С какими фотобанками и микростоками лучше всего начинать работать фотографу или иллюстратору?

Я бы порекомендовал вот такой список:

1. Shutterstock
2. Istockphoto
3. Fotolia
4. 123RF
5. Dreamstime
6. Bigstock
7. Depositphotos
8. Vectorstock
9. Crestock
10. Canstockphoto
11. Creative Market
12. Envato Graphicriver
13. Pond5

Можете поподробнее вот тут прочитать https://supermicrostock.livejournal.com/312.html

К списку выше дополнить сложно. Скажу одно: с отечественной "Лори" сотрудничать не советую. Мошенники.
