big aperture and small aperture lens difference

A larger f-stop adjustment for DOF will bring a much larger focal point for the entire image, foreground and background. The aperture range identifies the widest to smallest range of lens openings, i.e., f/1.4 (on a super-fast lens) to f/32, with incremental stops in between (f/.A smaller f-stop adjustment for DOF will give you a smaller focal point, normally seen as a portrait of a person in focus (foreground) and a blurred background.The bigger the hole, the more light that comes through onto the. Depth of Field: Adjusting the aperture size will also control your images focal point. Aperture refers to the size of the lens opening which is measured in f-stops, from a small hole wide enough for one. Aperture is the hole in the lens that gets bigger and smaller depending on your settings.Wide lens apertures will produce shallow depth of field, while small. A larger f-stop will limit the amount of light which you may need to adjust on a bright sunny day depending on your intended shot. Your choice of lens aperture controls how wide the area of acceptable sharpness is.With landscape photography, you want to go narrower, like f/8 or f/11 to get everything from the foreground to background in focus. The focus can be shallow and only the eyes can be in focus while the ears are a little softer and the background blurry. A smaller f-stop will allow much more light into the sensor, this is great for dark shots taken at night. In a portrait, a really wide aperture like f/1.4 can flatten the depth of field dramatically.A small aperture does just the opposite, making a photo darker. A large aperture (a wide opening) will pass a lot of light, resulting in a brighter photograph. a 100 mm lens with a 25mm iris and a 40mm lens with a 10mm iris are both f/4. Exposure: Adjusting the aperture size will directly affect how much light passes through the lens and reaches the image sensor of your camera. As aperture changes in size, it alters the overall amount of light that reaches your camera sensor and therefore the brightness of your image. The aperture of a lens is the focal length divided by the size of the iris.There are two things to consider when choosing/adjusting the aperture size for your lens, your Exposure and depth of field. This is the size of the aperture on your lens. You may have noticed numbers like f/1.4 or ranges like f/3.5 ~ f/5.6 printed on your lens. The counterintuitive effect of using ratio to measure aperture is, the smaller f-number, the more light is let into the camera.
