the main body, but also shooting portrait of Still life and other subjects necessary. and large aperture lens and cheap easy to obtain, canon or Nikon and other mainstream SLR manufacturers have 50mm f/1.8 lenses, about 4000 of the price can be bought. Professional portrait photographers in order to pursue better results, will also consider f/1.4 f/1.2 and other lenses, feel the charm of large aperture. A

. Filming at the maximum aperture of the lens makes her face part of the focus, so you need to focus carefully to ensure the eye is smart. Third, choose the lens that best suits portrait photography Generally, the most suitable lens for portrait photography is the telephoto lens between 50~135mm. The focal length creates a blurry perspective and allows you to shoot from a distance of work. This means that a standard zoom lens (such as a 28~80mm) is appropriate for the distal end, and that a te

Angle of View The same concept as field of view 35mm equivalent focal length Crop factor The termsCrop factorAndFocal length multiplierWere coined in recent years in an attempt to help 35mm film formatSlr photographers understand how their existing ranges of lenses wocould perform on newly introducedDSLR cameras which had sensors smaller than the 35mm film format, but often utilized existing 35mm film format SLR lens mounts. Ultra-wide lens designs

P = 50 The algorithm principle comes from the real-time depth of field simulation in the papers "real-time depth" by Guennadi riguer, Natalya tatarchuk, and John Isidoro in ATI labs. This article only describes the principles and procedures. For more information, see the original article.We know that the goal of video games is completely true pictures, but most of the earlier games seem to be missing some pictures, make the image look completely sharp at any a

example to predict the type of contact lenses using decision TreesFirst, we know that building decision trees is a time-consuming task, and even a small data set can take a few seconds to build a decision tree, which is obviously computationally time-consuming. So, we can save the built-in decision tree on disk so that when we need it, it will be read out of the disk.How to serialize the object, Python's pickle module is sufficient for the task, any

UV mirrors use the best you can afford, and the most common lenses are the best with a hood. When I was working in Tibet, I found that some local children had a special feeling for the camera. even developed the habit of touching the camera. and quick and accurate. when you fail, you always win. My most painful experience was that I was accidentally put on the front of the 600mmf/4 long gun by a little devil (the 40 cm MMF/4 shadow was about long; he

Aperture:The English name of the aperture is aperture. the aperture is also called the speed of the lens and the sensitivity of the camera. It is generally expressed in uppercase.It refers to the relative aperture of the lens, not the absolute diameter, so it is easy to misunderstand that the larger the F value, the larger the aperture. In fact, the smaller the value, the larger the aperture.Aperture f = focal length of the lens/diameter of the lens diameterThe important thing to remember is tha

glasses to see the effect is, Red or near-red spectra can only be passed through red lenses, blue or near-blue spectra only through blue lenses, thus separating the left and right eye video. The red and blue videos that go into the left and right eye overlap in the brain to show a 3D stereoscopic effect. Since all the points are made of red and blue two base tones, so the screen color is serious, this way

Video data preprocessing and video data preprocessingVideo data preprocessing Video data preprocessing can be divided into three steps: Video lens segmentation, key frame extraction, and feature extraction. 1. Video lens segmentation (lens boundary detection) Lens segmentation is the first step in video processing and is the basis for subsequent video processing and analysis. The variation of video features in the same lens is mainly caused by two factors: the movement of the Object/camera and t

used respectively. The set lens EF-S of EOS 1100D IS 18-135mm f/3.5-5.6. IS two standard zoom lenses, two relatively low-priced bright and light fixed-focus lenses EF 35mm f/2 and EF 50mm f/1.4 USM shot female portraits in total.The goal is to see how a standard zoom lens, coupled with a lightweight large aperture lens, can extend the expression of the digital SLR camera EOS 1100D.The actual photos are con

has an angle, see the aperture is elliptical, so the light area is reduced. Step 2 Dark Corners are present on any lens, especially in cheap lenses. Professional zoom lens Many lenses, distance from the lens in order to allow the corners of the light to pass, must be done very much. Cheap lenses reduced the diameter of these

Photographer Ziv Koren 　　 Ziv Koren is a senior Israeli news photographer, with cameras to capture the domestic conflicts occurred in the news picture, the works often boarded the international major news media suites. His personal favorite zoom lens is ef24-70mm f/2.8l II USM, in his words: "This is one of the most sharp shots I've ever used, although it's a zoom head, but it has the imaging level of a fixed-focus head." ” The lens, the standard zoom lens of the L series, has a new opti

Today, Fedora8 has been installed. Although it is still the RC3 version, it is not much different from the official version. By then, update is the official version. The overall feeling is not much changed with Fedora7, gnome is changed to 2.2.0, and my support for DellD600 is also consistent with that for Ubuntu. The shortcut key supports adjusting the volume and brightness, But switching the screen and wireless, the buttons such as the optical disk cannot be supported. The overall feeling is t
