Playing with my macro lens...

I watched a YouTube video last night about taking a photo with your macro lens but having the subject back-lit with the strong light from the sun behind it.
I quite like the way the spikes have shown up so well with the light behind the cactus plant. I used the flash as well here to catch the detail on the front of the cactus that were in shadow from the sun that weren't showing up in the earlier shots I took.
