Riverside Sunset at Golden Hour — Bakkhali River, Bangladesh

100 photographs of sunset over the Bakkhali River at low tide, near Cox's Bazar, Bangladesh. All frames were captured in a single evening session on 13 July 2026 (17:59–18:24 local time, UTC+6) during golden hour.

Contents

  • —100 JPG images, 2000×1333 px, filenames riverside-sunset-golden-hour-004.JPG through -108.JPG. Numbers are not fully sequential — 100 of 110 frames captured during the session were selected for this release, so some numbers are skipped.
  • —metadata.jsonl — one record per image with capture time, camera settings, and location fields

Capture methodology

Shot handheld with a Nikon D7200 and 18-140mm f/3.5-5.6 lens at 52mm, ISO 100. Aperture (f/4.8–f/8) and shutter speed varied across the session as the light faded, which is expected for a sunset sequence. The photographer walked roughly 0.5 km along the riverbank during the shoot, so vantage point is not fixed between frames.

Known limitations

  • —In-camera processing is not consistent across the set. Picture Control profile varies (Standard, Landscape, and Flat all appear), along with mixed Auto/Manual exposure mode and Active D-Lighting Auto/Off. This produces some visible tone and contrast differences between frames beyond what the changing light alone would cause. Each image's picture_control, white_balance, and active_d_lighting values are included in metadata.jsonl so affected frames can be identified or filtered.
  • —File numbering has gaps (see Contents above) — this reflects frame selection, not missing data.
  • —Single location, single evening session; vantage point varies but stays within ~0.5 km of the same stretch of riverbank.
  • —No per-image GPS coordinates; location is recorded at site level only.
