Utilising the Compression Effect and Large Bokeh of Telephoto Lenses Bonus tip: For an even creamier effect, move closer to your subject of interest to defocus the background even further. When doing this, use the smallest f-number possible to get the creamiest effect.

Usage example #1: For creating a creamy bokeh effect in the backgroundĮOS 5D Mark III / EF50mm f/1.4 USM/ FL: 50mm/ Aperture-priority AE(f/1.4, 1/40 sec, EV+0.7)/ ISO 125/ WB: AutoĬreating a bokeh effect in the background makes your subject of interest stand out from everything else around it. A small f-number will give you a greater, creamier bokeh effect, while a large f-number will increase the area of your image that appears in focus. The camera sets the shutter speedĪfter you set the f-number, the camera will automatically set an appropriate shutter speed. To use Aperture-priority AE mode, turn your camera mode dial to. Read this for more about ISO Auto mode and ISO speed: To counter that, make use of the ISO Auto mode. When using Aperture-priority AE mode, do note that if you set an f-number that is too big, the shutter speed will slow down and increase the chance of camera shake. The smallest and largest f-number you can set depends on your lens, but generally, prime lenses tend to allow you to set smaller f-numbers than zoom lenses do. A larger area of the image will appear in focus due to the deeper depth-of-field, and this allows you to create a photo where everything in the frame is in focus. (For a recap and examples, refer to Camera Basics #1: Aperture) The area of the image that appears in focus will be smaller because of the shallower depth-of-field, but this means that you can create a bokeh effect in front and/or behind the area that appears in focus.On the other hand, a large f-number results in a narrower aperture. The camera then automatically sets a shutter speed that it deems will result in the appropriate exposure for the user-defined f-number.Ī small f-number results in a wider aperture. In Aperture-priority AE mode, the photographer sets the f-number to a value that he believes is ideal for the image that he wants to create. This is because it gives you control over the aperture setting (f-number), which is a major key to adjusting the degree of background blur (bokeh effect) and the area of the image that appears to be in focus. The range of f-numbers you can set depends on the lens used.Īperture-priority AE mode is a shooting mode that is useful for when you want to create a bokeh effect in your photos, or ensure that everything in the frame is in focus.
You decide on the f-number, and the camera sets the shutter speed accordingly. (Reported by Tomoko Suzuki)Īperture-priority AE mode: Enables you to adjust the degree of bokeh effect Let’s look at this mode in closer detail. Want to create photographs with a lovely background blur (bokeh effect), or perhaps ensure that everything in the image remains in focus? The Aperture-priority AE mode is a convenient mode to use for achieving those effects.
