i have several photography questions…?
1. The larger the silver halide crystals in the films emulsion (A) the higher the film speed rating (B) the slower the film speed rating (C) the more likely the film will be overexposed
2. Faster films are (A) more sensitive to light (B) not as sharp as slower films (C) both A and B
3. In tri-pack film construction each one of the three emulsion layers is (A) sensitive to a different color of light (B) sensitive to different ISO setting (C) contains a different size of silver halide crystals
4. Color films (A) are more sensitive to exposure errors than black and white film (B) do not have as much latitude as black and white films (C) both A and B
5. After they are mixed by chemicals for film development should (A) used immediately (B) kept in air-tight containers (C) stored in a refrigerator
6. developer should be stored in (A) clear glass bottles (B) containers that block light (C) uncovered metal plates
1. A is the most correct, although C is also true since faster films tend to have more contrast, making exposure more difficult.
2. A-faster films are more sensitive to light. They’re also sharper, as the larger grain allows details to be more defined. Slower films tend to be mushy and not as sharp.
3. A-each layer is sensitive to different wavelengths of light
4. C-both A and B are correct
5. A is always preferable, but if developer must be stored, it should always be stored in full, air tight containers.
6. B-developer should be stored in amber bottles at the very least, and preferably in completely opaque bottles.
EDIT:
Sharpness and resolution are not the same thing. Yes, slower films have a greater ability to record fine detail. The grain in faster films, though, tends to make what details are recorded stand out more, so they actually appear much sharper.
By contrast, slower films tend to be sort of mushy. Yes, the detail is there, but it doesn’t pop out at you as much as it does with grainier films.
