By using this effect, we can focus on and sharpen a specific object that interests us, while blurring the entire background around it to a greater or lesser extent. We can also simply blur just the foreground or just the background. We can also apply a very subtle depth of field effect in regular visualizations, not just close-ups, but in typical standard views to gently enhance the realism of the visualization. This effect needs to be really very subtle so that our entire visualization isn't too sharp or too vivid, but rather just minimally so. Blurred. However, you have to be careful because it's very easy to overdo it, and as a result, the visualization will just become poor quality. To discuss this effect with a specific example, I created a new camera that zooms in on the Louis Vuitton case we imported from BlenderKit. The depth of field effect is enabled in the camera settings. At this point, we have several options to choose from. The first step option is focus on object. Here we can choose the object that our camera will focus on, and everything around it will be blurred. We select our case, and at this moment it is assigned as the object that will draw the attention of our camera. The depth of field effect is not visible in the preview at this moment. To change this, we need to expand our view and select the object in the settings. In this place, we enable the depth of field. We can collapse this and slightly reduce the view back. And at this very moment, we can see that all the objects outside of our case have become slightly blurred. To increase the blur, we need to change the value in the F-stop. Basically, the lower the value, the greater the blur becomes. The higher the value, the more subtle the blur is. The default value is set to 2.8. We'll reduce this test value, for example, by half to 1.4. Thanks to this, we can see that all the elements that were blurred have become even more blurred. The effect of this is that our case becomes a bit more blurred. In some places, of course. It's worth noting the model itself at this point. It's important for the origin of this model to be in its center. At this moment, everything here is correct. Just to be sure, I'm setting the origin once again to the geometry, but everything seems to be fine. Going back to depth of field, we select our camera. As I said before, the f-stab values are the values. The most important ones, that interest us the most. Below we have options like blaze rotation and rotation. They are responsible for this. It's just a purely cosmetic appearance of our blur. We won't worry about that, because in the end, it doesn't have a big impact on the effect. We'll initially leave the F-stop value at 1.4 for now. We'll switch back to the previous camera. I currently have the proportion set to 1 to 1, which is how I ended the previous lesson. And in this example, we'll discuss another option, namely Focus Distance. Focus Distance. This is an option that serves as an alternative to focus on object. At this point, we can also specify a particular object that our camera will focus on. In this case let's choose for example the kitchen cabinet and after the selection the distance at which the cabinet is located from our camera will be assigned. This distance is expressed in centimeters. To see the effect of this blur I'll gently move the camera closer. Move it. We can see the blur on our battery. Something is appearing here. Our cabinet is also slightly blurred. And our camera is focusing on our kitchen cabinets. By juggling the f-stop value, we can of course increase or decrease this effect. As I mentioned a moment ago, an f-stop value of 0.6 causes quite a bit of blur in the foreground. The hats in the background remain sharp. We can certainly enter it manually. But it's quite difficult to gauge how far the object is from our camera. However, we can test this value. Then you will see that the lower the value, the closer the camera focuses. and in this case the elements in the foreground will be sharper. In this case we can see that the panels here are sharp, while the background is more blurred. If we decrease the value, then our entire foreground will become more and more blurred, and the background will practically become completely invisible. In turn, by increasing the value, everything will become sharper. Until we eventually reach a higher value once more, where the foreground will be blurred and the camera will focus somewhere far behind the cabinets. We can try leaving the value as it was before, meaning from our kitchen cabinets and set the f-stop value quite high, for example, at 4. This should essentially give us a slightly subtle blur effect in our scene, which at first glance will be completely invisible. Which will add a bit of realism to our scene, our visualization. That's all when it comes to the depth of field effect. In the next lesson, I'll show you how I set up the cameras in my scene based on everything I've talked about in the previous lessons.",
