Keep Upping Quality and Professionalism
When I first stared painting it didn't occur to me to take photos of my pictures but then I realised that I wanted a record partly for historical record but also so I could see my progress over time. My early attempts at photographing my paintings were pretty poor with pictures taken at an angle (flower potting) and low resolution. So as well as learning a lot about colour, composition and painting in general I've also had to learn a lot about photography so that I could populate my social media pages and, later, my website. I've also invested in a photographic scanner to ensure really high quality images for those paintings that I wish to send to a printer for prints or for cards.
For larger paintings I still go to a professional photographer or printers and always to a professional framer ... for many years I used ready made frames and mounts but the difference that a professional frame makes to your artwork is considerable as is the time and stress saved!
