Isn't fillm ASA speed. It does add noise if you use the fastest film. Like ASA 800 or 1600. David
ASA and ISO are the same thing. They are just different national standards.
NO NOISE on film at any speed. Noise is digital artifacts/
As film ASA/ISO goes up the crystal grains in the film are bigger. Bigger grains of crystal in film accept the light faster.
Therefore fast film shows grain more than slow film...
Slow film with incredible smoothness was Kodak 25 ASA.
Film at 1600 is about as high as film went. People often pushed 1600 to 3200. At that level film was often considered forensic for low light (spying on criminals and in the military for espionage).
Faster film is, as mentioned more expensive, but I buy my film dated and expired on eBay and the price of film is very reasonable.
I don't often have trouble with color shift and never with black and white, by buying only from eBay sellers who refrigerate the film.
I have often used 15 to 20 year expired film if it is refrigerated by those good sellers.
I have a freezer full of Medium Format and Large Format film that is from current to 15 year expired. I expect never to have any problem with that film, as I bought it refrigerated and it went into my film freezer when I purchased it.
I process film using the caffenol process, with the cheapest instant coffee, vitamin C, and Washing Soda that can be bought. Furthermore it is readily available at the grocery store, the pharmacy, and swimming pool supply houses. Use Folgers Instant.
Those who think film is dead, or expensive are missing the boat on fun and creativity.
Another MYTH is that you need a darkroom. Sorry folks, but daylight processing tanks have been around for many years. I have never had a darkroom and I process film DIY. You need a small dark space to put the film in tanks (sheet film) or on rolls in round tanks (35mm or 120 roll film)
Not having a darkroom has not been an valid excuse for not processing your own film for many years.
