Unsure how he was going to pay his bills with just $90 dollars in his bank account, photographer Daniel Arnold took to his popular Instagram account and threw out a simple offer. $150 for a 4X6 print. Payments could be sent via PayPal and he'd send a release. Amazingly, the plan worked and he raked in $15,000 in a single day.
Instagram has become a powerful tool for artists and companies alike. This story seems to prove that case. You can check out the article here on PetaPixel
