Write down what was visible
Use brief observation language such as “edge looked softer in this photo” or “contrast appeared lower under this light.” This keeps the log specific to the sample session instead of turning one image into a broad material promise.
Leave room for a second look
Add a date, a photo reference, and a blank field for a future comparison. A swatch log is more valuable when it can hold uncertainty as well as observations. Browse /updates/ for more maker workflow notes.
