For a long time now I have been, reading, experimenting and trying to get good flash pictures.
And what do I consider to be a good flash picture ? A good flash picture - I mean a picture where one uses flash - is the one which we can't immediately perceive the presence of this device.
Or at least a trained eye can see it but not a "common" one.
You do know what I mean. I hope so.
In the pictures I post I have used this procedure:
I was using a G9 which returns the flash speed sync at 1/500, an advantage regarding the 1/200 on the 5D.s Manual flash, no TTL.
I explain what I have done (please look at the table at the same time):
* To begin with I have measured the light using manual mode and adjusting the speed and aperture so it would fit in the middle of the scale. (first shot)
* I under exposed using a faster speed and allowing the flash to fire at 1/3 of it's power (second shot)
* As I saw that the flash was not enough to make the leaves on the right to pop, I turned the flash to 2/3 ( third shot)
* As I saw that the leaves were too bright for my taste I stepped back a little (fourth shot)
This is called dragging the shutter. Anyone correct me if I am wrong please.
Changing the ISO or/and the aperture would alter the background and its exposure. We don't want that, do we ?
So, when I want to underexpose the background and enhance the foreground with the flash I have to increase the speed to the limits of my camera’s HSS and adjust the flash to my likings on the foregrounds.
If I can’t fine tune the flash - as I couldn't - one steps back or forward decreases or increases the flash power.
Watch carefully: on the 3.ed and 4.th picture the background has the same exposure.
Alis, I know you will understand what I mean by this explanation, won't you?
Now, go to the "field" feed your young with a nice ice cream and experiment, experiment and experiment
I almost forgot to say:
As the HSS is low and the conditions in the Park are very bright you should consider the use of HSS considering however that the power is less that normal flash as the light appears longer. You can even use a ND or a CP filter if you have one.
I wish I could explain this better. Oh my English Brrr...
