(I read this tip in a blog about a year or so ago. I hope you will be as mind-blown as I was.)
When I was outside on our porch the other day, I was attracted to some tiny drops of sap that were sparkling on a Christmas decoration. I tried to get a picture with my 50mm f/1.4 lens, but it just couldn’t quite do it justice that far back.

Then, I remembered a trick I had read about in another blog. So I took the lens off the camera, turned it around, held it up to the camera, and shot through it BACKWARDS. Instant macro lens! I totally suggest trying this if for no other reason than it will make you feel like a camera Macgyver!

I only tried this with one lens, but I’d be interested to hear if you have tried it with a different one and how it worked.
