I'm not sure I would include digital photography on the list.
I prefer that spelling, too.
In engineering, a “FILLET” (2 L’s) is pronounced exactly as it looks like in English (not that French pronunciation), and means a rounded corner.
Unlike a chamfer, which is a simple cut-off type corner.
BTW, I change the oil. My husband doesn’t get into cars like I do - but he could do it. Just never cared to and doesn’t know how yet.
