Have you ever tried to make close-up photos using your iPhone? Yes, it's impossible... iPhone camera has fixed focus so every time you want to take photo of something that is closer that 30 cm the photos come out blurry. I needed to take a lot of pictures of post-it's and I was very annoyed by the quality of the results. I knew that there are some protective cases
with build-in lens that can fix that, but they are too expensive to me.
But today I came across a small magnifying glass in our studio. Hmm. I decided to try it. I attached it to my iPhone with a tape and did some quick test.
The results were UNBELIEVABLE!
I think I'll use it a lot this month (before I can get new iPhone).
