When I finish work in the RAW converter, should I convert to JPEG or TIFF when I need to do resizing in another program?

It's generally best to stay in TIFF format until you're completely done with it, because of the data that's lost every time you save a JPEG file.
Here's an article that helps explain it (external link).

Do you get a similar result if you save to a photoshop doc file (PSD) after converting to raw - no reduction in quality each time you save?

This is what I normally do. Then I save the final image as a jpg and normally keep the PSD file in case I want to make further changes after seeing a print.

Yes, that is correct. That's what I do, too.

I save as a tiff & write over the "conversion tiff", to avoid having another large file on my drive.

Generally, for the simple shots, RSE saves the conversion info so I can delete the big tiff file & save a lot of hard drive space in the long run.
Only for complex shots with many layers will I save the final tiff after I'm done with it.

I just found out that my lowly PSE3 allows me to save my images as lossless Jpeg 2000. The images saved are not as huge as .tiff but seems to retain the full quality as a full blown version. Does anyone have experience with Jpeg 2000?

I don't know what you mean, but if you mean, for instance, can you see j2k images in, let's say, Windows Viewer, the answer is no. I can see the images using PSE3.

Web browser, such as IE, Netscape, or Firefox. Also, what printing services accept this format?

As for which printing services, I haven't a clue as I'm, like you, just learning about this new J2k myself. Anyone knows?

I've just posted some more information about JPEG 2000, browser plugins and so on in this thread.

I have various jobs to do, including rebuilding my FreeBSD box under FreeBSD 6.0 (I'm choosing to go for a complete rebuild to upgrade from 5.4 to 6.0 rather than trying to upgrade 'in place'). When I've done that, I'll install Apache on it, and experiment with various things including JPEG 2000.

David
