Details:
A couple mornings ago, if the comet was going to get bright, you couldn't prove it by me. I didn't see it either visually, in 8x56 binoculars, or on the camera screen. To the dawn joggers and dog walkers passing by me on the park loop trail, I was taking photos of nothing and it felt like it. Once back at the computer I eventually located it in a few photos, but even after processing, the comet barely shows, and the tail is marginal (see the bottom inset picture). Labeled and unlabeled versions.
The main photo and the bottom inset photo are the same image. The main photo shows the entire FOV of a short telephoto zoom lens resized down to display on a tablet (hopefully the happy medium between the photo's full size and a smartphone's screen), while the insets are 400x400px crops from their original photos and shown at full size at 1:1 (i.e. the 400x400px area of an inset photo will occupy 400x400px on your screen). Also, the main photo's stars and the comet have been processed to be more prominent after resizing, while the insets are "straight out of the camera (SOOC)" with no processing (except for cropping).
