Working for time is a co-operation for mutual benefit: The model puts in her (his) time, resources and effort and the photographer does the same. No money changes hands. Both, the model and the photographer cover their own expenses and benefit from each other's skills and talents.

The model's fee consists of photographic images. Typically, the photographs are supplied as digital files, either on CD (time for CD or TFCD), for download from the website (TFDL, time for download) or, rarely nowadays, as prints (PFT or prints for time, sometimes also called TFP time for prints).
