Thanks Matt.
A few more questions, what speed of film is best for beginners? Does it matter?
What is a good cheap B&W film? Any rule about exposure on B&W film?
Speed: depends on what conditions you photograph under. Generally anything between 100 ISO and 400 ISO should be fine for most purposes.
B & W exposure: same rules as for colour, except sometimes the colour of the light can be important with colour exposures (think street lights or tungsten bulbs).
B & W film choice: don't try to save too much money

. I'd suggest to any beginner that they start out with a widely available film from one of the three top quality manufacturers who continue to make film today - Kodak, Ilford or Fuji. There are good films available from other manufacturers but there are more questions concerning quality control issues or supply chain issues - something a beginner shouldn't really try to deal with until they are more experienced.
In my case, I'm a lifelong Kodak user. For me currently, that means Plus-X for ISO 125, and TMY-2 for 400 ISO.
I'm not sure, however, that Plus-X is going to be around for the long haul

.
In the short term though, Freestyle Photo has a house brand (Arista Premium) for 35mm film that most likely is actually Kodak film - a 100 ISO version of Plus-X, and for 400 ISO, a version of Tri-X:

Those prices are excellent, and Tri-X (and Plus-X

) are classic choices that you cannot go wrong with.
