I find that my watching the programme on catch-up on the computer, I can pause when I see a paintable scene and capture the image with Windows Snipping tool. I then print off the "photo" and do a sketch of it - here is St Sophia's Orthodox cathedral in Kiev.
I don't paint many still-lifes but was inspired by looking at our "Pebble" tea-pot to set one up on the dining table and have a go. With the addition of a Denbigh cup and saucer and a box of jasmine tea I think it came out well enough - its a very small painting - sketchbook size..
Finally, here are a couple more doorways, both based on photos I found on Instagram (with the photographer's permission!).
