Getting Technical
Understanding the technical jargon used in digital photography can be confusing. Below are some definitions and examples of the terms we are most frequently asked about when working with you on feature and release projects.
Vignettes:
A vignette is a photograph whose edges fade out gradually. In photography, vignetting can be an unintentional result caused by optical limitations in the camera lens. As an effect, it is frequently used for portrait photos, usually in an oval or other shape.

Resolution:
The term DPI and PPI are often used interchangably, causing a lot of confusion, however, DPI refers to the resolution of a printing device while PPI refers the resolution of the image.
|
|
DPI: DPI stands for dots per inch. DPI is a measurement of printer resolution that defines how many dots of ink are placed on the page when the image is printed.
|
PPI: PPI stands for pixels per inch. PPI is a measurement of image resolution that defines the size an image will print. The higher the ppi value, the better quality print you will get--but only up to a point. 300ppi is generally considered the point of diminishing returns when it comes to ink jet printing of digital photos.

CMYK & RGB: |
CMYK – This color space is based on the ink colors used in traditional full-color commercial printing: C yan, M agenta, Y ellow, and blac K. In general, it is best to edit your images in RGB color mode because many software features and commands will not be available in CMYK mode.
RGB –This color space is based on the primary additive colors of R ed, G reen, and B lue. This is the most common color mode used in graphics software.
