Photometry & Exposure meters
The visible spectrum range
What is 400-700nm
The 321 rule
What is 3 copies, 2 different media, 1 offsite
This is what CCD and CMOS stand for
What is charged coupled device and complementary metal oxide semiconductor
This is how many bits are in a byte
What is 8 bits in 1 byte
This is how large a TIFF file can be
What is 4 GB
The only type of light source that works with the inverse square law
What is a point souce
This is the easiest to read and why (opacity, density, transmittance)
What is density bc it is linear & additive
This sometimes occurs on a CCD sensor, it can appear as halo or streaking (what is it & why does it happen)
What is blooming, when a photosite overflows with voltage
What is graphics or web illustration
Used in professional DSLR cameras (CMOS or CCD)
What is a CMOS sensor
This is what happens when you meter to a black card, grey card, or white card
What is black= overexposed, grey = correctly exposed and white= underexposed
These are the 4 types of metadata
What is descriptive, administrative, processing and technical
These are the 3 different types of noise
What is photon, transfer process and thermal noise
This is the difference between bitmap and vector
What is bitmap is images stored as pixels/used for photography and vector is images stored as mathematical concepts/not used for photography
This is the equation for bit depth
2^x = number of tones, where x stands for bits
This is what a light source to simulate to be given a color temperature
What is a blackbody radiator
Fill in the blanks: The lower the density, the ____ the opacity & the ____ the transmittance
Lower the opacity, higher the transmittance
This sensor will have more noise (pick). Sensor A has an SNR of 10 and sensor B has an SNR of 12.
What is sensor B. High SNR = less noise
This is what TIFF, JPEG and DNG stand for
What is tagged image file format, joint photographic experts group and digital negative
This is what it means to work non-destructively
What is allowing the image to be adjusted without changing the original data
This is the theoretical illuminance at 18 ft when given 200 lux at 12ft, 16ft, and 18ft (just put numbers in the equation, don't solve)
What is 200/3^2
This is the answer for solving transmittance, opacity, & density with 150 lux incident light and 50 lux transmitted light (just plug in numbers, don't solve)
Transmittance = transmitted/incident = 50/150
Opacity = incident/transmitted = 150/50
Density = (log)opacity = log(150/50)
Fill in the blanks: Low standard deviation would give you a ____ (low/high) SNR
Low standard deviator gives you a high SNR = less noise
This is a description/characteristics of DNG
What is a digital negative, no sidecar, created by adobe, legacy file format, adobe's attempt at standardization
Demosaicing is....
digital image process that reconstructs a full color image from the CFA (color filter array) image → Used to fill in missing color data
