The #AREKUchallenge is an ongoing photo-competition arranged by AREKU, to inspire other photographers to showcase their works to a broader audience and receive important feedback in order to become even better at their craft.
The challenge is theme-based, and is often going on for a month, with a new theme announced each month together with the most prominent works of the past month.
To participate, a user simply upload their best interpretation of the actual theme to their Twitter and / or Instagram-profile together with the hashtag #AREKUchallenge. For a submission to be accepted, the user also needs to be following the accounts of AREKU.
