It really does depend if you like large amounts of text or not :) For someone who does even amount of text and pictures, Tumblr is usually only another social media platform where they can make their posts more available to the general public. If I were you, I would try Blogger or Wordpress, which in practice seem to stand the test of time well.
Of course, if you do prefer just photos, Tumblr might be very good for you- although again, do not just rely on Tumblr for your views. You will only be able to see your followers, instead of being able to track daily statistics, such as on Blogger. Why not look on the websites- Blogger, Wordpress and Tumblr to see what style you like best? Everyone is suited to something a little different.
