Use a reference scan when monitoring a colour booth print over time
A dated, unaltered capture helps separate material change from editing.
A family photobooth print can shift with age and light exposure. A carefully documented scan gives you a comparison point without pretending to stop the physical photograph from changing.
Record the source condition
Scan or photograph the print once with the highest-quality available method, including a neutral reference and notes about scanner or camera settings. Keep the original file untouched and include the date and orientation.

Store the print separately from the record
Use suitable photo-storage materials and avoid strong light, heat and damp. The digital master supports comparison and access, but it is not a physical preservation treatment. Keep any colour-restored file separate from the baseline capture.
Compare like with like
For a later check, repeat the scan with the same device, profile, exposure and viewing conditions. If those settings changed, note the difference before interpreting colour shifts as deterioration. Do not discard the original based on a digitally enhanced copy. Include scale and a colour reference in the capture, but keep the reference card from touching a fragile print.
