Note: Storage Paths
Short-Term Storage:
Downloaded images are stored temporarily at:
/home/psa_images/temp_data/field_data/
Long-Term Storage:
Images are transferred to long-term storage at:
/mnt/research-projects/r/raatwell/longterm_images3/field-batches
1. Connect to Sunny
SSH into Sunny and navigate to the following directory:
/home/psa_images/field_tools
2. Download New Image Batch
To download a new batch from the Azure field-batches blob container, run the following command:
python download_raw_batch.py [BATCH_NAME]
Example:
python download_raw_batch.py AL_2023-10-06
The batch will be saved in:
/home/psa_images/temp_data/field_data/
3. Open RawTherapee
Run RawTherapee using the command:
./RawTherapee_5.10.AppImage
In the file browser, navigate to the newly downloaded batch and browse the images.
4. Apply Processing Profile
Select Representative Color Checker Image:
Click on the color checker image to expand it.
Load Profile:
Apply a pre-made profile by right-clicking the selected image:
Right-click →
Apply
→My Profile
Alternatively, if right-click isn’t available, use the Folder icon in the Processing Profiles tool pane.
Profiles Path:
Profiles should be stored in your local private user space:
/home/<your_username>/.config/RawTherapee/profiles
If saving to this path doesn’t work, use the following alternative path:
/home/<your_username>/.config/RawTherapee-AppImage/profiles
Choose Appropriate Profile:
Pick a profile most similar to the site name and date. Alternatively, you can use a profile from any batch as long as it matches the site name and date.
Adjust White Balance & Exposure:
After the profile is loaded, adjust white balance using the "Color" icon:
Pick a light or dark gray area (avoid black, white, or very light gray) for white balancing.
Adjust exposure compensation if needed.
Save Profile:
Save the updated profile with the name of the current batch.
5. Batch Apply the Profile
Apply Profile to Entire Batch:
Ctrl + A → Right-click →
Apply Processing Profile Operations
→Apply
→My Profiles
→ Select your saved profile.If "My Profiles" doesn’t appear, ensure the profile is saved in
RawTherapee-AppImage
.
Review and Adjust:
Scroll through the images to check for exposure consistency.
For any overexposed images:
Shift + Click or Ctrl + Click to select multiple images.
Adjust exposure compensation using the Exposure icon.
.pp3 Files:
Adjustments are automatically saved in
.pp3
files for individual images.
6. Preprocessing the Images
Clear Unwanted Profiles:
For images not worth saving, clear the profile:
Right-click →Processing Profile Operations
→Apply
→Clear
.This ensures that no JPEGs are created for those images.
Process Subfolders:
Ensure both subfolders (
01
and02
) are processed. Once both are profiled, run the preprocessing pipeline:python field_SUNNY_pipeline.py [BATCH_NAME]
Example:
python field_SUNNY_pipeline.py AL_2023-10-06
