Questions about raw, tiff, jpeg, and DNG
Mar 27, 2013

I know raw is just the data.

Here's my question. Specifically, I'm shooting raw with Olympus cameras XZ1, XZ2, and E-LP5.

If I translate the raw into tiff or JPEG with the Olympus Viewer, I have the option to work on it (change contrast, color balance, etc.) before the translation to tiff or JPEG is complete.

Here's my question: Am I losing raw data (information) if I make no changes during translation; will there be less flexibility once the file comes out of Olympus Viewer as a tiff or JPEG? To work on a tiff or JPEG, I currently use Elements 6.

I also know that JPEG changes do entail loss of raw information each time the file is saved; is there any of this in tiff?

Is DNG superior to tiff for keeping possibilities for development?

I'd also appreciate knowing if what I think I know is right.
