This test is made up of 2401 images. The capture duration was about 2.5 hours, with a 500ms settle between frames. Luckily this worked out from centre, but later I realized that (a) spirals can only do square grids, and (b) that the 0 tilt is not the centre of the tilt range. The auto white-balance and exposure does not work very well in this situation. I could deal with the contrast effects to some degree, but the auto white-balance is problematic. Notice the edge effects around the cabinets. The next step is to use a light meter to do manual exposure and turn off auto white-balance.
One of the most interesting results is the out of focus images that happen in areas with little contrast. I’ve chosen a couple of details from the above images:
