View Full Version : f-stop/shutter speed and possible interesting effects technical question

If you have a choice a range of f-stops - relating to hand-holdable shutter speeds because of decent light (no tripod yet) for a non close-up setting, is there an optimum range of f-stops to use, or does it depend on what effect you want?

And if so, what are the possible effects of high and lower f-stops other than depth of field?

Or are there interesting effects that you can get from really low shutter speeds that require the use of a tripod?

I understand each lens has it’s sweet spot, but are there more tricks to know about?

Can post examples if needed.

Your going to get this response a lot from your questions. Get the book Understanding Exposure by Bryan Petereson. It is a great book that will help you understand the shutter speed/aperature relationship and effects.

You will quickly out grow this book but it is a good investment.

No worries,
that's also a good response for me, cause there's so many books out there - don't know which ones are good and which are not!

Thanks

Understanding exposure is the photographers bible imo.

Sorry....I've never considered photography to be a series of 'tricks'.

Any sufficiently advanced technology is indistinguishable from magic - i.e. tricks.

Take your camera, in Av mode, take a shot of something close with, at at large aperature(small f/#), then take the same shot with a small aperature (large f/#) and check out the difference in depth of focus.

A slow shutter blurs moving objects, great at night for busy streets and such.

Here are a few examples of tripod mount, slow shutter photographs.

Sorry, here's hopefully a simple one,
I can only see ryant's pics as grey squares, am I missing a viewer or is my work computer blocking anything? I get this all the time with images, can see some, not others.

got to agree with the technology and tricks!
