Bloom is a lighting artifact of real-world cameras that also adds to the perceived realism of the rendered image by reproducing glow around lights and reflective surfaces. Bloom is an effect that works with other effects, like lens flares and dirt masks, but those are not covered by the general bloom properties.
Defines the opening of the camera lens. Aperture is 1/f-stop. Typical lenses go down to f/1.2 (a large opening). Small numbers have a larger aperture opening, blurring more of the foreground and background. Larger values have a smaller aperture, blurring less of the foreground and background.
The Camera Calibration plugin provides simplified tools and workflows to calibrate a camera and lens in the Editor. This calibration process generates the data necessary to accurately align the virtual camera with the physical camera's position in space, and to model the lens distortion of the physical camera. The plugin introduces the Lens File asset type which encapsulates all of the calibration data for the camera and lens.
You can select the calibration algorithm that is used to compute distortion parameters and camera intrinsics. The plugin includes the following algorithms, which rely on OpenCV to calibrate the lens using a set of 3D-2D point correspondences:
You can manually adjust the location of the image center after you calibrate the lens. This can be useful when the interpolated image center between two calibrated focus or zoom points is not accurate, or when external factors, such as temperature, affect your camera lens slightly.
With dual-pixel phase detection autofocus, the rear camera can focus sharply in almost any scenario. Add the fast f/1.7 aperture lens with image stabilisation and pictures in low contrast light are usually sharply focused and blur-free.
This app also offers other blurring effects such as radial blur, background blur, lens blur, etc. You cannot exactly call Picsart a motion blur effect app. It also has other blurring effects and editing tools. However, these wide arrays of features make this app very popular among its users.
I understood this when I finally managed to get nice bokeh with my kit lens (I still did not have my beloved 50mm f/1.8). I used to practice my photography, and background blur on a tree. The f/3.5 aperture was not good enough for me so I tried different things. The first satisfying bokeh I got was when I focused my camera really close to the tree. 2b1af7f3a8
