How do I ensure my images from the camera are in 16 bit depth and not 8.....or can this only be done in ACR.
Thanks
Dave
 
??

If you take JPEGs you will only get 8 bit depth. RAW will take higher bit depths and you then (typically) develop these into 8 bit JPEGs for later display. It's the develop process that allows you to control the transfer from higher bit depths to lower, rather than letting the camera decide for you.
 
Andy - sorry, I'm still a little confused. Its a friend of mine who has asked me this question and I dont know the full answer to it.
He says with his Nikon D90 he was getting 16 bit out of the camera but now with the
D7000 he is only getting 8 bit.
I have mentioned about the 12 and 14 bit depth in the Shooting Menu under the NEF (RAW)Recording tab.
So if he chose 14 bit lossless in camera would he still need to be changed in ACR to 16 bit??
Appreciate any help
Thanks
Dave
 
Yes :) ACR will convert to 8bit on import if you don't select 16 bit.
 
The camera can usually output either 8 or 16 bit (normally 12 or 14 bit actually) if you put a 8 bit image into camera raw and output it as 16 bit what your doing is putting 8 bits in a 16 bit wrapper.
 
Thanks Wayne, so how do you output a 16 bit from the camera?? is it by inputting lossless compression then in RAW (Recording) earmarking the 14 bit depth, or by some other means

RAW is normally either 12 or 14 bit. it's the RAW conversion software that does the conversion to 16 bit. not the camera. So what is happening is the camera is outputting the RAW file ( in whatever bit depth it works in ) and that file is then processed by the software ( in this case ACR) to give a Standard output in either 8 bit or 16 bit. So the RAW conversion software needs to be set to 16 bit.

Hope this helps

Thanks for your help

What software are you using ? I can help with ACR and Lightroom, but as I'm a Canon user not much help with NX or similar

Hi Dave

In ACR at the bottom you can see some text (circled) Click that then when the window opens click the dropdown and change it to 16 bit HTHs also it will remain that way as a default setting so no need to keep changing it everytime
