This section starts with the TIFF version of the photograph of clouds behind a mountain as it was at the end of the “Edit original option” section earlier in this lesson. This file should be in the students’ Lightroom catalog as DSCF0431-Edit-P.tif. This version of the image is not in the original lesson files; it was generated during this lesson as a derivative of the Lesson 2 DSCF0431.dng file. You’ll find a summary of all the adjustments that were made to this file so far in this section.
Tweaking the RGB file again in Lightroom This section instructs students to make a few final adjustments to the final image, DSCF0431-Edit-P.tif, in Lightroom (adjusting the Lightroom black and white conversion applied earlier in this lesson, and adding a vignette). Counsel students to think of the resulting image in Lightroom as the master file. It contains all the adjustments added in both Lightroom and Photoshop through a series of roundtrip edits. It hasn’t been reduced in size, compressed, or otherwise compromised. This is the file to return to whenever someone needs a copy of the final image for a particular purpose.
Exporting from Lightroom Photoshop users are accustomed to outputting images by saving and often end up saving multiple versions of an image in different formats and sizes for different purposes. There is no save command in Lightroom. Instead, students can use Lightroom’s Export dialog to efficiently generate a copy of an adjusted image at any time with whatever output parameters are needed at the moment. This section walks students through the process of exporting a copy of the “master file” they generated during the Lightroom–Photoshop workflow in this lesson, DSCF0431-Edit-P.tif. They’ll set all the parameters they need to export a copy of the file to post online, including file format, size, color space, filename, sharpening, and more. You can supplement this section by discussing how to set these parameters for other use cases, like printing a large print on matte paper, or printing small cards on glossy paper. If students have access to a printer, you could have students print a copy of the completed lesson file one of two ways:
• Export a copy of the file with the proper export parameters for print. Open the exported file into Photoshop, and print from there.
• Print the image directly from Lightroom’s Print module. For information about the Print module see Adobe Lightroom 5 Classroom in a Book.
