Spotted this reply on a Youtube Strobist-type video....

" it's the aperture that controls the ambient light most of the time. The shutter speed freezes motion."

:shrug:
 
He must have meant the other way round, but even that's not explaining it that well either.
 
Class, that clears a lot of things up:thinking:

Not sure it should have been the other way round. Aperture doesn't freeze motion..........does it?
 
Ye god's. :(

Perfectly illustrates the need for you to do your own readings/research rather relying solely on others to inform you.

Ask question by all means but do your bladdy own work!

And of course, remember to switch on your personal, built in bull**** detector. :D
 
Yeah, sorry pal, should have elaborated, its been a long morning already!

Your post seemed a little general and sweeping, suggesting some of us may be mis informed/wrong but not suggesting where/how.

I'm a little perplexed Rob to be fair mate, I'm struggling in finding any of the above with my post :shrug:

I'll elaborate though to be on the safe side:

The quote from the video:

"it's the aperture that controls the ambient light most of the time. The shutter speed freezes motion."

Now, the person here has things a little twisted, aperture controls the amount of light allowed through your lens globally whereas shutter speed is the valve for the amount of ambient light allowed through.

To someone who may be starting out, they may believe or consider what's been said in the video and begin to make a lot of confusing and conflicting results.

So, it pays to do your own reading and research rather than rely solely on others to inform you.

Is that any clearer mate?
 
Yeah sorry matey, my bad completely.

I wrongly took your comments to be aimed at us and not the video.

Already its been a long day, if only I could go to be and start again! :lol:

I can kind of understand what he could mean by it in a backwards sort of way.

No worries Sir.

It's looking like one of those days for me too, y'know the kind where a bill is paid only to have another land on the mat, repeat cycle until all money gets farted into thin air :'(
 
Dear oh Dear oh Dear The light from a flashgun be it 1/40000. The time of 25 micro seconds will stop most motions regardless of aperture. Providing there is no ambient light.
 
The comment is not wrong, Aperture does control ambient in conjunction with the shutter and the shutter can be used to freeze motion, It is just misleading and could confuse if the comment was regarding a strobist video and more importantly how to use artificial light to expose a photo.

For anyone that is now afraid to ask for fear of feeling silly, If you need to use flash on or off camera in particular outside generally you would use the shutter speed to control the ambient light or natural daylight which would then leave the subject underexposed. You would then use the aperture and or flash power output to expose the subject correctly...

If you have to use a high aperture and your flash guns are not powerful enough to expose the subject correctly then you will either need higher output studio style flash heads or I think you can up the iso. iirc
