What's 24-Bit, 8-Bit and 1-Bit?
Images are described as having so many Bits Per Pixel.
You probably are aware of disk space and file size:
1 byte = 8 bits
1 Kbyte = 1000 bytes
1 Megabyte = 1000 Kbytes (1,000,000 bytes)
1 Gigabyte = 1000 Megabytes (1,000,000,000 bytes)
1 Terabyte = 1000 Gigabytes (1,000,000,000,000 bytes)
Think of a bit as one piece of information. Better described: one bit of information.
An image is made up of many pixels.
An image has a color palette.
If an image is a 24-bit image, then that image uses 24 bits of information to describe each pixel, (24 bits per pixel).
The larger the bits per pixel, the more colors available in the palette.
Example: a 1-bit image has only two colors in the palette: black and white.
A 24 bit image potentially has 16,777,216 colors in its palette.
To learn how to save an image as a 1-bit, 2-bit etc. image, see:
Saving Images Files.
NOTE: PhotoELF can save 32-bit images. However, not all other programs can read 32-bit images yet. This is something new.
If another program cannot open the image, try saving it as a 24-bit image.
