Female Bullfrog two ways.
I started a bit farther away and slowly crawled closer until I filled the frame with the 180. Females have tympanums (the round ear drum behind the eye) smaller or about the same size as the eye and a white throat.
Once I had this I moved a bit lower and forward and saw that there was a reflection that I liked.
I eliminated the polarizer effect which made the reflection a bit more visible.
The male has a much larger tympanum and the throat is yellow.
This is another with the 100-400 +2.0 extension tube that got some nice froggy detail.
If I am not back with a -2 post, I hope everyone has a great, safe, and enjoyable 4th of July weekend.
