You can still use evalglare, but the tool will be compromised somewhat since it can’t “see” the entire hemisphere. In order to improve the glare prediction, you can supply evalglare with a vertical illuminance reading taken at the same time as you shot the LDR image sequence; this will at least give evalglare some clue about the total energy in the scene, even tho it may be missing the size and location of some potentially large sources of glare.
