"摄影师若是遇到能让自己的特长发挥得淋漓尽致的模特,便不会过分追究照片上展现不出的性格缺陷。" I'm not quite sure if this is indicating that the photographer wouldn't excessively pursue personality defects in the model or if the photographer wouldn't excessively pursue defects in the feeling the model is supposed to present. The model in question has many.....personality defects
[If the photographer could find a model that could fully display her specialities, he wouldn't focus much on the personality of the model that wouldn't be captured in the photo.] This is my go~
