The Purples: Actually Getting the Shot
Friday, April 30th, 2010I’ve posted this picture before, but I feel it warrants another view. This is how I looked one day after some serious macro shooting:
Macro shooting isn’t easy. Lots of shot require you to get seriously down into the dirt so that you have the most interesting vantage point. Of course, that doesn’t apply if you’re shooting in a controlled environment with subjects you control, but I like to get out into the countryside and shoot things in the “wild.” And I don’t like carrying around a tripod, so usually it’s just me, my camera, and my lens. There’s always the wind to contend with, and sometimes I sit or lie in the most ungraceful and uncomfortable of poses to wait for everything to be still only to have a mosquito start biting me just as I need to take the shot (important note: it’s possible to ignore mosquitoes that are biting your face. Not recommended, but possible). And then once you’re there, all settled in the mud, you still have to find that one angle that works. A half-inch move to the right can make all the difference. I was reminded of that when I was shooting the little purple flowers that I’ve been posting about here.
I started with this, which is a pretty typical shot for me. I was shooting in aperture-priority @ f/2.8 with my 100mm macro lens. With an ISO 200 and shutter speed of 1/200th, I set the EV compensation to -.7 (almost a full stop darker than the camera thought it should be):

I tend to like slightly underexposed macro shots because I can do so much more with them in the post-processing stage, but looking at this one, I thought that there might be a more interesting angle. I tried to get a little lower to get that flower on the left to take a more prominent role in the picture, but that dark spot that you can see in the top of the photo above became even more prominent. Since I personally subscribe to the idea that backgrounds are just as important as subjects, this wasn’t going to work:

So that meant there was only one thing to do: move to the next flowers. The background looked slightly more promising at a group of three flowers that were to the right of these two. So I took a test shot with my camera still in aperture-priority mode. It’s also important to note that I use spot-metering, so the camera chooses its settings based off a relatively small area in the center of the frame rather than try to expose for the entire frame. So with those settings and with my first attempt at framing these artfullly, I got this:

Meh. Not much I can do with that.
I changed my EV compensation to +.3 and moved around the flower so that the highest bloom was even closer to the camera. At 100mm and f/2.8 and ISO 200, I got a shutter speed of 1/400th for this shot:

Better, better, but that bloom in the back was driving me nuts. Time to rotate around even more and see what I could do about getting a composition I liked. Of course, that meant that the background would change too…

…which it definitely did. It’s almost black, and just a bump in contrast would have made it nearly completely so. But this is definitely one of the benefits of spot metering: because the camera didn’t try to expose for the entire dark frame, the flower I wanted to be well-exposed is (well, slightly under-exposed, but I told the camera to do that). That bloom in the back is still making it hard to let that forward bloom really pop out at you, so time to move again, this time an inch or to clockwise.

NOW we’re getting somewhere! I like how the light is filtering in, but I’m a little worried that the bloom is pointing to the left and the light is to the right. When I think about how I want my eyes to rove over the finished picture, I’m a little worried that the two might compete for attention – the bloom will naturally draw the eyes to the left while the bright portion will draw them to the right. So let’s move up an inch or so and try to put that bright portion behind the blooms:

Well, the bright portion is more where I want it, but leaving the camera set to -.3 EV was obviously a mistake. But look at how you can see the curl of that back bloom now! All that’s needed is to change the EV compensation to +.3 to make the scene brighter…

…and the camera responds exactly the way I want it to. Instead of a shutter speed of 1/1000th, I got 1/250th. Compositionally, the bright bit leads up to the top left, just like the flower. So all I have to do is add a little Lightroom magic (take a look at the two previous posts if you have a strong stomach and lots of free time), and voilà!
