Some bash scripts used in my focus stacking process

group-focus-stacked-photos.sh

# Grouping pictures into folder by count (6 in this case)
counter=0; group_number=1; for img in *.jpg; do [[ -e "$img" ]] || continue; if (( counter % 6 == 0 )); then mkdir -p "group_$group_number"; ((group_number++)); fi; mv "$img" "group_$((group_number-1))"; ((counter++)); done

process-focus-stack-groups.sh

#!/bin/bash

# Path to Hugin tools
HUGIN_TOOLS="/Applications/Hugin/tools_mac"

# Iterate over subfolders
for folder in */; do
  # Handle spaces in folder names
  folder="${folder%/}"
  
  # Create a directory for aligned images
  aligned_folder="$folder/aligned"
  mkdir -p "$aligned_folder"

  # Align images using align_image_stack (case-insensitive match for jpg and JPG)
  "$HUGIN_TOOLS/align_image_stack" -m -a "$aligned_folder/aligned_" "$folder"/*.jpg

  # Perform focus stacking using Enfuse
  "$HUGIN_TOOLS/enfuse" --saturation-weight=0  --exposure-weight=0  --contrast-weight=0.08 --gray-projector=luminance --contrast-window-size=3 --output="${folder}_stacked.jpg" "$aligned_folder/"*.tif

  # Clean up temporary TIFF files (optional)
  rm "$aligned_folder"/*.tif
done

testing-settings.sh

# An example script I've used to test various settings of enfuse to see what works best
# It iterates over some values (For one parameter) and geneates masks (converts them to png) so that you can take a look
for contrast_weight in $(seq 0.1 0.1 0.9); do /Applications/Hugin/tools_mac/enfuse --saturation-weight=0 --exposure-weight=0 --contrast-weight="$contrast_weight" --gray-projector="luminance" --contrast-window-size=3 --save-masks="mask-test-weight-${contrast_weight}.tif" "/Users/sasha/Creative/Photogrammetry/photostacking test/set 1/0A1A8152.JPG" && magick "mask-test-weight-${contrast_weight}.tif" -depth 8 -channel RGB -fx "round(255 * r)" "mask-test-weight-${contrast_weight}.png" && rm "mask-test-weight-${contrast_weight}.tif"; done
