how can i do this?
Thanks.
Assuming that you mean a jpeg with 8 bits per channel for a total of 24 bits, and after you have caused PS to read the file, you convert it to an 8 bit per channel Tiff by saving the image as a Tiff.
You convert the 8 bit per channel image in your computer to more than 8 bits by using the 16 bits/channel under the mode tab. PS provides no means to convert to 10 or 12 bits per channel.
It is really pointless to convert an 8 bit per channel image to more than that because the extra bits provide no more information. The extra bits are either not set or full of random garbage.
