Join Julieanne Kost for an in-depth discussion in this video Choosing color modes and bit depth, part of Photoshop CC 2018 Essential Training: The Basics.
- [Instructor] We're going to take the next few minutes…to look at the most popular color modes in Photoshop…and the role that bit depth plays in their ability…to store information.…Bit depth specifies how much information is available…for each pixel in an image.…The more bits of information per pixel, the more…values are possible, and the more accurate…tonal representation can be achieved.…For example, an image with a bit depth of one can…only display two possible values.…Black or white.…As a result, one bit images are not very common…when you're working with photographs in Photoshop.…
An image with a bit depth of eight, can contain…256 possible tonal or color values.…Making eight bit images much more useful…than one bit images.…Photoshop stores this color information in a channel.…And there are three common types of files that you'll…work with that are all considered to be eight bit,…but have very important differences based on the…values that they contain, and the number of channels.…The first is a greyscale mode image.…
