Raw vs Tif

Because of the different ways that each 'type' records the data in the 'uncompressed' files. Save as JPG with minimum compression and it will be much smaller, but still larger than the standard compression JPG files.

If you have processed the photo and there are several layers, all that information is stored with image, as are any saved selections and/or masks. That way, if you bring it back later, you could actually add or delete layer information. It gets even larger if you save your layers as "Smart Objects."

A raw file uses a form of proprietary loss-less compression to save space on the memory card in the camera.
When you move the image to the computer and save it as TIF, each pixel gets saved into a universal format that requires 23 bits (2.875 bytes) per pixel.
There are several levels of JPG compression which lose some information from the image that cannot be recovered. Depending on how you present the image, from a computer screen to a print, you might not notice the loss.

I have never heard of a TIF. Can someone tell me how you save a RAW file to TIF? Thanks.

Normally you open a RAW file in some Photo Editing software that is capable of handling RAW files (Photoshop CS6, Photoshop Elements 10, 11 and 12, LR5). Once you have made all your post processing edits, you do a File>Save As>TIF. You would probably want to rename the file before hitting OK

Maybe not. If the new tif file is named [same file name].TIF you will know where it came from.

It's the same way you'd save a raw image to a jpg or any other format. It does vary from program to program so you'd need to tell us which raw editor you use. By the way, raw is not an acronym for anything. It simply is raw as in a raw vegetable is raw and image has raw data.
