What are bitmap images primarily made up of?: Tiny dots called pixels
What is the main difference between bitmap and vector images?: Bitmap images are made of pixels, while vector images are made of lines and shapes drawn using mathematical equations
True or False: The file size of a bitmap image depends on its width, height, and colour depth.: TRUE
What does 'colour depth' in an image refer to?: The number of bits used to represent the colour of each pixel
How many colours can be represented in a 1-bit image?: 2 colours
What is the resolution of an image?: The total number of pixels within a given area
How would you calculate the file size of a bitmap image in bits?: Width(px) x Height(px) x Colour Depth(bit)
Why is metadata important in images?: It provides additional data that helps describe the image
What impact does increasing the colour depth have on an image's file size?: It increases the file size
It increases the number of colours which can be used in the image
True or False: The higher the resolution of an image, the higher its file size.: TRUE
What unit is commonly used to measure image resolution?: Pixels per inch (ppi)
How does colour depth affect the quality of an image?: Higher colour depth allows for more colours and can improve image quality
True or False: Digital photos are an exact representation of the real world.: FALSE
How many colours can a 2-bit image represent?: 4 colours
What is the significance of a bitmap image's width and height in pixels?: They determine the dimensions and detail level of the image
In what way is resolution related to print quality?: Higher resolution usually means better print quality
What would be the file size in bits of a 10px by 10px image with a colour depth of 1 bit?: 100 bits
What would be the file size in bits of a 20px by 15px image with a colour depth of 2 bits?: 600 bits
What would be the file size in bits of an 8px by 8px image with a colour depth of 8 bits?: 512 bits
What type of information does metadata in an image file typically include?: Date and time the image was taken
Camera settings
Location (GPS coordinates)
