The last competition of the year in my camera club is to create a panel of pictures on a particular theme. I have chosen the Royal International Air Tattoo that takes place each summer at our local airfield. The judges like the pictures to be displayed neatly hence the large quantity of rulers, it’s harder than taking the pictures!!
My Dad used to do this with his prints for competitions. Same for his panel when he presented at the RPS. Processed in our dark room at home, printed there and huge precision with mounts, hand drawn lines….. you have taken me back to those days looking at this! Good luck 👍
