As I mentioned before, I took a few pictures as an experiment in sun flare.
I took all of these on my d90 with my 50mm 1.4. They were taken in sequence and all that changed was my aperture, and shutter speed to compensate. I probably could have adjusted my ISO, but I wanted to keep as much the same as possible.
The settings for these first two pictures were ISO 1250, f/8.0, 1/100 sec.
Then I widened my aperture – smaller number equals wider aperture – ISO 1250, f/3.5, 1/1000 sec.
And then I widened it even more – ISO 1250, f/2.0, 1/1600 sec.
Notice how the background, as well as the flare, changes as the aperture widens. Wider aperture = lower number. Also, there is almost no bokeh – blurring of the background caused by wide apertures – in the first few pictures, and is much more pronounced in the last few.
I could have shot some with a much lower aperture, but I really liked the flare I got at f/8.0.
So much you can do with the sun behind your subject. It’s something I’m determined to learn a lot more about… it’s definitely something that needs to be practiced to be perfected.
