•  Resolution: The size of a digital image on your screen is measured in pixels.  Resolution 

is simply the measurement of an image’s width and height.  For example, an image that 

has a resolution of 100 x 100 means that it is 100 pixels high by 100 pixels wide.  A 100 

x 100 image may still look different on different monitors.  This is because your monitor 

has a resolution as well.  Some people have their monitor resolution set at 640 x 480; 

others have it as high as 1600 x 1200!  In general, monitors with a higher resolution will 
make pictures look much smaller than on a monitor with a lower resolution.  Why?  A 

100 x 100 image will take up approximately 1/6 of the screen width of a monitor with a 

resolution of 640 x 480.  By comparison, the image will only take up 1/16 of the screen 

width of a monitor with a resolution of 1600 x1200.  It’s the same image, but because of 

the different screen resolutions of the two monitors, they appear different in size. 

•  DPI: This can be a bit confusing, but in principle it’s very simple.  When printing within 

PhotoStudio, the size of the printed image is directly dependent on two things: 
resolution and DPI (dots per inch).  By setting the DPI for a photo, you determine how 

many pixels will be contained in each inch that is printed.  For example, if you have a 

photo that is 1000 x 1000 and print at a DPI of 100, you’ll get a 10” x 10” image.  

Because the image is 1000 pixels high and you’re printing 100 pixels in an inch, you’ll 

have a print that is 10” high.  Here’s the confusing part.  The DPI that you see in 

PhotoStudio that is used to set your print size is 

not the same as the DPI used to 

describe the capabilities of your printer.  For example, some printers can print at a DPI of 

2000.  This means that for each inch that the printer prints, it will shoot out 2000 

individual dots of ink.  Within the software, DPI refers to pixels printed per inch; with 

respect to your printer, it refers to the number of individual ink dots the cartridge puts on 

the paper within a single inch.  A printer my use several dots of ink to make one single 

pixel of the photo. 

•  Image Acquisition Device: An “image acquisition device” is any hardware device that 

you can connect to your computer so you can download, or “acquire” images.  These 

include digital cameras, scanners, and webcams.  It’s basically a fancy term that has 

been adopted to describe these things. 

•  Driver: Drivers are actually programs or files that are placed on your computer 

whenever you install a CD that comes with a piece of hardware.  A driver basically tells 

the computer what device you have, and is responsible for transferring data back and 

forth from the device to your computer.  Every piece of hardware you have on your 
computer has a driver.  Your printer, your video card, your modem, your sound card…  

all of these devices have a driver installed on your computer that tell it exactly what the 

device is, what it does, and how it does it.  When you installed your flashy new digital 

camera software, the drivers for the camera were installed as well.  You can acquire 

photos from your devices 

through PhotoStudio, but the program is basically a spectator 

during the actual download or acquire process.  Whenever you acquire photos, 

PhotoStudio basically sits and waits while the driver for your device goes to work.  If 

you’re having problems downloading/acquiring images, contact the manufacturer of your 

camera (or other hardware device) to see if they have an update.  Most companies have 

their drivers available for free download on their Web site, and update them whenever 

issues arise.
