|Alpa STC, IQ 180, 32 HR, ~f/11, ~7s, ISO 100|
So where did I goof up? First, my back was set to ISO 100 and not ISO 35. If you try doing longer exposures (like multiple seconds) with the IQ 180 at ISO 100, it starts degrading image quality. Its not huge, but its noticeable. This goof was purely inattention on my part, I had set the back to ISO 100 for some other faster shutter speed work I was doing earlier in the day and simply forgot to check to put it back to 35.
Second, I had my tripod set up on a wooden bridge and with moving walking over it and a 7 second exposure, you inevitably get blur which is exactly what I got when I zoomed in to 100% and closely examined the pixels. Normally I would time my exposures to avoid people walking and do multiple exposures as insurance. In this case, I wanted to stick to 1 so I had to live with this one.
In the end, this gave me a somewhat mushy file to work with. After cropped to my panoramic aspect ratio and then resizing to get back to an image with actual detail at the pixel level, I was left with a 10mp image. If I hadn't goofed on the ISO and the shake, I would have had a super crisp 40mp panorama. Oh well, at least I got a neat monochrome with Silver Efex Pro.
