I just answered a question in a certain group forum, and it occurs to me that it may be useful to others. Feel free to ask any questions. So here goes: General rule-of-thumb: expose to the right. What that means, is – use your histogram and get your exposure to the right half without hitting the far right edge. Anything clipped (blown, over-exposed) will be data lost for good. The same goes for black clipping (under-exposed). The reason exposing to the right is better then to the left, is that recovering data/detail from dark areas creates noise – whereas the reverse does not. A little rule that may help you with exposure: / Sunny 16 Basically what this catchy-named rule means, is this: / Given a bright and sunny day outdoors, correct exposure for any scene will be f/16, 1/100 SS, ISO100 (also known as ASA) Working up and down with this you can adjust to suit. For example – a slightly overcast day: / f/11, 1/100, ISO100 (1-stop wider aperture) / or / f/16, 1/50, ISO100 (1-stop slower SS) / or / f/16, 1/100, ISO200 (1-stop more sensitive film/sensor) If you have a specific requirement with SS (stop motion, blur, etc), adjust the other parameters to compensate. To stop your hand motion blur, use the reciprocal of your focal length. Example: 100mm needs at least 1/100th SS. Crop bodies need to be multiplied by the crop. (ask if confused) / If your subject is moving, double SS. If you are also moving, triple it. / Of course using a tripod (and you should whenever feasible) changes this. With photography, each numerical value doubles. / ISO: 100/200/400/800/1600/3200 / SS: 25/60/125/250/500/1000/2000/4000/8000 Aperture can be remembered by using this system: / Use two numbers (f/1 & f/1.4) and double them as you go. f/1, f/2,f/4,f/8,f/16,f/32 / f/1.4,f/2.8,f/5.6,f/11,f/22 Now put them together and you have your full range of full-stop apertures :) Some cameras will list 1/2 or even 1/3 stops. f/1, f/1.4,f/2,f/2.8,f/4,f/5.6,f/8,f/11,f/16,f/22,f32,f/44 Aperture effects Depth of Field (DoF), which is the distance between the closest area in acceptable focus, and the furthest. Choose your aperture to suit your subject/scene. Adjust the other two parameters accordingly. A larger aperture number means a tighter aperture – which means less light. If you ever come up to a situation that has a very high dynamic range (DR) and can’t wait for better light – bracket your shots. That is, expose +/- from the above settings. You can then either decide what you like best, or even combine exposures. (ask how). Of course – if you are a street/candid/journalistic/wildlife style photographer, then you may only get one chance. Which is more the reason to learn the above. There are various filters available to help shoot skies and landscapes – or any scene that has defined high dynamic range. Circular polarisers, graduated neutral density filters – ask. Using additional lighting such as flash adds another element to the equation, and other rules apply. The above is a basic guide to correct exposure for everyday and natural conditions. Hope this helps some people. Feel comfortable in asking anything, or contributing.

The useful Sunny 16 rule always with you! Version printed in black:
-
I took a bucketload of shots like this in the space of about 15 minutes on my way to work one winter morning. I’d never seen fog in 25 years of living in Japan and there was no way I could miss work that morning. Fortunately I had to pass through a park and just kept taking shots until I could delay no longer. I arrived at school with about a minute to spare! There will be more of these when I’ve sorted out which are best suited for this site.

I don’t normally endorse something unless I’ve been there myself; But in this case I will make the exception. / This is for the Adelaide/SA members who are undecided on a great location to MeetUp, yet want somewhere close, relatively inexpensive and perfect for all their needs/wants: It appears one of our newer members to Redbubble and Adelaide/SA works at the Mannum Motel , Mannum Caravan Park and Murraylands Photography Tours! They can reveal themselves if they wish to tell all. But they have given a great idea that would suit everyone, and is fairly priced. This is the program they suggest. On arrival, meet at our conference room when ready / DAY 1 / ... A Night Walk : River / Church / old Buildings / Riverfront (maybe Sunset shots) / Sleep comfortable in Caravan or OnSite Chalet.

Conference room available all the time to meet.
