Join Taz Tally for an in-depth discussion in this video Capturing high dynamic range (HDR) scans , part of Scanning Techniques for Photography Art and Design.
Here I'd like to show you how to create an HDR or High Dynamic Range scan.…This is probably the simplest of all scans, because the intention of creating a…High Dynamic Range scan is to just capture as much data as you can and offload…the editing of that data to another application, be it Photoshop or Lightroom or…the HDR program that LaserSoft makes.…Basically all that you need to do, in fact, the only thing that's active in…this dialog box, if you go to HDR Scan, is to set up your Frame here, set up…any Scaling that you might want to do, and here we'll just take this image at…100%, 8x9 frame, 240 pixels per inch, for a resolution for printing on a high…quality inkjet printer.…
And then normally we would set our Scan Type at 48-24 bit or 48 bit color.…What we'd do here is 48 bit HDR, or High Dynamic Range color.…And notice what happens to all the tools when we select that.…All the tools up here just go away, you have no way of actually editing your image.…All you can edit is down here with the Scale and the Output and the Resolution,…
