When ever I take pictures on a trip or vacation, i go through them at the end of each day, delete most of them and keep maybe 2 or 3 max, beautify them and the rest goes into the bin. No matter how long the trip, i try to only keep at max the 15 best Pictures. All filler no killer. That way I am comfortable to show others pictures of a trip without boring them and I also like to look at them from time to time as I know those are the best moments.
At the end of each year we create a calendar with photo collages of 4 to 6 pictures per month. The calendar goes to relatives and we create a photo book from the print outs. That is what gets archived.
