The criterion, basic roll of movie Testament be rated with ISO 100, nevertheless movie ratings reach from ISO 25 to ISO 1600. The higher the movie rush, the less magnitude of fluorescent you Testament devoir to expose it. The lower the movie rush, the longer proportions of duration or better vastness of luminous you Testament commitment. On the contrary, luminosity is not the one episode to take into consideration when choosing a film speed. Here are a few tips.
Instructions
1. Decide what artistic or technical effect you want to achieve with your photographs. If technically perfect photographs with small, unnoticeable grain are important to you, the slower your film speed the better. If you want to achieve a more grainy effect the faster your film’s speed, the grainier it will be. The reason faster films have grainy appearance is because larger grains in the film have a greater sensitivity to light.
Assess your photographic environment and subject matter. Are you shooting outside during bright daylight or at dusk? Are you shooting inside with lights or on a tripod? All of these elements must come into consideration when choosing a film speed. Shooting outside in bright midday daylight will only require a film with an ISO 100, while if you are shooting inside and you do not have access to additional light sources or a tripod, you will want to consider a faster film speed film such as 400.2.
3. Know your equipment. If you are shooting in a low light situation where the lighting is out of your control, such as at an indoor event where use of a flash is inappropriate, you should definitely use a tripod. In addition to the tripod, plan to use a higher number, faster speed film such as one with ISO 800.
4. Understand your processing ability. If you intend to process the film yourself make sure you read the chemical and temperature requirements provided with the film. Some brands and speeds require exact timing, precise temperature and no room for error, while other films are more forgiving, meaning your temperatures and timing can be slightly off.
