File Formats are limited?

I imported a scanned tif. Silhoetted the area I wanted to mask, created a clipping path and tried to save as an eps but my saving options were limited to Photoshop, LDF, PS PDF, PS Raw and tiff. I didn't get the 20 or so other saving options which includes EPS.

I'm on Mac OS10.5.5. Running CS3 10.0.1.

I can only get the big file format box by creating a new file and placing the picture in it and then doing a "save as" and I get the other formats.

Is this correct?

sounds like you have a 16 bit file

Thanks Buko!

You're right. I asked the source and he accidentally scanned at RGB 48 bit.

Luckily I found a work around.
