Photos
As far as CPD goes, collecting good quality photos of details, is a must, they show so much, old photos show is the detail has worked, new photosshow the way people might be thinking for refreshing details and materials
I have a lot of my personal photos loaded into google photos, but some I have loaded into flickr with sections dedicated to specific areas of interest, Stairs, Bech, Brickwork and so on. Please follow the link and add any comments
Another site I have started to use is Pinterest, where I collect photos from external sources as well as my own on specific subjects. My collection here grows daily, so please drop in and follow.
