Help -10d RAW - Converting to PSD

Thanks John - I'm not really familiar with TIFF files, and had thought that you couldn't produce layers using the TIFF format.

Just a question - are there compression issues with TIFF files the way there are with JPG files? OR - I guess I should ask - does TIFF compress RAW files?

I know in Photoshop 7.0 you get a dialog box when saving a TIFF files that allow you to choose different levels of compression. The first option in that menu is no compression.

Can't say I know the answer to your second question about whether there is a loss of quality when going from RAW to Tiff. I would think very little if any.

TIFF files do support layers and they're lossless. YOu can save with no compression at all or you can save compressed TIFFs. Even compressed TIFFs are lossless - at least they're supposed to be. The other nice thing about TIFF files is that all software can handle them. PSDs are an Adobe-specific file-type. So using the TIFF format is a better long term solution.
