I am going to use my Yashica camera for taking photos- mostly outdoor photography..Which film roll would be best suited: 100, 200 or 400? Is there any difference in selection of film rolls for outdoor and indoor photography?

You can use them all for outdoor and flash photography. 100 ISO should give you the least grain when enlarged. Indoor film usually has a "T" in its name referring to tungsten light (except for T-Max which is a black and white film).

The only time you need to worry about indoor and outdoor film is when using colour slide film. This comes in either 'outdoor' or 'indoor' varieties (if you can still get the latter). If you use outdoor film indoors without a filter, or daylight balanced lighting, you will get an orange colour cast. With modern film you can happily use 400 ISO rated film.

My choice of film usually depends on what I plan on photographing. For outdoors on a sunny day its usually Kodak Portra ISO 160 VC (Vivid Color). If its overcast or I'm somewhere that I'll be inside occasionally like at a state park with restored log cabins or maybe trying some macro back in the wooded areas or I know I'll be using my 300mm a lot I'll load Fuji PRO 400H or Portra ISO 400 VC. When I know most everything will be done using a flash I choose Portra 160 NC (Natural Color). For black and white its usually Ilford XP2 Super, ISO 400.

It's easy to choose once you understand the ISO ratings that you ask about. The higher the ISO the more sensitive the film is to light. So if you are inside in lower light areas, a higher ISO (400 or higher) film would be best. If you are outside on a bright day, the lower ISO rating (100) would be best. But there is a trade off. The higher the ISO, the more grain there is on the film. So you need to choose with care. Happy Shooting! Bill
