The numbers refer to film speed or ISO; witch is another way of saying sensitivity. Each of the standard ISOs (listed bellow) is twice as sensitive as the one before it. The higher the number is the more sensitive the film. While a higher sensitivity film will allow you to shoot in lower light conditions it increases the appearance of grain. Not sensitive
about £200-£400 is my guess
Three to four gallons, depending on condition of the surface and how heavily the paint is applied.
30 dollars on small events big ones 150 to 200
300 to 400 in the spartan 1 project, 250 to 300 in the spartan 2 project, and less then 200 in the spartan 3 project.
ASA acronym for American Standards Association - hence ASA400 on films is the standard film speed of 400. ISO is International Standards Organization. the two values are identical, for once there is no separate ( Metric) or different European film standard. The Germans do use the DIN ( German Industrial Norms) standards this is such that that- DIN 27 is equivalent to ASA 400. ASA and DIN are the only common film standards used today. There you have it. Get yourself a Photometer and the meanings of the various scales will be self-evident. Besides you can learn much about differing exposure values- for nearly every potential shot there are more than one possible (answers) so there are considerable variables around. Experiment!
200 percent of 400 = 800200% of 400= 200% * 400= 200%/100% * 400= 800/1 or 800
hay
200 = 400
400 + 200 = 600
200 + 400 = 600
200*200=400 200+200=400
((400 - 200) / 400) x 200 = 100 Therefore, the percentage increase is 100 percent.
It is the same as 400 divided by 2 which equals 200
400 * 200 = 400 * 100 * 2 = (400 * 100) * 2 = 40000 * 2 = 80000
Twice because 400/200 = 2
400
You would be exposing it as though it were ISO 800 and developing accordingly.
