So, you get yourself a new camera - how important to you is the “reading of the manual” - and do you? Or are you like me and leave it on the ‘easy option’? 

I bought a new camera last year - which has a very good “Intelligent Auto” mode (with face recognition - wow!) - and I’ve hardly ventured off that setting.  Fortunately, I’ve found a very good online forum for my camera (and variations of) and learned folks on there have recommended, rather than having it set at the automatic mode, to set it thus:

(1) Set Auto ISO
(2) Set "P" for the Programed Auto Mode
(3) Set Spot Focus

I’ve been very brave and done that - now all I’ve got to do is to persuade myself to venture out and to remember that: “you’ve got to take a picture or two”!

Hi Trigger.....  Grin

ISO or ASA is how sensitive your film or digital camera is to light.

Remember the ISO is like you pupil in your eye, When there's bright light your eye close's up to reduce the amount of light going through ie: an ISO of 80 - 100 for example.

When your in low light conditions your pupil opens up and allows more light in ie: an ISO of 400 - 800 - 1600.

There is a slight downside to using sutch a hight ISO...... "Grain on the photos".

The Images below show the ISO being used and also the grain effect.

Thanks for that Adee - very interesting - I shall “sail forth” with added knowledge.  Now all I need is for the impetus to get me activated along with the camera!  Grin

Program mode "P".

Program mode is similar to Auto but gives you a little more control over some other features including flash, white balance, ISO etc.

In auto mode your camera makes just about all the decisions for you, the camera handles all of that for you. Most of the time it does a pretty good job.

I myself sometimes use "P" and then use the F stops to increase or decrease the amount of light coming through.  Smiley

The second Image shows where the F Stop Display is. By Moving it to the left it will darken your image (Longer speed needed), or to the left to make it brighter.

So does switching the camera to 'Programme Mode" mean that I'm actually going to have to think what I'm doing?  Could I point out that multi-tasking is not amongst my very few abilities!

But seriously, when I post any pictures (to begin with at least) taken using that facility, I will mention that's what I've done.  So, as they say "Watch this space" - but not for too long!

I normally b*gger it up first Trigger then RTFM (read the manual) and still b*gger it up. I constantly manually under expose as the cameras often get it wrong. I've noticed that the EOS-40D is no where near as good at metering as the EOS-5D MkII so i'm now learning how to uncompensate myself for the 5D Smiley

Well, at least I'm not alone!

Adee, I feel I must comment on your explanation of  ISO or ASA/DIN.  This is actually the speed of the emulsion on films i.e. its sensitivity to light and nothing to do with the amount of light actually reaching the film. This is governed by lens aperture (f-stop) and shutter speed.   I appreciate these ISO settings are also used in digital cameras and do have the same effect on the grain in the picture even though no 'film' is in use.
