For the past week or so I’ve been using a black background for my floral pictures that I’ve been shooting. I’ve been happy with the way it’s been working out. So today I ventured back to the bouquet I bought. I found another purple-ish flower, that I thought might look nice in front of the black background.
I’m not sure what the flower is called. The past few times I’ve picked bigger flowers. This time around, I decided to try using another technique. This flower is a decent size overall, but it is a collection of smaller individual flowers. I wasn’t sure how it would all play out, but what the hell…..give it a try I thought.
I set myself up like usual, and started doing my thing. The difficulty of this shoot was trying to get as much in focus as possible. All the individual flowers, are all on different planes. Meaning that some flowers are closer, some are further away. Some are curved and on an angle.
The thing about shooting close up, is that the plane of focus you get is very narrow. So if you focus on some spot, you might only get a few millimeters in front of that spot and a few millimeters in back of that spot in sharp focus. Then the further away from your focus spot you go, the more out of focus it becomes. The more close up you shoot, the smaller that range of focus becomes.
Here’s the flower I was shooting.

As I said, each flower was on at a different level and at different angles. I also wanted to get as much as possible into focus. I dialed in a large number on my camera for my f/stop. In this particular case I went with f/22. That would allow me to have an area in focus that would be larger. But when you do that, the opening of the lens gets smaller, which lets in less light. So what does that mean? Well that means, that now my exposure time has to get longer. Since the hole is smaller, I have to let the opening stay open longer. In this particular shot, I had to keep the shutter open for 6 seconds.
Now the other thing to keep in mind is motion. When you have a long exposure, your odds of having motion blur go way up. I was using a focal length of about 80mm. So you don’t want to go slower than 1/80 of a sec. And here I am having to use a 6 second exposure. There is no way you can hand hold your camera that long and not get motion blur. I had my camera mounted on my tripod, so that was ok. But you can also get motion blur if your subject moves. Now since the subject is flower it won’t move much you say. Well….no it won’t. BUT, since the exposure is so long, you can’t have any vibration at all, on the floor, or the building you’re in. You can’t move while the shutter is open or the floor and table shakes a very small amount. You can’t breathe in the direction of the flower or it moves. Such small motions that you’d never notice in everyday life, make a huge difference when shooting like this. You have to be careful or the picture turns out blurry.
Overall I’m pretty happy with the way it turned out. I focused on the flowers closest to me. And I think the focus carried far enough back to have a nice effect. The lighting is ok. But I think my favorite part is the contrast between the purple of the flower, and the yellow stamens in the center. On a larger photo you can see much more detail in the stamens.
