iPhoto Question

[frownsarefun]

Let`s say I have two photographs stored on a hard drive. One is a RAW file and one is a JPEG. With everything that I know, the following things are true:

- The RAW file is going to get copied into the iPhoto library and turned into a JPEG.

- The JPEG file is also going to get copied into the iPhoto library and remain a JPEG.

- Each time I open these JPEGs and make changes, they lose a bit of quality, however small or noticeable.

- iPhoto 11` lets you save edits as 16-bit TIFFs.


So after I import these two photos - should I immediately save them as TIFFs (untouched and unedited). And then go ahead and re-import them as TIFFs and make all the changes I wish.

Or should I import them as iPhoto does, make the changes and then save them as TIFFs.

I want to turn the JPEG into TIFF and the RAW files also to TIFF. But since I might not finish editing the images in one sitting, I don`t want to risk losing quality.
