Newbees mostly avoid taking shots that have any recognizable face in it or where model release is needed. By doing this they limit their uploads, expansion and also the earnings. But I have seen many photographers on Dreamstime who are getting reasonable amount of sales from editorial images. It also opens many new doors to cover more subjects. Luckily one of my editorial image just sold for $2.20.
