Lens Selection
Next, let's talk about the camera selection problem. This is a very troublesome problem and a big problem that is plaguing everyone's nerves.
What should I consider when selecting a lens:
1. image quality;
2. Price;
3. Portability;
4. convenience.
Aside from opening 1 and 2, although some old birds look down on those friends who choose to zoom in the dog mirror, it is obviously a bit funny to

The whitepaper of 3dmark11 highlights how to implement the Lens Effect Using FFT. Here, the lens effects include bloom and extensive light, which are generally done before HDR tone mapping.Traditional
If you don't have the financial ability to buy a big aperture lens, you can play with the blur filter in Photoshop. Lens blur Filter is a very interesting filter, it can well simulate the depth of the lens effect. Do the lens blur to do layer mask or channel mask, otherwise and other fuzzy no difference. Below use two
JavaScript magnifiers are the first component I wrote after becoming a front-end. I learned a lot from them. it has been more than half a year now. I hope to organize and rethink some of the solutions while I still have an impression on myself and improve them, writing these ideas into a magnifier is not a difficult result, but it is complicated because it involves some precise numerical calculations. in the future, I will occasionally write articles about the JavaScript magnifier series. Each t
Learning notes for "Machine Learning Practice": Draw a tree chart use a decision tree to predict the contact lens type,
The decision tree is implemented in the previous section, but it is only implemented using a nested dictionary containing tree structure information. Its representation is difficult to understand. Obviously, it is necessary to draw an intuitive Binary Tree chart. Python does not provide its own tree rendering tool. You need to writ
Magnifier is not a difficult effect, just because some accurate numerical calculation is involved, it is more cumbersome. In the coming days, I will write an article about the JavaScript Magnifier series on a regular basis, each time speaking a point, from the point and face, and finally complete the whole effect.
This time we first learn how to move lenses on thumbnails. (This is DEMO)
Thumbnails and lenses consist of a DOM structure as follows.
Copy Code code as follows:
the logical ratio of the graph is very good to determine, even if the image size changes, we can still see proportionally drawn tree chart.Two. Use decision trees to predict contact lens typesHere is an example of using decision trees to predict the type of contact lenses a patient needs to wear. Here are the general steps for the overall forecast:
Collect data: Use small datasets provided in the book
Preparing data: Preprocessing
Today's share of the tutorials is the latest hot Apple Aperture icon. Drawing an exquisite lens icon is not easy, the light author spent 5, 6 hours, so this tutorial main drawing ideas, of course, very detailed, but need a certain PS base yo. Children's shoes can try, can follow the author's ideas to complete the tutorial, if the whole wood problem, that for their own point of praise Bar.

I would like to share with you a detailed analysis of the mix of a Canon 600D camera with a fish eye.Analysis and sharing:We recommend that you purchase a Canon 15mm fisheye lens, which is cost-effective. At the same time, the Canon 15mm fisheye lens features extremely high resolution, excellent fisheye distortion, vivid color restoration, fast focus, and wide open sharpness with an aperture F2.8. Is a good
Before we discuss this issue, we have to understand what is the reason for deciding whether a photograph is clear or not? There are two main, one is the accuracy of focus, the second is the sharpness of the picture. Sharpness, sometimes called sharpness, is an indicator of the clarity of the image and the sharpness of the edges of the image. If the sharpness is increased, the details of the image are also higher and appear clearer. For example, in the case of Gao Rui degree, not only the screen
Blooming is the optical effect where light from a bright source (such as a glint) appears to leak into Surroundin G objects. The Bloom and Lens flares image effect adds Bloom and also automatically generates Lens flares in a highly effici Ent. Bloom is a very distinctive effect the can make a big difference to a scene and may suggest a magical or dreamlike enviro Nment especially when used in conjunction wi
Generally, the quality of the lens is usually determined by whether the aperture is constant or the focal point is reasonable.I. focal length,The focal length changes the diagonal angle of view. The shorter the focal length, the wider the angle of view, the longer the focal length, and the narrower the angle of view.If a lens has only one fixed focal length, such as EF 50mm f/1.8, It is the fixed focal leng
I would like to share with you a detailed recommendation of photography enthusiasts the combination of lenses used by the Canon 1DX camera.Analysis and sharing:I. Portable, interview, travel, and solutions for taking a picture of the world:(1) Canon EF 24-105mm F4.0L is usm, the price IS 6350 yuan.Advantages: excellent image quality, color and sharpness, fast focus, and powerful anti-shake function.Disadvantage: the aperture is not large enough. The zoom len
