Read fees and rights together
A reasonable entry fee can become a poor choice if the rights language is broad, the production requirement is expensive, or selected artists must cover shipping, framing, installation, travel, or publication costs without enough benefit.
Look for refund rules, late fees, image usage terms, credit requirements, and whether the organiser can use submitted images beyond promotion of the specific award or exhibition.
Look for signs of accountability
Trustworthy calls usually name organisers, venues, jurors, partners, sponsors, selection dates, and contact routes. They also explain prizes, finalist obligations, and what happens after selection.
Missing contact details do not always mean a call is bad, but they should make you slower to pay and more careful before sending unpublished work.
