I have always really enjoyed macro photography. From the days when I was using my Sony power-zoom camera to my first DSLR.
Actually, I enjoyed seeing macro photography in magazines and books prior to that, but you know what I mean.
I liked that you could isolate a subject that was much smaller in real life.
So once I mastered my kit lenses on my first camera guess what my next lens was.
You guessed it a macro lens! I picked up the 60mm 2.8 Nikon. That lens was sharp! It created great bokeh. The backgrounds just blended and faded away while keeping the subject tack sharp.
Now, true macro is a little more up-close/magnified and with more in focus, but I have my own style.
Tip: I never use a tripod for my macro photography. I use some flash from time to time to freeze the subject and to get more even lighting. I always use manual focus on my lens as it is far more accurate at that magnification level. I find the right distance, lock it on, and try to stay still. You will find that your body will move slightly as you breathe. So I have learned to time it so I get what I want in focus as I move slightly.
Of course that technique isn't for everyone and is pretty hard, but with a lot of practice it can be done. You just have to really know your camera.
The reason I don't like to use a tripod is that I like to get a couple shots and move on to the next interesting subject. As I don't get paid for these photos, I take them for me. I'd rather spend a couple hours and have 40 different subjects than trying to get 6 perfect images.
Tip: If you are interested in a macro lens the longer focal length the better if you are taking photos of insects. It will allow you greater distance from your subject. You'd be surprised how an extra three inches of distance makes you feel much better when taking a close up of a hornet. There are several great lenses out there so if possible rent or borrow one to find the right one for you. Currently I use a 105mm 2.8D Nikon. This lens is both sharp and also works great as a portrait lens.
So if you're looking to stay creative with your photography and to find something new try macro photography. It literally is a whole different way of seeing the world.
It does require some patience, but very fun.
