I'm very impressed by the powerful search engine DT provides to designers; so many little details that make one's job easier and give everyone a chance to find the right photos for the right project.
For instance I like the fact that when you upload a model release, you specify the age of the model, allowing designers to refine their search to specific age brackets.
I guess that many of us have favorite models that we will hopefully keep on photographing for years. Cute baby Melba, photographed here at the age of 6 months, will soon be 1 year old. Although DT recommends to only upload one MR per model, I'm thinking of uploading a second MR for her when she hits that age, so that her baby photos remain in the "less than 1 year" age group whilst her new pictures appear in the "1-4 yrs" age bracket.
In my opinion, uploading only one MR for Melba would mean that a designer looking for a 1 year old baby might still see Melba appearing on his/her search when she is 3. Conversely, a designer looking for a cute 3 year old and refining his/her search to this specific age group might never see her pictures, if I was still using her initial MR then.
I'd love to read your thoughts about this matter.
