Thanks! I live near Denver. Those pictures are from Longs Peak and Chasm Lake in Rocky Mountain National Park.
I did these things in Lightroom 2.6 completely. What you do is select your set of images and go to the Print panel. There you set up a print layout with your images and with the requisite spacing between images. Then output/print it to a jpeg. There are many tutorials on the web on how to do this. Often they are called things like “creating a triptych in Lightroom” (see here 
. It takes a little playing to get the layout right. Your idea sounds like it would work perfect with this method. Match total exposures is a Lightroom thing. You can find it if you have multiple images selected in the Develop pane in the Settings menu. Also make sure you sync the white balance across the images. Match total exposures takes the EXIF data your camera stores on the exposure of your images and equalizes them using exposure compensation. If the exposures are not off more than 2/3 of a stop or so this should work just fine and get you really close. As said, the best thing to do is to take the individual images in manual exposure mode and then you don’t have to do anything. They come out perfectly matching apart from maybe a little lens vignetting, which is usually completely gone at f5.6 and above on most lenses.
