- In photographic quality assurance, logarithms are used for the following: Determining density *Plotting characteristic curves . Determining contrast. Determining log H *Reading the densitometer scale. A common logarithm (log l0) is an exponent to a base number of 10. The base 10 is used because our numerical system is based on units of 10.

- Logarithms are used for many common purposes (described as powers of 2 or 10 or e, etc): Photographic exposure increments: 2 EV = N²/t so EV = log₂(N²/t) Ph scale of acidity in chemistry: Ph = -log 10 (hydrogen ion concentration). Distilled water is Ph 7. Interest rate and biology (growth calculations, log e).

- With logarithms a ".5" means halfway in terms of multiplication, i.e the square root ( 9 .5 means the square root of 9 -- 3 is halfway in terms of multiplication because it's 1 to 3 and 3 to 9). Taking log (500,000) we get 5.7, add 1 for the extra digit, and we can say "500,000 is …

- A logarithm is the answer to the question what power x do I need to apply to the base b in order to obtain the number y: log_b(y) = x is another way of specifying the relationship: b^x = y. Let’s plug in some numbers to make this more clear. We will do base-10, so b=10. log_10(100) = 2 The base-10 logarithm of 100 is 2 because: 10^2 = 100
