Archived from groups: alt>graphics>photoshop (more info?)

I take my photos in RAW and use a converter tool to convert the RAW into
a 16 bit TIFF file that opens in PhotoShop. From PS I can manipulate
the photo and make it just the way I want it. I'm unable to save it as a
JPG! I went into mode and changed it from 16 bits to 8 bits, still JPG
does not show up as an option when I go to "Save As" or Export.
What am I missing? I'm using PS CS.

Thanks

I guess the mode is not in RGB but in LAB Color or so.
Make sure it is in RGB

Maybe I should have explained more.
Go Image/Mode and change it to RGB Color

The OP clearly says "I went into mode and changed it from 16 bits to 8
bits, still JPG does not show up as an option"...

Thanks for you hep. I got it working now. I thought JPG was a lossy
way to save important images. I thought that tiff retained all the
information if I latter wanted to go back and modify the image. That is
why I use all that disk space.

Confining your work to JPEG pretty much nails your work to the current
technology and makes it impossible to better display the work when high
resolution monitors with greater bit-depth become more common.

This is something certainly to be kept in mind.

TIFF-files - I am working with TIFF-files in windows XP and photo-shop. When there are lot of them, aspecially, in Windows XP it works ferry slow. Is there method to let it work quicker, as quick as JPG- files?
