thank you very much!!

I will let you in on a little part of knowlege that I will cover in part 3...

in order not to have blurriness due to hand shake,
make your shutter speed the same as your focal length.

for example, if you are using a focal length of say 55mm.....
then aprox 1/60 shutter speed is what you can hand hold your camera.
this is typical of a person who can hold the camera as steady as they can..
of course if you have shake reduction, you can go lower... for example 1/30 or lower if you have a very steady hand

Just wanted to thank you for your explanations Randy! I just got a new camera for Xmas (nothing too fancy, just a Canon A630) that has just enough settings to get me learning, then I plan to upgrade, once I get a little better. Your explanation has by far taught me more than any other and I've been reading on the subject on and off for about a year! Thanks again! Looking forward to more!

I can't thank you enough...that actually makes sense! Is there a standard combination to start on? Also I think I will have to wait for part 3 regarding focal length...not sure about that. I mean I have heard it used, just not sure what it is.

Thank you so much for taking the time to explain all this. It's a lovely sunny afternoon, so I might just go outside and "play".

Krys focal length is the length of the lens, if you have a zoom lens it might say 24-70mm that means it will zoom from 24mm through to 70mm so if you were hand holding the camera and had the lens zoomed to 70mm then you would need to have a shutter speed that was faster the 1/70th of a sec to combat camera shake
But if you have image stabilised lenses then that is good for another couple of stops
Hope that makes sense

what you do is set one or another..... If you set your camera to a certain F stop, your camera (in apeture priority mode) will automatically select the shutter speed to get a good exposure

If you put your camera in shutter priority mode, once you select the shutter speed you would like, then the camera will automatically select the proper Apeture for good exposure.

I would suggest any shutter speed below 1/30 of a second you should use a tripod.
I am going to post a suggestion guide for shutter speeds

Here is a chart on "suggested" shutter speeds for stopping different actions.
It is from an old kodak photoguide book

SLOW ACTION--> 1/125 second

People walking
Children playing (not running around)
Babies not holding still



MODERATELY FAST ACTION---> 1/250 second

Joggers
Swimmers
Bicyclists at medium speeds
Horses running at a moderate pace
Parades
Running children
Sailboats
Baseball and football players running at a moderate pace
Skaters
Slow moving vehicles



FAST ACTION-----------> 1/500 second

Fast moving runners
Running horses at a medium distance
Divers
Fast moving bicycles
Moving cars in traffic
Basketball players
Baseball and football players moving at a fast pace



VERY FAST ACTION--------> 1/1000 To 1/2000 or higher

Race cars
Motorcycles
Low flying airplanes
Speed boats
Field and track events
Tennis players
Skiers
Golfers

** Please note**

In order for proper exposure for high shutter speeds (example 1/1000 or more)
there USUALLY needs to be a very bright light source like a sunny day

hope this helps

Ummm, I have a 12x zoom lens. Also has image stabilisation.

I love all your explanations, Randy! They're wonderful! I 'get' most of it, but your explanations have clarified things even better for me!

[ima]

WOW... thanks for your explanation, Randy! The best explanation I have ever read!!

[GailS]

Randy, I love this thread and your explanations....years (and I mean a lot of em) ago I took a photo course in college but got away from all the jargon and settings. I'm ready to get back into it, and you are a marvelous teacher...some of it is coming back to me...and some I see I still need to learn!! Thank YOU!!!

HI Krys2280

your 12x zoom lens on your S3 is equal to 36mm – 432mm (in 35mm terms)
If you did not have image stablisation, at 432mm you would have to much handshake...
the long end of your zoom lens "magnifies" hand shake, making it difficult to get a blur free image.

cheers

Could these explanations be made into printable tutorials maybe????

[Avril]

wow Thanks Randy for all the info...needless to say I have printed it out
so I can study it slowly and take it all in...

[Avril]

Thanks Karen for you infor too...I have learnt so much today!
