Hi Sue. Nice shot of the Iris. No EXIF, what aperture did you use? My tendancy is to use f/2.8 too much giving a tiny DOF. I need to use something like f/11 +.

Hi Lee.  Sorry about the lack of EXIF - I did not pay attention to that when exporting the picture!  The iris photograph was taken with my Sigma 150mm f/2.8 macro lens, at 1/60sec, aperture f/16, ISO 320, and I used the camera's flash for extra illumination.  Sometimes that doesn't work so well, but it did this time.  (I did not yet have my SB-R200).

It is tempting to use the larger aperture, but important to remember the effect on DOF.  For something as large as an iris, even f/11 might not be enough.  At least the focal length of the Sigma helps with DOF, because you are farther away than with a shorter focal length.  I have been experimenting with using whatever "tricks" I can use to make DOF appear larger!

Thanks for the compliment.  I was quite proud of that one myself!

Take care.  Susan
