I think you are trying to take on too much too fast.
Not really. How is that possible? I'm talking
about two of the most basic modes on the
speedlight according to the instructional video
I have been watching.
I bought a speedlight. I want to use it.
There are several different settings on a speedlight
I may never figure out. But, if I am going to use it,
I need to learn the basics.
I think I did learn the essence of two very basic
modes. I also think I was pretty spot on with my
original description of how the two modes work.
I watched several videos that gave the same
explanation. Perhaps the fault lied in how I
Thomas' explanation above is exactly how I
understood the video. However, the video did describe
using spot metering (selected on front of camera) and
TTL to give more precise lighting to whatever you are
putting into focus (aka a smaller area). At least, this is
how I understood the process.
I also learned that you can bounce light off a wall or
ceiling (as long as it is white), however you need to
keep your subject close to the wall as the bounced
light will deteriorate the farther away that subject is.
If I understand correctly, If a subject is next to a
window and the light coming through that window
illuminates one side of the face you can place your
speedlight on the opposite side of the face to balance
out the lighting.
Not trying to digest this too fast. Just want to be able
to plug a speedlight in and at least know how to do
something with it.
...and I understand I may not be getting this 100%
right as there are many variables to consider. However
I do appreciate you guys correcting the things I don't
understand or are improperly explaining.
