Resolution X Pixel depth = approximate ".RAW" file size

Pixel depth is usually 32, 16 or 8 bits, 4,2 or 1 bytes. So, 16 million colours = 4 bytes per pixel.

980 X 1020 X 4 = about 4MB in RAW format

TIP: JPG's are smaller because they are compressed..

Different compressions give different sizes of same picture. But to save the image with full color information (without quality loss) you can save it either in hi quality Jpeg or 24bit PNG.
Both these are offered by Adobe Photoshop.

You will get the following size in both these formats.

PNG – 232 KB
JPEG at 100% quality – 270 KB

However it may depend on the information presented in the image.

You can save a JPEG or PNG in MS Paint also. For this you can go to Run in windows' start menu and type “mspaint”

In photoshop you can use “Save for web command”.

Depends on the dpi of the image, and what format and level of compression you are using.

Put it in compressed (zipped) folder and burn it to cd.
