Description

A beautiful July 4th concert featuring the National Repertory Orchestra and the Lake Dillon Theatre performers. See how many American flags you can spot!

Created using a Canon T1i and Gigapan Epic 100. APG output to HDR to Photomatix for tone mapping to accentuate the holiday colors and scenic background, then blended HDR and standard exposure shots by hand in Photoshop to eliminate motion bluring of the people in the scene.

    I want to reiterate that you stitched a great panorama and that doing HDR or focus stacking adds another level of complexity, effort, and time. Especially with large panoramas. Masking is still an excellent tool that can yield the best results for compositing parts of an image. You can use a mask with a gradient to blend skys if there are not well defined edges. Also, learning how to use setting of the refine command of a selection is important. I have looked at the projection coordinates from an APG file and thought of using that file in another directory with file renamed to match the old files. I ended up rendering different versions of the panorama and changing the levels. Then I mask the different versions. It works well because it is from the same stitch without having to try and feed other files to the stitcher. You can also do this with HDR images stitched into an HDR panorama. Though there will be a linear camera curve without a gamma applied which will seem dark. You can render non HDR files and mask them together. Then you are able to change the levels without image degradation. I usually use the openEXR format and sometimes the .HDR format depending on which tools I use.

    To your point about combining the exposure brackets first- yes I have found that as well. However, in this case what I wanted to do was layer mask a single exposure panorama over portions of the HDR to cover up motion blur. What I could not get was APG to create an exact match of the two panos with the following workflow: 1) Create an HDR pano from HDR exposures 2) Create a standard exposure pano from just the single exposures This wasn't because of HDR image alignment when making the HDR pics, and I made sure that the focal lengths, etc were the same when using the HDR exposures... it just turned out sightly different each time so I couldn't line the images up consistently across the two panos. So thus the use of APG to generate the HDR. I'm open to suggestions on other workflows or techniques- I was hoping somehow I could save the exact projection information and reuse it with the other 'matching' images but couldn't get it to work. Agree on the saturation - wanted to go exaggerated versus realistic for the 4th colors, but probably went overboard.

    Great job. Usually it is much easier to combine the exposure brackets first before stitching the images. Also, you might want to reduce the saturation as the colors are much too saturated. Though, great job and thanks for explaining your workflow.
