Let The Creativity Flow E-zine

New Kid on the Block


I would like to extend a warm welcome to Peter Leech and his new magazine Let The Creativity Flow, which is aimed at inspiring and promoting creative photography and photographers.



Let The Creativity Flow Magazine Issue 1

Issue 1 was published in June 2013 and contains an article about pixlr, a photography design challenge, exhibits of works by various photographers, pointers to interesting resources, a spotlight on ШHΛT'S THIS ΛЯT, a tutorial on how to create an "Apocalypse Storm" image, and an article about Victor Dennis Purcell. There is also a page of photo humor, which is pretty amusing.



Let The Creativity Flow Magazine Issue 2

Issue 2 was published in July 2013 and contains an article about Apophysis, a photography design challenge, exhibits of works by various photographers, pointers to interesting resources, a spotlight on Fotographically Yours, a book review, references to photography tutorials on YouTube, an article about Brenda Starr, and a page of photo humor. There's also a program called Project 12 that you can register for (or simply do on your own) where a different theme is provided each month for you to learn about and practice with. This month's theme is Bomomo.

Be sure to check out this new magazine. You'll probably learn something you didn't know before. I know I did.
