A while back at anhinga trail I was trying for this beauties emerald eyes when another cormorant invaded his/her space!! Luckily I was in AI Server Focus/ Continuous shooting mode so I stayed on that eye and kept the shutter button down. Created in slightly overcast morning light.
1DMKIIN 400DO ISO 400 F11@1/250
Looks like a young bird and what a look into his mouth !!!! You were set with the correct settings and made it work !!! You were slightly off light angle but works very well !!!!
A bit higher shutter speed might have prevented the lower bill motion blur. Man, check out that vein inside the mouth, I also like the marbled emerald eye.
