tiff is a very beefed up way of storing digital media images. it also can take up a lot of room.
RAW is very argued format. For the most part, in digital cameras, the light is recieved, processed and then coded into varies media formats such as jpeg, bmp, tiff, etc. RAW is the unprocessed, uncompressed media that will or will not contain the original white balance and various other useful tidbits.
Now, if you take photo's for printing and sharing with family and friends, you might just want to stick with tiff or jpeg. However, if you take photos with the intention of image processing and editing with photoshop and whatnot, i would suggest using raw. *Be warned* RAW is an argued format that is not universally standard and supported like the other formats mentioned. So you might want to take some test shots and try loading them into a photoediting program first before you try recording babies first steps. :btu:
