This was taken on my Galaxy S3 using one of those clip on macro lens attachments. I was very pleased with the results, all things considered. The kit was actually a birthday gift for my sister, which I then promptly borrowed and explored the yard looking for a worthy subject. I later discovered that said sister also took a macro picture of a flower back in her neck of the woods, and it was fantastic! Certainly better than mine. I am humbled, and always in awe of her artistic talent. I’ll see if I can dig up a link to her version and I’ll update this post when I do.
