![]() You may see slight banding at 100% preview that isn't in the data, that will not print this way. So it is kind of nice to have a high bit video path but not something everyone needs. But if you see banding on-screen using high bit data, it's banding from the video path, not the data itself. (Although it’s still best to keep the 16 bit TIFF or PSD in your archive, in case you decide to do more editing later. Only once the editing work is done is it a good idea to convert it to an 8-bit image for output. ![]() (You need to decide the value in each plane by 256) Thats not true at. This has no bearing on the data you are editing. Even though Photoshop’s 16-bit/channel images can only hold 12.5 of the theoretical maximum value. The only difference between 16 bit rgb and 8 bit rgb is the range, 16 bit has values form 0 to 65536 while 8 bit has values from 0 to 256, hence you should just be able to devide a 16 bit rgb value by 256 using integer division (for simplicity) and that will be it converted. With a full high bit video path, meaning the panel, video card, OS and application (so Photoshop fits that bill), one can get a full high bit video and one can see the difference using the correct kinds of documents like: My display is 12 bit (NEC SpectraView) and a few other manufacturers have this as well. ![]() Also, choose to work in 16 bits per channel for greater color accuracy. I can't see nor measure any difference in output sending 8-bits per color or the same document in 16-bits per color. Analysis: todays printers don't need more than 8-bits (good) per color. If youre working with a traditional image in Photoshop, converting to Smart. To convert from 8 or 16 Bits/Channel to 32 Bits/Channel, choose Image > Mode > 32 Bits/Channel. the image is not flattened) when you convert the image to 16 bits, Photoshop recomputes the result by reapplying the layers in 16 bit mode and thus giving you a better gradient. So my Epson 3880 (Mac only) has a high bit path (ȁ6-bit check box) and option in the driver. It may be that if you still have the layers (i.e.
