When a photographer shoots an event, copies all the digital files to a CD, DVD or USB stick, and then hands you that disc or USB stick, it’s called a “dump and run” (aka a shoot and burn).
If this happens, it means the photographer has left the job unfinished and expects you, the customer, to complete the work for yourself. For whatever reason, this photographer is either unwilling or unable to do the necessary editing and post-processing.
If a photographer offers a “dump and run” then you should do the same; dump the photographer and run away. You shouldn’t be expected to finish the photographer’s work.
Would you go to Tim Hortons if they sold only packets of coffee and cups of water and expected you to make the coffee? What if your doctor handed you your test results and expected you to interpret them on your own?
A dump-and-run photographer is one who dumps their responsibility and runs away from their work. Why do business with such a photographer?
