Welcome to the site!

Thank you. : )

Thanks for replying, I appreciate the input.

I have printed the manual, but a beginners book is a good suggestion. Thanks. again! : ) You've all helped me a ton.

As you have probably already determined, aperture, shutter speed, and ISO all work together to provide a properly exposed image. Aperture would be most important when you want to control the depth of field (DOF). If you want a shallow DOF (as often you do with your example of portraiture), you would use a large aperture (smaller number like f/2.8). A landscape would usually require a smaller aperture (like f/11) to get as much of the scene as possible in acceptable focus. When aperture is the priority, the shutter speed is allowed to fall where it may. However, if the resultant shutter speed is too slow, you would need to resort to using a tripod or to raising the ISO. Shutter speed would be a priority where you want to stop action, for example. The aperture, in this case, would be secondary, and ISO would be used to keep the shutter speed up to where you want it. As you said, all of these things depend upon the situation and what you wish to accomplish with an image.

Thanks for replying, I appreciate the input.

Jill - If you haven't already secured a copy of the owner's manual for your camera, which will explain many of the functions you inquired about, in simple easy to understand terms, you can easily do so at www.butkus.org. I'd also encourage you to go to your local library and get a book on photography for beginners, which should again address your questions in straightforward, easy to learn fashion. Then come back here with more focussed questions. There is a learning curve so keep at it until you begin to feel comfortable...we've all been there.

Maybe yes, but within limitations. You 'll develop a feeling for needed DOF someday (an occasional glimpse at tables or online calculators is helpful!). if your AF is more likely to nail an approaching subject at f5.6 than at f1.4, crank up the ISO (if you can).

Hi there, Thanks for replying..

which tables do you mean? and or a calculator?

I have been reading a ton of info online and books, so I feel like I am beginning to understand.

Hi everyone.

Im a first time DSLR user, just recently bought a canon rebel t6i, and Im trying to understand how the ISO, Aperture, and shutter speed play together. I think I might have it figure out but I wanted to ask.

Is the key of which setting to use dependant upon the situation?

It seems that each has several functions but they all relate to light as well. So I was having a hard time distinguishing between when to use the settings. So in short, Aperture for portrait using shutter speed and iso to control light?

Shutter speed when photographing something fast moving for motion or freeze effect and use aperture for lighting?
