Depth of Field
May 19, 2013 07:26:01 #
As you can see this young lady stuck her head in a narrow field of focus. I need some advice on how to widen the depth and still use a fast shutter speed.

Lots of luck! Try higher ISO.

ISO, aperture and shutter duration are three components that work interactively to arrive at the "correct" exposure. Another option which has not been mentioned: a speed light.
The burst from a speed light set to manual + a fractional power can be much shorter than the shutter duration on your DSLR... 1/10,000 of a sec for example. You could position a diffused speed light near where the hummingbird feeds and use an infrared trigger-- or a sync cord (mine is 3'-- some are longer). You could shoe-mount as well. This process could allow a small aperture to control DOF, a higher shutter duration (the short burst will also freeze action) and maintain a lower ISO.

And if I could add to this...longer distance to subject also...both affect the DOF.
For example at f/2.8 and only 5 feet of distance on a 100mm lens...you get a .8 DOF.
If you don't move and only crank the aperture to f/11...it only deepens the DOF to .31 feet. (about 4 inches.)
If leave the aperture on 2.8 and move back 15 feet...you yield a DOF of 1.29 feet.
Just thought I'd mention it...it gets lost in the shuffle some times.

Meives,
Here is the original. I am very grateful that you would take the time, and impressed that you'd know what your were reading. I am a novice when it comes to the particulars of how a picture is put together.
Thanks again,

Dear rpavich,
I thank you very much for your insight. It will be put into the game this weekend. I think the idea that distance is involved in a quantifiable way, and to have the way, will be fun to experiment with.
Thanks again,

I was hoping to see that your ISO was lower. I wanted to say increase your ISO and then tighten your aperature from F 5.6 to F 11 to increase your DOF (depth of field). But your ISO was high. I don't know humming birds, but you may need 1/4000 shutter spead to stop motion the wings. I am not sure aboout the metering? You may have to manual focus or shoot enough times to catch the right focus. Good luck. David

I don't think you should stop the motion in the wings. The photo has more impact the way is, that is for me. Many times you see stop motion and technically thats an accomplishment, however in real time we humans can't ever see the stop motion. Many times I see nature shots, including birds in which all reference to the surroundings is missing. To me it leaves something to be desired. I just love your picture!

Can you estimate how far away you were?
At 187mm
f/5.6
I'm guessing about 36".. :)
