Typically, if your subject is closer, you’ll use a lower F-stop number but this also depends on whether you are going for a shallow depth of field or a deeper depth of field. Next, change the F-stop to a value that gives you the desired amount of focus and sharpness. This quickly sets the focus for the camera. To set a proper DOF for your product shot, first change the Focal Distance by adjusting the slider or by clicking the target icon and then selecting the point on your model (or in your scene) that you’d like to focus on. Simply put, Focal Distance is the distance from the camera to where the image is the sharpest and F-stop adjusts the virtual aperture of the camera to determine the extent of the area that is in focus. If you are familiar with cameras and photography, then these two settings should be very familiar and intuitive for you to use. When you activate Depth of Field, by clicking the checkbox, you’ll notice two settings, Focal Distance and F-stop. Just below the Lens Settings and Stereo options, you’ll see the Depth of Field options. KeyShot’s depth of field settings is located in the Camera tab of the Project window. Do this with your mouse by clicking and dragging the Left Mouse Button to rotate and the Scroll Wheel to zoom in or out or by adjusting the various sliders in the Position and Orientation section of the Camera tab. To get started you’ll want to orient your camera to frame your subject as desired. Now, let’s see how this translates to KeyShot. Essentially there are three main factors that control the depth of field: distance from subject, focal length, and f-stop. ![]() This zone varies from photo to photo, some have a very small zone of focus which is known as a shallow depth of field, while others may have a large zone of focus which is known as a deep depth of field. In its most basic sense, depth of field is the zone of acceptable sharpness within an image that appears in focus. KeyShot’s Depth of Field (DOF) camera settings is a simple, powerful option to bring another level of realism to your product shots. Its ability to add depth to a scene is no different and, it’s a whole lot easier. KeyShot has all the features that allow you to capture your scene just as you would with a real-world camera.

Much like Denoise Blend, too much causes details to appear flat and highlights appear to be knocked back, so be mindful to set it just low enough to remove fireflies without compromising your scene detail.īoth Denoise parameters provide a quick method to reduce noisy scenes and typically allow you to achieve highly desirable results in less time. Essentially, what the Firefly Filter does, is remove scattered rays of light in your scene, eliminating them quickly and easily. This parameter can be adjusted with or without the Denoise Blend parameter, however, it does require the Denoise checkbox to be toggled. The second parameter Denoise is the Firefly Filter. However, most surface details will come back provided the scene has enough time to res-up or enough samples selected when rendered out. The larger the Denoise Blend value, the more likely you are to lose fine surface detail such as scratches or subtle matte surface elements. A good rule of thumb is to set this to the lowest value that produces desirable results. Denoise BlendĪt this point, you may notice the Real-time View becomes significantly more blurry due to the Denoise Blend parameter is set to its maximum value of 1. To use either of these effects, select the checkbox for Denoise. ![]() Below that, is the Firefly Filter which controls the degree hotspots and hot highlights are reduced. On top, is Denoise Blend, which allows you to determine the degree of denoise to apply to your scene. When you expand that section, you’ll notice that the Denoise has two parameter sliders which appear greyed out. Just under the Adjustments section of the Image tab, you’ll find Denoise. Luckily, there’s an incredibly easy way to combat these issues, straight from the Image tab in the Project window. KeyShot Denoise & Firefly Removalĭepending on the lighting intensity and materials you’ve applied to your KeyShot scene, you may run into problems where your final rendering appears far noisier than you’d like or has unwanted fireflies. Today, we’ll take a look at KeyShot Denoise and show you how you to use it to smooth out your visuals to produce faster results from your KeyShot scenes.
