Re: 8 bit VS 16 bit in editing
Right. You set this in the workflow options (looks like a URL link below the image). Correct because you want to upload a JPEG and JPEG only supports 8-bit. TIFF or PSD support high bit. I'd stick with TIFF (it does everything that PSD provides). Convert the high bit TIFF to a size you wish to post to the web and in JPEG,… -
Re: 8 bit VS 16 bit in editing
An 8-bit image uses 8-bits to describe each color in an RGB pixel. That gives it 256 possible values for each of R, G and B. That makes 256*256*256 = 16,777,216 possible colors (all possible combinations). A 16-bit image uses 16-bits to describe each color in an RGB pixel. That gives it 65,536 possible values for each of… -

Re: 8 bit VS 16 bit in editing
Good link. I learned alot and will never work with the 8 bit again. Geez...why would I want to lose what I have, but then I don't know what my camera shoots in. Its a Rebel XTI. Any idea? Another question. If I open a photo in Raw and do some editing at 16 bit and then open the photo to CS3...does it stay 16 bit for more… -
Re: 8 bit VS 16 bit in editing
Sure. However, most applications will only send 8-bits of data to the driver, most drivers can't handle more anyway. The new Epson drivers for Leopard (OS X) can http://www.digitaldog.net/files/Epson_Driver_Leopard.pdf and Canon printers have a Photoshop Export module that allows this data to be sent to their drivers. We… -

Re: 8 bit VS 16 bit in editing
Ok...if I edit it in Adobe Raw at 16 bit and then open it to CS3 it stays as a 16 bit for the rest of my editing.....right? Then if I want to save it as a TIFF or work on it later----its a 16 bit. But if I want to post it on my web page I have to change it to an 8 bit. Correct? So what I should do if I have it right is… -
Re: 8 bit VS 16 bit in editing
The following figure might give you some hint of why I like 16 editing. All these are clips of the levels histogram. The top row is a 16 bit image before and after levelling adjustment. Note the smooth curve. I interpret this as a smooth transition of tones from one place on the intensity scale to another. The bottom role…
