Orange Bluet II

Orange Bluet
This is a shot of up to 1.7x on the sensor for which I used my Canon 500D closeup filter.  I keep it in my shirt pocket so that I can add it to the lens when I need it.  I am learning to know whether I need it by just looking at the distance from the lens.  I can almost see the inner zone where I need it.

Orange Bluet
I have some difficulty including the whole damselfly when using the 500D.

Orange Bluet
I have found that I must be careful about over exposure when using the 500D.  Since I am closer to the subject I must dial in a smaller aperture.  I generally shoot at f/22 or even f/27, the smallest aperture on that lens.  If I still have overexposure, I dial in negative FEC, flash exposure compensation.  The last line of defense for over exposure is to reduce the ISO from 400 down to 100.

Orange Bluet
I have discovered that I can manage to include the entire damselfly by getting to the distant extreme of focus with the 500D.  It seems to me that this picks up where the Sigma 70 - 300 mounted on a Sigma 1.4x converter leaves off at its closest focus.

GNC: Mounting Solar Panels

Gorman Nature Center
I have been wondering when the panels would get mounted.  It looks like it is happening as of June 15, 2013.

GNC Workman
The rails are mounted horizontally.  I wonder if they waited so long to make sure the roof under the panels would not leak.  Does anyone know?

GNC Workmen
It looks like they have a panel up there to check that each one fits.

Citrine Forktail

Citrine Forktail
This damselfly sat there looking at me while my flashes probably blinded it.  It was very cooperative.

Citrine Forktail
Thanks little guy!

The first and third in this series may be misidentified.  I am open to comments and suggestions.  I can't seem to find any damselflies with the orange on the top of the eyes.  It may be a young one.  I am just not sure.

Eastern Forktail II

Eastern Forktail
I have seen several of these this spring.

Eastern Forktail
I used the closeup lens, Canon 500D, for this one.

Eastern Forktail Eating
The little insects on the lily-pads are food for them.

Fishing Spider

Six-spotted Fishing Spider
I know that it is not the color of the one in the book.  It may be a young one.  Please correct me if I am wrong.

It is another creature I saw while watching for damselflies.  This one is just finishing a meal.  The little insect in the top left seems very common and a source of food for others like the spider.

Pond: Things to See

American Bullfrog
I see lots of other things as I sit waiting for damselflies.  This medium sized bullfrog sat about three feet from me the entire time I was there.  I made this shot to show how to identify a bullfrog.  The ridge behind the eye goes back and around the posterior of the tympanum and down.  If it were a green frog, it would go straight down the back.

Green Frog
I saw a cross-eyed bullfrog.

I saw a tadpole which had grown legs and was assimilating its tail.

Eastern Forktail

Eastern Forktail Female
I have seen several of these.  They seem pretty nondescript at first glance.

Eastern Forktail Male
The male is a bit more colorful.  

I have been noticing that I have difficulty manual focusing on these creatures from the side.  I have found that I look at the hairs on the top of the head because there is more detail there on which to focus.  The DOF, depth-of-field, is not deep enough to keep the entire head in focus and I think the near eye needs to be in sharp focus.  I must make myself look at the near eye, without much detail, instead of the hair.  I have been trying smaller f-stops, too.  It is a balance since the smaller one can cause the image to not be sharply focused in appearance, due to refraction.  My lens, Sigma 70 - 300 mm, goes to f/27 but I think that I like f/19 better.  This all depends on the available light, as I am sure you know.  My goal is to have the background darker and the damselfly lit to stand out.  I use flash, as I am sure that you can see.
