It has "program," "manual," "aperture priority," and "shutter priority" settings!. I know how to change the aperture, shutter speed, ISO, and other stuff, but I don't realy know what it does, and how I should change it according to what I'm doing!. When should I play around with that stuff!? I just need tips! :]Www@QuestionHome@Com Best Answer - Chosen by Asker: Aperture controls the amount of light let in when the shutter is opened!. It is one of the primary determinants of depth of field!. also, it is the primary determinant of exposure in flash photography!. Aperture is the size of the opening when the shutter opens!. Large apertures (lower f/numbers) result in less depth of field!. Smaller apertures (higher f/numbers) result in more depth of field!. "Depth of Field" is the level of focus both in front of and behind your subject in the frame!. Shallow depth of field results in sharp focus on a very narrow plane at the subject and mostly blur elsewhere!. Conversely, deep depth of field results in sharpness from front to back in the frame!. Consider a portrait taken outdoors where the greenery in the back is just a pleasing blur and the landscape photo were the mountains, etc!. in the background are still in focus!. The first one represents shallow depth of of field, the other more depth of field!. Shutter speed helps to determine exposure in non-flash photography!. It is how long the shutter stays open to allow light in!. The faster the opening and closing of the shutter, the less light allowed in!. ISO refers to the sensitivity setting of the sensor!. Higher ISO settings make the sensor more receptive to light, meaning that you can use faster shutter speeds to achieve the same exposure!. It also often translates into additional noise in digital photos!. A good basic photography book should really give you a good understanding of these topics and go into a lot more detail than possible here!.Www@QuestionHome@Com All answers before mine are spot on, and I see no need to regurgitate anything!.
