I was playing with Lightroom 3 beta and discovered that you can now set the background color in a print layout. Excellent! Also, I just happened to generate the following little grid of images that make up a larger panorama. I thought this looked quite nice actually.
I develop these images very flat on purpose to enable better panoramic stitching.
Assembled using hugin and after doing some post treatment just in Lightroom this becomes the following.
This image is 7500x9930 pixels. I have this in a gallery over here, where you can order prints from it. Because of its very high resolution, you can print this image extremely large without loss of quality.
As I promised earlier, when I have time I'll write a little tutorial on how you can do this.
EDIT: playing with the images in LR 3.0 beta, I created the following. This is the top middle image in the collage above but edited individually. This is using the Adobe Standard profile and very modest edits (mostly the blacks and a small amount of added vibrance. I sometimes find such images in my sets that were unintentionally composed quite well.
