If you want a subtle Blogger theme that puts your photos and words front and center, choose a neutral theme like the Earl Gray Macaron. Your big 650px photos will pop against the versatile grey and white color scheme. And when you decide to expand your blog, there's plenty of room for ads and widgets in the uncluttered sidebar.
