Additional AUTO ISO information
In tip #20 I talked about setting the Auto ISO up so that it would only go up to a level that you find acceptable and not go beyond. I also talked about setting the minimum shutter speed. This tip is to give you some additional information concerning these settings.
Additional information you might find useful.
The default for the highest Auto ISO is 6400 if you do not go in and choose to lower this in the menus. If you are in "P" mode or Program mode, the camera will have control over the shutter speed and the Aperture or "F" stop being used. If you are using "A" or Aperture mode, which I use a lot, the camera will control the shutter speed and you will have the control over the aperture or "F" stop. In either one of these modes if your camera reaches the maximum ISO that you have set and still cannot get enough light the camera will actually override the minimum shutter speed and go lower to be able to get enough light to get the picture. You need to be aware of this because there is a potential of going to slow a shutter speed and blurring your picture.
There is also one other piece of information that you might find useful. After you set the maximum auto ISO setting that you want you can also pick the minimum ISO that you would like the camera to use. let's say that you have chosen the max AUTO ISO setting to be 3200, you can now go back and choose for example a regular ISO setting of maybe 400. When you do this you camera will shoot everything from a min ISO setting of 400 up to the max setting of the 3200 that was set in our example. Any time you are in AUTO ISO the camera will always try and use the lowest ISO that it has available to get the picture that you are trying to take. Hope you might find this additional information helpful. Jeff
This is a corrected post. In the original post I had written up what "A" and "P" mode do backwards. I made the mistake of trying to write up a tip while keeping track of the storm Isaac on the TV. I just want to give a BIG THANK YOU to Raymond for reading my tips thread and sending me a PM asking about it. I have swapped what the two modes do in the post so that it now reads correctly. Sorry about any confusion about how it was written up. Out of 38,000 views and 69 tips I think that this one is the first one I have had to correct and feel very lucky about that. I knew sooner or later it would probably happen. I read every tip several times and check them before posting so that you can rely on the information to be accurate.
I would like to thank all of the people that take the time to read my tips and also for the many positive E-mails and PM's I receive about them. One more time, thanks to Raymond for asking me about the tip so I could correct the information. Jeff
