I thought I knew p/shop. Apparently not so.

Am I not able to add layers (adjustment layers) when working with a TIFF file? I have converted some RAW files to TIFF, then when I go to open them, ALL of the options under the Layers menu tab are darkened... I can't do anything.

Is this normal? Do I have to save it as JPEG before this?

Sounds like your image may not be RGB or CMYK. Have you checked this? It's not normal since you can save a TIFF with layers in Photoshop 7.

This is a question I'd like answered, too.

With TIFF files, I need to convert them into 8-bit from 16-bit before I can photoshop them. Is there no way to retain the 16-bit depth while working in photoshop?

I'm using 5.5 by the way.

on top of the image window it reads RGB.

It wasn't much of an issue, but now I can't save the TIFFs as a JPG when I'm done..

Can you e-mail one of the files to me? I'll have a look at it:
cyberpix@homeland.plus.com

You can reduce the file size for the test or zip it if you like.

I just realised that you may have the image at 16bit. This will prevent you adding layers. Try converting it to 8bit.

When you are WORKING WITH files, save them in "native" Photoshop format, which should support all of the features. When you are DONE, save a copy as a TIFF, flattening the layers.

TIFF is a format designed to be placed into other documents and printed, not particularly for editing.

This was my original question. Why can't photoshop work with 16bit?
