Fast film
Film with an emulsion that is very sensitive to light. Such films have high ISO ratings (i.e.: ISO1600). They are all, however, more grainy than there slower counterparts.
(see Grain & ISO) ...
FAST FILM - High speed film, i.e. film that is more sensitive to light, meaning less light is needed to obtain a properly-exposed image.
3. Use fast film or a fast ISO setting on a digital camera when taking baseball photos.
Why fast film? Because animals often move - and they can move pretty fast in the zoo as well as the wild. You usually don't want to blur your subject.
Very fast film (such as ISO 1000) may be used without a flash even in low light conditions, although the prints may look grainy. In low light conditions with a slower film speed, it is necessary to use a flash for correct exposure.
It is common for fast film to have larger grain size and poorer rendering of colours (or grey scale) than slow film.
The advantages of fast film are obvious. You can use them at lower light levels without flash, you can get faster shutter speeds, particularly with longer telephoto lenses, and so on. So why use slower film at all?
FAST FILM-Photographic material of relatively high sensitivity to light, having a high-exposure index. (PIA) FIELD-Scanning lines in one half of one video or television frame. There are two fields (one odd, one even) in a frame. One field equals 262.
I use fast film exclusively for concert shooting
Fuji Superia X-TRA 800: Grain is really fine with this film. I really have no complaints.
Modern lenses and current fast films are so good that professional results can be obtained with less expensive zooms that can rival top of the line professional lenses.
Fast films are useful indoors or in low-light conditions where a flash is not available or allowed, such as in museums where non-flash photography is permitted.
I'll be the first to admit I'm not a big fan of fast films. I prefer fine grain and high resolution, which films with higher ISO emulsions give up in pursuit of speed.
Slow films will have finer grain than fast film however slow films by their very nature may involve using shutter speeds which are to slow for the intended purpose.
If you use film, choose a fast film speed (800 at least) for action shots. If you want to get details of birds at rest, you can choose a film speed that's slower.
Fast film has a coarser grain (and hence lower definition), lower contrast, but more latitude. Film speed is determined by the minimum exposure required to change the silver in the film emulsion to a latent image.
However, photographers shooting in darker scenes with poor lighting situations should opt for fast film that renders a grainer printed photo.
With a film camera, use a fast film; 400 or 800 ASA will work well inside many homes when 100 ASA would require a flash. If you are using a digital camera, read the manual. The more advanced digitals will let you set the ISO equivalent speed.
Consider using fast film or setting your digital SLR on a fast ISO setting. Keep your body and the camera as steady as possible, track the subject through the viewfinder and ensure your camera is focusing properly on the subject, and take the photo.
Bumping the ISO up on your digital camera or using fast film allows this. Quite funny images of people or pets can also be made via the use of very wide angle lenses by getting close to the subject creating extreme distortion.
When you apply this photography technique, if you're using a film camera, use fast film. Whether you use a single lens reflex (SLR) or point-and-shoot, load your camera with a film that is ISO 400 or faster. You'll be thrilled with the results.
You may want to go the other way with film. To increase an image's impact, a very fast film will give you maximum grain. (You will probably want to combine the grainy film with an altered development and printing method.).
Lens Choice ...
I was hoping the EOS-3's auto-focus, and fast film loading/advancing would be very helpful. However, since my discovery of the digital camera, I have a really hard time justifying any further investment in film photography.
Long exposures on digital cameras can produce visible noise, which looks a bit like the grain you see in a fast film image. This noise or grain is usually most noticeable in plain areas of the picture.
Fast films, used for shooting in poor light or for shooting fast motion, produce a grainier image. Each grain of silver halide develops in an all-or-nothing way into dark silver or nothing.
Only with a very fast film or ASA setting you have a small change to get that right. Use the flash in these cases, and use the computer afterwards to modify the picture so the light of the flash is not so obvious.
In film photography the ISO was a measure of how sensitive film was to light. It was called film speed. The higher the number, the more sensitive it was (and the film was called "fast film"). E.g.
For most amateur photographers, this info is too technical and not neccessarily too important. Generally speaking, if you are using a moderately fast film speed (ISO 400 and faster) you will get pretty good range out of your flash, ...
The higher the number, the more sensitive or faster the film. Basically, the slower the film (low ISO No.) the sharper and clearer the photograph. Grainy effects can be achieved with fast films (high ISO No.).
One of the reasons that nature pros spend large amounts of money on fast lenses is to give them the ability to work in low light. If you can't afford the fast lenses, you can at least try fast film (maybe Kodachrome 200) to catch the "good light".
The term pronounced by the individual letters: I--S--O, not as if it were the word "ayso" The early term was ASA, which stood for American Standards Organization" Slow film have an ISO rating of 100 and less, while fast films are 400 and higher.
Enlargements made with fast film can have a grainy appearance and color saturation may not be as good as slower films. Films with an ISO of 400 or higher are only needed when light is limited or long lenses are being hand held.
