Funnily I've just sent someone a link to this thread on a car forum.
LOL.... what goes around, comes around
Funnily I've just sent someone a link to this thread on a car forum.
Any given amount of light is called a Exposure Value, or EV
Just one comment:
Surely it's a Light Value or LV. EV is purely a function of shutter speed and aperture. It cannot be related to a light level until it is associated with an ISO number.
Steve.
I raised the point though because it's not just a beginners' mistake to think EV is a measure of light level.
However, if you are going to follow it up with a piece on the relationship between EV, LV and ISO, then this can only be a good thing.
I was very interested to read the section about flash, I've never used a flash before and have just started taking photos of my wife's 40s lindy hop dancing group who do demos in theatres and halls and museums etc. Previously I used the same techniques I use for my ice hockey photos (where flash is forbidden, so high ISO, wide aperture), but after talking it through with a few people on an airshow forum I am a member on, they all said flash is definitely the way to go if I want to improve, which I definitely do. This has given me a good place to start as I have zero experience with flash whatsoever.
I might stick to what I know then and having just bought a 17-55 f/2.8 lens it should become a little easier rather than messing about with stuff I don't know about (at the moment).Flash is useful, but if you're in a big venue, with high ceilings, and nothing to bounce flash off, then you may be better off with fast lenses and high ISO, as direct to subject on-camera flash looks awful in the vast majority of cases.
But why does a small hole (large aperture) have a greater depth of field ?
Glad to see you back!You're welcome
