Yes, you can use multiple cameras for a project! Just ensure photographers follow the proper procedures when photographing the camera cards and upload the images as usual.
Snapizzi uses EXIF data from the image files to identify multiple cameras and index the project correctly. If your workflow involves renaming files before uploading, make sure filenames have leading zeros (e.g., 0001 - 9999) to avoid indexing issues. Additionally, ensure that all the camera time settings are correct for accurate timestamps.
