Can anyone explain this?? Mongo was testing a ring flash for macro work and noticed the following:-
Same flower taken minutes apart.
First flower (with arrow and marked centre of flower) was taken with the ring flash.
Second flower taken using natural (no flash).
Through the viewfinder, the centre of the flower appears as in the second flower i.e.
the centre of the flower has defined compartments – unlike the first flower (flashed) where the centre of the flower appears fused together.
All variables were the same but for flash – v - no flash. Even tried different angles etc. Several dozen photos later - still the same!
If it is only the behaviour of the when delivered though a flash, then Mongo is in trouble for future flash photos as the non-flash ones are far more accurate.
As a great physics teacher once said, Why is it so ???
