I have been using photoshop elements for some time but i am a newbee to photoshop cs. Can anyone tell me how to convert my old 8 bit files into 16 bit files. Ive searched the help menu but have found nothing. Thanks, Kevin

Well 8 bit files will have only 8 bits of information even if you convert them to 16 bit, they will be 8 bit in a 16 bit space.

Image/Mode/16 bits

But what benefit are you expecting by converting 8-bit to 16? Are you re-editing?

Obiously these images won't have more color once converted but will give more editing possibilities.

From the tutorials that ive been reading, 16 bit files when printed are far superior to 8 bit. I just want to edit some of my files for print.

Thanks kirbic, I didnt know it was that easy.

That's because 16 bit files have more information than 8 bit files, but if you are starting with an 8 bit file and converting it to a 16 bit file you are not getting any more information...

There are some limited cases where going from 8 bits to 16 makes sense, one of these is if you are going to resize smaller. When going smaller the new pixels are made from a number of pixels and so there is a bit of averaging that goes on, this can add a bit or two if color depth depending on how much you resize.

So will new files be saved as 16 bit automatically in photoshop cs?

When converting from RAW, at the bottom left there is a pull-down box to choose the bit depth of the converted file. Shots taken originally as JPEG are always 8 bits/channel.
