Join Deke McClelland for an in-depth discussion in this video Downsampling advice, part of Photoshop CS6 One-on-One: Fundamentals.
The previous movie was a bit academic, which is why I want to show you how these…interpolation settings affect an actual continuous tone photograph and offer you…some advice for how to use them.…So what I did was take this high-res panorama and then once again choose the…Image Size command, make sure Resample Image was turned on, set the Resolution…value to 100 Pixels/Inch, just as I did when downsampling this image for email,…and then I tried out each and everyone of the manual interpolation settings.…And let me show you what that looks like.…
I'll switch to this file called Interpolated panos.psd.…Notice that we're seeing the image at the 100% view size.…I'm going to zoom in quite a bit here because we'll need to see these pixels in detail.…Now once again this file has layer comps inside of it.…This first slide shows the result of downsampling the image using the Nearest…Neighbor setting, which just drops pixels, and as a result we end up getting…this pretty choppy detail.…One might argue that the detail is very crisp and we don't have any halos around…

Q: When I double click the welcome.psd file included with the exercise files, I get the following error message:
"Some text layers contain fonts that are missing. These layers will need to have the missing fonts replaced before they can be used for vector based output."
Unlike the TIF and JPEG files which display and open correctly, all the icons for PSD files are blank but other than the welcome.psd file, they seem to open correctly without the error message. Is this a problem that I should address (perhaps re-download the files or find the missing fonts)?
A: The TIFF and JPEG files are flat, so they don't contain fonts and the operating system can interpret them (and generate thumbnails) without help from Photoshop. The PSD files have two issues:
First, they may contain editable text complete with font info. The files are designed with fonts that ship with Photoshop, so you don't get error messages, but Adobe sells some versions of Photoshop without fonts. This may be your issue.
Second, the PSD files contain no flat previews. This makes for smaller files, but it means the operating system, Mac or Windows, cannot generate previews. That won't effect your experience in Photoshop, but it does mean you can't see the file until you open it.
