Antony Bridge and Carl Melegari
I first came across Antony Bridge in the form of his time-lapse YouTube videos about pochade painting, when I was doing research on pochade boxes.
In them you can see Antony painting at various locations in the English countryside and towns, using his small hand-held pochade box, as well as painting small self portraits.
I followed links to the site at pochade.co.uk where he displays and sells his paintings with other pochade artists like Carl Melegari and Ben Spurling, interviews artists who do pochade painting, (including Carol Marine, who I wrote about here), shares a blog with other painters on the site, and also sells the small hand-held pochade boxes he uses. These are made on a small scale basis by a UK carpenter and designer who works under the name of Red Top designs.
