independence activist and revolutionary. Leon Warnerke was a pseudonym; his real name was Władysław Małachowski.
These are the 3 most common film speed formats that you would most likely run into (mainly when picking film stocks). What are the differences? Why do they all exist? And how do we convert between them?

Film speed | Wikipedia audio article
This is an audio version of the Wikipedia Article:
Film speed
Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.
Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain
Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

Focus 45: Not Just Cameras
The Eastman Museum's technology collection holds more than 17,000 objects from the earliest days of photography to today’s digital devices. While the collection is well known for its French and American cameras, the collection is also home to rare papers, film, packaging supplies, manuals, and early objects related to developing and printing. Collection Manager Erin Fisher will discuss some of the hidden gems of the collection.

SUMMARY
=======
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras.
Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.
