I LOVE instagram. I love following a diverse amount of designers, artists, photographers, fashion bloggers, nail artists, businesses, restaurants, food bloggers... list goes on. There is so much amazing photography on Instagram and I love seeing new, fresh and interesting work every single day!! Every fucking day, free inspiration and art just flowin' in my feed. It's awesome. Here is one account I love- they update basically everyday and it's always different and new content.
Rad business based out of London and New York, and they sell art/photography books. Everyday they feature a few pages from the books on instagram. They feature such a diverse and cool collection of work spanning decades, topics and styles. From memory, they have featured office furniture catalogues from the 70's, sculptors, food photography, people, street photography, interior designs... so much good shit. I like how much diversity they post, it keeps your head in the game. If you want to see some cool crap on the daily, highly recommend it.
