JS: For editorial, the rates are set by the publication and they can fluctuate from $500 to $1500 not including expenses (travel, meals, assistant, equipment, etc). In terms of commercial projects, the rate should be dictated by the usage- the more usage, the higher the rate- again not including expenses.
EG: From my IG stories.
CC: The numbers that Emiliano shared above are spot on based on my experience. If a client asks you this question, my next questions are always “Can you tell me how many images will be delivered, how and for how long the images intend to be used? Is there a budget outside of the day rate for expenses (assistant, equipment, retouching, etc.)?” Ask for help and make sure it’s a fair exchange.
