This post is probably going to make everyone laugh!
Thought I have nailed a Eurema hecabe contubernalis (Common Grass Yellow)...but after going thru the checklist, I'm not sure if it is this or Eurema blanda snelleni (Three Spot Grass Yellow).

Experienced a lot of over-exposed shots recently. Is there such things as my flash canon 600 Ex-Rt is too powerful for my 650d? When I set ISO to 100 or 200, sometimes I get very slow shutter of 1/40 or 1/80. This results in blurred images. To overcome it, I increase ISO to 400 and very often the result is over-eposure. My flash is set to ETTL. Should I switch back to 270EX?
