Dynamic range

Question 1

what does it mean when your dynamic range goes up?

Answer 1

wide dynamic range
more grays
lowers contrast

Question 2

what does it mean when your dynamic range decreases?

Answer 2

narrow dynamic range
fewer grays and fewer choices
black and white bistable
high contrast

Question 3

what happens when compression goes up?

Answer 3

the number of choices goes up too
increasing your dynamic range

Question 4

increasing compression means _____ contrast

Answer 4

low contrast

Question 5

decreasing compression mean contrast ____

Answer 5

goes up

Question 6

what is dynamic range aka log compression

Answer 6

the amount of decibels that can be processed in that range accurately

Question 7

what improves contrast resolution?

Answer 7

spatial resolution
coded excitation
harmonic imaging
frequency compounding
high compression
edge enhancement
more bits per pixel

Question 8

what is the relationship between contrast, compression and dynamic range

Answer 8

when there’s high compression its high contrast
when dynamic range is high, contrast is low
