Print HDR Images from Photoshop CC

You can’t actually print an image in 32-bit color at all from Photoshop (the Print and Print One Copy commands are disabled). Well, you can’t really print the entire tonal range of a 32-bit image — no printer (or paper) can handle the range.

What you can do is print a 16-bit (or 8-bit) image that has outstanding highlights, outstanding shadows, and outstanding midtones.

After saving the 32-bit original, use Photoshop’s Image→Mode→16-Bits/Channel command to convert to 16-bit color (using Local Adaptation). After changing the color depth, choose Image→ Image Size to set your desired print size.

You can either deselect the Resample check box and enter your desired print dimensions, letting Photoshop calculate the new resolution, or you can use the Resample option and input both the print dimensions and resolution.

The resampling algorithm should be set to Bicubic Automatic or Preserve Details (when enlarging the image), not Nearest Neighbor or Bilinear, neither of which is appropriate for most photos. (Those are your only four options when resampling a 32-bit image.)

When the image is ready, open Photoshop’s File→Print window. Choose the printer and click the Print Settings button to set up the printer. Choose the specific paper on which you will be printing and disable the printer’s color management. Choose the printer’s resolution and — if your printer has the capability — select 16-Bit Output.

To the right in Photoshop’s Print dialog box (as shown), make sure that Photoshop is managing colors and that you have selected the printer’s own profile for the specific paper on which you are printing. Generally, you should use the Relative Colorimetric rendering intent and Black Point Compensation. (Note that if your print is way too dark, Black Point Compensation should be disabled.)

You need to make all of the printer-specific choices by clicking the Print Settings button before clicking the Print button. If you want to save this 16-bit version of the image, use Save As to create a new file. Using the Save command would overwrite the 32-bit original HDR image.
